<html> <body> Hi Terry,                 Have the hammers been filed a few times, and are they now are over centreing? If key slip and key board cover all look good with the action,  pop the hammers off and hang them back a few mm's. If hammers are over centreing, ream the holes a little so can tilt them back a tad. I know watch out for some geometry issues =-O Regards Roger At 05:23 PM 9/1/2006, you wrote: <blockquote type=cite class=cite cite=""> <blockquote type=cite class=cite cite=""> 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?   Seems to me it's one or the other. Any better suggestions? Thanks.   Terry Farrell</blockquote> Terry, 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. Our solution was to plane a bit off the back of the keyframe also.
