This is a multi-part message in MIME format. ---------------------- multipart/alternative attachment Hi Tom, In a pinch one can slip a piece of sandpaper between the dampers and = pull out a few times to get the dampers to clear. I have used this idea = on drop actions where I did not want to pull the action. On these I used = a 1/32" X 1 1/2" X 8" steel file that I purchased at a convention = years ago for hammer shaping. Two grits on the same side on different = ends, 80 and 120 or so.

Bottom 5 or 6 dampers won't dampen. = They seem to descend slowly...except when lifted by the damper pedal. = Then, they all plop right down and dampen just fine. Upon further = examination, I find that if I hold the adjacent dampers away, I can get = any of them to dampen just fine when lifted by the key. Looks as if the = damper felts are in contact with one another, and when lifted singly, = the friction from the adjacent damper felt is enough to slow its descent = and make it not dampen properly. These are monochord dampers, and = through the ages, I think they've spread a little. (It's happening to = me...why not a damper felt?) Assuming that this is the proper diagnosis of the problem, what would = you recommend using to narrow the offending damper felts? Some = possibilities in my feeble mind include: 1. Using sandpaper to file them. 2. I don't think I could razor blade them neatly enough... 3. Ironing them...? 4. Squeezing them with a pliers. 5. Alcohol and a heat gun. 6. Just a gun. (Aimed at my right temple. That'll stop those = bass strings from ringing!) I'm pretty sure that I've correctly analyzed the problem, but can = anyone think of another reason these dampers will dampen as a group, but = not individually? The damper rod is not holding them too high. They = are not misaligned. There is not much follow through, but they dampen = fine as a group. There is sufficient lift of the dampers from either = the pedal or the key. =20 Thanks in advance for any ideas, suggestions...or guns.
