This is a multi-part message in MIME format. ---------------------- multipart/alternative attachment Hi Robin: An old axiom that seems true goes: " Fixing a problem is easy once = you know what it is...finding it is the real problem." One way to = narrow it down is by moving the pedal when the squeak is present and = listening to various parts of the trapwork and action with a long rubber = or plastic hose. One end is in your ear, the other is directed to the = suspected trouble points. A mechanic's stethoscope with a metal probe = end is also helpful to locate squeaks. By carefully touching various = parts as you press the pedal may lead you to its source. Diagnosing = the noise when it is there is your best hope of nailing it down. After = it is gone, you can only wait and hope it doesn't return. Another way = is to carefully duplicate the movement of the pedal at various points in = its train of motion. Start with the long horizontal transverse wood or = metal piece connected to the pedal itself. If the sqeak is gone, back = up one step to find the reason i.e. the pedal itself or the threaded = adjustment rod. If it is still there, push up on the vertical rod and = see if it remains. If not, back up and you're there! Maybe. What = you're trying to do in all of this is isolate and define the source of = the noise. The two major divisions are trapwork and action. Once you = know the area the sqeak is coming from, you're one step closer to the = final answer. =20 One thing is guaranteed after you reach a conclusion, you will never = forget it! Hope this helps....

This will be my second callback on = the problem. At first, the noise seemed to be coming from a bit of = debris between one of the spoons and the lifter rod, but a few hours = after I left, the problem recurred.

At first, it sounded like = it was near the pedal rod to action connection, but then it seemed to be = at the pedal itself. I took the pedal bracket apart and lubricated the = pins and tightened everything down. There seemed to be some space = between the pedal rod and the plastic bracket allowing some movement, = but not enough space to insert even a thin cardboard punching. I = thought I had really found the problem in the metal ring that connects = the pedal and trap lever. I lubricated every moving part I could find = with either Protek or Prolube. I played the pedal about 400 times, had = the customer play a couple of songs, and the squeak was gone. We were = very relieved. Yesterday, two weeks and one day since my last visit, = the customer called complaining that the squeak is back. I would = appreciate any and all advice for my appointment with her tomorrow = either via the list or to my email account, LadyPianoTuner.com. Thank = you one and all.
