Hi Emerson and Welcome to the list! Some grands have a "floating" block. My first rebuild was a 1919 Chickering quarter grand and it had a "floating block". I don't recommend to anyone to tackle a Chickering as their first major project! That was fustrating to say the least! I don't know about McPhail's, but somebody on the list sure will. There's also a lot of block-drillers that will know a good bit speed. My shop is limited, so I always outsource pinblocks and soundboards and refinishing. Good luck!

I must start by saying I am new to this list as well as new to rebuilding piano’s so please excuse my ignorance. I am rebuilding a 5 ft. McPhail grand and have a couple of questions regarding pin block drilling and installation. The new pin block material is DELIGNIT PIN BLOCK material and seems to me to be the hardest wood known to man. I am curious if anyone out there has a particular speed setting for the drill press and how different speeds affect the size of the hole. Currently I am using #2 pins and a .266 drill. Another question would be do I need to glue the block in? I don’t believe it was glued previously. Thanks Emerson Torrey -------------- next part -------------- An HTML attachment was scrubbed...
