>My question for those who suggest that I check hammer bore vs. string >height is, what am I looking for? The height of a hammer center pin above the keybed plus the hammer bore distance should be very near the string height for that note. If the hammers have been filed deeply, or mis-bored, they may be too short. If so, they should be replaced. Also, how do the knuckles look? Are they badly compacted? The idea is to try and determine exactly where the problem actually is before you go fixing yourself into a corner (as we've all done) by changing the wrong thing. Ron N
