Step-by-step volume pot repair. Put the thought

Willie Sims · From: PADUCAH, KY, USA

Only previous post I told some other fellows that I wwould, post a step-by-step guide on how to repair volume pots. I am assuming that anyone interested in how to do this repair already knows how to remove the pot from the pedal. Someone mentioned that a new improved pot was coming out. That would be great for the fellows who can afford to pay for them this post is mainly to help you fellows who have trouble affording to pay for the overprice pots. And the others that just don't like paying for something they can repair. Okay we'll get to the step-by-step guide, it will be a little lengthy. I hope I can explain this to were you can understand what I'm talking about. This is the way that i do this repair, I know other fellows may do it different but this is the just way I have found. The first thing I do is turn the pot upside down and make a reference mark on the back to line up with the middle solder lug. This is so you won't put the back on wrong when reassembling the control. The next step turn the pot up and take a knife and pry the four little tabs that hold the back on. Now with the back off Mount the pot in a vice with the shaft down, be careful not to damage the threads, be sure the only thing you you are putting pressure on is only the shaft and not very much at that. Now the next thing you dois inspect the resistance track to see if it's good and smooth with no scratches. If it is okay go to the little arm that holds the brush that rotates on the resistance track. Slip some type of plastic under the spring-loaded arm raise it just enough to remove the little brush from the holder. I use a needle to pryit out if necessary, putthe little brush aside so you can see it later to compare it with the one you are going to make. I make the brushes from alternator brushes orelectric motor brushes thay are all the same material, called carbon graphite. You can buy the brushes at any automotive supply house. Are you can go through a junkyard and get an old junk alternator you take this brush and cut a piece off of it about a eight of a inch square. Now you take a pair of either needle nose pliers are sharp pointed tweezers to hold the little brush block so you can work it back and forth on apiece of sandpaper to the right size to fit and the brush holder where you remove the other small brush, let the brush holder arm back down on the the resistance track, then put the back on press down the little tabs that hold it on and you're ready to go. You can check it was a ohm meter preferbly one with the hand rather than a digital if the hand moves smoothly from one side to the other you've probably done a good job. I hope you fellows that try this have good luck. These things that doctors use to sew up patients with or real good to hold the little brush when you are using on the sandpaper that's what I use you can buy him locally of medical center or maybe get one from your doctor I think they are called hemostats.

I took the liberty of making this a bit less Joycean:

"The first thing I do is turn the pot upside down and make a reference mark on the back to line up with the middle solder lug. This is so you won't put the back on wrong when reassembling the control.

Tim I want to thank you for cleaning up my post of the repair of volume pots, it sure makes it easier to read the post. I have only been a member of the forum for three months, and just turned 87 years old so I have a lot to learn about posting topics. Maybe your cleanup of my post will prevent anyone else from harming their eyes the way the Ontario Canada clown with the crossed eyes problem. I sure hope he recovers soon, again many thanks for your help Willie Sims.
