what you are suggesting - I remember enough of high school geometry to

hammers are hitting the capo.</FONT></FONT></DIV>

<DIV>When you say "clearly the action is too far forward"...how did you come
to that conclusion?</DIV>
<P>Did you experiment but lifting the keyframe at the front to tip the hammer
back in a bit? That would tell you if that is the problem...I
think IF the action does need to go in a bit...planeing the back of the key
frame is doable, but the cheekblocks are not going to move and
neither is the fallboard...make sure you have space between the sharps and
fallboard...really, I'm thinking the best thing to is to rehang the top two
sections with more of overbore to get them away from the capo...</P>

<DIV align=left><FONT face=Verdana>Older Kawai grand. The piano lacks tone in
the top two octaves - progressively gets worse toward C88. Cearly, C88 is
hitting the string at the capo - clearly the action is too far forward.
However, the key bed has three or four wooden stop blocks screwed to it that
prevent the action from being moved further back (what are those blocks
called?). I have not run into this before. What is the best fix? Removing,
plugging, and redrilling the stop blocks would be difficult in the cramped
quarters of the action cavity. Should I just carefully plane/cut off a few
millimeters from the rear rail of the action frame and then position with the
adjustable thingees (what are they called?) in the cheek blocks? </FONT></DIV>

<DIV><FONT face=Verdana>Seems to me it's one or the other. Any better
suggestions? Thanks.</FONT></DIV>
