Except in the case of the Amherst piano, a Canadian one. They are notorious for loose pins, and I believe it was determined, that they speeded up production so much that the pinblock wood was not properly cured. Cured, that is not the word is it?</FONT></STRONG></DIV> <DIV><STRONG><FONT face=Arial>Can you see the top of the pinblock?</FONT></STRONG></DIV> <DIV><STRONG><FONT face=Arial>Just a few pins, go with oversize to try.</FONT></STRONG></DIV> <DIV><STRONG><FONT face=Arial>As for doing it all with #4, try a few, and see how they hold, before committing yourself. Oh yes, the looseness up here, sometimes does not show up till, Jan/Feb, when the humidity can be down in the 20%'s.</FONT></STRONG></DIV> <DIV><STRONG><FONT face=Arial>Regards,</FONT></STRONG></DIV> <DIV>John M.
