Resistance in a Coal-Fired Power Plant

Resistance is Futile! You may have heard that before. Especially if you are a Star Trek Fan. If not, then you know that there is always some form of resistance wherever you are.

I learned a lot about resistance when I first joined the electric shop at the coal-fired power plant in North Central Oklahoma in 1984. I was assigned to work with Sonny Kendrick and Bill Rivers on the Precipitator during overhauls and when I wasn’t working on the manhole pumps and there wasn’t any other emergencies going on. Actually, from 1984 on, on the Precipitator for the next 17 years I continued to work on the precipitator… (if I had only known my fate….).

Not only did I learn a lot about resistance, I also learned about capacitance, reactance, transformers, rectifiers, power supplies, diodes, transistors, op amps, and pots (also known as potentiometers). Bill Rivers was the brains of the outfit. Sonny was the Electric Specialist banished to the Precipitator by Leroy Godfrey (See Singing Along with Sonny Kendrick). Bill thought up the ideas and Sonny went to work to implement them. I just jumped in where I was needed.

The Precipitator is the large box between the boiler and the smokestack (maybe you can see this in the Power plant picture). The purpose of the electrostatic precipitator is to take the smoke (or fly ash) out of the exhaust before it went out of the smokestack.

The plant has a similar electrostatic precipitator, only ours is twice as long

The controls for the Precipitator were all electronic at that time. That meant that there were circuit boards full of resistors, capacitors, transistors, operational amplifiers, diodes and potentiometers. These circuit boards controlled the way the power was distributed throughout the precipitator wires and plates through high powered transformers, and how the rappers and vibrators operated that dropped the collected ash into the hoppers.

Bill had me take an electronics course at the Indian Meridian Vo-tech so I would know the basics. Then he taught me all the shortcuts. I had to be able to look at a resistor and tell right away what the value of resistance it was. Resistors are color-coded and you had to learn what each of the colors represented…

This for instance is a 339 ohm resistor with a 5% tolerance.

This for instance is a 339 ohm resistor with a 5% tolerance.

I was expected to know this by sight. Bill would test me. There was a mnemonic device that I was taught to remember what each color represented, but it is not appropriate to repeat it, so I won’t. It is enough to say that the colors go like this: Black, Brown, Red, Orange, Yellow, Green, Blue, Violet, Gray, White (I will never forget this my entire life). These represent the numbers zero through 9. Here is a full explanation of how to read a resistor….. just in case you are curious, or you are such a boring person that you really need some material to bring up when you are at a party and don’t know what to say:

This is how the color codes work

This is how the color codes work for resistors works

I found that having just the correct amount of resistance was very important. Too much or too less, and everything stops working.

Isn’t it that way with management also? If the management is too resistant to change, then things come to a halt. If they have too little resistance, they lose control of the situation. Depending on the circuit (or managerial decision) and what you are trying to do, it helps to have a manager that has a variable resistance to meet the needs of each situation. Resistance to change is always a balancing act.

During the first two years I was an electrician, the main control panels that controlled the operation of the precipitators were electronic. We spent a lot of time in the lab troubleshooting electric circuits looking for blown (or bad) parts that needed to be replaced. Then we would solder new components on the circuit boards and then put them back in operation. I learned how to be an electronics junky. I became addicted to fixing electronic circuit boards. It was like a game to me.

Later, the precipitator controls were changed to digital controls. That is, they were more like little computers controlling the precipitator. Instead of a bunch of circuit boards dumbly, but cleverly, doing their job, (how many commas can I use in one sentence?), little brains were added that made decisions and reacted to conditions in a much more dynamic way.

What was interesting was that one day Bill Rivers was describing how technology was going to be in the future. He said that some day, we will be able to sit in the lab and look on a computer and see what all the controls in the precipitator were doing (this was 1984). If something isn’t working right, we could just reach over, type a few keys on the computer and adjust the controls. Drink our sweet tea (a necessary staple in Oklahoma at the time), and then wait for the next crisis…. Then he would giggle at the look of disbelief on my face.

When he was telling me this, I was thinking in my head…. Well, that would be nice, but this sounds more like a pipe dream to me than reality. What does an older guy with six kids from a tool and die company in Columbia Missouri (where I grew up, by chance) know about the future of anything….. well…. anything…uh… new age…. If that is what you might call it… I found out you just don’t really know when you are sitting in front of a true “visionary” with tremendous insight.

Bill Rivers had this incredible knack for telling the future. In 1984 he was predicting computer controls in the control room where you ran the entire plant from a computer on a desk instead of using the “Big Board”.

I love this picture!

I love this picture! It makes me feel at home! This was not our plant, but is a Power Plant control room

He said you would be able to call someone on a phone you kept in your pocket or your watch like Dick Tracey.

I don’t know what journals Bill was reading or if he just dreamed all this stuff up in his head, or maybe he was a Star Trek Fan that believed that if you can dream it up you can do it. I do know that he picked up on subtle queues and made great inferences from them that seemed astronomically unlikely. However, I have to admit that he caught me off guard a number of times with predictions that definitely came true.

I will talk about this more in a future post, but for now I will say that we did upgrade the precipitator to where you could sit in the control room and monitor and adjust the precipitator controls (all 84 on each unit), and even each of the rappers (672 rappers) and vibrators (168 vibrators) on the roof of each precipitator. With one key on the computer I could send a plume of ash out of the smokestack that looked like the unit had just tripped, and a moment later, clean it up again. This meant that I could send smoke signals to the Osage Indian tribe 20 miles north up the Arkansas (pronounced “Are Kansas”) river, telling them that the Pow Wow would begin at sunset.

Today, I understand that the “Big Board” at the plant is just a large junction box and the plant is controlled almost (if not) completely by computers sitting on the desk. Before I left the plant in 2001, this was being transitioned slowly to computer controls. I have another story to tell some day about this, and how an operator named Jim Cave, a Power Plant Genius and true Power Plant Man of the highest integrity, was snubbed by upper management for speeding this technology along. — Another example of Power Plant Resistance….

But for now…. back to my electronic days… before I began re-programming the Eeprom chips in the precipitator controls….

An Eeprom Chip used in the preicpiitator controls

An Eeprom Chip used in the precipitator controls which I had a very “personal” relationship with…

Bill Rivers confided with me one day that when the new Instrument and Controls department had been formed from the “Results” department that his dream had been to become a part of this team. It meant the world to him. It was where he believed he belonged. It was one of his major goals in life.

There used to be two electrical specialists in the Power Plant. Sonny Kendrick was not always the only one. The other specialist was chosen to go to the Instrument and Controls shop. Bill Rivers wanted to move there also. He definitely had the experience and the knowledge to be a superb instrument and controls person. But Bill had this one problem.

He loved to joke around. He loved to pull strings and push buttons. I have mentioned in a previous posts that Bill would play a new joke on Sonny Kendrick every single day. As I have unfortunately found out in my own life… this tends to make them…. well….. it tends to make enemies out of those who have a chip on their shoulder. Those people who naturally feel inadequate in their abilities or their position in life. To go one step further…. anyone who feels “unloved”….. these people definitely do not like being joked with. They seem to never forgive you. My greatest regret in life is joking around with these individuals.

So, when it came time to choose who would be a part of the new Instrument and Controls shop, Bill Rivers was turned down. It was explained to him that the reason he was not given the job was because he cut off the leads of a transistor when he replaced them. — I’m not kidding. Bill Rivers had the habit of cutting off the leads of each resistor, transistor, diode or capacitor that he replaced…. this is why Monty Adams turned down his request for joining the “elite” Instrument and Controls shop (as he told Bill to his face).

Someone had told the Instrument and Controls Supervisor Monty Adams that Bill Rivers cut the leads off of transistors and resistors when he replaced them so that you couldn’t test them to see if they were all right. Implying that he didn’t want you to know whether he had replaced the transistor or resistor by mistake.

Bill Rivers took several transistors, cut the leads off of each of them and handed them to me and asked me to test them to see if they were still good or if they were bad. I took out my voltmeter, set it to ohms, and proceeded to test them as Bill Rivers had taught me. I told him…. this transistor is good….. this one is bad….

You see…. there is no way to cut the leads off of a transistor in such a way to make it impossible to tell if a transistor is good or bad…. In reality…. you cut the leads off of a bad transistor so that the person working on the circuit board knows that this is a bad transistor and doesn’t use it again by accident. This was electronics 101.

When Bill told me this story, he literally had tears in his eyes. This was because being part of the Instrument and Controls team was part of his dream. His family and the entire rest of his life was decided the day he was told that he was not going to be a part of a team that he believed was his true lot in life.

I remember his exact words as he sat there in the lab alone and told me this story. He said, “… and Monty didn’t know… He didn’t know that you cut the leads…. that is standard procedure….” In Bill’s giggly way, he was crying out loud as he told me this.

From that point on….I knew that the decisions Bill made in his life were driven by that one decision to exclude him from this team. Unlike many of us that could say to ourselves…. “That is their loss”…. Bill kept this pain in his heart each day…. Every decision from that day further was effected by this event.

I calculated it out one day that I spent 414 hours driving back and forth from Stillwater, Oklahoma to the plant and back each day with Bill Rivers (along with Yvonne Taylor and Rich Litzer and occasionally others that needed a ride), and over that time, I became very close to Bill, even to the point of tutoring his son in Algebra (see post: How Many Power Plant Men Can You Put in a 1982 Honda Civic?).

I say this because I know about the pain that inflicted Bill River by a rash decision based on the hearsay of someone that held a grudge. I know how his entire life was changed and how it ended for Bill Rivers as a power plant employee. I know that every decision by Bill after this date was made in response to this one decision. Anyone who experienced Bill after 1983 knows what I am talking about.

I realized that today my own decisions in life help spell out my future. How some little remark may be misinterpreted, or even properly so. I realize as I write this post that how I accept or reject these events in my life, determines the future of my family. After seeing how every event in Bill’s life after that day at the power company was determined by his experience was to his detriment, I am determined not to let the same thing happened to me…..

That is why I have taken on the philosophy in my life that no matter how my actions are misinterpreted, I am determined to remain true to myself. I know what I mean, and I mean what I say, and I say what I mean, and an Elephant is Faithful 100 %.

    It’s amazing how many decisions are made based on incorrect / incomplete information (at all levels).

Why Do Power Plant Men always Lose the Things they Love the Most?

Originally posted November 9, 2013:

One of the things I loved the most about being an electrician at the coal-fired Power Plant in North Central Oklahoma was that I spent a good deal of time troubleshooting and fixing Electronic Circuit boards. My Mentor Bill Rivers had taught me the fine art of repairing precipitator circuit boards to the point where I was very comfortable taking a board with burned out circuits and rebuilding it piece at a time until it worked well enough to be put back into service. There is something comforting about fixing electronic circuit boards.

I had even built a little test box out of a proximity switch on a Gaitronics phone receiver hook where I could plug a large Operational Amplifier into it and turn a little knob to test it, where it would light up little red LEDs. Like I said. It was really fun.

I had told my friend from High School, Jesse Cheng, who was now a doctor just graduating from Harvard with his Masters in Public Health how much fun I was having. Even though he was a medical doctor with an Engineering degree from Yale, he wished that he could do what I was doing. He even applied for an Engineering job at our plant so that he could at least come down to the electric shop where I would let him help me troubleshoot and repair all kinds of electronic circuit boards.

Unfortunately, he was overqualified for the job. Louise Gates asked me about him, since he had listed me as a reference on the job application. I explained to her that even though he was a Medical Doctor, what he really wanted to do was work in a power plant with the great bunch of people I had told him about. He would easily have given up his career to be blessed by the presence of such great Power Plant Men.

I will tell a side story about my Friend Jesse, before I proceed with the painful loss of those things that Power Plant Men love….

I met Jesse when I was a sophomore in High School. He was the student body president when I arrived at Rockbridge High School in Columbia, Missouri. We immediately became friends when we met. We both enjoyed the same things. The main thing was playing games, or solving puzzles.

I quickly learned that Jesse loved playing all kinds of games. So, when I would go over to his house, we would usually go down in the basement where he had a new game waiting for me. We would sit down there and play games until his mother would call us for dinner.

One day my brother came with me and we went down in the basement to play the game of Risk.

Risk Board Game

Risk Board Game

Jesse was beating us so bad that after the 3rd move, we joined forces only to have Jesse wipe us off of the map on the 4th turn. Then his mother called us for dinner.

Jesse’s mother was a small Chinese lady with a meek voice. When Jesse had guests over, she would cook his favorite meal. Chili. So, when it was time for dinner, she would call down to us from the top of the basement stairs, “Jesse! Come get your Chili!” I had heard that call to action many times, and I had obediently left whatever we were playing to go eat supper.

After we had finished dinner and talked with Jesse for a while, my brother and I left to go home. On the way home my brother started to chuckle. I asked him why, and he responded that he could still hear Jesse’s mother calling “Jesse! Come get your Chili!” in his head. It sounded funny to hear the small Asian voice calling to Jesse to come get his Chili.

So, that became a catch phrase for when you wanted to holler at someone, but didn’t have anything particular to say. We would just yell out, “Jesse! Come get your Chili!!” It always brought a smile to the faces of anyone who knew the story, and a confused look on the faces of any bystanders.

When I went to Columbia, Missouri to the University of Missouri, I told this story to the people that lived around me in Mark Twain Dormitory. I would smile when I would be heading back to the dorm after class and someone from a block away would spy me from their dorm window and would yell at the top of their lungs, “Jesse! Come get your Chili!!!”

Jesse was in town one day shortly after the Christmas break and came to visit me in the dorm. He walked off the elevator looking for the room where I lived. The Resident Assistant saw him and immediately asked him, “Are you Jesse Cheng?” When he replied that he was, he said, “Kevin is in Room 303.” When I answered the door, Jesse said he couldn’t figure out how everyone on the floor seemed to know who he was. I told him that “Everyone knows you Jesse! You’re my friend!”

So, there were times when I was at the plant where a Power Plant Man (or Woman) would yell to me, “Jesse! Come get your Chili!” No one can say that without a big smile on their face, and on mine. It’s poetry to my ears. Jesse’s mother forever lives on in our memories.

End of Side Story….

So, why am I talking about troubleshooting electronic circuit boards in a post about Power Plant Men losing the things they love most? Well… because all good things had to come to an end. Electronic circuit boards included.

When I went to search for a picture of an electronic circuit board on Google Images, I had to page down a couple of times before I found a partial picture of a circuit board that had capacitors, resistors and diodes on it. They just aren’t used much anymore. Everything has gone digital. Instead of troubleshooting electronic parts, you diagnose signals being sent between various processors and memory chips. It just isn’t quite the same.

So, lucky for Jesse that he wasn’t hired at our plant. By the time he would have showed up, we were no longer changing out transistors. We were programming chips. Now the circuit boards looked more like this:

A digital Circuit Board

Other things in the electric shop were taken away or became “unused” that I used to really enjoy using. We had a heat gun mounted on the wall where we would heat up bearings in order to put them on the shaft of the motor. We would stand there monitoring the bearing to see if it was hot enough… We would spit on our finger and drip the spit on the bearing. When the spit would sizzle, we knew the bearing was hot enough.

There was something comforting about the smell of hot grease from the bearing mixed with the smell of smoldering spit… Also in the winter, it felt good to warm yourself around the heat gun while you waited for the bearing to heat up.

Well. Eventually, we no longer used the heat gun. We had a fancier bearing heater that looked like a strange aluminum cone hat.

The bearing heater heated the bearing more uniformly, and we could use a special temperature pencil that would melt when the bearing reached the right temperature. No more boiling bearing grease smell, and no smoldering spit. Oh well….

When the bearing was the right temperature, we had a pair of large white Asbestos Gloves that we would wear to pick up the bearing and slap it onto the shaft of the motor. The pair of Asbestos gloves in our shop came from the old Osage Plant. They were made from genuine Asbestos. I suppose a white cloud of Asbestos dust would fly up in your face if you were overly moved by the song on the radio in the shop and felt a sudden urge to clap.

Well… You can imagine what happened to our Asbestos gloves. Those gloves that you knew were going to keep your hands from being burned as you picked up the scalding hot bearing. You never had to worry about being burned…. but…. oh well… They were taken away. Not deemed safe for use by humans.

In the shop when before and after we took apart a motor, we performed a test on the motor called, “Meggering the motor”. That is, we clipped a megger to the motor leads and one to the motor case and cranked a hand crank on the side of the Megger to generate 1,000 volts to see if the insulation in the motor was still good.

Meggers are much like an old telephone from way back, where you would turn a crank to call the operator. Or you could take it fishing with you and shock the fish in the water to make them float to the surface. But…. I wouldn’t know about that. I just heard stories from other Power Plant Men about it.

Alas…. After a while, a Meggar with a crank became a thing of the past, as did our Simpson Volt-Ohm Meter:

It wasn’t only electric shop equipment that the Power Plant Men held dear that kept disappearing. We used to wear safety belts at the plant to keep us from falling off of high places. Would you believe that these Safety Belts were taken away from the Power Plant Men as well?

I explained how the electronic circuit boards were replaced with digital cards. I also explained how the heat gun was replaced with a nifty new bearing heater, which was also almost made obsolete by another invention called an Induction heater.

This heater didn’t even get hot. The bearing would heat up by a magnetic field on the bar that would cause an electric current to build up around the bearing, causing it to heat up almost by magic.

The Asbestos Gloves were replaced with well padded Kevlar Gloves:

High Heat Kevlar Gloves

They worked just as well as the asbestos gloves without the Mesothelioma thrown in as a bonus.

As for the volt-ohm meters. Each electrician was eventually issued their own new Fluke Volt-Ohm Meter. I dare say. It was a step up from the old Simpson meter. A lot safer also:

Like this. Ok. So the multimeters had become more sophisticated over the years.

Like this. Ok. So the multimeters had become more sophisticated over the years.

And the Safety belt? Well… It turns out that if someone were to fall and be hanging from a safety belt, the injury caused by just dangling for any length of time on a safety belt while waiting to be rescued can be devastating to the human body. So, the belts were removed, and Power Plant Men everywhere were issued new and improved Safety Harnesses.

So… you see… What it boils down to is this…. Power Plant Men generally love their jobs. Real Power Plant Men I mean. So, whenever there is change, they feel the pain of loss. They lose those things they hold dear. Yeah. They know that whatever is replacing the things they are losing will most likely be a new and improved version of what they already had. I think it’s the nostalgia of how things used to be that they miss the most.

So. That is why Power Plant Men always seem to lose the things they love the most. Because they love doing what they do, and things are always changing. Power plant Men just change right along with it. But sometimes it hurts a little

    Great story, Kevin.
    When I transferred to the Seminole Plant, one of my jobs was to do the “daily sheets”. For each generating unit I calculated total MW, steam flow, gas burned, average temperatures and pressures, etc. We were privileged to have the first non-mechanical calculators in an OG&E Power Plant. The old calculators (I used at Mustang and Horseshoe Lake) were mechanical – motors, gears, shafts, levers, dials, and more gears. They made cool sounds when you hit the “Total” key. They even had a unique smell too. We paid $900 for each Monroe calculator in 1970. They didn’t make any noises. They didn’t give off any scent, either. But they were much faster, smaller, and lighter. I missed the old mechanicals. I still have the Post slide rule I used at OU too.

    Sadly, change is progress. I used a blackboard, now it’s a white board!

    I loved your post, change comes in our lives but hopefully in our lives we blossom and become better for it, and always cherish the memories. I smiled a thousand times while reading it and will always remember “Jessie come eat your chili! Blessings!

    Change, yes…but it’s more than that. Old time craftsmen involved a lot of themselves in their work. I remember men who grabbed a wire to determine the voltage on it. A lot of work was done by feel, a sort of extra sense that craftsmen developed on the job. Projects came out right because they knew what was intended and how to make it happen that way. They were an important link in the chain of production.

    Now so much work is untouched by human hands; merely moved along by button-pushers who have replaced true craftsmen. An old time carpenter or electrician could do things today’s replacements never dream of. Cabinet makers and machinists are gone, replaced by machine operators. Much is no doubt gained, but so much is lost…

    An average man in those days, was pretty competent with his hands, expected to have a list of skills and competencies…and that’s gone, too.

In the shop when before and after we took apart a motor, we performed a test on the motor called, “Meggering the motor”. That is, we clipped a megger to the motor leads and one to the motor case and cranked a hand crank on the side of the Megger to generate 1,000 volts to see if the insulation in the motor was still good.

Meggers are much like an old telephone from way back, where you would turn a crank to call the operator. Or you could take it fishing with you and shock the fish in the water to make them float to the surface. But…. I wouldn’t know about that. I just heard stories from other Power Plant Men about it.

It wasn’t only electric shop equipment that the Power Plant Men held dear that kept disappearing. We used to wear safety belts at the plant to keep us from falling off of high places. Would you believe that these Safety Belts were taken away from the Power Plant Men as well?

I explained how the electronic circuit boards were replaced with digital cards. I also explained how the heat gun was replaced with a nifty new bearing heater, which was also almost made obsolete by another invention called an Induction heater.

This heater didn’t even get hot. The bearing would heat up by a magnetic field on the bar that would cause an electric current to build up around the bearing, causing it to heat up almost by magic.

The Asbestos Gloves were replaced with well padded Kevlar Gloves:

They worked just as well as the asbestos gloves without the Mesothelioma thrown in as a bonus.

As for the volt-ohm meters. Each electrician was eventually issued their own new Fluke Volt-Ohm Meter. I dare say. It was a step up from the old Simpson meter. A lot safer also:

Like this. Ok. So the multimeters had become more sophisticated over the years.

And the Safety belt? Well… It turns out that if someone were to fall and be hanging from a safety belt, the injury caused by just dangling for any length of time on a safety belt while waiting to be rescued can be devastating to the human body. So, the belts were removed, and Power Plant Men everywhere were issued new and improved Safety Harnesses.

So… you see… What it boils down to is this…. Power Plant Men generally love their jobs. Real Power Plant Men I mean. So, whenever there is change, they feel the pain of loss. They lose those things they hold dear. Yeah. They know that whatever is replacing the things they are losing will most likely be a new and improved version of what they already had. I think it’s the nostalgia of how things used to be that they miss the most.

So. That is why Power Plant Men always seem to lose the things they love the most. Because they love doing what they do, and things are always changing. Power plant Men just change right along with it. But sometimes it hurts a littl

    Great story, Kevin.
    When I transferred to the Seminole Plant, one of my jobs was to do the “daily sheets”. For each generating unit I calculated total MW, steam flow, gas burned, average temperatures and pressures, etc. We were privileged to have the first non-mechanical calculators in an OG&E Power Plant. The old calculators (I used at Mustang and Horseshoe Lake) were mechanical – motors, gears, shafts, levers, dials, and more gears. They made cool sounds when you hit the “Total” key. They even had a unique smell too. We paid $900 for each Monroe calculator in 1970. They didn’t make any noises. They didn’t give off any scent, either. But they were much faster, smaller, and lighter. I missed the old mechanicals. I still have the Post slide rule I used at OU too.

    Change, yes…but it’s more than that. Old time craftsmen involved a lot of themselves in their work. I remember men who grabbed a wire to determine the voltage on it. A lot of work was done by feel, a sort of extra sense that craftsmen developed on the job. Projects came out right because they knew what was intended and how to make it happen that way. They were an important link in the chain of production.

    Now so much work is untouched by human hands; merely moved along by button-pushers who have replaced true craftsmen. An old time carpenter or electrician could do things today’s replacements never dream of. Cabinet makers and machinists are gone, replaced by machine operators. Much is no doubt gained, but so much is lost…

    An average man in those days, was pretty competent with his hands, expected to have a list of skills and competencies…and that’s gone, too.

 

Resistance in a Coal-Fired Power Plant

Captain Picard as Locutus trying to convince you that "Resistance is Futile"

Captain Picard as Locutus trying to convince you that “Resistance is Futile” Like that is ever going to happen

I learned a lot about resistance when I first joined the electric shop at the coal-fired power plant in North Central Oklahoma in 1984. I was assigned to work with Sonny Kendrick and Bill Rivers on the Precipitator during overhauls and when I wasn’t working on the manhole pumps and there wasn’t any other emergencies going on. Actually, from 1984 on, on, the Precipitator for the next 17 years I continued to work on the precipitator… (if I had only known my fate….).

Not only did I learn a lot about resistance, I also learned about capacitance, reactance, transformers, rectifiers, power supplies, diodes, transistors, op amps, and pots (also known as potentiometers). Bill Rivers was the brains of the outfit. Sonny was the Electric Specialist banished to the Precipitator by Leroy Godfrey (See Singing Along with Sonny Kendrick). Bill thought up the ideas and Sonny went to work to implement them. I just jumped in where I was needed.

The Precipitator is the large box between the boiler and the smokestack (maybe you can see this in the Power plant picture). The purpose of the electrostatic precipitator is to take the smoke (or fly ash) out of the exhaust before it went out of the smokestack. The controls for the Precipitator were all electronic at that time. That meant that there were circuit boards full of resistors, capacitors, transistors, operational amplifiers, diodes and potentiometers. These circuit boards controlled the way the power was distributed throughout the precipitator wires and plates through high powered transformers, and how the rappers and vibrators operated that dropped the collected ash into the hoppers.

Bill had me take an electronics course at the Indian Meridian Vo-tech so I would know the basics. Then he taught me all the shortcuts. I had to be able to look at a resistor and tell right away what the value of resistance it was. Resistors are color-coded and you had to learn what each of the colors represented…

This for instance is a 339 ohm resistor with a 5% tolerance.

This for instance is a 339 ohm resistor with a 5% tolerance.

I was expected to know this by sight. Bill would test me. There was a mnemonic device that I was taught to remember what each color represented, but it is not appropriate to repeat it, so I won’t. It is enough to say that the colors go like this: Black, Brown, Red, Orange, Yellow, Green, Blue, Violet, Gray, White (I will never forget this my entire life). These represent the numbers zero through 9. Here is a full explanation of how to read a resistor….. just in case you are curious, or you are such a boring person that you really need some material to bring up when you are at a party and don’t know what to say:

This is how the color codes work

This is how the color codes work for resistors works

I found that having just the correct amount of resistance was very important. Too much or too less, and everything stops working.

Isn’t it that way with management also? If the management is too resistant to change, then things come to a halt. If they have too little resistance, they lose control of the situation. Depending on the circuit (or managerial decision) and what you are trying to do, it helps to have a manager that has a variable resistance to meet the needs of each situation. Resistance to change is always a balancing act.

During the first two years I was an electrician, the main control panels that controlled the operation of the precipitators were electronic. We spent a lot of time in the lab troubleshooting electric circuits looking for blown (or bad) parts that needed to be replaced. Then we would solder new components on the circuit boards and then put them back in operation. I learned how to be an electronics junky. I became addicted to fixing electronic circuit boards. It was like a game to me.

Later, the precipitator controls were changed to digital controls. That is, they were more like little computers controlling the precipitator. Instead of a bunch of circuit boards dumbly, but cleverly, doing their job, (how many commas can I use in one sentence?), little brains were added that made decisions and reacted to conditions in a much more dynamic way.

What was interesting was that one day Bill Rivers was describing how technology was going to be in the future. He said that some day, we will be able to sit in the lab and look on a computer and see what all the controls in the precipitator were doing (this was 1984). If something isn’t working right, we could just reach over, type a few keys on the computer and adjust the controls. Drink our sweetened tea (a necessary staple in Oklahoma at the time), and then wait for the next crisis…. Then he would giggle at the look of disbelief on my face.

When he was telling me this, I was thinking in my head…. Well, that would be nice, but this sounds more like a pipe dream to me than reality. What does an older guy with six kids from a tool and die company in Columbia Missouri (where I grew up, by chance) know about the future of anything….. well…. anything…uh… new age…. If that is what you might call it… I found out you just don’t really know when you are sitting in front of a true “visionary” with tremendous insight.

Bill Rivers had this incredible knack for telling the future. In 1984 he was predicting computer controls in the control room where you ran the entire plant from a computer on a desk instead of using the “Big Board”.

I love this picture!

I love this picture! It makes me feel at home! This was not our plant, but is a Power Plant control room

He said you would be able to call someone on a phone you kept in your pocket or your watch like Dick Tracey.

I don’t know what journals Bill was reading or if he just dreamed all this stuff up in his head, or maybe he was a Star Trek Fan that believed that if you can dream it up you can do it. I do know that he picked up on subtle queues and made great inferences from them that seemed astronomically unlikely. However, I have to admit that he caught me off guard a number of times with predictions that definitely came true.

I will talk about this more in a future post, but for now I will say that we did upgrade the precipitator to where you could sit in the control room and monitor and adjust the precipitator controls (all 84 on each unit), and even each of the rappers (672 rappers) and vibrators (168 vibrators) on the roof of each precipitator. With one key on the computer I could send a plume of ash out of the smokestack that looked like the unit had just tripped, and a moment later, clean it up again. This meant that I could send smoke signals to the Osage Indian tribe 20 miles north up the Arkansas (pronounced “Are Kansas”) river, telling them that the Pow Wow would begin at sunset.

Today, I understand that the “Big Board” at the plant is just a large junction box and the plant is controlled almost (if not) completely by computers sitting on the desk. Before I left the plant in 2001, this was being transitioned slowly to computer controls. I have another story to tell some day about this, and how an operator named Jim Cave, a Power Plant Genius and true Power Plant Man of the highest integrity, was snubbed by upper management for speeding this technology along. — Another example of Power Plant Resistance….

But for now…. back to my electronic days… before I began re-programming the Eeprom chips in the precipitator controls….

An Eeprom Chip used in the preicpiitator controls

An Eeprom Chip used in the precipitator controls which I had a very “personal” relationship with…

Bill Rivers confided with me one day that when the new Instrument and Controls department had been formed from the “Results” department that his dream had been to become a part of this team. It meant the world to him. It was where he believed he belonged. It was one of his major goals in life.

There used to be two electrical specialists in the Power Plant. Sonny Kendrick was not always the only one. The other specialist was chosen to go to the Instrument and Controls shop. Bill Rivers wanted to move there also. He definitely had the experience and the knowledge to be a superb instrument and controls person. But Bill had this one problem.

He loved to joke around. He loved to pull strings and push buttons. I have mentioned in a previous posts that Bill would play a new joke on Sonny Kendrick every single day. As I have unfortunately found out in my own life… this tends to make them…. well….. it tends to make enemies out of those who have a chip on their shoulder. Those people who naturally feel inadequate in their abilities or their position in life. To go one step further…. anyone who feels “unloved”….. these people definitely do not like being joked with. They seem to never forgive you. My greatest regret in life is joking around with these individuals.

So, when it came time to choose who would be a part of the new Instrument and Controls shop, Bill Rivers was turned down. It was explained to him that the reason he was not given the job was because he cut off the leads of a resistor when he replaced them. — I’m not kidding. Bill Rivers had the habit of cutting off the leads of each resistor, transistor, diode or capacitor that he replaced…. this is why Monty Adams turned down his request for joining the “elite” Instrument and Controls shop (as he told Bill to his face).

Someone had told the Instrument and Controls Supervisor Monty Adams that Bill Rivers cut the leads off of transistors and resistors when he replaced them so that you couldn’t test them to see if they were all right. Implying that he didn’t want you to know whether he had replaced the transistor or resistor by mistake.

Bill Rivers took several transistors, cut the leads off of each of them and handed them to me and asked me to test them to see if they was still good or if they were bad. I took out my voltmeter, set it to ohms, and proceeded to test them as Bill Rivers had taught me. I told him…. this transistor is good….. this one is bad….

You see…. there is no way to cut the leads off of a transistor in such a way to make it impossible to tell if a transistor is good or bad…. In reality…. you cut the leads off of a bad transistor so that the person working on the circuit board knows that this is a bad transistor and doesn’t use it again by accident. This was electronics 101.

When Bill told me this story, he literally had tears in his eyes. This was because being part of the Instrument and Controls team was part of his dream. His family and the entire rest of his life was decided the day he was told that he was not going to be a part of a team that he believed was his true lot in life.

I remember his exact words as he sat there in the lab alone and told me this story. He said, “… and Monty didn’t know… He didn’t know that you cut the leads…. that is standard procedure….” In Bill’s giggly way, he was crying out loud as he told me this.

From that point on….I knew that the decisions Bill made in his life were driven by that one decision to exclude him from this team. Unlike many of us that could say to ourselves…. “That is their loss”…. Bill kept this pain in his heart each day…. Every decision from that day further was effected by this event.

I calculated it out one day that I spent 414 hours driving back and forth from Stillwater, Oklahoma to the plant and back each day with Bill Rivers (along with Yvonne Taylor and Rich Litzer and occasionally others that needed a ride), and over that time, I became very close to Bill, even to the point of tutoring his son in Algebra (see post: How Many Power Plant Men Can You Put in a 1982 Honda Civic?).

I say this because I know about the pain that inflicted Bill River by a rash decision based on the hearsay of someone that held a grudge. I know how his entire life was changed and how it ended for Bill Rivers as a power plant employee. I know that every decision by Bill after this date was made in response to this one decision. Anyone who experienced Bill after 1983 knows what I am talking about.

I realized that today my own decisions in life help spell out my future. How some little remark may be misinterpreted, or even properly so. I realize as I write this post that how I accept or reject these events in my life, determines the future of my family. After seeing how every event in Bill’s life after that day at the power company was determined by his experience was to his detriment, I am determined not to let the same thing happened to me…..

That is why I have taken on the philosophy in my life that no matter how my actions are misinterpreted, I am determined to remain true to myself. I know what I mean, and I mean what I say, and I say what I mean, and an Elephant is Faithful 100 %.

Why Do Power Plant Men always Lose the Things they Love the Most? — Repost

Originally posted November 9, 2013:

One of the things I loved the most about being an electrician at the coal-fired Power Plant in North Central Oklahoma was that I spent a good deal of time troubleshooting and fixing Electronic Circuit boards.  My Mentor Bill Rivers had taught me the fine art of repairing precipitator circuit boards to the point where I was very comfortable taking a board with burned out circuits and rebuilding it piece at a time until it worked well enough to be put back into service.  There is something comforting about fixing electronic circuit boards.

I had even built a little test box out of a proximity switch on a Gaitronics phone receiver hook where I could plug a large Operational Amplifier into it and turn a little knob to test it, where it would light up little red LEDs.  Like I said.  It was really fun.

I had told my friend from High School, Jesse Cheng, who was now a doctor just graduating from Harvard with his Masters in Public Health how much fun I was having.  Even though he was a medical doctor with an Engineering degree from Yale, he wished that he could do what I was doing.  He even applied for an Engineering job at our plant so that he could at least come down to the electric shop where I would let him help me troubleshoot and repair all kinds of electronic circuit boards.

Unfortunately, he was overqualified for the job.  Louise Gates asked me about him, since he had listed me as a reference on the job application.  I explained to her that even though he was a Medical Doctor, what he really wanted to do was work in a power plant with the great bunch of people I had told him about.  He would easily have given up his career to be blessed by the presence of such great Power Plant Men.

I will tell a side story about my Friend Jesse, before I proceed with the painful loss of those things that Power Plant Men love….

I met Jesse when I was a sophomore in High School.  He was the student body president when I arrived at Rockbridge High School in Columbia, Missouri.  We immediately became friends when we met.  We both enjoyed the same things.  The main thing was playing games, or solving puzzles.

I quickly learned that Jesse loved playing all kinds of games.  So, when I would go over to his house, we would usually go down in the basement where he had a new game waiting for me.  We would sit down there and play games until his mother would call us for dinner.

One day my brother came with me and we went down in the basement to play the game of Risk.

Risk Board Game

Risk Board Game

Jesse was beating us so bad that after the 3rd move, we joined forces only to have Jesse wipe us off of the map on the 4th turn.  Then his mother called us for dinner.

Jesse’s mother was a small Chinese lady with a meek voice.  When Jesse had guests over, she would cook his favorite meal.  Chili.  So, when it was time for dinner, she would call down to us from the top of the basement stairs, “Jesse!  Come get your Chili!”  I had heard that call to action many times, and I had obediently left whatever we were playing to go eat supper.

After we had finished dinner and talked with Jesse for a while, my brother and I left to go home.  On the way home my brother started to chuckle.  I asked him why, and he responded that he could still hear Jesse’s mother calling “Jesse!  Come get your Chili!” in his head.  It sounded funny to hear the small Asian voice calling to Jesse to come get his Chili.

So, that became a catch phrase for when you wanted to holler at someone, but didn’t have anything particular to say.  We would just yell out, “Jesse!  Come get your Chili!!”  It always brought a smile to the faces of anyone who knew the story, and a confused look on the faces of any bystanders.

When I went to Columbia, Missouri to the University of Missouri, I told this story to the people that lived around me in Mark Twain Dormitory.  I would smile when I would be heading back to the dorm after class and someone from a block away would spy me from their dorm window and would yell at the top of their lungs, “Jesse!  Come get your Chili!!!”

Jesse was in town one day shortly after the Christmas break and came to visit me in the dorm.  He walked off the elevator looking for the room where I lived.  The Resident Assistant saw him and immediately asked him, “Are you Jesse Cheng?”  When he replied that he was, he said, “Kevin is in Room 303.”   When I answered the door, Jesse said he couldn’t figure out how everyone on the floor seemed to know who he was.  I told him that “Everyone knows you Jesse!  You’re my friend!”

So, there were times when I was at the plant where a Power Plant Man (or Woman) would yell to me, “Jesse!  Come get your Chili!”  No one can say that without a big smile on their face, and on mine.  It’s poetry to my ears.  Jesse’s mother forever lives on in our memories.

End of Side Story….

So, why am I talking about troubleshooting electronic circuit boards in a post about Power Plant Men losing the things they love most?  Well… because all good things had to come to an end.  Electronic circuit boards included.

When I went to search for a picture of an electronic circuit board on Google Images, I had to page down a couple of times before I found a partial picture of a circuit board that had capacitors, resistors and diodes on it.  They just aren’t used much anymore.  Everything has gone digital.  Instead of troubleshooting electronic parts, you diagnose signals being sent between various processors and memory chips.  It just isn’t quite the same.

So, lucky for Jesse that he wasn’t hired at our plant.  By the time he would have showed up, we were no longer changing out transistors.  We were programming chips.  Now the circuit boards looked more like this:

A digital Circuit Board

A digital Circuit Board

Other things in the electric shop were taken away or became “unused” that I used to really enjoy using.  We had a heat gun mounted on the wall where we would heat up bearings in order to put them on the shaft of the motor.  We would stand there monitoring the bearing to see if it was hot enough… We would spit on our finger and drip the spit on the bearing.  When the spit would sizzle, we knew the bearing was hot enough.

A heat gun like this

A heat gun like this

There was something comforting about the smell of hot grease from the bearing mixed with the smell of smoldering spit…  Also in the winter, it felt good to warm yourself around the heat gun while you waited for the bearing to heat up.

Well.  Eventually, we no longer used the heat gun.  We had a fancier bearing heater that looked like a strange aluminum cone hat.

A bearing heater

A bearing heater

The bearing heater heated the bearing more uniformly, and we could use a special temperature pencil that would melt when the bearing reached the right temperature.  No more boiling bearing grease smell, and no smoldering spit.  Oh well….

When the bearing was the right temperature, we had a pair of large white Asbestos Gloves that we would wear to pick up the bearing and slap it onto the shaft of the motor.  The pair of Asbestos gloves in our shop came from the old Osage Plant.  They were made from genuine Asbestos.  I suppose a white cloud of Asbestos dust would fly up in your face if you were overly moved by the song on the radio in the shop and felt a sudden urge to clap.

Well… You can imagine what happened to our Asbestos gloves.  Those gloves that you knew were going to keep your hands from being burned as you picked up the scalding hot bearing.  You never had to worry about being burned…. but…. oh well…  They were taken away.  Not deemed safe for use by humans.

I wouldn’t know about that.  I just heard stories from other Power Plant Men about it.

    Change, yes…but it’s more than that. Old time craftsmen involved a lot of themselves in their work. I remember men who grabbed a wire to determine the voltage on it. A lot of work was done by feel, a sort of extra sense that craftsmen developed on the job. Projects came out right because they knew what was intended and how to make it happen that way. They were an important link in the chain of production.

    Now so much work is untouched by human hands; merely moved along by button-pushers who have replaced true craftsmen.

Not only did I learn a lot about resistance, I also learned about capacitance, reactance, transformers, rectifiers, power supplies, diodes, transistors, op amps, and pots (also known as potentiometers).  Bill Rivers was the brains of the outfit.  Sonny was the Electric Specialist banished to the Precipitator by Leroy Godfrey (See Singing Along with Sonny Kendrick).  Bill thought up the ideas and Sonny went to work to implement them.  I just jumped in where I was needed.

The Precipitator is the large box between the boiler and the smokestack (maybe you can see this in the Power plant picture).  The purpose of the electrostatic precipitator is to take the smoke (or fly ash) out of the exhaust before it went out of the smokestack.  The controls for the Precipitator were all electronic at that time.  That meant that there were circuit boards full of resistors, capacitors, transistors, operational amplifiers, diodes and potentiometers.  These circuit boards controlled the way the power was distributed throughout the precipitator wires and plates through high powered transformers, and how the rappers and vibrators operated that dropped the collected ash into the hoppers.

Bill had me take an electronics course at the Indian Meridian Vo-tech so I would know the basics.  Then he taught me all the shortcuts.  I had to be able to look at a resistor and tell right away what the value of resistance it was.  Resistors are color-coded and you had to learn what each of the colors represented…

This for instance is a 339 ohm resistor with a 5% tolerance.

This for instance is a 339 ohm resistor with a 5% tolerance.

I was expected to know this by sight.  Bill would test me.  There was a mnemonic device that I was taught to remember what each color represented, but it is not appropriate to repeat it, so I won’t.  It is enough to say that the colors go like this:  Black, Brown, Red, Orange, Yellow, Green, Blue, Violet, Gray, White (I will never forget this my entire life).  These represent the numbers zero through 9.   Here is a full explanation of how to read a resistor….. just in case you are curious, or you are such a boring person that you really need some material to bring up when you are at a party and don’t know what to say:

This is how the color codes work

This is how the color codes work for resistors works

I found that having just the correct amount of resistance was very important.  Too much or too less, and everything stops working.

Isn’t it that way with management also?  If the management is too resistant to change, then things come to a halt.  If they have too little resistance, they lose control of the situation.  Depending on the circuit (or managerial decision) and what you are trying to do, it helps to have a manager that has a variable resistance to meet the needs of each situation.   Resistance to change is always a balancing act.

During the first two years I was an electrician, the main control panels that controlled the operation of the precipitators were electronic.  We spent a lot of time in the lab troubleshooting electric circuits looking for blown (or bad) parts that needed to be replaced.  Then we would solder new components on the circuit boards and then put them back in operation.  I learned how to be an electronics junky.  I became addicted to fixing electronic circuit boards.  It was like a game to me.

Later, the precipitator controls were changed to digital controls.  That is, they were more like little computers controlling the precipitator. Instead of a bunch of circuit boards dumbly, but cleverly, doing their job, (how many commas can I use in one sentence?), little brains were added that made decisions and reacted to conditions in a much more dynamic way.

What was interesting was that one day Bill Rivers was describing how technology was going to be in the future.  He said that some day, we will be able to sit in the lab and look on a computer and see what all the controls in the precipitator were doing (this was 1984).  If something isn’t working right, we could just reach over, type a few keys on the computer and adjust the controls.  Drink our sweetened tea (a necessary staple in Oklahoma at the time), and then wait for the next crisis…. Then he would giggle at the look of disbelief on my face.

When he was telling me this, I was thinking in my head…. Well, that would be nice, but this sounds more like a pipe dream to me than reality.  What does an older guy with six kids from a tool and die company in Columbia Missouri (where I grew up, by chance) know about the future of anything….. well…. anything…uh… new age….  If that is what you might call it…  I found out you just don’t really know when you are sitting in front of a true “visionary” with tremendous insight.

Bill Rivers had this incredible knack for telling the future.  In 1984 he was predicting computer controls in the control room where you ran the entire plant from a computer on a desk instead of using the “Big Board”.

I love this picture!

I love this picture! It makes me feel at home!  This was not our plant, but is a Power Plant control room

He said you would be able to call someone on a phone you kept in your pocket or your watch like Dick Tracey.

I don’t know what journals Bill was reading or if he just dreamed all this stuff up in his head, or maybe he was a Star Trek Fan that believed that if you can dream it up you can do it.  I do know that he picked up on subtle queues and made great inferences from them that seemed astronomically unlikely.  However, I have to admit that he caught me off guard a number of times with predictions that definitely came true.

I will talk about this more in a future post, but for now I will say that we did upgrade the precipitator to where you could sit in the control room and monitor and adjust the precipitator controls (all 84 on each unit), and even each of the rappers (672 rappers) and vibrators (168 vibrators) on the roof of each precipitator.  With one key on the computer I could send a plume of ash out of the smokestack that looked like the unit had just tripped, and a moment later, clean it up again.  This meant that I could send smoke signals to the Osage Indian tribe 20 miles north up the Arkansas (pronounced “Are Kansas”) river, telling them that the Pow Wow would begin at sunset.

Today, I understand that the “Big Board” at the plant is just a large junction box and the plant is controlled almost (if not) completely by computers sitting on the desk.  Before I left the plant in 2001, this was being transitioned slowly to computer controls.  I have another story to tell some day about this, and how an operator named Jim Cave, a Power Plant Genius and true Power Plant Man of the highest integrity, was snubbed by upper management for speeding this technology along.  — Another example of Power Plant Resistance….

But for now…. back to my electronic days… before I began re-programming the Eeprom chips in the precipitator controls….

An Eeprom Chip used in the preicpiitator controls

An Eeprom Chip used in the precipitator controls which I had a very “personal” relationship with…

Bill Rivers confided with me one day that when the new Instrument and Controls department had been formed from the “Results” department that his dream had been to become a part of this team.  It meant the world to him.  It was where he believed he belonged.  It was one of his major goals in life.

There used to be two electrical specialists in the Power Plant.  Sonny Kendrick was not always the only one.  The other specialist was chosen to go to the Instrument and Controls shop. Bill Rivers wanted to move there also.  He definitely had the experience and the knowledge to be a superb instrument and controls person.  But Bill had this one problem.

He loved to joke around.  He loved to pull strings and push buttons.  I have mentioned in a previous posts that Bill would play a new joke on Sonny Kendrick every single day.  As I have unfortunately found out in my own life… this tends to make them…. well….. it tends to make enemies out of those who have a chip on their shoulder.  Those people who naturally feel inadequate in their abilities or their position in life.  To go one step further…. anyone who feels “unloved”….. these people definitely do not like being joked with.  They seem to never forgive you.  My greatest regret in life is joking around with these individuals.

So, when it came time to choose who would be a part of the new Instrument and Controls shop, Bill Rivers was turned down.  It was explained to him that the reason he was not given the job was because he cut off the leads of a resistor when he replaced them.  — I’m not kidding.  Bill Rivers had the habit of cutting off the leads of each resistor, transistor, diode or capacitor that he replaced…. this is why Monty Adams turned down his request for joining the “elite” Instrument and Controls shop (as he told Bill to his face).

Someone had told the Instrument and Controls Supervisor Monty Adams that Bill Rivers cut the leads off of transistors and resistors when he replaced them so that you couldn’t test them to see if they were all right.  Implying that he didn’t want you to know whether he had replaced the transistor or resistor by mistake.

Bill Rivers took several transistors, cut the leads off of each of them and handed them to me and asked me to test them to see if they was still good or if they were bad.  I took out my voltmeter, set it to ohms, and proceeded to test them as Bill Rivers had taught me.  I told him…. this transistor is good….. this one is bad….

You see…. there is no way to cut the leads off of a transistor in such a way to make it impossible to tell if a transistor is good or bad…. In reality…. you cut the leads off of a bad transistor so that the person working on the circuit board knows that this is a bad transistor and doesn’t use it again by accident.  This was electronics 101.

When Bill told me this story, he literally had tears in his eyes. This was because being part of the Instrument and Controls team was part of his dream.  His family and the entire rest of his life was decided the day he was told that he was not going to be a part of a team that he believed was his true lot in life.

I remember his exact words as he sat there in the lab alone and told me this story.  He said, “… and Monty didn’t know… He didn’t know that you cut the leads….  that is standard procedure….”  In Bill’s giggly way, he was crying out loud as he told me this.

From that point on….I knew that the decisions Bill made in his life were driven by that one decision to exclude him from this team.  Unlike many of us that could say to ourselves…. “That is their loss”…. Bill kept this pain in his heart each day…. Every decision from that day further was effected by this event.

I calculated it out one day that I spent 414 hours driving back and forth from Stillwater, Oklahoma to the plant and back each day with Bill Rivers (along with Yvonne Taylor and Rich Litzer and occasionally others that needed a ride),  and over that time,  I became very close to Bill, even to the point of tutoring his son in Algebra (see post:   How Many Power Plant Men Can You Put in a 1982 Honda Civic?).

I say this because I know about the pain that inflicted Bill River by a rash decision based on the hearsay of someone that held a grudge.   I know how his entire life was changed and how it ended for Bill Rivers as a power plant employee.  I know that every decision by Bill after this date was made in response to this one decision.  Anyone who experienced Bill after 1983 knows what I am talking about.

I realized that today my own decisions in life help spell out my future.  How some little remark may be misinterpreted, or even properly so.  I realize as I write this post that how I accept or reject these events in my life, determines the future of my family.  After seeing how every event in Bill’s life after that day at the power company was determined by his experience was to his detriment, I am determined not to let the same thing happened to me…..

That is why I have taken on the philosophy in my life that no matter how my actions are misinterpreted, I am determined to remain true to myself.  I know what I mean, and I mean what I say, and I say what I mean, and an Elephant is Faithful 100 %.

    It’s amazing how many decisions are made based on incorrect / incomplete information (at all levels).

Why Do Power Plant Men always Lose the Things they Love the Most?

One of the things I loved the most about being an electrician at the coal-fired Power Plant in North Central Oklahoma was that I spent a good deal of time troubleshooting and fixing Electronic Circuit boards.  My Mentor Bill Rivers had taught me the fine art of repairing precipitator circuit boards to the point where I was very comfortable taking a board with burned out circuits and rebuilding it piece at a time until it worked well enough to be put back into service.  There is something comforting about fixing electronic circuit boards.

I had even built a little test box out of a proximity switch on a Gaitronics phone receiver hook where I could plug a large Operational Amplifier into it and turn a little knob to test it, where it would light up little red LEDs.  Like I said.  It was really fun.

I had told my friend from High School, Jesse Cheng, who was now a doctor just graduating from Harvard with his Masters in Public Health how much fun I was having.  Even though he was a medical doctor with an Engineering degree from Yale, he wished that he could do what I was doing.  He even applied for an Engineering job at our plant so that he could at least come down to the electric shop where I would let him help me troubleshoot and repair all kinds of electronic circuit boards.

Unfortunately, he was overqualified for the job.  Louise Gates asked me about him, since he had listed me as a reference on the job application.  I explained to her that even though he was a Medical Doctor, what he really wanted to do was work in a power plant with the great bunch of people I had told him about.  He would easily have given up his career to be blessed by the presence of such great Power Plant Men.

I will tell a side story about my Friend Jesse, before I proceed with the painful loss of those things that Power Plant Men love….

I met Jesse when I was a sophomore in High School.  He was the student body president when I arrived at Rockbridge High School in Columbia, Missouri.  We immediately became friends when we met.  We both enjoyed the same things.  The main thing was playing games, or solving puzzles.

I quickly learned that Jesse loved playing all kinds of games.  So, when I would go over to his house, we would usually go down in the basement where he had a new game waiting for me.  We would sit down there and play games until his mother would call us for dinner.

One day my brother came with me and we went down in the basement to play the game of Risk.

Risk Board Game

Risk Board Game

Jesse was beating us so bad that after the 3rd move, we joined forces only to have Jesse wipe us off of the map on the 4th turn.  Then his mother called us for dinner.

Jesse’s mother was a small Chinese lady with a meek voice.  When Jesse had guests over, she would cook his favorite meal.  Chili.  So, when it was time for dinner, she would call down to us from the top of the basement stairs, “Jesse!  Come get your Chili!”  I had heard that call to action many times, and I had obediently left whatever we were playing to go eat supper.

After we had finished dinner and talked with Jesse for a while, my brother and I left to go home.  On the way home my brother started to chuckle.  I asked him why, and he responded that he could still hear Jesse’s mother calling “Jesse!  Come get your Chili!” in his head.  It sounded funny to hear the small Asian voice calling to Jesse to come get his Chili.

So, that became a catch phrase for when you wanted to holler at someone, but didn’t have anything particular to say.  We would just yell out, “Jesse!  Come get your Chili!!”  It always brought a smile to the faces of anyone who knew the story, and a confused look on the faces of any bystanders.

When I went to Columbia, Missouri to the University of Missouri, I told this story to the people that lived around me in Mark Twain Dormitory.  I would smile when I would be heading back to the dorm after class and someone from a block away would spy me from their dorm window and would yell at the top of their lungs, “Jesse!  Come get your Chili!!!”

Jesse was in town one day shortly after the Christmas break and came to visit me in the dorm.  He walked off the elevator looking for the room where I lived.  The Resident Assistant saw him and immediately asked him, “Are you Jesse Cheng?”  When he replied that he was, he said, “Kevin is in Room 303.”   When I answered the door, Jesse said he couldn’t figure out how everyone on the floor seemed to know who he was.  I told him that “Everyone knows you Jesse!  You’re my friend!”

So, there were times when I was at the plant where a Power Plant Man (or Woman) would yell to me, “Jesse!  Come get your Chili!”  No one can say that without a big smile on their face, and on mine.  It’s poetry to my ears.  Jesse’s mother forever lives on in our memories.

End of Side Story….

So, why am I talking about troubleshooting electronic circuit boards in a post about Power Plant Men losing the things they love most?  Well… because all good things had to come to an end.  Electronic circuit boards included.

When I went to search for a picture of an electronic circuit board on Google Images, I had to page down a couple of times before I found a partial picture of a circuit board that had capacitors, resistors and diodes on it.  They just aren’t used much anymore.  Everything has gone digital.  Instead of troubleshooting electronic parts, you diagnose signals being sent between various processors and memory chips.  It just isn’t quite the same.

So, lucky for Jesse that he wasn’t hired at our plant.  By the time he would have showed up, we were no longer changing out transistors.  We were programming chips.  Now the circuit boards looked more like this:

A digital Circuit Board

Other things in the electric shop were taken away or became “unused” that I used to really enjoy using.  We had a heat gun mounted on the wall where we would heat up bearings in order to put them on the shaft of the motor.  We would stand there monitoring the bearing to see if it was hot enough… We would spit on our finger and drip the spit on the bearing.  When the spit would sizzle, we knew the bearing was hot enough.

A heat gun like this

There was something comforting about the smell of hot grease from the bearing mixed with the smell of smoldering spit…  Also in the winter, it felt good to warm yourself around the heat gun while you waited for the bearing to heat up.

Well.  Eventually, we no longer used the heat gun.  We had a fancier bearing heater that looked like a strange aluminum cone hat.

The bearing heater heated the bearing more uniformly, and we could use a special temperature pencil that would melt when the bearing reached the right temperature.  No more boiling bearing grease smell, and no smoldering spit.  Oh well….

When the bearing was the right temperature, we had a pair of large white Asbestos Gloves that we would wear to pick up the bearing and slap it onto the shaft of the motor.  The pair of Asbestos gloves in our shop came from the old Osage Plant.  They were made from genuine Asbestos.  I suppose a white cloud of Asbestos dust would fly up in your face if you were overly moved by the song on the radio in the shop and felt a sudden urge to clap.

Asbestos Gloves worn when putting hot bearings on a motor shaft (for instance)

Well… You can imagine what happened to our Asbestos gloves.  Those gloves that you knew were going to keep your hands from being burned as you picked up the scalding hot bearing.  You never had to worry about being burned…. but…. oh well…  They were taken away.  Not deemed safe for use by humans.

In the shop when before and after we took apart a motor, we performed a test on the motor called, “Meggering the motor”.  That is, we clipped a megger to the motor leads and one to the motor case and cranked a hand crank on the side of the Megger to generate 1,000 volts to see if the insulation in the motor was still good.

Meggers are much like an old telephone from way back, where you would turn a crank to call the operator.  Or you could take it fishing with you and shock the fish in the water to make them float to the surface.   But…. I wouldn’t know about that.  I just heard stories from other Power Plant Men about it.

Alas…. After a while, a Meggar with a crank became a thing of the past, as did our Simpson Volt-Ohm Meter:

It wasn’t only electric shop equipment that the Power Plant Men held dear that kept disappearing.  We used to wear safety belts at the plant to keep us from falling off of high places.  Would you believe that these Safety Belts were taken away from the Power Plant Men as well?

Power Plant Men wore Safety Belts like this

I explained how the electronic circuit boards were replaced with digital cards.  I also explained how the heat gun was replaced with a nifty new bearing heater, which was also almost made obsolete by another invention called an Induction heater.

This heater didn’t even get hot.  The bearing would heat up by a magnetic field on the bar that would cause an electric current to build up around the bearing, causing it to heat up almost by magic.

The Asbestos Gloves were replaced with well padded Kevlar Gloves:

High Heat Kevlar Gloves

High Heat Kevlar Gloves

They worked just as well as the asbestos gloves without the Mesothelioma thrown in as a bonus.

As for the volt-ohm meters.  Each electrician was eventually issued their own new Fluke Volt-Ohm Meter.  I dare say.  It was a step up from the old Simpson meter.  A lot safer also:

Like this.  Ok.  So the multimeters had become more sophisticated over the years.

Like this. Ok. So the multimeters had become more sophisticated over the years.

And the Safety belt?  Well… It turns out that if someone were to fall and be hanging from a safety belt, the injury caused by just dangling for any length of time on a safety belt while waiting to be rescued can be devastating to the human body.  So, the belts were removed, and Power Plant Men everywhere were issued new and improved Safety Harnesses.

So… you see…  What it boils down to is this…. Power Plant Men generally love their jobs.  Real Power Plant Men I mean.  So, whenever there is change, they feel the pain of loss.  They lose those things they hold dear.  Yeah.  They know that whatever is replacing the things they are losing will most likely be a new and improved version of what they already had.  I think it’s the nostalgia of how things used to be that they miss the most.

So.  That is why Power Plant Men always seem to lose the things they love the most.  Because they love doing what they do, and things are always changing.  Power plant Men just change right along with it.  But sometimes it hurts a little.

Resistance in a Coal-Fired Power Plant

Resistance is Futile!  You may have heard that before.  Especially if you are a Star Trek Fan.  If not, then you know that there is always some form of resistance wherever you are.

I learned a lot about resistance when I first joined the electric shop at the coal-fired power plant in North Central Oklahoma in 1984.  I was assigned to work with Sonny Kendrick and Bill Rivers on the Precipitator during overhauls and when I wasn’t working on the manhole pumps and there wasn’t any other emergencies going on.  Actually, from 1984 on, on, the Precipitator for the next 17 years I continued to work on the precipitator… (if I had only known my fate….).

You see…. there is no way to cut the leads off of a transistor in such a way to make it impossible to tell if a transistor is good or bad…. In reality…. you cut the leads off of a bad transistor so that the person working on the circuit board knows that this is a bad transistor and doesn’t use it again by accident.  This was electronics 101.

When Bill told me this story, he literally had tears in his eyes. This was because being part of the Instrument and Controls team was part of his dream.  His family and the entire rest of his life was decided the day he was told that he was not going to be a part of a team that he believed was his true lot in life.

I remember his exact words as he sat there in the lab alone and told me this story.  He said, “… and Monty didn’t know… He didn’t know that you cut the leads….  that is standard procedure….”  In Bill’s giggly way, he was crying out loud as he told me this.

From that point on….I knew that the decisions Bill made in his life were driven by that one decision to exclude him from this team.  Unlike many of us that could say to ourselves…. “That is their loss”…. Bill kept this pain in his heart each day…. Every decision from that day further was effected by this event.

I calculated it out one day that I spent 414 hours driving back and forth from Stillwater, Oklahoma to the plant and back each day with Bill Rivers (along with Yvonne Taylor and Rich Litzer and occasionally others that needed a ride),  and over that time,  I became very close to Bill, even to the point of tutoring his son in Algebra (see post:   How Many Power Plant Men Can You Put in a 1982 Honda Civic?).

I say this because I know about the pain that inflicted Bill River by a rash decision based on the hearsay of someone that held a grudge.   I know how his entire life was changed and how it ended for Bill Rivers as a power plant employee.  I know that every decision by Bill after this date was made in response to this one decision.  Anyone who experienced Bill after 1983 knows what I am talking about.

I realized that today my own decisions in life help spell out my future.  How some little remark may be misinterpreted, or even properly so.  I realize as I write this post that how I accept or reject these events in my life, determines the future of my family.  After seeing how every event in Bill’s life after that day at the power company was determined by his experience was to his detriment, I am determined not to let the same thing happened to me…..

That is why I have taken on the philosophy in my life that no matter how my actions are misinterpreted, I am determined to remain true to myself.  I know what I mean, and I mean what I say, and I say what I mean, and an Elephant is Faithful 100 %.
