<DIV><FONT face="Bookman Old Style" size=2>I was referring to the height of the
backcheck in the key.</FONT></DIV>
<DIV><FONT face="Bookman Old Style" size=2></FONT> </DIV>
<DIV><FONT face="Bookman Old Style" size=2>NY Steinway calls for the check angle
to be 68 degrees to the key, and there should be a 1/16" or about a 2mm gap,
between the top of the backcheck and the tail of the hammer when the hammer
is AT let-off. That is, 2mm before the hammer drops.</FONT></DIV>
<DIV><FONT face="Bookman Old Style" size=2></FONT> </DIV>
<DIV><FONT face="Bookman Old Style" size=2>If these things are correct, I'd see
if I can get some samples to check properly while I'm sitting at the piano,
pulling the action, adjusting, checking, repeating, ad infinitum. I don't
recall if you tried to set samples in the piano and then duplicated that on the
bench, or if you were just setting checking at the bench......??</FONT></DIV>

<DIV><FONT face=Arial>William, are you talking about the height of the
backchecks in the key or the height that I'm setting them at to
check? I have tried setting them higher and lower with not
much improvement.</FONT></DIV>
