Bohn’s Boner and the Power Plant Precipitator Computer

Up front, I would like to clarify the title so that those who are quickly perusing articles looking for something salacious won’t have to read too far before they realize this isn’t what they are seeking. The word “Boner” in this headline refers to a “joke” played on a Plant Engineer by the name of George Bohn at the coal-fired Power Plant in North Central Oklahoma. When I was a boy we had a joke book called the “Omnibus Book of Boners”. Most of my life I never thought about the word “Boner” as having another meaning. Which, after this joke was played might have explained the expression on George’s face.
Joke Book
In an earlier Post “Power Plant Humor and Joking With Gene Day” I explained that when playing a Power Plant joke, the longer it takes to play a simple joke, the better the effect. I think the reason for this is that when the person realizes that a joke has been played on them by a fellow Power Plant Man and even though it was simple, the person went through the effort over a long period of time, just to make you smile for a moment. Then you know that this person must truly be a good friend. Who else would waste countless hours on someone over days, weeks, or even months, just to make someone smile once?
Well…. Bohn’s Boner lasted for over six months! Yeah. Six months, at least.
I saw the opportunity arise one day after we had received a new hard drive for precipitator computer for Unit 2. We had the computers for a couple of years after we went to digital controls in the precipitator before the hard drive crashed. This happened to be a project that George Bohn had managed. He was the project manager and had overseen the installation of the precipitator controls, which included the two precipitator computers in the control room. One for each unit. They sat around behind the big control panel that you see when you watch an older movie about a Power Plant Control Room, like the China Syndrome.
I love this picture!
Anyway, each of the computers had 30 Megabyte hard drives. Yeah. You heard that right! 30 Megabytes. That’s not a typo. Not Gigabytes… nope. Megabytes. Just this morning at Dell, I received an e-mail with a file attached that was over 30 Megabytes in size (Thanks Norma). I’m talking about an IBM AT computer:
IBM PC
Well, the Unit 2 precipitator computer was used to monitor all of the 84 control cabinets in the Precipitator control room. It indicated how much voltage and amperage were on each cabinet, as well as the spark rate, and the setting on each cabinet. It was really a great step up. I’m sure today you can probably do that from your phone while you are sitting in a movie theater just before they tell you to silence your “Cell Phone Now” and stop texting your neighbor. Back then, it was amazing.
All the operator had to do was go over to the computer, pull up the screen (this was before Windows, but the program was running by default), and type the keyboard command to tell it to print and “voila”, it would print out all that information. The operator could look at it to see if there was a problem, and if not, he just saved it with all the other reports he was supposed to create during his shift.
Believe it or not. Before this time, the operator actually walked up to all of the 84 cabinets on each unit and looking at meters on the cabinet wrote down the voltage and amperage of each cabinet on a form. You can imagine how much happier they were to be able to print it all out in the control room. Hours and hours saved each week.
So, when the 30 Megabyte hard drive crashed George Bohn ordered a new hard drive from the IT department in Oklahoma City. A couple of weeks later, we received the new hard drive from the city. George gave it to me and asked me to install it in the computer.
When I installed the hard drive, I found that it had already been formatted. All I had to do was install the program and we were good to go. I backed up the program from the Unit 1 computer and copied it onto the new hard drive using a floppy disk. Yeah. Programs were a lot smaller then. A 360 Kilobyte floppy disk was all that was needed to hold the entire Precipitator program.
I noticed right away that instead of being the 30 Megabytes we had expected, there was only 20 Megabytes on the drive. That was all right with me. 20 Megabytes would be enough so that we didn’t have to back anything up very often.
As I was installing the program and testing it, and going through the code figuring out how to change Unit 1 to Unit 2, I had an idea…. At the command prompt, I typed “D:” and hit enter. You know what I was checking, right? D colon, and enter…..
sure enough. there was a D drive on this hard drive. Another 20 Megabytes were on this partition. You see. This was actually a 40 Megabyte hard drive that had been partitioned as two 20 megabyte drives.
It was at this point that I thought I would play a little joke on George. I figured he would come and look at this computer and at first he would find that the new hard drive was only a 20 Megabyte drive instead of the 30 Megabyte drive that he had ordered. I also figured that like me, he would think about it for a minute and then check to see if there was an extra partition and would find the extra drive.
So I thought I would leave him a little present. I went to D Drive and at the command prompt (gee… the only thing you had was a command prompt. You didn’t even call it a command prompt then. You called it a DOS prompt) that looked like this: D:> I typed – “label d: Bohns Boner” For all you older DOS people, you know what this did, right? It labeled the D drive volume name “Bohns Boner”. At the time I think we were on DOS 4.0 or something close to that. The volume length was limited to 11 characters and Bohns Boner took exactly 11 characters. The label couldn’t be longer than that.
Now, all I had to do was call up George Bohn, tell him I had installed the hard drive in the precipitator computer and it was up and running and go to the electric shop and wait for him to come down with a smile on his face over the name of the second drive on the computer. So I did. I told Charles Foster and Terry Blevins what I had done.
After the reorganization, Tom Gibson, our Electric Supervisor had decided that Terry Blevins would maintain the precipitator on Unit 2, and I would maintain Unit 1, which was great for me, because I was no longer working on both of them by myself. So, Charles and I were waiting for George to arrive in the electric shop office. It didn’t take long.
George came in the office and said, “Did you see that they only gave us a 20 Megabyte hard drive instead of a 30 Megabyte drive. (Oh. So, he hadn’t found the second partition). I replied, “Yeah. I noticed that.” George was a little perturbed that he didn’t get what he ordered. He said he was going to contact them and have them send us a 30 Megabyte drive. We had paid for it. I told him that he should. Especially since we had paid for it (keeping a straight concerned look on my face).
Anyway, a couple of weeks went by and there was no new hard drive, and George hadn’t said anything more about it. I thought he might have eventually found the second drive, but then he would say something like “I can’t believe they didn’t send us the right hard drive” and I would know that he still hadn’t figured it out.
One day the operators came to me and pulled me aside and asked me if there was some way when they were on the night shift if they could use the precipitator computer to create documents. At this time PCs were pretty sparse. The only good computers in the control room were these two precipitator computers and the Shift Supervisor’s office. the Precipitator computers just sat there monitoring the precipitator all the time, even when no one cared. The control room operators had been told not to use the precipitator computers for anything except looking at the precipitator controls.
The plant had purchased so many licenses to use Word Perfect, a word processor that was the “in thing” before Windows and Word came around. So, I installed Word Perfect for them on the extra drive on the Unit 2 precipitator computer. That is, Bohns Boner. I explained to them that they could only use it when George Bohn was not around, because he didn’t know the drive existed and I wanted him to find it himself someday.
Word Perfect for DOS
Everyone agreed. All the Control Room operators that were at all interested in creating documents, like Jim Cave and Dave Tarver and others, knew about Bohns Boner, and knew that it was a secret.
The Control room had a laser printer installed next to the Shift Supervisor’s office so they could print out Clearances and have them look nice. They had some new Clearance system they installed, and this came with it. So, the next question was… Is there a way we can print our documents out using the Laser Printer instead of the clunky Dot Matrix printer tied to the Precipitator computer?
I ordered a 50 foot Printer cable (I paid for it out of my own pocket) and kept it coiled up under the small desk where the precipitator computer sat and explained that they could just disconnect the dot matrix printer on the back of the computer and plug the other end into the Laser Printer and they could print out nice neat looking documents. But… They had to do it at night or when they were sure that George Bohn was not around because he still didn’t know the extra drive existed. Everyone agreed. They would have to string the printer cable across the Control Room floor to reach the laser printer.
50 foot Power Plant Parallel Printer Cable
Like I said earlier. this went on for well over 6 months. It seemed like almost a year. Then one day, George Bohn came down to the Electric Shop office while Charles and I were sitting there for lunch. He said that he had asked Oklahoma City about the hard drive again, and they had insisted that they had sent the correct hard drive to our plant. Then we could see a light go on in his head. He said, “Do you suppose that they partitioned the disk into two drives?” (Bingo! He had figured it out). I said, “Could be.”
Charles and I sat there and looked at him while we ate our lunch. The cherry tomatoes Charles had given me tasted especially good with my ham and cheese sandwich that day. I knew that we were finally only minutes away from the end of the joke we had been playing on George for the past so many months. George leaned back in the chair with his thin long legs stretched out and his hands behind his head. I could tell he was thinking about it.
Then he rose from his chair and headed out the door. Charles and I smiled at each other. We both waited. A few minutes later George came back in the office. He had found Bohns Boner. You see. When you went to a drive back then on the command prompt, the first thing you would see was the volume name. So as soon as he typed the D colon and enter, it would have said “Bohns Boner”.
George sat down in a chair. He didn’t say anything. He just sat there with a straight face as if he didn’t know what to think. I thought…. well, he is an Engineer. Maybe he doesn’t know what to do when Power Plant Men play jokes on them. He looked like he couldn’t decide whether to be upset or glad that we had an even bigger hard drive than he ordered. I don’t know if he ever figured out that the longer the joke takes, the more we liked him.
I guess George felt foolish that it took him so long to find that extra drive. I suppose he might have thought he knew me well enough that if there had been an extra drive on the computer, when he first mentioned it, I would have told him that it was partitioned into two drives, so he didn’t give it a second thought. I guess he didn’t know me as well as he thought.
Anyway, after that, he never said anything about the operators using the computer for other uses than monitoring the precipitator, which was always a problem before. George never mentioned the hard drive again. I don’t remember now if I later changed the volume name on the drive. It seemed like not long after the computers were upgraded from the IBM AT to something like a XT 286.
Oh. I had another joke I played on George. The other one lasted for years, and he never figured it. I will write about that one later. That one wasn’t so much of a joke as it was out of necessity. I won’t say anymore about it now. You’ll have to wait at least another week or two (See the post Power Plant Paradox of Front to Back and Back to Front).
Power Plant Genius of Larry Riley
Favorites Post #21
Originally posted February 25, 2012. I added Larry’s Picture at the end:
When I first began working at the power plant (in 1979), one of the people I spent a good deal of time with was Larry Riley. I was 18 and knew very little about tools, equipment, power plants and how to speak in the Power Plant language. I quickly found out that in those early days, when the plant was still under construction, a lot of people turned to Larry Riley when they were faced with an obstacle and didn’t know how to approach it.
Larry Riley was a 24 year old genius. I was amazed by his vast knowledge of seemingly disparate areas of expertise. When he was asked to do something, I never heard him say that he didn’t know how. He just went and did it. So, after I asked Larry how old he was, I asked him how long he had been at the plant. He hadn’t been there very long, but he had worked in the construction department before transferring to the power plant.
Larry Riley already at the age of 24 had a beat up hard hat full of hard hat stickers. One indicating that he was a certified industrial truck driver. I think he had about 5 safety stickers and various other hard hat stickers. He was a thin clean cut dark haired young man with a moustache that sort of reminded me of the Marlboro Man’s moustache. He walked like he had a heavy burden on his back and he was rarely seen without a cigarette in his mouth.
Yep. That’s the Marlboro Man
I worked with Larry off and on throughout my years as a summer help and during that time Larry taught me the following things (to name a few): How to drive a tractor. How to mend a fence. How to bleed the air out of a diesel engine’s fuel line (which is more important than you would think). How to operate a brush hog (a large mower on the back of a tractor). How to free a brush hog from a chain link fence after you get one of the bat wings stuck in one. Tie rebar, and pour concrete and operate a Backhoe.
I remember asking Larry why a backhoe was called a backhoe. I think Sonny Karcher was in the truck at the time. You would have thought I had asked what year the War of 1812 was fought! I’m sure you are all chuckling while reading this (especially all the power plant men). But for those of you who are as green as I was, I’ll tell you. A Backhoe is called a Backhoe because the Hoe is on the Back. Gee. Who would have thought?
-
Here is a picture of a backhoe
Later when I was a full time employee and had worked my way from being a Janitor to being on the Labor Crew, Larry Riley became my foreman. At that point on occasion I would call him “Dad”. He would usually disown me and deny that he had anything to do with it. On occasion when he would own up to being my dad, he would admit that when I was real little I was dropped on my head and that’s why I acted so odd (though, I don’t know to what behavior he was referring).
There was this other guy at the plant the first summer I was there that had the unique title of “Mill Wright”. His name was Gary Michelson. He evidently had gone to school, taken some tests and been certified as a Mill Wright and this probably brought him a bigger paycheck than the other regular workers as well as a much bigger ego.
Gary would spend days at a time at a band saw cutting out metal wedges at different angles so that he would have them all in his pristine tool box. I worked with him a few times during my first summer as a summer help. I will probably talk more about Gary in a later post, but just to put it plainly… I could tell right away that he wasn’t a real “power plant man”.
The rest of the power plant men I’m sure would agree with me. I wouldn’t have traded Larry Riley for ten Gary Michelsons unless I was trying to help some engineers change a light bulb (actually. I have met some good engineers along the way. Some of them very good. But they were not the norm. At least not those assigned to power plants).
I have mentioned some different things that Larry had taught me and if you remember, he was the person that I worked with on my second day at the plant when Sonny Karcher and Larry had taken me to the coalyard to fix the check valve (in my post about Sonny Karcher “In Memory of Sonny Karcher – Power Plant Man“). There will always be one day that first comes to my mind when I think about Larry. This is what happened:
I drove a truck down to the Picnic area on the far side of the lake from the plant. Jim Heflin drove a Backhoe down there. I believe he was going to dig up some tree stumps that had been left over after the “engineers” in Oklahoma City had decided where to put all the trees in the area.
What the engineers in Oklahoma City did was this: They cut down all of the trees that were in the picnic area and planted new trees. Some of them not more than 15 or 20 feet away from a tree that had been there for 30 years and was a good size. So, there were a lot of stumps left over from the big hearty trees that had been cut down that needed to be removed so that the sickly little twigs that were planted there could prosper and grow without feeling inadequate growing next to a full grown he-man tree.
Anyway. I had climbed out of the truck and was making my way around the picnic area picking up trash and putting it in a plastic bag using a handy dandy homemade trash stabbing stick. As Jim was making his way across the “lawn” (I use the word “lawn” loosely, since the area was still fairly new and was not quite finished) when he hit a wet spot. The Backhoe was stuck in the mud.
There wasn’t much I could do but watch as Jim used the hoe to try to drag himself out. He rocked the backhoe back and forth. Use the stabilizers to pick up the backhoe while trying to use the scoop to pull it forward. I would say he worked at it for about ten minutes (even though it seemed more like half an hour). Eventually it was time for us to head back to the plant to go to break.
Back at the plant, Jim told Larry about his predicament and asked him if he would help him get the backhoe out of the mud. Larry said he would come along and see what he could do. At this point, I was thinking that he would jump in the Wench Truck and go down there and just pull him out. Instead we just climbed in the pickup truck and headed back to the park (notice how it went from being a picnic area to a park in only three paragraphs?).
When we arrived, Larry climbed into the Backhoe after making his way across the vast mud pit that Jim had created while trying to free himself before. He fired up the Backhoe…. cigarette in mouth… then the most fascinating thing happened… using both feet to work the pedals, and one hand working the controls in the front and the other hand working the levers in the back, Larry picked up the backhoe using the scoop and the hoe and stabilizers and cigarette all simultaneously, he walked the backhoe sideways right out of the mud pit and onto dry land just as if it was a crab walking sideways. I would say it took no longer than three minutes from the time he started working the controls. Jim just looked at me in amazement. Patted me on the back, shook his head and said, “And that’s how it’s done.”
This is the best picture I could find of Jim Heflin
Now that I’m on the subject of Larry Riley on a backhoe, let me tell you another one. I have seen Larry digging a ditch so that we could run some pipe for irrigation. Now picture this. The bucket on the backhoe is digging a hole in the hard red clay of Oklahoma, and Larry suddenly stops and says….. “I think I felt something”. What? (I think) Of course you did, you are operating this machine that has the power to dig a big hole in the ground in one scoop like it was nothing and Larry said he felt something?
He climbed off of the backhoe, jumped down into the ditch he was creating, kicked some clods of dirt around and lo and behold, he had just scraped clean a buried cable. He hadn’t broken it. He had come down on it with the bucket and had somehow “felt” this cable buried under all that dirt. I wonder what it felt like that told him he had encountered something that wasn’t just dirt. Maybe the electromagnet forces from the electricity in the cable caused the backhoe to be slightly magnetized and it tugged on his key chain. I think the entire labor crew just went down on one knee before his greatness for a moment of silence – all right, so we didn’t really. But we were somewhat impressed.
The one thing that makes Larry a True Power Plant Man with all the rest is that he performed acts of greatness like what I described above with complete humility. I never saw a look of arrogance in Larry’s face. He never spoke down to you and he never bragged about anything. To this day, I still picture Larry Riley working at the power plant working feats of magic that would amaze the rest of us as he thinks that he’s just doing another day’s work. That’s the way it is with True Power Plant Men.
Since I first created this post two years ago, I have found a picture of Larry Riley taken many years after this story:
Larry Riley 20 years after I first met him. He has a much newer hardhat in this picture
Since I first posted this story about Larry, he has passed away. I described the day of his passing in the post: “Power Plant Saints Go Marching In“
Toby O’Brien and Doing the Impossible
Favorites Post #18
Originally posted May 23, 2014:
There were three times when I was an electrician at a coal-fired Power Plant in North Central Oklahoma when, according to others, I had done something that they labelled “impossible”. One of those times began when a Plant Engineer Toby O’Brien came to me and asked me if I could find a way to connect to the Prime Computer down at Corporate Headquarters so that he could edit some Engineering drawings he had worked on when he was working at Oklahoma City. That in itself wasn’t what was impossible. That came later, but it pertained to a similar subject.
Somewhere in Corporate Headquarters stashed away in an isolated room was a Prime Computer just waiting for Toby.
Prime Computer
Toby knew that I had an account on the Honeywell Mainframe computer downtown, since I was always getting myself in trouble playing around on it. Since I could connect to that, he wondered if it would be possible to connect to the Prime Computer where his Medusa CAD drawings were kept. He gave me some information about how he used to log into it when he was working downtown…. before he was banished to the Power Plant Palace 70 miles north out in the middle of the country.
Toby had a CAD tablet and a disk to install the driver on a computer. This would allow him to work on his CAD drawings. For those of you who don’t remember, or have never seen such a thing. It is like a very fancy mouse…. or should I say, Mouse Pad. Since you used a stylus to draw and point and click on a large pad called a tablet. Not anything like the little tablets we have today.
CAD Drawing Tablet
At the time, the only connection we had to the Honeywell Mainframe from the power plant was through a router called a Memotec. The bandwidth was a whopping 28,000 baud. A Baud is like bytes per second, only it is measured over an audio line as an audio signal. Like the sound that a Fax machine makes when it first connects. Toby had talked to some guys down at IT and they had a copy of the same Honeywell emulator called “GLink” we were using at the plant, only it would connect at a super whopping 56,000 baud. Twice as fast! They wanted someone to “Beta Test” it. They knew I liked doing that sort of stuff, so they were willing to give us a copy to try out.
This is GLink today. Back then it was for Windows 3.1
Toby and I decided that the best place to try out our “Beta Testing” was in the Chemistry Lab. The main reason was that it had one of the newer 386 desktop computers and it was in a room right next to the data closet where the Memotec was talking to the mainframe downtown. So, if I had to run in there real quick and spit in the back and “whomp it a good ‘un”, I wouldn’t have too go far. That was a trick I learned from watching “No Time for Sergeants” with Andy Griffith. Here is the lesson:
If you have trouble viewing the video from the picture above, this this link: “No Time For Sergeants Radio Operator“.
To make the rest of this part of the story a little shorter, I’ll just summarize it to say that by logging into the Honeywell Mainframe using my account, I was then able to connect to the Prime Computer using Toby’s account and he was able to edit his CAD drawings from the Chemistry Lab at the Power Plant 70 miles away from Corporate Headquarters. I know that doesn’t sound like much, but in those days, this was “new technology” for us Power Plant guys anyway.
Before I continue with the “impossible” task, I need to explain a little about how electricians kept the Electrical Blueprints up-to-date at a Power Plant. This was a task that I was given when Tom Gibson was the Electrical Supervisor. I was supposed to take all the blueprints that had been revised because of some change that had happened at the plant, and make sure they were properly updated. Then I had to go through a process to make sure they were permanently updated, not only on the three copies that we had at our plant, but also with the “System of Record” set of blueprints at Corporate Headquarters.
So, let me tell you the process, and I’m sure you will be able to relate this task to something you encounter in your job today. Even if it is preparing the Salads at a Sirloin Stockade before opening time.
The first step happens when someone in the electric shop has to rewire some piece of equipment or something because the equipment was moved, removed, upgraded to something else, or someone thought it would work better if we did it a different way. Then whoever made the change to the electric wiring would go to the prints that were kept in the electric shop and update them so that the new wiring job was reflected in the Blueprints.
This is important because if someone a week later had to go work on this equipment, they would need to be able to see how the equipment is now wired. If they were working off of an old print, then they might blow something up, or injure or even kill someone…. most likely themselves, if it ever came down to it.
The other two copies of prints also needed to be updated. One was in the Instrument and Controls shop, and the most important copy was in the “Print Room” right next to Tom Gibson’s office.
The second step was to send off a request to Corporate Headquarters in Oklahoma City for a copy of all the blueprints that were changed so that the change could be made on the copy and sent back to Oklahoma City.
The third step is when a fresh copy of the blueprints arrived at the plant from Oklahoma City a few weeks later. These were updated with the changes and sent back to Oklahoma City.
The fourth step is when the blueprints are reviewed by an engineer downtown and the changes are made permanently by a drafter downtown.
Step five: Then three copies of the permanently changed prints were sent back to plant where they replaced the three marked up copies.
This process generally took two to three months given that the drafter downtown had to take the Original drawing, scan it in the computer, make changes to it, and then save it, and send it to the printer to be printed.
Toby and I had “petitioned” our plant management to buy us a copy of AutoCAD so that we could make our own revisions right at the plant, and send the changes directly to Oklahoma City, all complete and ready to go. The only problem with this was that AutoCAD software did not come cheap. It was several thousand dollars for just one copy.
Oh. Here is a picture of Toby:
Toby O’Brien when he was young
Even though this was before the World Wide Web, I knew where I could get a pirated copy of AutoCAD, but since neither Toby or I considered ourselves criminals, we never really considered that a viable alternative. Tom Gibson was pitching for us to have a copy, but it was figured that if we had a copy, the company would have to buy a copy for all six main power plants, and they weren’t willing to dish out that much money.
Somewhere along the line, after Tom Gibson had kept pushing for the importance of having up-to-date Plant Electric Blueprints in a timely fashion, a task force was formed to address a faster way to make print revisions. Because Toby and I (and Terry Blevins) had been pushing this at our plant, Tom asked Toby and I (actually, that should be “Toby and me”, but “Toby and I” makes me sound smarter than I am) to be on the Task Force with him.
So, one morning after arriving at the plant, we climbed into a company car and made the drive to Oklahoma City to the Corporate Headquarters. When we arrived, we sat in a big conference room with members from the different power plants, and a number of engineers from downtown. I was pretty excited that something was finally going to be done.
I don’t remember the name of the engineer that was the leader of the task force, I only remember that I had worked with him once or twice through the years on some small projects. When the meeting began, I expected that we would have some kind of brainstorming activity. I was all ready for it, since I had all sorts of ideas about how we could just edit the prints directly from the plant on the Prime Computer where the prints were stored, just like Toby had done.
When the meeting began there was no brainstorming session. There wasn’t even a “What do you guys think about how this can be done?” No. The engineer instead went on to explain his solution to the problem. I was a little disappointed. Mainly because I was all fired up about being asked to be on a task force in Oklahoma City to work on…. well…. anything…. to tell you the truth. And here we were listening to a conclusion. — Sound familiar? I knew it would.
This engineer had it all figured out. Here was his solution:
Step 1: A request was sent by company mail to downtown (same at the old second step) for some blueprints that need to be updated.
Step 2: The prints are downloaded onto a floppy disk (3.5 inch High Density – which meant, 1.44 Megabyte disks).
Step 3: The disks were mailed through company mail back to the Power Plant.
Step 4: The Power Plant receives the disks and loads them onto their computer at the plant and they edit the blueprint using a pared down CAD program called “RedLine” (somewhat cheaper than AutoCAD).
Step 5: The print revision is saved to the disk and the disk is mailed back to Corporate Headquarters using the Company Mail.
Step 6: The print is reviewed by the engineers for accuracy and is loaded into the computer as the system of record.
Ok…. this sounded just like the previous method only we were using a “RedLine” program to edit the changes instead of using Red, Green and Gray pencils.
It was evident that the engineer in charge of the meeting was expecting us to all accept this solution and that the task force no longer had to meet anymore, and we could all go home and not ever return to consider this problem again. — Well, this was when I said the “Impossible” (oh. I should italicize that like this: “Impossible!”).
I raised my hand as if I was in a classroom. The guy knowing me to be a regular troublemaker asked me what I wanted. I said, “Why mail the files? Why not just put them in a folder and have the person at the plant go there and pick them up?” — In today’s world the idea of a drop-box is about as easy to understand as “Google it”. Back then… I guess not. Especially for some engineers who had already decided on a solution.
So, the engineer responded, “Because that can’t be done.” I said, “Why not?” He said, “It’s impossible. Someone in a power plant can’t just go into a computer at Corporate Headquarters and access a file.”
Well, that did it….. I told him that we were able to edit CAD drawings on the Prime computer from the power plant. He said, “No you didn’t. That’s impossible!” I looked over at Toby who was sitting next to me with a big grin on his face. So I said, “Who is the IT guy in the room? He can tell you that you can get a file from the mainframe from the power plant.”
The engineer replied that he didn’t invite any IT people, because there wasn’t any reason. Everyone knows that you can’t copy files on a Corporate computer from a power plant. So, I said, “Invite someone from the IT department to the next meeting. I’m sure he will agree with me that this can be done. — Shortly after that, the meeting was adjourned (but at least I had managed to convince the team we needed a second meeting – which meant a second trip to OKC with my good friend Toby).
You should have heard me rant and rave all the way back to the power plant that afternoon. How could he possibly be so naive to make definite statements about something and basically call me a liar when I said that we had already done it. I’m sure Tom Gibson was glad when we arrived back at the plant and he was able to get out of the company car and into the silence of his own car for his drive back to Stillwater. Toby on the other hand carpooled with me, so he had to hear me rant and rave to Scott Hubbard all the way back to Stillwater that day.
Needless to say, we had another Print Revision Task Force meeting a few weeks later. Tom, Toby and I drove back to Oklahoma City. I couldn’t wait to see what was going to happen.
The meeting began with the engineer in charge of the task force saying, “The first thing we are going to address is Kevin Breazile’s statement about sending files to the power plant. We have invited someone from IT to answer this question.” Then he turned to a guy sitting at the table. I don’t remember his name either, only that I had worked with him also through the years (oh yes I do. It was Mike Russell).
The engineer turned to the IT guy and said (using a sing-song tone that indicated that I belonged in a mental institution or maybe kindergarten), “Kevin seems to think that he can somehow get on his computer at the power plant and access a folder on a server here at Corporate Headquarters and download a file.” He stopped and with a big smirk on his face looked at the IT guy. Mike just sat there for a moment looking at him.
The engineer just stood there with an evil grin on his face waiting… Mike said, “So? What do you want to know?” The engineer said, “Well. Is that even possible?” Mike replied, “Of course! It’s actually easier for him to do that than it is for someone on the 3rd floor of this building to access the mainframe on the fourth floor.”
The engineer’s jaw dropped and he eked out a meager little “what?” Mike asked if that was all. When he was assured that this was the only question, he stood up and walked out the door. As he was leaving he turned a side glance toward me and winked at me. I was grinning ear-to-ear. I could tell, I wasn’t the only one that had a beef with this particular engineer.
So, you would have thought that it would have been a quieter ride back to the plant that day, but leave it to me…. I kept on going on about how that guy was so sure of himself that he didn’t even bother to ask the IT guy before the meeting began just to check his own erroneous assumptions. Geez! That was the most surprising part of the day. If he had only asked him before the meeting, he wouldn’t have made a fool out of himself with his snide comments just before he was put in his place.
So, Toby and I proved that doing the impossible isn’t all that impossible when what someone thinks is impossible really isn’t so. This stemmed from a lesson my dad taught me growing up when he told me, “Don’t ever say “can’t”. There is always a way.”
UPDATE: Toby died January 4, 2020, I wrote a post when I found out: Reference Letter for Toby O’Brien – Power Plant Engineer
Comments from the original post:
Power Plant Genius of Larry Riley
Originally posted February 25, 2012. I added Larry’s Picture at the end:
When I first began working at the power plant (in 1979), one of the people I spent a good deal of time with was Larry Riley. I was 18 and knew very little about tools, equipment, power plants and how to speak in the Power Plant language. I quickly found out that in those early days, when the plant was still under construction, a lot of people turned to Larry Riley when they were faced with an obstacle and didn’t know how to approach it.
Larry Riley was a 24 year old genius. I was amazed by his vast knowledge of seemingly disparate areas of expertise. When he was asked to do something, I never heard him say that he didn’t know how. He just went and did it. So, after I asked Larry how old he was, I asked him how long he had been at the plant. He hadn’t been there very long, but he had worked in the construction department before transferring to the power plant.
Larry Riley already at the age of 24 had a beat up hard hat full of hard hat stickers. One indicating that he was a certified industrial truck driver. I think he had about 5 safety stickers and various other hard hat stickers. He was a thin clean cut dark haired young man with a moustache that sort of reminded me of the Marlboro Man’s moustache. He walked like he had a heavy burden on his back and he was rarely seen without a cigarette in his mouth.
Yep. That’s the Marlboro Man
I worked with Larry off and on throughout my years as a summer help and during that time Larry taught me the following things (to name a few): How to drive a tractor. How to mend a fence. How to bleed the air out of a diesel engine’s fuel line (which is more important than you would think). How to operate a brush hog (a large mower on the back of a tractor). How to free a brush hog from a chain link fence after you get one of the bat wings stuck in one. Tie rebar, and pour concrete and operate a Backhoe.
I remember asking Larry why a backhoe was called a backhoe. I think Sonny Karcher was in the truck at the time. You would have thought I had asked what year the War of 1812 was fought! I’m sure you are all chuckling while reading this (especially all the power plant men). But for those of you who are as green as I was, I’ll tell you. A Backhoe is called a Backhoe because the Hoe is on the Back. Gee. Who would have thought?
-
Here is a picture of a backhoe
Later when I was a full time employee and had worked my way from being a Janitor to being on the Labor Crew, Larry Riley became my foreman. At that point on occassion I would call him “Dad”. He would usually disown me and deny that he had anything to do with it. On occassion when he would own up to being my dad, he would admit that when I was real little I was dropped on my head and that’s why I acted so odd (though, I don’t know to what behavior he was referring).
There was this other guy at the plant the first summer I was there that had the unique title of “Mill Wright”. His name was Gary Michelson. He evidently had gone to school, taken some tests and been certified as a Mill Wright and this probably brought him a bigger paycheck than the other regular workers as well as a much bigger ego.
Gary would spend days at a time at a band saw cutting out metal wedges at different angles so that he would have them all in his pristine tool box. I worked with him a few times during my first summer as a summer help. I will probably talk more about Gary in a later post, but just to put it plainly… I could tell right away that he wasn’t a real “power plant man”.
The rest of the power plant men I’m sure would agree with me. I wouldn’t have traded Larry Riley for ten Gary Michelsons unless I was trying to help some engineers change a light bulb (actually. I have met some good engineers along the way. Some of them very good. But they were not the norm. At least not those assigned to power plants).
I have mentioned some different things that Larry had taught me and if you remember, he was the person that I worked with on my second day at the plant when Sonny Karcher and Larry had taken me to the coalyard to fix the check valve (in my post about Sonny Karcher “In Memory of Sonny Karcher – Power Plant Man“). There will always be one day that first comes to my mind when I think about Larry. This is what happened:
I drove a truck down to the Picnic area on the far side of the lake from the plant. Jim Heflin drove a Backhoe down there. I believe he was going to dig up some tree stumps that had been left over after the “engineers” in Oklahoma City had decided where to put all the trees in the area.
What the engineers in Oklahoma City did was this: They cut down all of the trees that were in the picnic area and planted new trees. Some of them not more than 15 or 20 feet away from a tree that had been there for 30 years and was a good size. So, there were a lot of stumps left over from the big hearty trees that had been cut down that needed to be removed so that the sickly little twigs that were planted there could prosper and grow without feeling inadequate growing next to a full grown he-man tree.
Anyway. I had climbed out of the truck and was making my way around the picnic area picking up trash and putting it in a plastic bag using a handy dandy homemade trash stabbing stick. As Jim was making his way across the “lawn” (I use the word “lawn” loosely, since the area was still fairly new and was not quite finished) when he hit a wet spot. The Backhoe was stuck in the mud.
There wasn’t much I could do but watch as Jim used the hoe to try to drag himself out. He rocked the backhoe back and forth. Use the stabilizers to pick up the backhoe while trying to use the scoop to pull it forward. I would say he worked at it for about ten minutes (even though it seemed more like half an hour). Eventually it was time for us to head back to the plant to go to break.
Back at the plant, Jim told Larry about his predicament and asked him if he would help him get the backhoe out of the mud. Larry said he would come along and see what he could do. At this point, I was thinking that he would jump in the Wench Truck and go down there and just pull him out. Instead we just climbed in the pickup truck and headed back to the park (notice how it went from being a picnic area to a park in only three paragraphs?).
When we arrived, Larry climbed into the Backhoe after making his way across the vast mud pit that Jim had created while trying to free himself before. He fired up the Backhoe…. cigarette in mouth… then the most fascinating thing happened… using both feet to work the pedals, and one hand working the controls in the front and the other hand working the levers in the back, Larry picked up the backhoe using the scoop and the hoe and stabilizers and cigarette all simultaneously, he walked the backhoe sideways right out of the mud pit and onto dry land just as if it was a crab walking sideways. I would say it took no longer than three minutes from the time he started working the controls. Jim just looked at me in amazement. Patted me on the back, shook his head and said, “And that’s how it’s done.”
This is the best picture I could find of Jim Heflin
Now that I’m on the subject of Larry Riley on a backhoe, let me tell you another one. I have seen Larry digging a ditch so that we could run some pipe for irrigation. Now picture this. The bucket on the backhoe is digging a hole in the hard red clay of Oklahoma, and Larry suddenly stops and says….. “I think I felt something”. What? (I think) Of course you did, you are operating this machine that has the power to dig a big hole in the ground in one scoop like it was nothing and Larry said he felt something?
He climbed off of the backhoe, jumped down into the ditch he was creating, kicked some clods of dirt around and lo and behold, he had just scraped clean a buried cable. He hadn’t broken it. He had come down on it with the bucket and had somehow “felt” this cable buried under all that dirt. I wonder what it felt like that told him he had encountered something that wasn’t just dirt. Maybe the electromagnet forces from the electricity in the cable caused the backhoe to be slightly magnetized and it tugged on his key chain. I think the entire labor crew just went down on one knee before his greatness for a moment of silence – all right, so we didn’t really. But we were somewhat impressed.
The one thing that makes Larry a True Power Plant Man with all the rest is that he performed acts of greatness like what I described above with complete humility. I never saw a look of arrogance in Larry’s face. He never spoke down to you and he never bragged about anything. To this day, I still picture Larry Riley working at the power plant working feats of magic that would amaze the rest of us as he thinks that he’s just doing another day’s work. That’s the way it is with True Power Plant Men.
Since I first created this post two years ago, I have found a picture of Larry Riley taken many years after this story:
Larry Riley 20 years after I first met him. He has a much newer hardhat in this picture
Since I first posted this story about Larry, he has passed away. I described the day of his passing in the post: “Power Plant Saints Go Marching In“
When Power Plant Durability and Automation Goes Too Far
Everyone expects when they enter an elevator and push a button for the 3rd floor that when the doors open they will find themselves on the third floor. It doesn’t occur to most people what actually has to happen behind the scenes for the elevator to go through the motions of carrying someone up three stories. In most cases you want an automated system that requires as little interaction as possible.
I have found while working in the Coal-fired Power Plant in North Central Oklahoma that some systems are better off with a little less than perfect automation. We might think about that as we move into a new era of automated cars, robot soldiers and automatic government shutdowns. Let me give you a for instance.
The coal trains that brought the coal from Wyoming all the way down to the plant would enter a building called “The Dumper.” Even though this sounds like a less savory place to park your locomotive, it wasn’t called a Dumper because it was a dump. It was called a Dumper because it “Dumped.” Here is a picture of a dumper:
A rotary dumper much like the one that was at our Power Plant
The coal train would pull into this room one car at a time. I talked about the dumper in an earlier post entitled “Lifecycle of a Power Plant Lump of coal“. As each car is pulled into this building by a large clamp called the “Positioner” (How is that for a name? It is amazing how when finding names for this particular equipment they decided to go with the “practical” words. The Positioner positions the coal cars precisely in the right position so that after the car clamps come down on the car, it can be rotated upside down “Dumping” the coal into the hoppers below. No fancy names like other parts of the power Plant like the “Tripper Gallery” or the “Generator Bathtub” here.
A typical coal train has 110 cars full of coal when it enters the dumper. In the picture of the dumper above if you look in the upper left corner you will see some windows. This is the Dumper Control Room. This is where someone sits as each car pulls through the dumper and dumps the coal.
Not long after the plant was up and running the entire operation of the dumper was automated. That meant that once put into motion, the dumper and the controls would begin dumping cars and continue operating automatically until the last car was through the dumper.
Let me try to remember the sequence. I know I’ll leave something out because there are a number of steps and it has been a while since I have been so fortunate as to work on the dumper during a malfunction… But here goes…
I remember that the first coal car on the train had to positioned without the positioner because… well….. the car directly in front of the first car is, of course, the locomotive. Usually a Burlington Northern Santa Fe Engine.
A picture from Shutterstock of a locomotive pulling a coal train
Before I explain the process, let me show you a picture of the Positioner. This the machine that pulls the train forward:
The piece of equipment with the large wheels is the positioner It can pull a coal train full of coal forward to precisely the proper position
The automation begins after the first or second car is dumped. I’ll start with the second car just finishing the process as it rolls back up right after dumping the coal… The car clamps go up.
- The rear holding arm (that holds the car in place from the entrance side of the dumper) lifts up out of the way.
- The Positioner begins pulling the entire train forward.
- Electric eyes on both end of the dumper detect when the next car has entered the dumper.
- The Positioner adjusts the position of the coal car to the exact position (within an inch or two) by backing up and pulling forward a couple of times.
- The Holding arm on the back end comes down on the couplings between the two train cars one back from the car that is going to be dumped.
- The four car clamps come down on the train car at the same time that the dumper begins rotating.
- The Positioner clamp lifts off of the train car couplings.
- Water Sprayers come on that are attached to the top of the dumper so that it wets the coal in order to act as a dust suppression.
- The Positioner travels back to the car clamp between the car that was just emptied before and the car in front of it.
- As the train car rotates to the desired angle. (I think it’s about 145 degrees), it begins slowing down.
- When the car has been rotated as far as desired it comes to a stop.
- The Dumper pauses for a few seconds as all the coal is dumped from the coal car.
- The Positioner moves back and forth until it is in just the right position for the positioner arm to lower onto the couplings between the cars.
- The Sprayers turn off.
- The Dumper begins returning to an upright position.
- The Positioner arm lowers down onto the clamps between the coal cars.
- Once the car is upright the dumper stops rotating.
- The 4 car clamps go up.
- The Holding arm goes up. And the process is repeated.
This is a beautiful process when it works correctly. Before I tell you about the times it doesn’t work correctly, let me tell you about how this process was a little…uh… too automated…
So. The way this worked originally, was that once the automated process was put into operation after the second car had been dumped, all the dumper control room operator had to do was sit there and look out the window at the coal cars being dumped. They may have had some paperwork they were supposed to be doing, like writing down the car numbers as they pulled through the dumper. It seems that paperwork was pretty important back then.
Each car would pull through the dumper… The coal would be dumped. The next car would be pulled in… etc.
Well. Trains come from Wyoming at any time of the day. Train operators were paid pretty well, and the locomotive engineers would come and sit in the control room while the train was being dumped. Often (more often than not it seemed) the trains would pull into the dumper in the middle of the night. Coalyard operators were on duty 24 by 7.
So, imagine this…. Imagine Walt Oswalt… a feisty sandy haired Irishman at the dumper controls around 3 in the morning watching 110 cars pull through the dumper. Dumping coal…. One after the other. I think the time it took to go from dumping one car to the next was about 2 1/2 minutes. So it took about 3 1/2 hours to dump one train (I may be way off on the time… Maybe one of the operators would like to leave a comment below with the exact time).
This meant that the dumper operator had to sit there and watch the coal cars being slowly pulled through the dumper for about 3 hours. Often in the middle of the night.
For anyone who is older than 30 years, you will remember that the last car on a train was called a Caboose. The locomotive engineers called it a “Weight Car”. This made me think that it was heavy. I don’t know. It didn’t look all that heavy to me… You decide for yourself:
A Caboose
Back in those days, there was a caboose on the back of every train. A person used to sit in there while the train was going down the tracks. I think it was in case the back part of the train accidentally became disconnected from the front of the train, someone would be back there to notice. That’s my guess. Anyway. Later on, a sensor was placed on the last car instead of a caboose. That’s why you don’t see them today. Or maybe it was because of something that happened one night…
You see… it isn’t easy for Walt Oswalt (I don’t mean to imply that it was Walt that was there that night.. well… it sounds like I’m implying that doesn’t it…. I use Walt when telling this story because he wouldn’t mind. I really don’t remember who it was) to keep his eyes open and attentive for 3 straight hours. Anyway… One night while the coal cars were going through the dumper automatically being dumped one by one… there was a point when the sprayers stopped spraying and the 4 car clamps rose, and there there was a moment of pause, if someone had been there to listen very carefully, they might have heard a faint snoring sound coming from the dumper control room.
That is all fine and dandy until the final car rolled into the dumper. You see… One night…. while all the creatures were sleeping (even a mouse)… the car clamps came down on the caboose. Normally the car clamps had to be raised to a higher position to keep them from tearing the top section off of the caboose.
If it had been Walt… He woke when he heard the crunching sound of the top of the caboose just in time to see the caboose as it swung upside down. He was a little too late hitting the emergency stop button. The caboose rolled over. Paused for a moment as the person manning the caboose came to a rest on the ceiling inside… then rolled back upright all dripping wet from the sprayer that had meant to keep down the dust.
As the car clamps came up… a man darted out the back of the caboose. He ran out of the dumper…. knelt down… kissed the ground… and decided from that moment on that he was going to start going back to church every Sunday. Ok. I exaggerate a little. He really limped out of the dumper.
Needless to say. A decision had to be made. It was decided that there can be too much automation at times. The relay logic was adjusted so that at the critical point where the dumper decides to dump a coal car, it had to pause and wait until the control room operator toggled the “Dump” switch on the control panel. This meant that the operator had to actively decide to dump each car.
As a software programmer…. I would have come up with another solution… such as a caboose detector…. But given the power that was being exerted when each car was being dumped it was probably a good idea that you guaranteed that the dumper control room operator actually had his eyeballs pointed toward the car being dumped instead of rolled back in his head.
I leave you with that thought as I go to another story. I will wait until another time to talk about all the times I was called out at night when the dumper had failed to function.
This is a short story of durability…
I walked in the electric shop one day as an electrician trainee in 1984 to find that Andy Tubbs had taken an old drill and hooked it up to the 480 volt power source that we used to test motors. Ok. This was an odd site. We had a three phase switch on the wall with a fairly large cable attached with three large clips so we could hook them up to motors that we had overhauled to test the amperage that they pulled to make sure they were within the specified amount according to their nameplate.
I hesitated a moment, but I couldn’t resist…. I had to ask, “Andy…. Why have you hooked up that old drill to 480? (it was a 120 volt drill). He replied matter-of-factly (Factly? Can I really say that in public?), “I am going to burn up this old drill from the Osage Plant (See “Pioneers of Power Plant Fame Finally Find Peace” for more information about Osage Plant) so that I can turn it in for a new one.
Ok. I figured there must be a policy somewhere that said that if you turned in a burned up tool they would give you a new one. I knew that Bud Schoonover down at the toolroom was always particular about how he passed out new tools (I have experienced the same thing at my new job when trying to obtain a new security cable for my laptop).
Anyway. Andy turned the 480 volts on and powered up the drill. The drill began whining as it whirled wildly. Andy stood there holding up the drill as it ran in turbo mode for about five minutes. The drill performed like a champ.
Old Power Drill
After showing no signs of burning itself up running on 480 volts instead of 120 volts, Andy let off of the trigger and set it back on the workbench. He said, “This is one tough drill! I think I’ll keep it.” Sure. It looked like something from the 1950’s (and it probably was). But, as Andy said, it was one tough drill. On that day, because of the extra Durability of that old Pioneer Power Plant Drill, Andy was robbed of a new variable speed, reversible drill that he was so craving.

Comments from original post:
Great stories!
Coal trains today have engines at the rear of the train. I hope we never try to dump one of them!
It takes about 7 hrs to dump 150 car train
Wasn’t Walt but a certain marine we won’t mention. They dumped the last car & forgot to put the car clamps in the up maximum position. They give the go ahead for the train to pull the caboose through! Instant convertible caboose! Now there are break away clamps on the north side. And there are locomotives on the rear of the train because the trains are made up of 150 cars .
Like you, I can think of several ways to automate the process without dumping the caboose but I think the operator pushing the button may be the best. Automation can get out of hand.
An engineer used to remind us: “A machine always does what you tell it to…whether you want it to, or not.”
IF the union or the lawyers require a duty operator on an automated process, I’m all for giving him a button to push and attaching some responsibility. All automation designs are approved by Murphy…Wow! Thanks for the update Bruce!
Bohn’s Boner and the Power Plant Precipitator Computer
Originally posted on January 11, 2014:
Up front, I would like to clarify the title so that those who are quickly perusing articles looking for something salacious won’t have to read too far before they realize this isn’t what they are seeking. The word “Boner” in this headline refers to a “joke” played on a Plant Engineer by the name of George Bohn at the coal-fired Power Plant in North Central Oklahoma. When I was a boy we had a joke book called the “Omnibus Book of Boners”. Most of my life I never thought about the word “Boner” as having another meaning. Which, after this joke was played might have explained the expression on George’s face.
Joke Book
In an earlier Post “Power Plant Humor and Joking With Gene Day” I explained that when playing a Power Plant joke, the longer it takes to play a simple joke, the better the effect. I think the reason for this is that when the person realizes that a joke has been played on them by a fellow Power Plant Man and even though it was simple, the person went through the effort over a long period of time, just to make you smile for a moment. Then you know that this person must truly be a good friend. Who else would waste countless hours on someone over days, weeks, or even months, just to make someone smile once?
Well…. Bohn’s Boner lasted for over six months! Yeah. Six months, at least.
I saw the opportunity arise one day after we had received a new hard drive for precipitator computer for Unit 2. We had the computers for a couple of years after we went to digital controls in the precipitator before the hard drive crashed. This happened to be a project that George Bohn had managed. He was the project manager and had overseen the installation of the precipitator controls, which included the two precipitator computers in the control room. One for each unit. They sat around behind the big control panel that you see when you watch an older movie about a Power Plant Control Room, like the China Syndrome.
I love this picture!
Anyway, each of the computers had 30 Megabyte hard drives. Yeah. You heard that right! 30 Megabytes. That’s not a typo. Not Gigabytes… nope. Megabytes. Just this morning at Dell, I received an e-mail with a file attached that was over 30 Megabytes in size (Thanks Norma). I’m talking about an IBM AT computer:
IBM PC
Well, the Unit 2 precipitator computer was used to monitor all of the 84 control cabinets in the Precipitator control room. It indicated how much voltage and amperage were on each cabinet, as well as the spark rate, and the setting on each cabinet. It was really a great step up. I’m sure today you can probably do that from your phone while you are sitting in a movie theater just before they tell you to silence your “Cell Phone Now” and stop texting your neighbor. Back then, it was amazing.
All the operator had to do was go over to the computer, pull up the screen (this was before Windows, but the program was running by default), and type the keyboard command to tell it to print and “voila”, it would print out all that information. The operator could look at it to see if there was a problem, and if not, he just saved it with all the other reports he was supposed to create during his shift.
Believe it or not. Before this time, the operator actually walked up to all of the 84 cabinets on each unit and looking at meters on the cabinet wrote down the voltage and amperage of each cabinet on a form. You can imagine how much happier they were to be able to print it all out in the control room. Hours and hours saved each week.
So, when the 30 Megabyte hard drive crashed George Bohn ordered a new hard drive from the IT department in Oklahoma City. A couple of weeks later, we received the new hard drive from the city. George gave it to me and asked me to install it in the computer.
When I installed the hard drive, I found that it had already been formatted. All I had to do was install the program and we were good to go. I backed up the program from the Unit 1 computer and copied it onto the new hard drive using a floppy disk. Yeah. Programs were a lot smaller then. A 360 Kilobyte floppy disk was all that was needed to hold the entire Precipitator program.
I noticed right away that instead of being the 30 Megabytes we had expected, there was only 20 Megabytes on the drive. That was all right with me. 20 Megabytes would be enough so that we didn’t have to back anything up very often.
As I was installing the program and testing it, and going through the code figuring out how to change Unit 1 to Unit 2, I had an idea…. At the command prompt, I typed “D:” and hit enter. You know what I was checking, right? D colon, and enter…..
sure enough. there was a D drive on this hard drive. Another 20 Megabytes were on this partition. You see. This was actually a 40 Megabyte hard drive that had been partitioned as two 20 megabyte drives.
It was at this point that I thought I would play a little joke on George. I figured he would come and look at this computer and at first he would find that the new hard drive was only a 20 Megabyte drive instead of the 30 Megabyte drive that he had ordered. I also figured that like me, he would think about it for a minute and then check to see if there was an extra partition and would find the extra drive.
So I thought I would leave him a little present. I went to D Drive and at the command prompt (gee… the only thing you had was a command prompt. You didn’t even call it a command prompt then. You called it a DOS prompt) that looked like this: D:> I typed – “label d: Bohns Boner” For all you older DOS people, you know what this did, right? It labeled the D drive volume name “Bohns Boner”. At the time I think we were on DOS 4.0 or something close to that. The volume length was limited to 11 characters and Bohns Boner took exactly 11 characters. The label couldn’t be longer than that.
Now, all I had to do was call up George Bohn, tell him I had installed the hard drive in the precipitator computer and it was up and running and go to the electric shop and wait for him to come down with a smile on his face over the name of the second drive on the computer. So I did. I told Charles Foster and Terry Blevins.
After the reorganization, Tom Gibson, our Electric Supervisor had decided that Terry Blevins would maintain the precipitator on Unit 2, and I would maintain Unit 1, which was great for me, because I was no longer working on both of them by myself. So, Charles and I were waiting for George to arrive in the electric shop office. It didn’t take long.
George came in the office and said, “Did you see that they only gave us a 20 Megabyte hard drive instead of a 30 Megabyte drive. (Oh. So, he hadn’t found the second partition). I replied, “Yeah. I noticed that.” George was a little perturbed that he didn’t get what he ordered. He said he was going to contact them and have them send us a 30 Megabyte drive. We had paid for it. I told him that he should. Especially since we had paid for it (keeping a straight concerned look on my face).
Anyway, a couple of weeks went by and there was no new hard drive, and George hadn’t said anything more about it. I thought he might have eventually found the second drive, but then he would say something like “I can’t believe they didn’t send us the right hard drive” and I would know that he still hadn’t figured it out.
One day the operators came to me and pulled me aside and asked me if there was some way when they were on the night shift if they could use the precipitator computer to create documents. At this time PCs were pretty sparse. The only good computers in the control room were these two precipitator computers and the Shift Supervisor’s office. the Precipitator computers just sat there monitoring the precipitator all the time, even when no one cared.
The plant had purchased so many licenses to use Word Perfect, a word processor that was the “in thing” before Windows and Word came around. So, I installed Word Perfect for them on the extra drive on the Unit 2 precipitator computer. That is, Bohns Boner. I explained to them that they could only use it when George Bohn was not around, because he didn’t know the drive existed and I wanted him to find it himself someday.
Word Perfect for DOS
Everyone agreed. All the Control Room operators that were at all interested in creating documents, like Jim Cave and Dave Tarver and others, knew about Bohns Boner, and knew that it was a secret.
The Control room had a laser printer installed next to the Shift Supervisor’s office so they could print out Clearances and have them look nice. They had some new Clearance system they installed, and this came with it. So, the next question was… Is there a way we can print our documents out using the Laser Printer instead of the clunky Dot Matrix printer tied to the Precipitator computer?
I ordered a 50 foot Printer cable (I paid for it out of my own pocket) and kept it coiled up under the small desk where the precipitator computer sat and explained that they could just disconnect the dot matrix printer on the back of the computer and plug the other end into the Laser Printer and they could print out nice neat looking documents. But… They had to do it at night or when they were sure that George Bohn was not around because he still didn’t know the extra drive existed. Everyone agreed. They would have to string the printer cable across the Control Room floor to reach the laser printer.

Like I said earlier. this went on for well over 6 months. It seemed like almost a year. Then one day, George Bohn came down to the Electric Shop office while Charles and I were sitting there for lunch. He said that he had asked Oklahoma City about the hard drive again, and they had insisted that they had sent the correct hard drive to our plant. Then we could see a light go on in his head. He said, “Do you suppose that they partitioned the disk into two drives?” (Bingo! He had figured it out). I said, “Could be.”
Charles and I sat there and looked at him while we ate our lunch. The cherry tomatoes Charles had given me tasted especially good with my ham and cheese sandwich that day. I knew that we were finally only minutes away from the end of the joke we had been playing on George for the past so many months. George leaned back in the chair with his thin long legs stretched out and his hands behind his head. I could tell he was thinking about it.
Then he rose from his chair and headed out the door. Charles and I smiled at each other. We both waited. A few minutes later George came back in the office. He had found Bohns Boner. You see. When you went to a drive back then on the command prompt, the first thing you would see was the volume name. So as soon as he typed the D colon and enter, it would have said “Bohns Boner”.
George sat down in a chair. He didn’t say anything. He just sat there with a straight face as if he didn’t know what to think. I thought…. well, he is an Engineer. Maybe he doesn’t know what to do when Power Plant Men play jokes on them. He looked like he couldn’t decide whether to be upset or glad that we had an even bigger hard drive than he ordered. I don’t know if he ever figured out that the longer the joke takes, the more we liked him.
I guess George felt foolish that it took him so long to find that extra drive. I suppose he might have thought he knew me well enough that if there had been an extra drive on the computer, when he first mentioned it, I would have told him that it was partitioned into two drives, so he didn’t give it a second thought. I guess he didn’t know me as well as he thought.
Anyway, after that, he never said anything about the operators using the computer for other uses than monitoring the precipitator, which was always a problem before. George never mentioned the hard drive again. I don’t remember now if I later changed the volume name on the drive. It seemed like not long after the computers were upgraded from the IBM AT to something like a XT 286.
Oh. I had another joke I played on George. The other one lasted for years, and he never figured it. I will write about that one later. That one wasn’t so much of a joke as it was out of necessity. I won’t say anymore about it now. You’ll have to wait at least another week or two.
Power Plant Paradox of Front to Back and Back to Front
Originally posted February 8, 2014:
After the downsizing in 1987 some new engineers were assigned to the coal-fired Power Plant in North Central Oklahoma. I wasn’t used to an engineer actually pausing to listen to what I was saying. I remember the first time I said something sort of out of the ordinary and Doug Link stopped and asked me why I thought that. The usual response was to roll their eyes as if I was some dumb electrician that almost knew how to lace my boots correctly… Ok… Lacing your boots isn’t as easy as it looks…. especially when you put them on in the dark in the morning before you leave the house.
I chose this picture because they look like my boots, only I never wore the toes out so that you could see the steel toes.
Now, before you think “Front to Back and Back to Front” has to do with lacing up my boots, you are mistaken.
Back to Doug Link. I was surprised when he actually stopped and asked me to explain myself. I know I had said something that had sounded a little bombastic, but what I believed to be true anyway. So, I sat down and explained it to him. It was something that ran contrary to what a person might think was logical. Once I explained it to him, he said he understood what I meant. — Wow. What kind of new engineers are they breeding out there (I thought). Well he did go to Missouri University at the same time I did, we just didn’t know each other at the time.
Doug Link
Another engineer that showed up at the plant was Toby O’Brien. Even the maintenance department recognized right away that Toby would listen to you. Not only would he listen to the crazy rantings of an electrician like me, but he would also ask advice from mechanics! And… (now brace yourself for this) Welders! I believe that if he could corner a janitor, he probably would have listened to them as well…. because… well… I was just a janitor pretending to be an electrician, and he listened to me all the time.
So, what does this all have to do with “Front to Back and Back to Front”? Well. Almost nothing. Except that these new engineers knew about a secret that we were all keeping from George Bohn, another engineer that I talked about in the post “Bohn’s Boner and the Power Plant Precipitator Computer” In that post we had kept from George that the computer had an extra drive partitioned on the hard drive for a while. In this post, I will talk about a much more significant secret (at least in George’s eyes).
With the reorganization Terry Blevins worked on one precipitator and I worked on the other.
Terry Blevins
For those of you who don’t know, the precipitator is what takes the “smoke” out of the exhaust from the boiler so that it can be collected in hoppers and sent up to the coalyard to silos where trucks would come and haul it away to make highways.
Fly Ash Hoppers underneath the precipitator
The electric Supervisor Tom Gibson thought that a little competition would be good between the two teams to see who could make their precipitator work the best. Only it didn’t work out that way. Terry had one way of doing things and I had a completely opposite way of approaching a problem. Terry would study a problem. Analyze it, and do everything he could to understand what was going on. Then he would go out and make a major change. I on the other hand would make incremental small changes and observe the effects. Then work toward what seemed to work best.
Between the two of us approaching a problem from completely different points of view, we were able to come up with solutions that apart I don’t think either of us would have ever thought about. So, we became a team instead.
Now for the boring part of the story. I am going to explain Back to Front….. With the new digital controls, we could set up the controls so that each of the 84 precipitator transformers could be backed down one KV (kilovolt) at a time in order from the front cabinets to the back ones. Then it would start from the front again backing the power on the cabinets down slightly each time. — I know this is boring. The front of the precipitator is where the exhaust enters the precipitator. The back is where the exhaust leaves the precipitator.
The cabinets would do this until the amount of ash going out of the smoke stack hit a certain limit that was 1/4 of the legal limit (the legal limit was 20% opacity. So, we controlled the cabinets to keep the opacity at 5%). Opacity is the amount of light that is blocked by the ash coming out of the smokestack.
Well, if the opacity went too high (say 6.5%) the back cabinets would start powering all the way back up, and it would work its way toward the front of the precipitator from the back until the opacity went down below the set limit. — sound good? Well… after running this way for a while we realized that this wasn’t so good.
What ended up happening was that the front cabinets which normally collected 90% of the ash were always powered down and the back cabinets were powered up, because they would power up each time the opacity would spike. So the ash collection was shifted from the front to the back. This meant that if there was a puff of ash going out of the stack, it probably came from the back of the precipitator and there wasn’t anything that could be done to stop it.
We asked George if we could reverse the Front to Back powering down of the cabinets so that it went from Back to Front. That way the back of the precipitator would be powered down most of the time and the front would be powered up. This would keep the back half of the precipitator clean and if there was a need to power them up because of some disturbance in the boiler, the back of the precipitator would be in good shape to handle the extra ash.
George, however, insisted that since the EPA had tested the precipitator with the new controls when they were setup to go from front to back, we couldn’t risk changing it, or the EPA could come back and make us put scrubbers on the plant. We were grandfathered into not needing scrubbers and we didn’t want to go through that mess and cost that would have raised electric rates for everyone.
This was frustrating because we could easily see that every hour or so we would be sending big puffs out of the smokestack on the account of the inherent flaw of backing the cabinets down using a Front to back method. Even though we knew the engineers would blow their top if they found out, we called the EPA one day and asked them about it. The EPA said they didn’t care as long as the precipitator wasn’t physically being altered and we were adjusting the controls to maximize operations.
So, one day when I was in the Precipitator Control Room, I walked over the main processor unit in the middle of the room where the seven sections of 12 cabinets each plugged in. I took the A row cable and swapped it with G. I took B and swapped it with F, C and swapped it with E. D I just left it where it was since it was in the middle.
Then I walked to each Cabinet in a section and swapped the eeprom chip from cabinet 1 and put it in 12. And from cabinet 2 and put it in 11, and so on. Without leaving the precipitator control room, I had just changed the order of the cabinets backing down from “Front to Back” to “Back to Front”. As far as the control room was concerned, nothing changed (unless you looked closely at the voltages on the cabinets on the computer. The front cabinets usually were around 30kv while the back were closer to 45kv).
So, now that the cabinets were backing down from back to front, everything worked a lot smoother. No more hourly puffs and wild power swings as cabinets were released. As long as George didn’t know, he was happy. The precipitator suddenly was working very well. So well in fact that one winter while the unit was at full load (510 Megawatts), the precipitator was using only 70 Kilowatts of power and the opacity was well below the 5% threshold.
The space heaters in the precipitator control room were using over 120 kilowatts of power. More than the entire precipitator. This is important because normally the precipitator used more power than any other piece of equipment in the plant. It was not unusual before we had the back down working for one precipitator to use 3 Megawatts of power. That is 3,000 Kilowatts.
Then one day in 1992 an electrical engineer Intern (who later became a full time engineer) came in the precipitator control room with George Bohn while we were calibrating the cabinets one at a time. George began explaining to Steve Wilson how the precipitator controls worked. We were in the front section (G row). George introduced Steve to us and started explaining to him about the back down and how it worked.
Steve Wilson
Just then, the cabinet that he was showing him powered up. — oops. This was a front row cabinet and in George’s mind, they should be the last to power up. He looked around and could see that the cabinets in F row were still powered down. I thought, “The jig is up.” George said, “That’s not right! That shouldn’t happen!” (Ok George. We’ve only been doing this for 3 years and you are just now noticing?).
So, I asked him what the problem was (knowing full well). He explained that the cabinet in G row had just powered up. — You could tell when a cabinet was powered down because a certain light in the lower left corner of the display would be on. I looked at the cabinet and the Primary current limit light was lit. Obviously not in the back down mode.
So, I said this, “George, this cabinet still is in the back down mode. You just can’t tell because it is also hitting the primary current limit and both lights won’t light up at the same time.” — Geez… I thought…. would he believe this hair brain explanation? George nodded. Then he went on to explain to Steve what I just said to him as if it was something he knew all the time (even though I sort of just made it up).
A short time after Steve and George left, I found Steve and explained to him that we really do power down the precipitator from back to front instead of front to back, because front to back doesn’t work, and I explained to him why it works better and why we don’t tell George Bohn. Steve was another sensible engineer that knew how to listen and learn. I enjoyed the little time I spent working with him.
Well…. The efficiency of the precipitators caught the attention of EPRI (the Electric Power Research Institute), and they wanted to come and study our precipitator controls. Not only the back down feature we were using but also a pulse capability that Environmental Controls had that allowed you to power off for so many electric pulses and then power on again.
So, when the EPRI scientists showed up to test our precipitators for a couple of weeks trying the different modes of operation, I knew that it was important for them to really understand how we were operating the precipitators. So, after George had taken them to the computers in the control room and explained the back to front back down mode. I took them aside one at a time and explained to them that even though the computer looked like it was backing down from front to back, it was really backing down from back to front.
I explained to them why we had to do it that way, and I also explained to them why we didn’t let George know about it. They all seemed to understand, and for the next two weeks no one from EPRI let the cat out of the bag.
To this day I don’t think George knew that we had swapped the direction of the back down from “front to back” to “Back to front”. At least not until he reads this post.

Now I know why George came into my office one day and begged me to have you committed!
Great story!

Yeah. That’s one of the reasons. 🙂

I really appreciate how you describe the two methods of problem solving, and how together you could come up with solutions that neither one of you may have thought of.

Thanks for your comment Monty. It was annoying at first. I kept wanting Terry to see my point of view. Then I started seeing the benefit of taking both approaches.

Toby O’Brien and Doing the Impossible
Originally posted May 23, 2014:
There were three times when I was an electrician at a coal-fired Power Plant in North Central Oklahoma when, according to others, I had done something that they labelled “impossible”. One of those times began when a Plant Engineer Toby O’Brien came to me and asked me if I could find a way to connect to the Prime Computer down at Corporate Headquarters so that he could edit some Engineering drawings he had worked on when he was working at Oklahoma City. That in itself wasn’t what was impossible. That came later, but it pertained to a similar subject.
Somewhere in Corporate Headquarters stashed away in a room somewhere was a Prime Computer just waiting for Toby.
Prime Computer
Toby knew that I had an account on the Honeywell Mainframe computer downtown, since I was always getting myself in trouble playing around on it. Since I could connect to that, he wondered if it would be possible to connect to the Prime Computer where his Medusa CAD drawings were kept. He gave me some information about how he used to log into it when he was working downtown…. before he was banished to the Power Plant Palace 70 miles north out in the middle of the country.
Toby had a CAD tablet and a disk to install the driver on a computer. This would allow him to work on his CAD drawings. For those of you who don’t remember, or have never seen such a thing. It is like a very fancy mouse…. or should I say, Mouse Pad. Since you used a stylus to draw and point and click on a large pad called a tablet. Not anything like the little tablets we have today.
CAD Drawing Tablet
At the time, the only connection we had to the Honeywell Mainframe from the power plant was through a router called a Memotec. The bandwidth was a whopping 28,000 baud. A Baud is like bytes per second, only it is measured over an audio line as an audio signal. Like the sound that a Fax machine makes when it first connects. Toby had talked to some guys down at IT and they had a copy of the same Honeywell emulator called “GLink” we were using at the plant, only it would connect at a super whopping 56,000 baud. Twice as fast! They wanted someone to “Beta Test” it. They knew I liked doing that sort of stuff, so they were willing to give us a copy to try out.
This is GLink today. Back then it was for Windows 3.1
Toby and I decided that the best place to try out our “Beta Testing” was in the Chemistry Lab. The main reason was that it had one of the newer 386 desktop computers and it was in a room right next to the data closet where the Memotec was talking to the mainframe downtown. So, if I had to run in there real quick and spit in the back and “whomp it a good ‘un”, I wouldn’t have too go far. That was a trick I learned from watching “No Time for Sergeants” with Andy Griffith. Here is the lesson:
If you have trouble viewing the video from the picture above, this this link: “No Time For Sergeants Radio Operator“.
To make the rest of this part of the story a little shorter, I’ll just summarize it to say that by logging into the Honeywell Mainframe using my account, I was then able to connect to the Prime Computer using Toby’s account and he was able to edit his CAD drawings from the Chemistry Lab at the Power Plant 70 miles away from Corporate Headquarters. I know that doesn’t sound like much, but in those days, this was “new technology” for us Power Plant guys anyway.
Before I continue with the “impossible” task, I need to explain a little about how electricians kept the Electrical Blueprints up-to-date at a Power Plant. This was a task that I was given when Tom Gibson was the Electrical Supervisor. I was supposed to take all the blueprints that had been revised because of some change that had happened at the plant, and make sure they were properly updated. Then I had to go through a process to make sure they were permanently updated, not only on the three copies that we had at our plant, but also with the “System of Record” set of blueprints at Corporate Headquarters.
So, let me tell you the process, and I’m sure you will be able to relate this task to something you encounter in your job today. Even if it is preparing the Salads at a Sirloin Stockade before opening time.
The first step happens when someone in the electric shop has to rewire some piece of equipment or something because the equipment was moved, removed, upgraded to something else, or someone thought it would work better if we did it a different way. Then whoever made the change to the electric wiring would go to the prints that were kept in the electric shop and update them so that the new wiring job was reflected in the Blueprints.
This is important because if someone a week later had to go work on this equipment, they would need to be able to see how the equipment is now wired. If they were working off of an old print, then they might blow something up, or injure or even kill someone…. most likely themselves, if it ever came down to it.
The other two copies of prints also needed to be updated. One was in the Instrument and Controls shop, and the most important copy was in the “Print Room” right next to Tom Gibson’s office.
The second step was to send off a request to Corporate Headquarters in Oklahoma City for a copy of all the blueprints that were changed so that the change could be made on the copy and sent back to Oklahoma City.
The third step is when a fresh copy of the blueprints arrived at the plant from Oklahoma City a few weeks later. These were updated with the changes and sent back to Oklahoma City.
The fourth step is when the blueprints are reviewed by an engineer downtown and the changes are made permanently by a drafter downtown.
Step five: Then three copies of the permanently changed prints were sent back to plant where they replaced the three marked up copies.
This process generally took two to three months given that the drafter downtown had to take the Original drawing, scan it in the computer, make changes to it, and then save it, and send it to the printer to be printed.
Toby and I had “petitioned” our plant management to buy us a copy of AutoCAD so that we could make our own revisions right at the plant, and send the changes directly to Oklahoma City, all complete and ready to go. The only problem with this was that AutoCAD software did not come cheap. It was several thousand dollars for just one copy.
Even though this was before the World Wide Web, I knew where I could get a pirated copy of AutoCAD, but since neither Toby or I considered ourselves criminals, we never really considered that a viable alternative. Tom Gibson was pitching for us to have a copy, but it was figured that if we had a copy, the company would have to buy a copy for all six main power plants, and they weren’t willing to dish out that much money.
Somewhere along the line, after Tom Gibson had kept pushing for the importance of having up-to-date Plant Electric Blueprints in a timely fashion, a task force was formed to address a faster way to make print revisions. Because Toby and I (and Terry Blevins) had been pushing this at our plant, Tom asked Toby and I (actually, that should be “Toby and me”, but “Toby and I” makes me sound smarter than I am) to be on the Task Force with him.
So, one morning after arriving at the plant, we climbed into a company car and made the drive to Oklahoma City to the Corporate Headquarters. When we arrived, we sat in a big conference room with members from the different power plants, and a number of engineers from downtown. I was pretty excited that something was finally going to be done.
I don’t remember the name of the engineer that was the leader of the task force, I only remember that I had worked with him once or twice through the years on some small projects. When the meeting began, I expected that we would have some kind of brainstorming activity. I was all ready for it, since I had all sorts of ideas about how we could just edit the prints directly from the plant on the Prime Computer where the prints were stored, just like Toby had done.
When the meeting began there was no brainstorming session. There wasn’t even a “What do you guys think about how this can be done?” No. The engineer instead went on to explain his solution to the problem. I was a little disappointed. Mainly because I was all fired up about being asked to be on a task force in Oklahoma City to work on…. well…. anything…. to tell you the truth. And here we were listening to a conclusion. — Sound familiar? I knew it would.
This engineer had it all figured out. Here was his solution:
Step 1: A request was sent by company mail to downtown (same at the old second step) for some blueprints that need to be updated.
Step 2: The prints are downloaded onto a floppy disk (3.5 inch High Density – which meant, 1.44 Megabyte disks).
Step 3: The disks were mailed through company mail back to the Power Plant.
Step 4: The Power Plant receives the disks and loads them onto their computer at the plant and they edit the blueprint using a pared down CAD program called “RedLine”.
Step 5: The print revision is saved to the disk and the disk is mailed back to Corporate Headquarters using the Company Mail.
Step 6: The print is reviewed by the engineers for accuracy and is loaded into the computer as the system of record.
Ok…. this sounded just like the previous method only we were using a “RedLine” program to edit the changes instead of using Red, Green and Gray pencils.
It was evident that the engineer in charge of the meeting was expecting us to all accept this solution and that the task force no longer had to meet anymore, and we could all go home and not ever return to consider this problem again. — Well, this was when I said the “Impossible”.
I raised my hand as if I was in a classroom. The guy knowing me to be a regular troublemaker asked me what I wanted. I said, “Why mail the files? Why not just put them in a folder and have the person at the plant go there and pick them up?” — In today’s world the idea of a drop-box is about as easy to understand as “Google it”. Back then… I guess not. Especially for some engineers who had already decided on a solution.
So, the engineer responded, “Because that can’t be done.” I said, “Why not?” He said, “It’s impossible. Someone in a power plant can’t just go into a computer at Corporate Headquarters and access a file.”
Well, that did it….. I told him that we were able to edit CAD drawings on the Prime computer from the power plant. He said, “No you didn’t. That’s impossible!” I looked over at Toby who was sitting next to me with a big grin on his face. So I said, “Who is the IT guy in the room? He can tell you that you can get a file from the mainframe from the power plant.”
The engineer replied that he didn’t invite any IT people, because there wasn’t any reason. Everyone knows that you can’t copy files on a Corporate computer from a power plant. So, I said, “Invite someone from the IT department to the next meeting. I’m sure he will agree with me that this can be done. — Shortly after that, the meeting was adjourned (but at least I had managed to convince the team we needed a second meeting).
You should have heard me rant and rave all the way back to the power plant that afternoon. How could he possibly be so naive to make definite statements about something and basically call me a liar when I said that we had already done it. I’m sure Tom Gibson was glad when we arrived back at the plant and he was able to get out of the company car and into the silence of his own car for his drive back to Stillwater. Toby on the other hand carpooled with me, so he had to hear me rant and rave to Scott Hubbard all the way back to Stillwater that day.
Needless to say, we had another Print Revision Task Force meeting a few weeks later. Tom, Toby and I drove back to Oklahoma City. I couldn’t wait to see what was going to happen.
The meeting began with the engineer in charge of the task force saying, “The first thing we are going to address is Kevin Breazile’s statement about sending files to the power plant. We have invited someone from IT to answer this question.” Then he turned to a guy sitting at the table. I don’t remember his name either, only that I had worked with him also through the years (oh yes I do. It was Mike Russell).
The engineer turned to the IT guy and said (using a tone that indicated that I belonged in a mental institution or maybe kindergarten), “Kevin seems to think that he can somehow get on his computer at the power plant and access a folder on a server here at Corporate Headquarters and download a file.” He stopped and with a big smirk on his face looked at the IT guy. Mike just sat there for a moment looking at him.
The engineer just stood there with an evil grin on his face waiting… Mike said, “So? What do you want to know?” The engineer said, “Well. Is that even possible?” Mike replied, “Of course! It’s actually easier for him to do that than it is for someone on the 3rd floor of this building to access the mainframe on the fourth floor.”
The engineer’s jaw dropped and he eked out a meager little “what?” Mike asked if that was all. When he was assured that this was the only question, he stood up and walked out the door. As he was leaving he turned a side glance toward me and winked at me. I was grinning ear-to-ear. I could tell, I wasn’t the only one that had a beef with this particular engineer.
So, you would have thought that it would have been a quieter ride back to the plant that day, but leave it to me…. I kept on going on about how that guy was so sure of himself that he didn’t even bother to ask the IT guy before the meeting began just to check his own erroneous facts. Geez! That was the most surprising part of the day. If he had only asked him before the meeting, he wouldn’t have made a fool out of himself with his snide comments just before he was put in his place.
So, Toby and I proved that doing the impossible isn’t all that impossible when what someone thinks is impossible really isn’t so. This stemmed from a lesson my dad taught me growing up when he told me, “Don’t ever say “can’t”. There is always a way.”

Great story! I heard a pastor once say “What you “know” can keep you from learning the truth.” I saw this principle in operation many times in my career.
I had been at the WFEC Hugo Power Plant for a short time when the Plant Manager directed me (Maint. Supt.) to have the Mechanics “block the condenser” for a “hydro”. (Prior to a condenser hydro, several mechanics would work for about 4 hours dragging heavy timbers into the 3 foot tall space between the bottom of the hotwell and the concrete floor. They would space these timbers evenly across the entire condenser floor and use wedges to remove all clearance at each support beam. All this work was “required” to support the additional water weight (several feet higher than normal operating level)). I knew this “blocking” was never done at any OG&E plant but I didn’t want to make the Plant Manager look like an idiot. So I did what he asked. We “blocked” the condenser for a hydro. Then I got with just the Plant Engineer and asked him to get the Mechanical Prints for the condenser. I asked him if it was necessary to block the condenser for hydro. He said they had always done it because of the extra weight of the water. When we looked at the condenser drawings there was a note indicating it was designed to support a full hydro water level. He showed the print to the Plant Manager (one on one). Nobody was made to look foolish and for the next condenser hydro we didn’t “block” it – and the Mechanics were really happy!

We used to have a saying that I picked up from Bob Kennedy. “We’ve been doing it this way for 35 years. “

Well over the years there were a lot of engineers that way. Not all. We have had outstanding ones as well and the stinkers too. Just hate the politics of people so evil and cruel. Man is beyond ugly so often.
Power Plant Genius of Larry Riley
Originally posted February 25, 2012. I added Larry’s Picture at the end:
When I first began working at the power plant (in 1979), one of the people I spent a good deal of time with was Larry Riley. I was 18 and knew very little about tools, equipment, power plants and how to speak in the Power Plant language. I quickly found out that in those early days, when the plant was still under construction, a lot of people turned to Larry Riley when they were faced with an obstacle and didn’t know how to approach it.
Larry Riley was a 24 year old genius. I was amazed by his vast knowledge of seemingly disparate areas of expertise. When he was asked to do something, I never heard him say that he didn’t know how. He just went and did it. So, after I asked Larry how old he was, I asked him how long he had been at the plant. He hadn’t been there very long, but he had worked in the construction department before transferring to the power plant.
Larry Riley already at the age of 24 had a beat up hard hat full of hard hat stickers. One indicating that he was a certified industrial truck driver. I think he had about 5 safety stickers and various other hard hat stickers. He was a thin clean cut dark haired young man with a moustache that sort of reminded me of the Marlboro Man’s moustache. He walked like he had a heavy burden on his back and he was rarely seen without a cigarette in his mouth.
Yep. That’s the Marlboro Man
I worked with Larry off and on throughout my years as a summer help and during that time Larry taught me the following things (to name a few): How to drive a tractor. How to mend a fence. How to bleed the air out of a diesel engine’s fuel line (which is more important than you would think). How to operate a brush hog (a large mower on the back of a tractor). How to free a brush hog from a chain link fence after you get one of the bat wings stuck in one. Tie rebar, and pour concrete and operate a Backhoe.
I remember asking Larry why a backhoe was called a backhoe. I think Sonny Karcher was in the truck at the time. You would have thought I had asked what year the War of 1812 was fought! I’m sure you are all chuckling while reading this (especially all the power plant men). But for those of you who are as green as I was, I’ll tell you. A Backhoe is called a Backhoe because the Hoe is on the Back. Gee. Who would have thought?

Here is a picture of a backhoe
Later when I was a full time employee and had worked my way from being a Janitor to being on the Labor Crew, Larry Riley became my foreman. At that point on occassion I would call him “Dad”. He would usually disown me and deny that he had anything to do with it. On occassion when he would own up to being my dad, he would admit that when I was real little I was dropped on my head and that’s why I acted so odd (though, I don’t know to what behavior he was referring).
There was this other guy at the plant the first summer I was there that had the unique title of “Mill Wright”. His name was Gary Michelson. He evidently had gone to school, taken some tests and been certified as a Mill Wright and this probably brought him a bigger paycheck than the other regular workers as well as a much bigger ego.
Gary would spend days at a time at a band saw cutting out metal wedges at different angles so that he would have them all in his pristine tool box. I worked with him a few times during my first summer as a summer help. I will probably talk more about Gary in a later post, but just to put it plainly… I could tell right away that he wasn’t a real “power plant man”.
The rest of the power plant men I’m sure would agree with me. I wouldn’t have traded Larry Riley for ten Gary Michelsons unless I was trying to help some engineers change a light bulb (actually. I have met some good engineers along the way. Some of them very good. But they were not the norm. At least not those assigned to power plants).
I have mentioned some different things that Larry had taught me and if you remember, he was the person that I worked with on my second day at the plant when Sonny Karcher and Larry had taken me to the coalyard to fix the check valve (in my post about Sonny Karcher). There will always be one day that first comes to my mind when I think about Larry. This is what happened:
I drove a truck down to the Picnic area on the far side of the lake from the plant. Jim Heflin drove a Backhoe down there. I believe he was going to dig up some tree stumps that had been left over after the “engineers” in Oklahoma City had decided where to put all the trees in the area.
What the engineers in Oklahoma City did was this: They cut down all of the trees that were in the picnic area and planted new trees. Some of them not more than 15 or 20 feet away from a tree that had been there for 30 years and was a good size. So, there were a lot of stumps left over from the big hearty trees that had been cut down that needed to be removed so that the sickly little twigs that were planted there could prosper and grow without feeling inadequate growing next to a full grown he-man tree.
Anyway. I had climbed out of the truck and was making my way around the picnic area picking up trash and putting it in a plastic bag using a handy dandy homemade trash stabbing stick. As Jim was making his way across the “lawn” (I use the word “lawn” loosely, since the area was still fairly new and was not quite finished) when he hit a wet spot. The Backhoe was stuck in the mud.
There wasn’t much I could do but watch as Jim used the hoe to try to drag himself out. He rocked the backhoe back and forth. Use the stabilizers to pick up the backhoe while trying to use the scoop to pull it forward. I would say he worked at it for about ten minutes (even though it seemed more like half an hour). Eventually it was time for us to head back to the plant to go to break.
Back at the plant, Jim told Larry about his predicament and asked him if he would help him get the backhoe out of the mud. Larry said he would come along and see what he could do. At this point, I was thinking that he would jump in the Wench Truck and go down there and just pull him out. Instead we just climbed in the pickup truck and headed back to the park (notice how it went from being a picnic area to a park in only three paragraphs?).
When we arrived, Larry climbed into the Backhoe after making his way across the vast mud pit that Jim had created while trying to free himself before. He fired up the Backhoe…. cigarette in mouth… then the most fascinating thing happened… using both feet to work the pedals, and one hand working the controls in the front and the other hand working the levers in the back, Larry picked up the backhoe using the scoop and the hoe and stabilizers and cigarette all simultaneously, he walked the backhoe sideways right out of the mud pit and onto dry land just as if it was a crab walking sideways. I would say it took no longer than three minutes from the time he started working the controls. Jim just looked at me in amazement. Patted me on the back, shook his head and said, “And that’s how it’s done.”
This is the best picture I could find of Jim Heflin
Now that I’m on the subject of Larry Riley on a backhoe, let me tell you another one. I have seen Larry digging a ditch so that we could run some pipe for irrigation. Now picture this. The bucket on the backhoe is digging a hole in the hard red clay of Oklahoma, and Larry suddenly stops and says….. “I think I felt something”. What? (I think) Of course you did, you are operating this machine that has the power to dig a big hole in the ground in one scoop like it was nothing and Larry said he felt something?
He climbed off of the backhoe, jumped down into the ditch he was creating, kicked some clods of dirt around and lo and behold, he had just scraped clean a buried cable. He hadn’t broken it. He had come down on it with the bucket and had somehow “felt” this cable buried under all that dirt. I wonder what it felt like that told him he had encountered something that wasn’t just dirt. I think the entire labor crew just went down on one knee before his greatness for a moment of silence – all right, so we didn’t really. But we were somewhat impressed.
The one thing that makes Larry a True Power Plant Man with all the rest is that he performed acts of greatness like what I described above with complete humility. I never saw a look of arrogance in Larry’s face. He never spoke down to you and he never bragged about anything. To this day, I still picture Larry Riley working at the power plant working feats of magic that would amaze the rest of us as he thinks that he’s just doing another day’s work. That’s the way it is with True Power Plant Men.
Since I first created this post two years ago, I have found a picture of Larry Riley taken many years after this story:

When Power Plant Durability and Automation Goes Too Far
Everyone expects when they enter an elevator and push a button for the 3rd floor that when the doors open they will find themselves on the third floor. It doesn’t occur to most people what actually has to happen behind the scenes for the elevator to go through the motions of carrying someone up three stories. In most cases you want an automated system that requires as little interaction as possible.
I have found while working in the Coal-fired Power Plant in North Central Oklahoma that some systems are better off with a little less than perfect automation. We might think about that as we move into a new era of automated cars, robot soldiers and automatic government shutdowns. Let me give you a for instance.
The coal trains that brought the coal from Wyoming all the way down to the plant would enter a building called “The Dumper.” Even though this sounds like a less savory place to park your locomotive, it wasn’t called a Dumper because it was a dump. It was called a Dumper because it “Dumped.” Here is a picture of a dumper:
A rotary dumper much like the one that was at our Power Plant
The coal train would pull into this room one car at a time. I talked about the dumper in an earlier post entitled “Lifecycle of a Power Plant Lump of coal“. As each car is pulled into this building by a large clamp called the “Positioner” (How is that for a name? It is amazing how when finding names for this particular equipment they decided to go with the “practical” words. The Positioner positions the coal cars precisely in the right position so that after the car clamps come down on the car, it can be rotated upside down “Dumping” the coal into the hoppers below. No fancy names like other parts of the power Plant like the “Tripper Gallery” or the “Generator Bathtub” here.
A typical coal train has 110 cars full of coal when it enters the dumper. In the picture of the dumper above if you look in the upper left corner you will see some windows. This is the Dumper Control Room. This is where someone sits as each car pulls through the dumper and dumps the coal.
Not long after the plant was up and running the entire operation of the dumper was automated. That meant that once put into motion, the dumper and the controls would begin dumping cars and continue operating automatically until the last car was through the dumper.
Let me try to remember the sequence. I know I’ll leave something out because there are a number of steps and it has been a while since I have been so fortunate as to work on the dumper during a malfunction… But here goes…
I remember that the first coal car on the train had to positioned without the positioner because… well….. the car directly in front of the first car is, of course, the locomotive. Usually a Burlington Northern Santa Fe Engine.
A picture from Shutterstock of a locomotive pulling a coal train
Before I explain the process, let me show you a picture of the Positioner. This the machine that pulls the train forward:
The piece of equipment with the large wheels is the positioner It can pull a coal train full of coal forward to precisely the proper position
The automation begins after the first or second car is dumped. I’ll start with the second car just finishing the process as it rolls back up right after dumping the coal… The car clamps go up.
- The rear holding arm (that holds the car in place from the entrance side of the dumper) lifts up out of the way.
- The Positioner begins pulling the entire train forward.
- Electric eyes on both end of the dumper detect when the next car has entered the dumper.
- The Positioner adjusts the position of the coal car to the exact position (within an inch or two) by backing up and pulling forward a couple of times.
- The Holding arm on the back end comes down on the couplings between the two train cars one back from the car that is going to be dumped.
- The four car clamps come down on the train car at the same time that the dumper begins rotating.
- The Positioner clamp lifts off of the train car couplings.
- Water Sprayers come on that are attached to the top of the dumper so that it wets the coal in order to act as a dust suppression.
- The Positioner travels back to the car clamp between the car that was just emptied before and the car in front of it.
- As the train car rotates to the desired angle. (I think it’s about 145 degrees), it begins slowing down.
- When the car has been rotated as far as desired it comes to a stop.
- The Dumper pauses for a few seconds as all the coal is dumped from the coal car.
- The Positioner moves back and forth until it is in just the right position for the positioner arm to lower onto the couplings between the cars.
- The Sprayers turn off.
- The Dumper begins returning to an upright position.
- The Positioner arm lowers down onto the clamps between the coal cars.
- Once the car is upright the dumper stops rotating.
- The 4 car clamps go up.
- The Holding arm goes up. And the process is repeated.
This is a beautiful process when it works correctly. Before I tell you about the times it doesn’t work correctly, let me tell you about how this process was a little…uh… too automated…
So. The way this worked originally, was that once the automated process was put into operation after the second car had been dumped, all the dumper control room operator had to do was sit there and look out the window at the coal cars being dumped. They may have had some paperwork they were supposed to be doing, like writing down the car numbers as they pulled through the dumper. It seems that paperwork was pretty important back then.
Each car would pull through the dumper… The coal would be dumped. The next car would be pulled in… etc.
Well. Trains come from Wyoming at any time of the day. Train operators were paid pretty well, and the locomotive engineers would come and sit in the control room while the train was being dumped. Often (more often than not it seemed) the trains would pull into the dumper in the middle of the night. Coalyard operators were on duty 24 by 7.
So, imagine this…. Imagine Walt Oswalt… a feisty sandy haired Irishman at the dumper controls around 3 in the morning watching 110 cars pull through the dumper. Dumping coal…. One after the other. I think the time it took to go from dumping one car to the next was about 2 1/2 minutes. So it took about 3 1/2 hours to dump one train (I may be way off on the time… Maybe one of the operators would like to leave a comment below with the exact time).
This meant that the dumper operator had to sit there and watch the coal cars being slowly pulled through the dumper for about 3 hours. Often in the middle of the night.
For anyone who is older than 25 years, you will remember that the last car on a train was called a Caboose. The locomotive engineers called it a “Weight Car”. This made me think that it was heavy. I don’t know. It didn’t look all that heavy to me… You decide for yourself:
A Caboose
Back in those days, there was a caboose on the back of every train. A person used to sit in there while the train was going down the tracks. I think it was in case the back part of the train accidentally became disconnected from the front of the train, someone would be back there to notice. That’s my guess. Anyway. Later on, a sensor was placed on the last car instead of a caboose. That’s why you don’t see them today. Or maybe it was because of something that happened one night…
You see… it isn’t easy for Walt Oswalt (I don’t mean to imply that it was Walt that was there that night.. well… it sounds like I’m implying that doesn’t it…. I use Walt when telling this story because he wouldn’t mind. I really don’t remember who it was) to keep his eyes open and attentive for 3 straight hours. Anyway… One night while the coal cars were going through the dumper automatically being dumped one by one… there was a point when the sprayers stopped spraying and the 4 car clamps rose, and there there was a moment of pause, if someone had been there to listen very carefully, they might have heard a faint snoring sound coming from the dumper control room.
That is all fine and dandy until the final car rolled into the dumper. You see… One night…. while all the creatures were sleeping (even a mouse)… the car clamps came down on the caboose. Normally the car clamps had to be raised to a higher position to keep them from tearing the top section off of the caboose.
If it had been Walt… He woke when he heard the crunching sound of the top of the caboose just in time to see the caboose as it swung upside down. He was a little too late hitting the emergency stop button. The caboose rolled over. Paused for a moment as the person manning the caboose came to a rest on the ceiling inside… then rolled back upright all dripping wet from the sprayer that had meant to keep down the dust.
As the car clamps came up… a man darted out the back of the caboose. He ran out of the dumper…. knelt down… kissed the ground… and decided from that moment on that he was going to start going back to church every Sunday. Ok. I exaggerate a little. He really limped out of the dumper.
Needless to say. A decision had to be made. It was decided that there can be too much automation at times. The relay logic was adjusted so that at the critical point where the dumper decides to dump a coal car, it had to pause and wait until the control room operator toggled the “Dump” switch on the control panel. This meant that the operator had to actively decide to dump each car.
As a software programmer…. I would have come up with another solution… such as a caboose detector…. But given the power that was being exerted when each car was being dumped it was probably a good idea that you guaranteed that the dumper control room operator actually had his eyeballs pointed toward the car being dumped instead of rolled back in his head.
I leave you with that thought as I go to another story. I will wait until another time to talk about all the times I was called out at night when the dumper had failed to function.
This is a short story of durability…
I walked in the electric shop one day as an electrician trainee in 1984 to find that Andy Tubbs had taken an old drill and hooked it up to the 480 volt power source that we used to test motors. Ok. This was an odd site. We had a three phase switch on the wall with a fairly large cable attached with three large clips so we could hook them up to motors that we had overhauled to test the amperage that they pulled to make sure they were within the specified amount according to their nameplate.
I hesitated a moment, but I couldn’t resist…. I had to ask, “Andy…. Why have you hooked up that old drill to 480? (it was a 120 volt drill). He replied matter-of-factly (Factly? Can I really say that in public?), “I am going to burn up this old drill from the Osage Plant (See “Pioneers of Power Plant Fame Finally Find Peace” for more information about Osage Plant) so that I can turn it in for a new one.
Ok. I figured there must be a policy somewhere that said that if you turned in a burned up tool they would give you a new one. I knew that Bud Schoonover down at the toolroom was always particular about how he passed out new tools (I have experienced the same thing at my new job when trying to obtain a new security cable for my laptop).
Anyway. Andy turned the 480 volts on and powered up the drill. The drill began whining as it whirled wildly. Andy stood there holding up the drill as it ran in turbo mode for about five minutes. The drill performed like a champ.
Old Power Drill
After showing no signs of burning itself up running on 480 volts instead of 120 volts, Andy let off of the trigger and set it back on the workbench. He said, “This is one tough drill! I think I’ll keep it.” Sure. It looked like something from the 1950’s (and it probably was). But, as Andy said, it was one tough drill. On that day, because of the extra Durability of that old Pioneer Power Plant Drill, Andy was robbed of a new variable speed, reversible drill that he was so craving.

Great stories!
Coal trains today have engines at the rear of the train. I hope we never try to dump one of them!
It takes about 7 hrs to dump 150 car train
Wasn’t Walt but a certain marine we won’t mention. They dumped the last car & forgot to put the car clamps in the up maximum position. They give the go ahead for the train to pull the caboose through! Instant convertible caboose! Now there are break away clamps on the north side. And there are locomotives on the rear of the train because the trains are made up of 150 cars .
Like you, I can think of several ways to automate the process without dumping the caboose but I think the operator pushing the button may be the best. Automation can get out of hand.
An engineer used to remind us: “A machine always does what you tell it to…whethr you want it to, or not.”
IF the union or the lawyers require a duty operator on an automated process, I’m all for giving him a button to push and attaching some responsibility. All automation designs are approved by Murphy…Wow! Thanks for the update Bruce!

Ah, the good old days when the best computer was the new 386. Things weren’t impossible but you had to think about it and plan quite a bit. Great stories!
Always enjoy reading and thinking about a world I wouldn’t even know about if it weren’t for your unique blog!

Great story! I heard a pastor once say “What you “know” can keep you from learning the truth.” I saw this principle in operation many times in my career.
I had been at the WFEC Hugo Power Plant for a short time when the Plant Manager directed me (Maint. Supt.) to have the Mechanics “block the condenser” for a “hydro”. (Prior to a condenser hydro, several mechanics would work for about 4 hours dragging heavy timbers into the 3 foot tall space between the bottom of the hotwell and the concrete floor. They would space these timbers evenly across the entire condenser floor and use wedges to remove all clearance at each support beam. All this work was “required” to support the additional water weight (several feet higher than normal operating level)). I knew this “blocking” was never done at any OG&E plant but I didn’t want to make the Plant Manager look like an idiot. So I did what he asked. We “blocked” the condenser for a hydro. Then I got with just the Plant Engineer and asked him to get the Mechanical Prints for the condenser. I asked him if it was necessary to block the condenser for hydro. He said they had always done it because of the extra weight of the water. When we looked at the condenser drawings there was a note indicating it was designed to support a full hydro water level. He showed the print to the Plant Manager (one on one). Nobody was made to look foolish and for the next condenser hydro we didn’t “block” it – and the Mechanics were really happy!
We used to have a saying that I picked up from Bob Kennedy. “We’ve been doing it this way for 35 years. “
Well over the years there were a lot of engineers that way. Not all. We have had outstanding ones as well and the stinkers too. Just hate the politics of people so evil and cruel. Man is beyond ugly so often.
