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.
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.
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:
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.
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.
Originally posted January 17, 2014. I added more to the story:
When I first moved to Ponca City in 1986 I carpooled each day to the Coal-fired Power Plant in North Central Oklahoma with Dick Dale, Jim Heflin and Bud Schoonover (See the post: “Carpooling Adventures with Bud Schoonover“). Dick Dale had moved to Ponca City a couple of years earlier after his divorce. He didn’t want to continue living in Stillwater where he felt as if everyone knew about his tragic situation. We had been friends from the first day we met (which is often the case with Power Plant Men) when I was a summer help working out of the garage and he worked in the tool room and warehouse.
I wrote about Dick Dale this past Christmas, when I talked about his situation (See the post: “Harmonizing with Dick Dale on Power Plant Christmas Harmonicas“). I knew that even though it was a few years later, Richard was still feeling the impact from this emotional trauma. One day I found the opportunity to play a “Power Plant” joke on him that I thought might help lift his spirits.
I recently wrote another post about how I had installed dumb terminals around the plant so that regular workers would be able to access the mainframe computer downtown in Corporate Headquarters in order to see their work orders, or look up parts in the warehouse, etc. (See the post: “Working Smarter with Power Plant Dumb Terminals“). In most places where I installed terminals, I also installed large IBM printers that printed using continuous feed paper.
For those of you who remember, at first most dot matrix printers would feed paper from a box underneath them. they had holes down both sides of the paper where the sprockets would rotate and paper would come rolling out the top of the printer.
Ok. Here is a quick one paragraph side story…
One day when my son was 5 years old, we had to wait a while in an airport. We were sitting in a row of seats at the gate waiting. My son kept popping up slowly, jerking as he rose, from behind the row of seats and would lay over the seat back and end up head down on the chair. After doing this a few times, my wife Kelly who was becoming slightly annoyed asked him what he was doing. He said, “I’m paper coming out of the printer”. Of course, this cracked us all up.
Anyway, back to the story. By the time I had to add the dumb terminals and printers to the Garage and Warehouse, I had already been playing around on the mainframe learning all sorts of ways to get into trouble. — Well, what else was I going to do during lunch while Charles Foster and I talked about movies and stuff? I had a personal user account on the mainframe that basically gave me “God Access”. They didn’t really have anything like “Network Security” back then. — This was 1988.
Back then, we also didn’t have anything called “Email” either. It wasn’t until 1989 that CompuServe first offered real Internet e-mail to its users. When we wanted to send something to someone in the company, we either printed it out and put in an intra-company envelope and sent it by “snail” mail, or we could find out what printer they used and get the ID for the printer and send it to them. It was a code like: P1234.
Well. I had been playing with this text editor on the Honeywell mainframe called FRED. This stood for FRiendly EDitor. For those of you who know UNIX, this was pretty much the same as the VI Editor found on UNIX mainframes. The commands were the same. Today, users of Microsoft Word would be horrified to find out what you had to go through to create a document back then.
I had been practicing using this editor, and found that by using the special escape codes for the printer, I could create documents that would come out looking pretty neat. So, I had created some templates that would make it look like I was printing a Memo from some mainframe program. That was about the time that I installed the printer in the garage.
So, I created a big long document that would print out on the garage printer as soon as I connected the printer to the network. It went on and on about how the printer wasn’t happy about being placed in such a dusty environment and how it refused to be cooperative until it was moved to a cleaner place. It would spit out a bunch of sheets of paper, printing protest after protest.
Then it ended up by saying that if it wasn’t moved right away, it was going to shut down in 10 minutes and it started counting down by 30 second intervals. Then at the last minute, it counted down by 15 seconds until it counted down the last 10 seconds by feeding a sheet of paper for each second while it was counting… then it paused at the last second. Finally, it printed out at the end a concession that since it was obviously not going to be moved to someplace cleaner, it might as well give up and be cooperative.
When I installed the printer in the office in the automotive garage, I knew it would take about 30 seconds to connect the first time, and by that time, I was outside making my way back to the electric shop. By the time I arrived back in the electric shop Charles Patten, the foreman in the garage was calling me on the gray phone. The gray phone is the plant PA system:
Of course, I knew why. I answered the phone and Charles told me that something was wrong with the printer. It kept shooting paper out of it and wouldn’t stop. He had even turned it off, but when he turned it back on, it still kept feeding paper out. I told him that sounded pretty strange to me and I would be right over to see what was going on. I took my time returning to the garage giving the printer time to throw it’s tantrum.
By the time I returned, the printer had stopped ranting about being installed in a dirty environment and had given up it’s protest. Charles said that it finally stopped. I walked over to the printer and took the pile of hundred or so pages that it had printed out, and tore them off the printer and walked out with them. I don’t even know if Charles had paid any attention to what the printer was saying.
I think I was the only person that knew that I had just “attempted” to play a joke on Charles. After all, as the paper was feeding out it was carefully collecting into a nice stack in front of the printer on the floor, and unless someone picked up the stack and looked at it, they wouldn’t know that anything was even printed on it. So, in this case, the joke may have been on me. But then again, Power Plant Men are like that. If they figure a joke is being played on them, then they figure out how to turn it around so that the joker is the one that has the joke played on them. Maybe that was the case here. Charles Patten was probably one of the most intelligent foremen at the plant, so it was possible.
Anyway, back to Dick Dale. I installed the printer in the warehouse and Dick Dale, Darlene Mitchell, Mike Gibbs and Bud Schoonover were happy to be connected to the Inventory program on the mainframe….. um… yeah. sure they were…… especially Bud.
Bud Schoonover was the person that when it was his turn to run the tool room would not give you something if it was the last one. So, if I needed a flashlight and it was the last one, and I asked Bud for a flashlight, he would say that he couldn’t give it to me. Why? You might ask. Well, he would explain that if he gave the last one away, he would have to order some more. Bud didn’t like ordering things on the computer. So, in order to keep from having to order anything he simply didn’t give away the last one of any item.
Anyway. I decided one Monday during my regular lunch time computer educational moments to send a letter over to the warehouse printer addressed to Dick Dale. It was from an anonymous woman. The letter sounded like it was from someone that really had a thing for Richard and remembered how they used to work together. It also mentioned other people, like Mike Gibbs and Pat Braden and about how they used to hang around each other.
Since this was a fictitious character, I could say anything I wanted, but I wanted to put it in a time period back when I was still a summer help. Well… It wasn’t long before Dick Dale called me on the gray phone (no. I won’t post another picture of the gray phone here. I think you get the idea). He asked me to come over to the warehouse.
When I arrived, Richard showed me the letter. He was excited about it. He was trying to figure out who it could be. He thought about the people that had moved from the plant to Corporate Headquarters and wondered if it was one of them. I thought for a little while, and I couldn’t come up with who it might be (obviously), since it was me.
The next day at lunch I sent another letter to his printer. I mentioned more about the “old days” working at the plant. On the way home Richard showed it to me. I could tell that he was really excited about this. I held back my smile, but inside it felt real good to see that Richard had finally come back to life. For the past couple of years, he had been so down. Now some woman was paying attention to him, and actually was telling him that she had always liked him.
Darlene Mitchell sent a letter to the printer ID I had sent in the letter to Richard, saying the following:
Dear Ghost Writer,
This has been the most exciting thing that’s happened in the warehouse in a long time. We await your messages. Dick is really trying hard to figure this out, and if you don’t give him a little hint, his little old brains are going to get fried.
He also requests that you send his messages to his printer only, that way I won’t be able to send my message back. He takes all the fun out of everything. P)24 is his number, and if you can’t get a response out of him, I’ll be glad to put my two cents in.
I’m sure Dick would like to see you too. Maybe we can get him headed in your direction, if you tell me where that is.
So, long, see you in the funny papers.
<end of message>
On Thursday Richard called me and asked me to come over to the warehouse. He showed me the letter he had received that day. He said he was too excited. He just had to find out who it was that was sending him these letters. He said that since I knew everything there was to know about computers (a slight exaggeration), he asked me to see if I could find out where the letters were coming from.
I told him I would do what I could to see if I could track down who was sending the letters. On the way home that day, he asked me if I had any luck. I told him I was still looking into it. I told him I thought there might be a way to find a log somewhere that would tell me.
So, after lunch on Friday I walked over to the warehouse. When I entered, I signaled to Richard that I wanted to talk to him. — Remember. Richard and I had developed facial signals while carpooling with Bud Schoonover so that all we had to do was glance at each other and we instantly knew what each other was saying…
Richard and I stepped outside of the warehouse where we could be alone. He asked me if I had found the person sending him the letters. I told him I had (I knew I had to do this right or I would lose a good friend, so I said), “Yes. I have.”
I could see the look of excitement in his face. So I looked straight at him and I said, “I have been sending these letters to you.” He was stunned. He said, “What?” I said, “Richard. I have been sending them to you.”
I could see that he was very disappointed. After all. No two people could read each other’s expressions better than me and Richard. We practiced them every day. The corners of his mouth went down. The middle went up. Edges of the eyes went down. Eyes began to water. Yep. He was disappointed to say the least.
I told him I was sorry to get his hopes up. I put on the saddest look I could muster. Inside I wasn’t so sad. Actually I was pretty happy. I knew this was a tough moment for Richard, but he had spent an entire week flying high. For the first time in a long time, Richard had hope. A couple of hours of disappointment was well worth this past week.
I patted him on the back and he turned to walk back into the warehouse despondent. I went back to the electric shop.
As for my part, I continued sending Dick Dale printed messages from time to time. Just goofy messages like the following:
Sometimes when I type letters I find that the words I use are not always the typical type that I would use if I wrote a letter. The letters that I make when I write a letter aren’t the type of letters that I use when I type a letter. When I write a letter, the letters in the words are sometimes hard to distinguish, but the letters I type when i’m typing a letter are the type of letters that stand out clearly and uniformly. I can’t really say that when I type I’m right, or when I write I’m right, because I usually type a different type of letter than I write when I’m writing a letter. I typically use a different type of words when I’m typing than I use when I’m writing, so I really can’t say that writing is right when a typical typed letter is just as right as writing. That is just the type of person I am.
After a few more days, Darlene Mitchell and Dick Dale began sending me letters indicating that the warehouse workers had been taken hostage, and they had a list of hostage demands. I would write back to them. The hostage letters and my replies would make up an entire blog post just by themselves.
So, what followed this episode? Well. Within a few weeks Dick Dale had attended an event at the Presbyterian Church in Ponca City where he met a very nice woman, Jill Cowan. He began dating her, and within the year they were married on November 13, 1988.
I like to think that I had given him the kick in the pants that he needed at the time that he needed it. For that one week where he had hope, he believed that someone else really cared for him (which I really did, just not in the way he was thinking). If he could believe that, then maybe it could really be true, even if in this case it turned out to only be one of his best friends.
I know that Dick Dale lived happily ever after. As I mentioned earlier, I wrote a post about Dick Dale about a time when I gave a Christmas present to Dick Dale, Christmas 1983. Well. as it turned out, my friend Richard was presented to Saint Peter at the gates of Heaven 25 years later on Christmas Day, 2008, 20 happy years after his marriage to Jill. I don’t really miss him. He is always with me in my heart to this day.
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.
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.
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.
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.
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.
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.
Comments from the original post:
A year after I joined the electricians in the electric shop, Howard Chumbley became my foreman. One day when we were talking about going to the old Osage Plant up the road to clean up a PCB (Polychlorinated Biphenyls) spill, he explained that “In His Day” they used to clean their tools in a vat of transformer oil that was full of PCBs. I remember him telling us that it was normal for him to be up to his elbows in the stuff. They never thought it might be harmful. Now we were getting ready to go up to the old plant to clean up a small spill and I was going to have to suit up in a special hazardous waste suit. I wrote about our experience in the post: “Pioneers of Power Plant Fame Finally Find Peace“.
Now we know about the hazard of developing cancer by having PCBs in your system. Today we know a lot of things we didn’t know back then. We know that Asbestos causes Mesothelioma. We know that Chlorofluorocarbons (CFC) destroy the ozone layer. We know that Twinkies are one of the few foods that will be around after a nuclear holocaust.
Years before I became an electrician, the Electric Company had stopped using oil with PCBs. There was still an effort to clean it up from the older plants. At the new coal-fired power plant in north central Oklahoma, we didn’t have a problem with PCBs. We had other problems. Some of which we didn’t know about (well, we knew something, just not so much) at the time.
A very prominent responsibility of mechanics and electricians was to clean oily equipment. Pumps and motors, breakers, fans, mills. All kinds of equipment. Almost everything was lubricated one way or another with oil. Solvent was used to remove the oil when the equipment needed to be cleaned.
We had a standard kind of solvent at our plant. I believe it was called “Standard Solvent 350”. See…. It was a Standard solvent. Even had the word Standard in the name. One of the key ingredients of this standard solvent is a solvent known as “Stoddard Solvent”. This solvent worked real good when cleaning up equipment like motors and pumps and other oily equipment. Many times we were “Up to our elbows” in this solvent.
We had a barrel in the corner of the electric shop close to the door to the main switchgear where we could put a motor and scrub it clean while solvent poured out of a flexible nozzle on the motor, your shirt, your pants, your work boots, and the floor. Some days during overhauls when we would work cleaning motors for 10 hours each day, I would come home from work drenched in solvent. My wife would make me take my clothes off in the utility room where I could put them directly into the washing machine where Oxydol could go to work on it right away.
When Ted Riddle and I were working for Willard Stark on an overhaul at the gas plant outside Mustang Oklahoma during the spring of 1986, Willard said one day that he wanted to show us something. I explained Willard’s situation at the plant in a post called “Working Power Plant Wonders with Willard Stark“.
He was a good example of what I would call a “Contrarian.” That is, he seemed to buck the system often. He thought outside the box a lot. I realized this right way when we would listen to Paul Harvey on the radio during lunch. Every time Paul Harvey would say, “…Noon News and Comment” Willard would always finish the sentence by saying, “Mostly Comment.” I figured then that he had to be a contrarian, because who would ever think that Paul Harvey wasn’t the best person in the world to bring the News to our private little power plant world.
So, when Willard said he was wanted us to see something “with our own eyes”, I figured this was going to be something good. Probably some kind of secret place where you could hide and take a nap if the day wore on too long, or something like that. Well… It didn’t turn out to be that kind of “something”, but it was something.
Willard took a small metal pan and put some Stoddard Solvent in it. The old gas plant used straight Stoddard Solvent, unlike the more sophisticated Coal-fired plant where Ted Riddle and I normally worked. We walked out into the turbine-generator (T-G) floor. He placed the pan of solvent on the floor, took a WypAll (which is a strong paper rag) and dropped it into the pan:
Then he bent down and with his lighter, he lit the WypAll on fire. We watched as the flames grew higher and higher. Willard watched our expressions. We had been under the understanding that Solvent was not flammable. He explained that technically, Stoddard Solvent is not considered “Flammable”, but it is considered “Combustible”. Combustible means that it burns.
Stoddard Solvent doesn’t ignite fast enough to be considered “Flammable”. At least that’s the way Willard explained it to us. Willard said he wanted us to be aware of this fact when we have our bodies all soaked in solvent, that if we were to catch on fire for some reason, we were going to go up in flames just like that WypAll. We both appreciated the advice.
I didn’t begin this post expecting to say that much about Stoddard Solvent, but just in case you were really wondering what it is, maybe this picture will explain it to you:
I hope that cleared it up for you. You have to wonder why they put that “Oh Oh” down there at the bottom. Almost as if something is supposed to go wrong.
The solvent I really wanted to talk about was one that was used more exclusively in the electric shop. It is called Trichloroethylene 1.1.1. You see, a lot of equipment that we cleaned in the electric shop needed to be cleaned spotless. Solvent 350 would leave a film when it dried. So, in the electric shop when we needed to clean something with electric contacts we would use something called “Electro Contact Cleaner”:
This was very expensive compared to the regular solvent. So, I was surprised when Ben Davis and I first went on an overhaul in Muskogee, and they had this exact same contact cleaner in 55 gallon barrels:
I remember John Manning showing us a few of these barrels that they had ordered for the overhaul. I think my jaw dropped. By my calculation, one barrel like this would cost over $3,000.00. I figured if it was in cans, it would have cost three times that amount. The advantage of using Contact cleaner was that it dried clean. It didn’t leave a residue.
Trichloroethylene 1.1.1 was like that. It didn’t leave a residue when it dried. I think this will become obvious to you when you see what it really is:
You can see right off the bat that this is going to dry clean… I mean…. it’s obvious… right? I think the CLs on three of the corners indicate that it “Cleans” 3 times better than other solvents.
Anyway. This stuff evaporated quickly so when you were up to your elbows in this solvent, it felt cool because it would evaporate causing a cooling effect. It had a very peculiar smell. It also made you feel a little dizzy when you were using it. Especially when you had to breathe in a lot of it in a confined area. Having fans blowing on you seemed to make it worse, because it would increase the evaporation rate filling the air with more solvent.
It was known at the time that Trichloroethylene would destroy your liver when it gets into your blood stream. There was no quicker way of injecting the solvent into your blood stream than by inhaling it. Finally OSHA decided that this solvent was no longer safe to be used in a plant setting. It could only be used in small quantities like “White Out”.
Gee… Who remembers White Out?
The last time I heard about white out was in a blonde joke about someone using white out on the computer monitor. Who types anymore on a typewriter? I think anyone today that would choose to type on a typewriter would be the type of person that would prefer a typewriter eraser over white out.
I take that back. The last time I heard about White Out was on a show like 60 Minutes where they were showing young kids in Panama or another Central American country being hooked on tubs of White Out. They would sit around all day taking quick whiffs from a tub of White Out. — Why? Because it contained Trichloroethylene and it would give you a buzz.
My dad, a Veterinary professor at Oklahoma State University had told me about the dangers of Trichloroethylene around the time I told him about Bill McAlister using WD-40 on his elbows to ease the pain of his arthritis. Sonny Karcher had asked me to talk to my dad about it to see if he knew why WD-40 would help Arthritis.
My father (I’ll call him Father in this paragraph, because in this paragraph, he’s being more “sophisticated”) told me that WD-40 had the same chemical in it that Veterinarians used on horses to help their joints when they hurt. Then he warned me that the solvent in WD-40 soaks right into your skin and when it does it carries other toxic chemicals into your body than just the arthritis lineament. So, he told me to tell Sonny not to use it often.
So, anyway, we had to find a replacement for Trichloroethylene. Tom Gibson and Bill Bennett went to work ordering samples of other kinds of solvents that salesmen were saying would be a good replacement. One of the first that we tried was called Orange Solvent. It had a real nice Orange smell. Sort of like drinking Tang.
It had a couple of problems. First, I would be more inclined to drink it since it smelled so good, and I was a fan of Tang at the time.
The second problem with the Orange Solvent was that it didn’t seem to clean very well. We were used to something cutting the oil and contact grease quickly. the Orange Solvent didn’t cut the mustard (so to speak).
One day during overhaul at our plant, Bill Bennett gave us a barrel of some new kind of solvent. It was supposed to be comparable in it’s cleaning ability to Trichloroethylene (could you imagine Red Skelton trying to say that word?)
Bill wanted Andy Tubbs and me (I know! It seems as if it should be “Andy Tubbs and I”, but “me” is the correct way to say it) to use the new solvent on the main power transformer main bus connectors. They are normally covered with No-Ox Grease so this would be a good test.
So, Andy and I carried the large extension ladder out to the Unit 1 Main Power Transformer and leaned it up against the back side (the transformer’s backside, not ours). We climbed up to the open hatchways and crawled in. We hung a small yellow blower in the doorway to blow fresh air on us.
Andy and I had everything setup and we were ready to work. We both just fit in the small area with the large bus work between us. We began using our rags soaked in the new solvent on the silver plated bus. I don’t remember how well the solvent cleaned the bus. I just remember thinking that this solvent sure did evaporate quickly. Especially with the blower fan right next to us.
I also remember looking over at Andy crouched across from me. He was looking down at the bus. Then his entire body seemed to swivel around as if he was on some kind of swing which caused him to tilt up the side of the enclosure. I watched his face, and he seemed to be saying something to me, only I couldn’t make it out.
I think I said something like “Huh?” Then about that time all kinds of brightly lit flowers were circling around my head and my arms seemed to be floating in front of me. I heard Andy say with a slur, “We butter git outta here…” His voice sounded like it was in a pipe…. Well, we sort of were sitting in a pipe… He started to move toward the hatchway.
I remember briefly thinking that I was just fine enjoying the interesting scenery. By now there were bright lights streaming toward me from all sides. Then I thought. “No. I better leave.” So, I struggled to pull myself into the hatchway. It was big enough that we could both pull ourselves out together.
I began climbing down the ladder head first. It was about 15 feet to the ground. I was completely out of the hatch with my body completely upside down on the ladder before I decided that it would be better if I turned over and went down feet first. Somehow I managed to swing my feet down and around without falling off the ladder. I think Andy was pretty much in the same predicament as I was.
Once we were on the ground, we hobbled into the electric shop and sat down. We told Bill Bennett that this was not a good solvent to use. I don’t even want to remember what the name of the solvent was. If I mentioned it, someone may put it in some tubs of white out and sell it to kids in Panama, because Trichloroethylene had nothing on this.
I suppose we finally found a replacement solvent. Though, I don’t remember what it was. All I do know is that it was quite an adventure trying to find one. Maybe we just used a lot of Electro contact cleaner after that.
Like Howard Chumbley, who told stories about being up to his elbows in transformer oil made with PCBs, I can now tell my fellow teammates at work, “Yeah. I remember the days when we were up to our elbows in Trichloroethylene. Never gave it a second thought.” Only, their reaction would be a little different than ours were in the electric shop office. They might raise their eyes up from their computer monitors and look across the cubicle at me for a moment. Then give me a look like “there goes that crazy old guy that used to work in a power plant again. Hasn’t he told us that story about 50 times already?” Well…. That solvent and stuff. It makes you forget things…. I can’t remember what I have already said.

As a young novice Power Plant Summer Help, I had watched seasoned Power Plant Men measure the distance between two points by walking between them and multiplying the number of steps by three. At first I wondered how they could be sure that their strides were all exactly three feet apart. Because the end result of these actions usually came out pretty close to their estimate, over time I began to think that the length of the stride of any respectable Power Plant Man must naturally be three feet.
So, one day when I was working on going to pull a cable from one manhole to the next, I decided I wanted to know the distance before I pulled a lot of cable off of the cable reel. So, I remember that I grabbed the tape measure out of my tool bucket and began walking at as normal of a gait as I could.
I thought if I measured the first step, or even the last step I took that it would somehow be a different size because I wasn’t moving at my normal speed. So. I figured I would surprise myself by just stopping at some random step as I walked between the two manholes.
I don’t know if anyone was watching me as I stood out in the field just north of the two smokestacks, if they were watching me, then they would have seen me pause and stand still for a moment looking down. Start messing around with my feet. Then take a few more steps. Pause once more and do the same thing.
What I was doing was stopping in the middle of my stride when I had just put a foot down, before I lifted the other foot and with my Stanley metal tape measure, I was measuring the distance from the back of one heel to the back of the other heel.
I can’t say that I was too disappointed to find that my stride was not exactly three feet. I hadn’t figured I was completely Power Plant Man material anyway. It turned out to be exactly 30 inches. Or two and a half feet. So, I realized I was about 3/4 Power Plant Man measured by my stride.
I found that I could easily walk between two points and measure the distance with great accuracy by multiplying the number of steps by two and a half feet. With great knowledge comes great responsibility…. or…um… something like that. Hence the story about how enough was not quite enough.
During the spring of 1992 I was tasked with running telephone cable to various points around the plant. We were going to begin installing a new computer network known as the “Ethernet”. When I first heard the name, I thought they were referring to something in space, where it used to be the belief that there was an area called the “Ether”. But as it turned out, it was the regular network that is still in use today.
Dennis Dunkelgod from Oklahoma City had come to the plant with a bunch of drawing much like they did a few years earlier when they wanted me to install the Dumb Terminals all over the place. (See Post “Working Smarter with Power Plant Dumb Terminals“). This time the diagrams included places where PCs were going to be placed. And where the network server was going to be setup. This required much better quality wiring than the dumb terminals.
So, Dennis saw to it that I had 1/2 mile of 100 pair telephone cable to run from the main plant up to the coalyard. Along with the cable came a box of 25-pair punchdown blocks. I’m sure you’ve seen punchdown blocks in movies when someone is tapping into a phone line, so they go up to these punchdown blocks and hook their handset up to the wires and listen in.
One of the places where I needed to place a number of computers was in the warehouse and the warehouse office. There were no good phone lines running to this building. There were barely enough to take care of the phones that were in the office at the time. So, I needed to figure out how to run the telephone cable to the warehouse which was the southern-most building in the main plant grounds.
Across the drive from the warehouse was the garage. When I looked at the phone panel in the garage, this looked like a good place to tap into the phone system. There were two 25 pair blocks in this building for only one phone. Enough for all the computers in the garage and the warehouse.
All I needed to do now was figure out how to pull a 50 pair telephone cable from the garage over to the warehouse. After looking for the conduit that brought the existing cable into the garage, I was able to determine how it went over to a hand hole at the north corner of the building and then over to a manhole not far away.
A hand hole was a shallow hole in the ground that has buried conduit coming into it. Our handholes had a large piece of concrete covering it.
When I looked at the handhole I suddenly remembered that in during the week of March 21, 1981 I had visited the Power Plant to pick up my application to apply for working as a summer help for my 3rd summer. I was wearing a beard that day when I arrived. While I was in college, I usually wore a beard in the winter to keep my face warm because I rode my bike a lot, and it helped keep my face warm.
I had my friend Tim Flowers with me that day because he was going to apply to be a pre-novice Power Plant Man and work as a summer help also that summer. It was snowing that day and it was almost 4:30pm. Quittin’ Time by the time I had said hello to the many Power Plant Men that I hadn’t seen since the previous summer.
We were heading back out to the parking lot when I heard someone hollering at me. I looked over toward the garage and there was Jim Heflin sitting on a backhoe digging a ditch. He had turned off the backhoe so that I could hear him yelling at me.
The Backhoe that Jim was on didn’t have a cab on it. He was all bundled up trying to keep warm. I believe when he pulled down his face warmer, he too was wearing a beard. He said that before he could go home that day he had to finish this rush job to dig a ditch all around the back and side of the garage.
When I returned the next summer Jim asked me if I remembered him digging the ditch in the snow that day in March. I told him I did. Then he said, “Come here.” We walked around the side of the garage, and sure enough. There was the ditch still open leading around the side and back of the garage. He said, “It was such a rush job I had to stay out in the snow digging this ditch before I could go home, and it has been left untouched since then.
The reason I bring this up, was because the ditch he had been digging was for the conduit that went from the handhole around the back of the garage and over to the warehouse. Later that summer the Construction crew from downtown came out to the plant and laid the conduit in the ditch and covered it back up. So, I knew how the cable needed to run from handhole to handhole over to the warehouse. Oh. Before I forget. Here is a picture of Jim Heflin with a beard:
So, back to figuring out how to get the cable to that warehouse. I measured how far it was from the punch down blocks to where it went down into the ground. From there I walked with my normal gait (which I knew was exactly 30 inches – remember?) counting my steps.
I measured how many steps it was to each handhole and over to the warehouse. where the conduit came up out of the ground and went into the warehouse. In this manner I calculated that I needed 775 feet exactly.
I figured I didn’t want to use the 100 pair cable. That was a lot more cable than we would ever need for this job, so I went up to Bill Bennett’s office and told him that I needed 775 feet of 50-pair telephone cable to go from the garage to the warehouse. He said that he would order some.
I don’t remember what time it was when I woke up in a cold sweat in the middle of the night thinking that the length of cable was just going to reach the telephone junction box, and not enough to comfortably reach the punch down blocks halfway up the junction box. So, when I arrived at work in the morning I went straight to Bill’s office and told him that I should have ordered at least 800 feet of cable instead of 775, just to be safe. Bill told me that he had already placed the order for 775 feet. It was too late to change it.
I thought to myself… surely when you order 775 feet of cable they will send some reasonable amount, like 1000 feet. Would they really cut it off at 775 feet exactly. So, I told myself it would be all right.
Sure enough. a couple of days later a reel of 50 pair telephone cable showed up in the electric shop. In big numbers written on the side of the real in red marker were the numbers “775 ft.” Oh geez.
Ok. Somehow I was going to have to make this work. Cross my fingers that maybe my stride was only 28 and a half inches now instead of 30 inches and I had measured it longer than it really was.
So, I pulled the cable from the garage, through the manholes over to the warehouse. In order to pull it from the last handhole into the junction box in the warehouse I had strapped some mule tape to it that I had strung earlier through the conduit using a fish tape. I remember going inside and beginning to pull the last bit of the cable to the junction box hoping to see the end of the cable come up out the conduit.
As I was pulling the cable, I could feel the cable beginning to bind up as it was tightening up in the last handhole. I was still only holding mule tape when I couldn’t pull anymore. Meaning that I didn’t have any cable yet.
So, I went back to the garage and pushed as much cable into the conduit that I could and still punch down the wires on the punchdown block. I even lowered the punchdown block in the junction box hoping that the extra foot would help. Then I went to each handhole and pulled the cable from the garage in the direction of the warehouse until it was as tight around the corners as it would go.
I had managed to pull an extra 2 feet or so into the last handhole. Now all I had left was to go into the warehouse and pull the mule tape to see if the cable would reach the junction box. — Suspense. Yeah. I know.
When I pulled the last 2 feet of cable from the handhole into the junction box, the end of the cable came out. But only about 1 foot of cable was in the junction box. A punchdown block is about 1 foot long.
So, in order to be able to punch the telephone cable down on the punch down block, I had to put the punchdown block at the bottom of the junction box, right where the cable came out of the conduit. On both ends of the cable, I never had to cut one inch of cable from either end. After making sure I had every inch of cable pulled tight through every handhole, I punched down both ends using the handy dandy Telephone wire punchdown tool.
I told myself that from now on, I was always going to throw in a couple hundred extra feet whenever someone asks me how much cable I need. That was too close! You would have thought I learned my lesson.
Now, 22 years later, I still have the same problem as a business analyst at Dell. Part of my job is estimating how long it is going to take to complete various parts of a project. I always make the same mistake and try to over-analyze it so that I can give a really accurate value. The problem is, that I don’t take into account that things take longer than you would think because of factors out of our control.
My project managers know me well enough to take the number that I give them and add a decent amount of time to my estimates. I even tell them that they should because I always underestimate the time. I always estimate how long it would take me to do it personally and I’m not usually the person that is actually writing the code.
Through the last 12 and a half years while working at Dell, I have never missed a go-live date. Oh. Just like this story, we finish on time, but with little or no time to spare. We are always up to the wire. Beginning right when I said we would and ending on the date we planned. Believe me. Just as I pulled every inch of slack out of that cable that day, we end up doing the same with the progress of our projects.
So, I guess I still haven’t learned to properly pad my estimates to reduce the risk of falling short. I think it has something to do with my personality and the way everything has to be mathematically calculated in my head.

Ken Couri was the plant safety guru long before Randy Dailey showed up on April 16, 1984. Ken gave us our yearly Safety training on such things as first aid and CPR. When Randy came on the scene, our yearly safety training shifted into overdrive! Ken was the one that tested my driving when we took the Defensive Driving Course the summer of 1981 during my third summer as a summer help.
I remember that Ken climbed into the pickup truck parked outside the electric shop as I walked around to the driver side. I thought. This will be a cinch. I’m a great driver. I should come out of this with flying colors. I talked about this class in the post “Power Plant Safety is Job Number One“.
I had done my “Circle for Safety” by walking around the truck to make sure there weren’t any obstacles in the way. Which, by the way, is why AT&T trucks used to stick an orange cone at the back and front corner of their truck (maybe they still do. I haven’t noticed one lately). When an AT&T worker goes to pick up the orange cones, it forces them to look in front and behind the truck to make sure that there isn’t an obstacle behind or in front of it that they might hit when they leave the parking space.
I thought, right off the bat, I must really be impressing Ken Couri. Ken was a heavy equipment operator from the coalyard. He was a heavy equipment operator in more ways than one. In fact, I always thought of him as a gentle giant. Anyway, I thought, he probably hadn’t seen anyone do a circle for safety as geometrically circular as I was doing it. I had calculated the radius from the center of the truck to the front bumpers, added two feet and began my circle for safety checking both the front and back of the truck for obstacles. All clear.
I climbed into the truck, and without hesitation, grabbed my seat belt and strapped myself in. Smiling, I looked over at Ken, who was looking down at his checklist, apparently not paying any attention to me. Hmmm. Ok. Maybe he would be impressed by the way I backed out of the parking space.
I always had the habit of turning around and looking behind me as I backed out. So, I did just that. I carefully backed the truck out of the space while observing everything through the back window, momentarily glancing back to the front to make sure the truck didn’t strike anything as the truck pivoted around. Confident that I had done everything right, I noticed that Ken hadn’t looked up or written anything on the checklist.
He told me where to drive, and I put the truck in drive and headed in that direction. That is when I looked up at the rear view mirror for the first time. I suddenly realized I had made a grave error. I watched as Ken’s hand that held the pencil worked its way up the sheet to a particular checkbox and marked it.
You see, while I was busy creating my perfect Circle for Safety, Ken had climbed into the pickup and reached up and knocked the rear view mirror down so that it was way out of whack. I stopped the truck for a moment as I adjusted the mirror knowing full well that I was supposed to have done that long before I had put the truck in reverse. Well, that was that. No perfect score for me, and I was just beginning the test.
I didn’t know whether to feel bad about that, or to laugh about the way that Ken just sat there with no expression on his face as he checked the box that indicated that I hadn’t checked my rear view mirror before shifting into reverse as we had learned in the videos. I think I was so ashamed about not checking my rear view mirror before shifting into reverse so much that I didn’t even tell my best friend, Tim Flowers on the way home that day. Actually I was so disappointed with myself that this is the first time I have revealed this secret failure to anyone (other than Ken Couri of course, God rest his soul).
The one thing I remember most about Ken Couri during the yearly safety meetings was that he would tell us the story about Annie, who was our CPR dummy. Annie was a drowning victim in Paris France in the Seine river. Her real identity wasn’t known, but her drowning was considered such a tragedy, because someone so lovely as her had apparently committed suicide, and no one was around to save her.
Years later, a guy named Asmund Laerdal in Norway used her image to create the CPR mannequins known as Rescue Annie.
I am sort of an emotional person at the weirdest times, so whenever we had to practice CPR on Annie, I would get all choked up while trying not to let my coworkers see that I was having difficulty with performing CPR on a mannequin of a real person that had died from a real drowning back in the 1800’s. The only comfort I had was knowing that, as Ken Couri pointed out and Anna Edwards said in 2011: Her enigmatic smile is known to millions around the world and she has been kissed billions of times. (Read more: http://www.dailymail.co.uk/news/article-1393184/How-girl-drowned-Paris-kissed-face-time.html#ixzz2xJxJIJNj).
Once every year we would receive First Aid training from Ken and Randy. Each time we would hear the same stories about Safety and their importance. Randy, who had been a medic in the army had a full array of sayings (maybe the Power Plant men can add a comment to the post with some of his phrases). I wish I could remember them all at the same time.
Unfortunately they only come to me when an appropriate occasion arises. Like I see some unsafe act, or a possible situation where a tragedy could happen like the ones that Randy would describe. I remember his speech about the ABCs that you perform when you run across someone that is unconscious. You first “Assess” the situation. Then you check for “Breathing”, then you check their “Circulation”. He would always end by saying that “A weak pulse is hard to find.”
He would demonstrate this by tapping the dummy on the shoulder as an example and say, “Hey. Are you all right? You don’t want to perform CPR on someone that is only taking a nap in the park.” Then he would turn to one of us and say, “Call 911!” That was called, “implementing the EMS system. EMS stood for the “Emergency Medical System”. Then he would place his ear close to the mouth of the dummy while he was checking the pulse on the neck. He would repeat, “A week pulse is hard to find.”
In the past I may have described Randy Dailey as someone that would remind you of Barney Fife from the Andy Griffith Show… Maybe I haven’t, but he sort of does sometimes. You tell me.
Here is Randy Dailey:
Randy may occasionally remind a novice of Barney Fife, but to the experienced Power Plant Man, just looking at him and a Power Plant Man automatically thinks “Safety”! During the “We’ve Got the Power Program” (See the post: “Power Plant “We’ve Got the Power” Program) Randy Dailey invented a special pen that you could put in your handy dandy pocket protector worn by most respectable Power Plant Men that would beep at you if you were bent over too far and were putting yourself at risk of a back injury.
Randy had a lot of compassion as he trained us on safety. You could tell that he had an agenda, and that was to make sure that all of us came out of the class knowing how to provide the best first aid possible to our fellow Power Plant Men as possible. When he spoke to us about dressing a wound and performing CPR on someone who had no pulse, he never cracked a joke (well, except when he showed us how to create a diaper out of the triangular bandage).
He was serious about safety, and we carried that with us when we left the class. We knew that Randy had seen the worst of the worst during his life. I remember Monday, May 8 of 1989 we had just begun our safety training course. Randy may not have been thinking about the fact that he was turning 40 that day, but for some reason I had always known his birthday.
He told us a tragic story of a 4th of July celebration that he had attended. The topic was knowing when “not to do CPR”. I think he was in Arkansas. He was sitting in the bleachers watching the celebration when suddenly something went terribly wrong. As the crowd was watching the large explosions overhead creating huge balls of red and green and blue, there was suddenly an explosion on the ground that was unexpected.
A piece of metal shot out of the area where the fireworks were being ignited and flew into the crowd. I think he said it was a young lady that was struck in the head by a metal plate that cut the top of her head completely off just above the eyebrows. Randy went on to explain that in a case like this, CPR would obviously be useless, so use your common sense when assessing your surroundings.
Each year when Randy would tell this story, I would feel this sick feeling in my stomach, and I would taste this strange taste of blood in my mouth as the corners of my mouth would go down in disgust. This was an obvious tragedy that Randy witnessed, and the feelings I had were not so much about the person that was struck as they were instantly killed. It was because behind the stalwart face of Randy, while he told this story I could see the tremendous sorrow that he felt while recounting this story to us.
I knew, and I believe we all knew, that the reason that Randy was such a great Safety instructor was because he really and truly wanted to save lives. That was his ultimate goal. He would begin his mouth-to-mouth resuscitation training by quoting from the Bible. It was from Kings 4:34. He would say that mouth-to-mouth is found in the Bible. Then he would quote word-for-word from the book about Elisha saying:
“And he went up, and lay upon the child, and put his mouth upon his mouth, and his eyes upon his eyes, and his hands upon his hands: and he stretched himself upon the child; and the flesh of the child waxed warm.”
Randy pointed out, this is Mouth-to-mouth resuscitation in the Old Testament folks! So, when a situation arises, don’t be worried about germs and the like. Do what is necessary to save a life! Again I could see his mind flashing back to some tragedy that drove Randy on to make sure we were properly trained in First Aid and CPR.
Randy didn’t teach us Safety to gain “Bonus Points” from management as some pseudo-Power Plant Men did. Randy, from the day he came to the plant in May 8, 1984 (What a birthday present to become a Power Plant Man on your Birthday!) until the day I left on August 16, 2001, was a true hero to me. I don’t know if he ever served in combat. I don’t know if he ever received one little stripe or medal on his uniform in the Army. What I do know is that to this day I am eternally grateful that I have had the opportunity to meet one of the most remarkable souls of our time the day Randy Dailey showed up at the Power Plant. I have always been certain that God himself sent Randy to administer his Safety Wisdom to the Power Plant Men at the Coal-fired Power Plant in North Central Oklahoma! Randy continued to bless all of us year after year.

In an earlier post titled “Power Plant We’ve Got the Power Program” I explained how in 1990 we broke up into teams at the coal-fired Power Plant in North Central Oklahoma to find ways to save the Electric Company money. Before we were actually able to turn in our first set of ideas, we had a month or more to prepare those ideas and to turn them into proposals. During this time, and throughout the entire “We’ve Got the Power” program, teams who wanted to succeed and outdo the other teams became very secretive. Our team was definitely that way. We had secret experiments going on throughout the plant, and we didn’t want other teams to even know what areas we were investigating.
As the program progressed, a certain level of stress developed between teams. In a later post I will tell a story about how this level of stress led to a situation of suspicion and eventually even animosity. This post will not go into that situation. Instead I want to explain what our team did to try to alleviate some of the stress by devising a special “Power Plant Joke” that we played on the rest of the Power Plant Men (and Women).
There were some teams that had setup some experiments that they were running to see if their ideas may save the company money. Our team had several experiments running throughout the beginning months. All of which we carefully hid from prying eyes. We were proud of our stealthiness. Sneaking around, making sure we weren’t being followed when we went to take readings from our carefully hidden recorders and other devices.
Charles Foster, Scott Hubbard and I were sitting in the electric shop office discussing the stress level that had permeated the plant, and we thought we could take advantage of the stress by setting up a “We’ve Got The Power” Experiment out in the open that would be obvious to anyone that walked by. Only it would be a fake experiment designed to play a joke on the unsuspecting Power Plant Man.
Here is what we did….
Right outside the electric shop in the Turbine Generator basement there is a water fountain. We placed a hazard waste barrel a few feet away from the water fountain. Like this:
Then we mounted a junction box on the wall a few feet above the chemical waste barrel and a little to the right.
We turned the junction box so that the hinge was on the top, allowing the door to fall closed naturally. This was an important part of the setup to allow for the joke to automatically reset each time it was operated.
We ran some copper tubing from the water fountain water line over to the box. Then another copper line came out the bottom of the box and into the barrel. Next to that copper tube, another smaller copper tube came out of the bottom of the box and just bent toward the front of the box. It was not noticeable. We had a plastic hose coming out of the barrel and over to the drain next to the water fountain. Then we put Yellow Barrier Tape around the entire setup.
We tied Caution tags to the Barrier tape that said “We’ve Got the Power Experiment” Do not enter! I signed the tags.
There was an electric conduit running up from the junction box, that went up and into the wall about 6 feet above the junction box. So, this looked like a legitimate experiment going on, but for the life of anyone, no one would be able to tell what it was doing. — Mainly because it wasn’t doing anything….. At least not until someone went to investigate it.
So. Here is what would happen….
Employees would walk by and see the barrier tape with the hazardous waste barrel and the hoses and water lines coming from the back of the water fountain, with a junction box above it that was not completely closed. The door to the junction box was down, but not screwed closed. Conduit was going into the box, which meant that something electrical was probably inside Maybe a solenoid or something that was controlling the experiment.
They would read the Caution Tag that explained that this was a “We’ve Got the Power” experiment, and it would pique (pronounced “peak”) their curiosity enough that they couldn’t help but investigate it to see what was really going on.
So, what would invariably happen, was that someone would enter the area that was barrier taped off, and open the junction box to see what was inside. When they lifted the lid, they would find that they were instantly being soaked with water that would spray out of a small copper line pointing right at them directly under the junction box. At the same time, an alarm would go off above them behind the wall right above the electric shop office. It was very loud. A counter inside the junction box would register an “intruder’ had just opened the box.
So, as we would be sitting there during lunch, we would suddenly hear the alarm go off, and we could dart out the door to the Turbine Generator basement to find a drenched Power Plant Man. They were usually amused that they had fallen into the trap. I say usually, because I have the feeling that one particular person who found himself violating the barrier tape and getting soaked didn’t act too cordial about it. I’ll get to him later.
As I said, inside the box was a counter. It counted how many times the box had been opened and sprayed someone with water. So, we could go inspect it in the morning and we would know if anyone had looked at it while we were gone.
After the experiment had been there about a week, an overhaul began where Power Plant Men from different plants came to our plant to perform the overhaul. The plant would shut off one of the units and we would take it apart, and put it back together again fixing problems along the way (well. maybe not quite that drastic. It was a time to fix things that couldn’t be maintained or repaired while the unit was running).
So, the Power Plant Men at our plant, who by that time all knew about the bogus experiment just outside the electric shop, would bring unsuspecting Power Plant Men from other plants over to the see the “We’ve Got the Power” experiment going on in the hopes of seeing them get sprayed with water. So, a new round of alarms were going off during that time.
Eventually, when people had heard about the experiment, and knew that it was spraying people, they would approach the experiment with caution. When they opened the lid of the junction box, they would stand next to it against the wall in order to not get wet. The spray pattern from the crimped copper line was fairly wide, so you would have to stand practically against the wall next to the box in order to stay dry.
So, this was when we implemented Phase 2 of the experiment. — Yeah. It’s the second phase of many Power Plant Jokes that usually make the joke a much bigger success than the first phase. For instance, I have written a post about the “Psychological Profile of a Control Room Operator” in which I had played a joke on Gene Day, where after a week of preparing him for the final joke, I had coaxed him to look over my shoulder, only to have him read that according to his psychological profile, he was the type of person that would look over your shoulder and read your private material.
That would be a good joke in itself, but when Gene Day read that and began choking the life out of me, I pointed out to him the final statement in Gene Day’s profile which stated that he tends to choke people who try to help him by creating Psychological profiles of him. This second part of the joke is what really completes the joke and makes it a real success. The first part just makes it funny.
So, here is how we modified the experiment for Phase 2…. The nozzle that sprayed the employee actually came out the bottom of the box and elbowed to point toward the front of the box. So, what we did was we took a file and filed a tiny notch in the side of the copper tubing just below the junction box just above the elbow. The notch was on the side of the copper tube, and it was deep enough of a notch to make a little hole in the side of the copper line.
So, then, if someone was standing to the only side they could stand next to the box and the barrel and they opened up the lid of the Junction Box to show someone how the experiment worked, they wouldn’t notice right away, but a small stream of water would be spraying on their pants in just the appropriate location to make it look like the person had just pee’ed their pants.
Right when we had finished modifying the experiment for Phase 2, Howard Chumbley walked into the electric shop. He was a retired Electric Foreman, that I have written about in the post “Pioneers of Power Plant Fame Finally Find Peace“. He had come to visit the plant that day because there was going to be a Men’s Club lunch and he wanted to come and see some other old codgers that he used to work with that liked to attend the Men’s Club dinners. He always wanted to see us of course as well.
So, we told him about the “We’ve Got The Power” Joke Experiment just outside the electric shop that sprayed water on people. Of course, he wanted to see it, so we took him out and let him observe it. We explained that when you open the lid, an alarm goes off, the counter toggles and water sprays out of that little nozzle sticking out at the bottom. We told him he could try it if he wanted to see how it worked.
So, he climbed under the barrier tape and walked around the side of the junction box that didn’t have the barrel, and reached over and lifted the lid. The alarm when off, water sprayed out, and Howard laughed with glee to see how we had devised such a nice trick. After watching the water spray for about 3 or 4 seconds, he suddenly realized that something was wrong. He dropped the lid and looked down, only to find that it looked like he had just pee’ed his pants.
That was it! That was icing on the cake. Howard laughed even more when he realized what had happened.
The next morning when we came in the shop, we went to look at the experiment, it had been disassembled, or shutdown in some manner. I think some caution tag had been placed there by Gary Wright, the Shift Supervisor stating something like this was a safety hazard, or some such thing.
Anyway, when I went up to the Control Room to ask him why he shutdown our experiment he was adamant that it constituted Horseplay and someone could get hurt. Maybe when the water sprayed on them, they might jerk back and fall down and get hurt. Ok….
I suppose. Though, by the time he took it down, everyone at the plant already knew about it, and we were just in the Phase 2 part of the experiment. In this phase anyone who was looking at the experiment was doing it by opening up the door from the side, and peeing their pants and they wouldn’t jerk back……—- Oh….. I see…. Shift Supervisors don’t usually like to walk into the control room looking like they have just pee’ed their pants.
I will say that I hadn’t expected that type of reaction from Gary Wright, because up to that time, he seemed more mild-mannered than the rest of the Shift Supervisors. We just took it that the more upset Gary was with us about it, the more successful the joke had been implemented. The joke had played out by that time, and we were good with it either way.
After it was all said and done. We thought it did help to reduce the overall tension that was permeating the plant due to the “We’ve Got the Power Program”.

There were times when I was working at the Coal-Fired Power Plant in North Central Oklahoma when I wondered if there was anything that we couldn’t do. Surrounded by True Power Plant Men I found that when we were facing a seemingly impossible task, a Power Plant Man would come up with an extremely creative solution to the problem. One such example was during the “We’ve Got The Power” program. I talked about this program in an early post called “Power Plant We’ve Got the Power Program” so I won’t go into detail here about the program itself. I will just say that we broke out into teams to find creative ways to operate more efficiently, and to cut costs.
I was a team leader of our team, and looking back I must have had two criteria in mind when I picked the team members that would be on my team. The first would have been that they were True Power Plant Men (and woman) with a higher than average intelligence. The second criteria would have been that they were friends of mine. I say this, because everyone on my team fit the bill.
During out team meetings, Terry Blevins would often say some bombastic statement that the average person may be inclined to dismiss immediately as being absurd. I say that because I remember more than once thinking that what Terry had just said wouldn’t amount to much. As it turned out, our biggest money saving ideas were those truly bombastic statements that Terry was making. One such idea had to do with the heaters on the precipitators that kept the hoppers and the insulators on the roof too hot to collect moisture.
The Precipitator is a very large box that takes the ash out of the exhaust before it goes out of the smoke stack (how many times have I made that statement in the last two years?). Anyway, the exhaust from the boiler after the coal has been turned to ash in the fireball in the boiler contains a large amount of moisture. The last thing you want to happen is for the temperature of the flue gas to fall below the dew point. When that happens, moisture collects on the structure in a form of… well… of Acid Rain. Basically eating away the precipitator and the duct work from the inside.
Somewhere along the line, it had been determined that the dewpoint of the flue gas was not higher than 250 degrees. So, as long as the structure was at least 250 degrees, no moisture would be collected. Four heaters were mounted on each of the 84 hoppers (on each of the two precipitators) and heaters were mounted on the roof around each of the insulators that held up the wire racks on both ends.
When Terry walked into the office to attend one of our first “We’ve Got The Power” team meetings, he said, I think we could save a lot of money if we did something about the heaters on the precipitator. — He may remember being greeted with blank stares (at least from me). Um. Ok. Heaters on the precipitator. I knew they were everywhere, but I never gave them much thought.
I think Terry could tell right away that I hadn’t taken his idea seriously. I don’t know. Maybe he was bothered by the sound of my eyeballs rolling around in circles as if someone has conked me on the head. So, he explained his idea further. He pointed out that the roof heaters on just one of the precipitators used about 211 kilowatt-hours and the hopper heaters used about 345 kilowatt-hours. Together it is more than half a Megawatt of power. — This definitely caught our attention. That meant that between both of the Precipitators (since we had two boilers at our plant), we could possibly save over a Megawatt of electricity every hour we could shut down the heaters.
After discussing all the aspects of the idea, we decided that in order for the idea to have any merit, we had to know if the dew point really was around 250 degrees, or was it possibly a lot lower. 250 degrees seemed high to begin with since the boiling point of water is 212 degrees. If lower, then we could have a workable idea. Originally, I wanted to tackle the task of finding the dew point. So, I went about it in a Science Experiment sort of way.
I figured that if we were able to lower the temperature of the flue gas to a known temperature below the dewpoint, and by knowing the volume of the gas, and the amount of liquid we could condense out of it, we could determine (possibly) the dew point. So, I brought my Graham Condenser to work, and Scott Hubbard and I went up to the 250 foot landing on the smoke stack with the intent of sucking a known amount of exhaust from the smoke stack while the unit was at full load.
We would run it through the condenser while running cool water through it to lower the temperature.
I could measure the output of the vacuum pump by filling up an inverted Erlemeyer flask with water and then letting the flue gas displace the water. — I always loved doing experiments like this in the 9th grade science glass with Mr. Godfrey our Physical Science Teacher (Donna Westhoff, who may sometimes read this blog was in my class and sat right behind me).
Ok. Side Story, since I mentioned Donna Westhoff from the 9th grade 1974-75 school year.
I knew that Donna’s father was a fire fighter, because one day during a special outing when we were with a group of bicycling Junior High School students and a teacher, we stopped at Donna Westhoff’s house to get a drink of water. On the walls in her house were different types of fire fighting treasures. Donna explained that her father was a fire fighter… That was the Spring of 1975 in Columbia, Missouri
Fast forward 16 years later (1991) at the Power Plant in the middle of nowhere in North Central Oklahoma. Just about a year after the story I’m telling now…. I left the logic room and went to catch the elevator to the Control room. When the doors opened, Tony Mena was in there with a bunch of college age students giving them a tour of the plant. I entered the elevator and turned around to face the door as it closed.
As I was standing there, I suddenly became aware that the person standing next to me was staring right at me. So, I turned to see who it was. Standing next to me was someone that looked very familiar wearing a big grin as if she knew who I was. I recognized her, and while my mind was going through filing cabinets of memories trying to index this particular person, I asked her, “Don’t I know you?” She shook her head and said, “I’m Donna Westhoff!”
As the elevator door opened and we stepped out, Donna and I began talking about what we were both doing there. She was surprised to find that I had become an electrician at a power plant instead of some kind of scientist in a lab somewhere. Donna was going to school in Stillwater where one of the best Fire Fighting Schools in the country is found. Following in her father’s footsteps, I thought. After a while I could tell that Tony was getting a little perturbed that the wisdom he was imparting about the fire protection system on the Turbine Generator wasn’t being absorbed by Donna, so I cut our conversation short. It turned out that a very good friend of hers lived just two houses from where we lived, and her friend’s mother was my landlord. Peggy Pickens.
Ok. End of the side story, and another example of how I occasionally run into friends from my childhood in the most unexpected places (see the post: “Relay Tests and Radio Quizzes with Ben Davis“).
So. Scott Hubbard and I tried using the Graham Condenser and the Erlenmeyer Flask, but we quickly found out that this wasn’t big enough, to capture a large enough quantity. So, we increased the size of the condenser by winding a garden hose around inside of a water bucket and filling it with ice. Then we captured all the water that condensed in the hose.
When it finally came down to it. Even though it was fun trying to do this experiment halfway up the 500 foot smoke stack, I never was able to figure out how to calculate the dew point given the data I had collected.
That’s when we decided to look at dew point sensors in the parts catalogs. If we could stick a probe down into the precipitator and measure the dew point directly in the flue gas, that would be best. After looking at a few in the catalog, Terry Blevins said he thought he could make one. So, he went to work.
The next day he came in with an inch and a half conduit with hoses hanging out the back and a homemade sensor on the other end. I won’t go into detail how the sensor was built because some day Terry may want to patent this thing because, as it turned out, it was so sensitive that it could detect my breathe from about a foot away. If I breathed out of my mouth toward the sensor, it would detect the moisture in my breath. This was perfect!
We went to work on the roof of the precipitator sticking the probe down into different sections of the precipitator. It not only measured the moisture, it also had thermocouples on it that we used to accurately measure the temperature of the sensor as we varied the temperature by blowing cold air through the conduit using the same ice bucket and hose from before.
I could go into a lot of detail about how we performed our experiments, but it would only excite me and bore you. So, let me just say that we came up with two very important results. First of all, at full load when the humidity outside was at 100% the dew point was around 150 degrees! A full 100 degrees below what the plant had originally assumed. This was very important, because a lot of energy was spent trying to keep the flue gas above 250 degrees, and just by lowering it down to 210 degrees, still a safe amount above the dew point, that extra energy could be used to create electricity.
The second thing that we discovered was that the middle sections of the precipitator was a lot cooler inside than the outer fields. We realized that this was caused by the air preheater coils that rotated between the flue gas and the Primary Air intake duct. This took the last amount of heat possible from the exhaust and transferred it to the air going into the boiler so that it was already hot when it was used to burn the coal. Because of the way the air preheater coils rotated, the part of the duct toward the middle of the precipitator was a lot cooler than the air on the outside.
Lower temperatures in the precipitator increased the performance, so we decided that if we could mix the air around as it was going into the precipitator so that the outer edges were cooler, then it would increase the overall performance. One suggestion was to put a mobile home in the duct work because in Oklahoma it was a known fact that mobile homes attracted tornadoes and it would probably cause a tornadic reaction that would mix up the flue gases. — We just couldn’t figure out how to convince management to put a mobile home in the duct between the economizer and the precipitator.
Thanks to Terry’s handy dandy Dew Point Sensor, we were able to prove that the hopper and roof heaters could be lowered to where we set the thermostat at 180 degrees. At that setting the heaters that used to always run at 250 degrees would remain off anytime the ambient temperature was above 45 degrees. In Oklahoma, that is most of the year. This turned out to save over $350,000 per year in energy savings at a cost of about 1.5 cents per kilowatt-hour. Not to mention the unknown savings from being able to lower the flue gas temperature by 40 degrees.
