[pianotech] Keyblock/fram bedding problem

[Daniel Carlton]

Hi David and others

Sorry for the late response. I'm always a little slow on the uptake.

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.

No.  No adjustment up and down. Mark Wisner at Kawai is sending me  
three-way adjustable plates (or two-way, or would it be four?). Once I  
put those in I'll do the bedding again.
