My trainer/mentor told me about a drop-action problem that the rubber ring on the back of the key was so dry that it was knocking. Is this a possibility ? >>>I came across a new one today, I think. 1983 Everett school model >>>studio piano. While tuning I would hear a woody-sounding click on >>>nearly every note, very consistent, similar to the sound you get if a >>>jack tip lost its felt. Nothing I checked seemed to diminish the sound >>>until I took a length of 1.0mm center pin bushing cloth and held it >>>where it would get sandwiched between the backcheck and the catcher when >>>the key was depressed. That squelched the noise markedly. The >>>backchecks have only 1/8" or 5/32" of felt, which is not all that >>>unusual, I guess, but it seemed pretty hard to me. >>> >>>So I think what I need to do is replace all the backchecks, but because >>>I've never run into this before, I'm asking if anyone has ever had to do >>>this on a piano only twenty years old. Is this indeed the problem, or >>>does it just *appear* to be when it's actually something else? Thanks! >>> >>>Regards, >>>Clyde >>> >>> -- Duaine Hechler Piano, Player Piano, Organ, Pump Organ Tuning, Servicing & Rebuilding Associate Member of the Piano Technicians Guild (314) 838-5587 dahechler@charter.net
