<DIV>If the glue will soften with warming from a heat gun, you can gain up to about 1/8" by warming the joint and pushing gently with hammer head removing pliers. Takes about 1 minute per hammer.</DIV>

<DIV><FONT face=Arial size=2>Hi Roger - I don't think the hammers have been filed - doesn't look like it. Yeah, they are definitely over-centering. We'll see what $$ will allow me to do - mom & dad don't play and junior is just starting lessons. I thought she being willing to do a full action regulation to correct the 12 mm let-off and 3 mm aftertouch was about as far as I could push her........</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Thanks for the ideas though. I suspect this piano is 30+ years old and the hammers have a fair bit of wear on them - I'd hate to spend much time ($$) perfecting an old hammers like that. We'll see.</FONT></DIV>

<BLOCKQUOTE class=cite cite="" type="cite"><FONT face=Verdana size=3>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?<BR></FONT> <BR><FONT face=Verdana size=3>Seems to me it's one or the other. Any better suggestions? Thanks.<BR></FONT> <BR><FONT face=Verdana size=3>Terry Farrell</FONT></BLOCKQUOTE><BR>Terry,<BR><BR>I my first year of piano work, working at Sydney's distributor for Kawai, we regularly moved the action and keyboard assembly back to correct for strike ratio problems in the high treble.
