<html> <body> Terry, Steinway calls them DAG blocks and recommends adding veneer/planing-off of the key-frame if adjustments must be made.  (Remember the una-corda/shift-pedal.)  Presumably Kawai key rails aren't adjustable, don't have one here on the floor to look at. Good luck, Andrew Anderson At 04:06 PM 9/1/2006, you wrote: <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></body> </html>
