David:...."Trying to get the pinblock screws out of the piano turned out to be quite an ordeal. They were completely frozen in the block and two of the longer screws (at the struts) sheared off. Is this typical behavior for Delignit blocks? Though I am going to replace the block, I have another question. Were I to reuse a Delignit block, what is the best way to approach the next tuning pin size. These were 2/0 and were fairly tight, though quite corroded." I would say this is not typical of Delignet. I think the clue is in your statement about the tuning pins......."quite corroded"! However, as I said in a recent post, I always "cut" the threads into pre-drilled pilot holes. Delignet is bit less forgiving of screws and such, IMO. Also, the person that replaced that block might have done something to make it impossible to remove the screws.
