Action Position Adjustment

[Mark Bolsius]

G'day Terry,

 

If worst comes to worst, the key beds on most Kawais isn't glued on, you
could take the key bed off and work with the dag block that way..

But as David said, make sure you have the clearance at the back of the
sharps for the fallboard.

 

Cheers

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,

 

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.
