I agree with Ron that there's no evidence to support the notion of a "moisture barrier". But a real problem is allowance for the pin if one needs to drive it further in over time for increased torque as the piano ages. A "through" block seems to be such an elegant and manipulable structure, and there really is no reason to be tricky about it.

While tuning an old Baldwin Grand from the thirties I pulled the action and for some reason touched the bottom of the pin block. It was not drilled all the way through! I don't think I have ever noticed a shallow drilled grand pin block before. This got me to thinking about reasons why someone would drill this way? I came up with 0! This was a pin block installed by a technician here in the area. He is not on this list and to be truthful I don't think much of his work. So maybe its just one of those odd jobs that a less skilled technician would perform? Or maybe its a common method used on grand pin blocks and my blind a-s just don't know it? The grand blocks that I have dun, or helped do were drilled all the way through! So you guys tell me. What gives? Thanks! -------------- next part -------------- An HTML attachment was scrubbed...
