The cost of replacing the block on this piano is not worth it. Even putting in plugs are not going to be cheap, either. It's sounding more and more that the best solution to this problem is a new piano.

Good point. I would think that drilling out the hole to accept the plug would remove any silicone-contaminated wood, but it would perhaps be hard to guarantee. ? Maybe it would depend a lot on how much silicone got in there. I just re-read your post describing what Phil Glenn said. Seem like he said that the silicone actually seeped some inches through the block to the bottom row of tuning pins. Hard to imagine that. But if that is what actually happened, then sounds like you're right - bonding anything to silicone-contaminated wood may likely be problematic. ? Heck, it might be a problem trying to glue in a new block! ?

Or, if the rest of the block seems good, maybe plugs in the affected areas. ? Terry Farrell ----- Original Message ----- I ran across this phenomenon a few years ago. Phil Glenn, formerly with Young Chang, told me that in the late 80's the drill bits YC used to pre-drill for the pressure bar screws were changed to a slightly smaller size. They later discovered that the guy putting the screws in put silicone on the screws so he could drive them into the smaller hole. Consequently the silicone creeped up the pinblock and typically the bottom row of holes of those pianos?would become loose. ? CA probably has the best chance of extending the tuning life of the Young Chang-built?Weber. Replacing the tuning pins or driving them deeper won't help. The only real cure is to?remove the silicone, which would require removing the pinblock. Best regards, Dave Davis, RPT -------------- next part -------------- An HTML attachment was scrubbed...
