[pianotech] Keyblock/frame bedding problem

[David Skolnik]

Daniel -
If I understand your description, then I don't think anyone has 
actually addressed your question.  First up, it would be possible, 
though unlikely, that, even with the key blocks out, you could be 
knock-free.  That would depend upon whether the underside of the 
front rail is relieved at the ends, to create a positive flex when 
the blocks are tightened down.  But you're saying that, even with the 
blocks installed, the keyblock plate, which in the Kawai is made of 
plastic, is not bearing on the keyframe pin.  And not by a 
little.  You're talking almost 1/8". That's a lot.  Isn't there an 
adjustable component to that plate?  I don't think it's simply a 
solid piece of plastic, eh? Take a look.
