William As Ron and Dale indicated, sooner or later all the agraffs are going to pop. I would suggest you have a meeting with the music people at this church and explain the situation. Be sure they understand that this is not your fault, and maybe not the fault of the other rebuilder. It's just one of those things. Hope they understand that replacing the agraffs and restringing the piano is still a hell of a lot cheaper than buying a new 9' grand. While you're at it, did the other guy replace the pin block, too, or just go with bigger pins? This might be an opportunity for you to do all of it right.

I suspected (correctly) that an agraffe had snapped. So I replaced the agraffe, put on new wire, repaired the damper, etc., etc. Now it's September and I'm tuning this same D (which has neared A=444hz with the end of summer humidity, and while I'm lowering pitch on D3 - WHAMMO!! Talk about getting the adrenaline going! So now this D (1927 - rebuilt by another tech some years ago using the original agraffes) has two popped agraffes; both snapped off at the stem just about 1/16" to 1/8" below the plate. Anyone have anything like this happen? I guess I don't really have a "what to do" type of question, just musing aloud as to the why's and what-if's. -- William R.
