So far no more knocking, but I'm to tune the piano again this week and = wonder if there's a more "professional" fix, or cure, for this situation.  = I'm speculating that if glides should be installed on the front rail or = keybed, this would alleviate the endblock situation.</DIV> <DIV> </DIV> <DIV>So, if anyone has had experience with this type of situation, I'd appreciate your advice.</DIV> <DIV>Thanks,</DIV> <DIV>Bruce Greig</DIV></BODY></HTML>
