Yes, I was talking about Grand pin blocks. Some of you who haven't even taken a piano COMPLETELY apart are casting dispersions. I think that's being rather granular. The main point I was trying to make was that SEALING the entire pin block should improve it's ability to repel wild humidity changes and last longer. As for Uprights "not being drilled all the way through", is utterly stupid. No they are not drilled all the way through, (although there are some that are), the point is that they are not finished in any way and are therefore more susceptible to drawing and letting off moisture more rapidly = failure of the wood.
