Re: Removing Old Tracker Bar Tubing
By Bob and Sonja Lemon
In Digest 961213 Bruce Hannover wrote about the 1922 Gulbransen Player Piano which he is rebuilding.
There are a couple of ways to remove that old rubber tubing. I use round jaw pliers (not round nose). Insert one jaw in the brass tube of the tracker bar, pinch over the rubber tubing, release pressure slightly and gently twist. NOT TOO HARD! This will shatter the hard rubber tubing, the twisting will remove remaining residue. For soft rubber tubing that has vulcanized itself to the brass, the pliers will cut through and the rotating motion will peal most of the tubing from the brass nipple. The remainder can be removed by soaking in lacquer thinner and brushing off residue.
I hope you have done your homework about this player action. It is one of the hardest to rebuild accurately. There are several pitfalls for the inexperienced.
Have you removed the pneumatics yet? We have developed a method of removing pneumatics with minimal damage to either the pneumatics, wooden valve caps or the decks. We also have a different system for disassembly and reassembling of the stack. It does not require the use of gaskets and virtually guarantees that there will be no plugged or leaking air passages. If you are interested we will explain our system.
