Regarding repairs to pin block with epoxy, I have had some experience with slow setting epoxy, veneering the top of open pin blocks. If epoxy gets in contact with the pins though, expect trouble - there'll be some snap crackle and pop. Epoxy can really do wonders in many applications where penetration or saturation is beneficial. I've been tempted to flip a grand onto its top and attempt an epoxy repair to the underside of a block, but haven't yet. Ralph Thorn London, Ontario CA
