(Maybe a good idea to shellac the block, too: on all sides.) <br /><br />Thumpe</div></td></tr></table> <div id="_origMsg_">

I am of the opinion that it isn't a problem on the blocks I have direct experience with. Some of these pianos I am talking about got their blocks in the early 1980's. If I don't see any appreciable lateral movement of the pin through the block after 30 years, I am not going to let that be a determining factor in my technique.<BR>Ed Foote RPT<BR></td>
