Ed fixed a Baldwin today, I fixed a Yamaha. You know the pedal lever mounted on a block, with a coil compression spring holding up the pedal. When the pedal was depressed, at a certain point, the spring was compressed enough that it became the lever fulcrum and the leverage lifted up on the hinge, causing a click. The nylon bushings in these hinges work great as long as the pressures exerted are always in the same direction, but when the pressure direction changes, there's nothing I have come up with that keeps them quiet. The fix was to take the spring out, haggle a couple of turns of the coil off with my poor old abused side cutters, and put everything back together. There was still enough expansion pressure to hold the pedal up so everything works, but not enough to lever the weight off of the hinge at full depression. Worked great. As I was trying to cut through the spring, I was telling the customer that "I hope this works", trying to sound concerned, "since I can't go back". She was duly impressed when it was back together and worked quietly, but I'd tuned for her for a couple of years, and had done other repair work for her, so she really wasn't worried as I wrestled the spring around the floor. Beautiful day today too, up in the sixties after Tuesday night's snow... or was that last night? Good grief, is it Friday yet? Ron N
