Need Some Input

[Paul T Williams]

On #2;  I've also had the squeek come from the balance rail hole on the 
bottom of the key.  Remove the key and clean out any gunk, polish the 
balance rail pin with Flitz and see if that helps, too.

# 1: It's more likely that the hammer butt felt (the little rectangular 
piece that the jack tip rests on) is either missing, or has a smidge of 
hardened glue on it. Replace if missing, or clean the glue off the contact 
surface.
#2: Probably the balance rail bushing (if it's the front rail these 
suggestions apply equally). Microfine teflon powder &/or Protec will quiet 
it right down. It's possible the problem was caused by glue soaking into 
the felt when the key was bushed (plus a certain amount of wear).

I was working on my piano this evening, and I noticed two problems, and I 
wanted to get some input before I proceed.
 
1.  When I play one particular note, I hear a clicking sound.  It is from 
the action, not the key.  I believe it is the jack rubbing against the 
underside of the butt, and the buckskin in worn off.  When I pull the jack 
back with my screwdriver and release it, it does make the same kind of 
sound.  And when I press down on the key, wait a few seconds, then release 
it, I hear it too.
 
2.  On a few notes I hear what sounds like a faint squeak.  I believe it 
may the front rail pin rubbing on worn bushing cloth underneath.
