<HTML><HEAD></HEAD> <BODY dir=ltr>The height is determined by the height of the tip of the tail of the hammer at let-off. The tip of the tail should be roughly even with the top of the backcheck at the point of let-off. Some prefer it 1-2 mm higher.

It does not<BR>take long, and it is not hard to do at all. There is another added<BR>advantage in that you can change the height of the back check to customize<BR>it to the hammers. Having the back checks at the right height for the<BR>individual piano will improve the checking. <BR><BR><BR><BR>Will Truitt<BR></FONT></DIV></DIV></DIV></BODY></HTML>
