[pianotech] Best way to change touch on Yamaha Grand

[John Ross]

Why not change balance, and front rail punchings to bring the balance back.
Or is that too simplistic?

  Thank you for your answer, Patrick!  The key recoverer has been doing this for many years, although I have only used him this one time.  The keys look beautiful . . .  He will not remove the keys to plane the tops.  Instead, I have been told to remove wood from the bottom of the white keys with a belt sander to clear the black keyframe felts.  This solution makes me sick.


  I guess I will go ahead and add the thicker blacks so that the keys are at least even with themselves, even though not at spec.  I suppose that if I choose the highest possible key height, that the keys will be close to their original position.


  Do you think there is any problem with that?  Am I right to be concerned?  Or just being too nuts?


  BTW, I didn't really understand the process of changing the key weights by trimming glued on balance rail felts.  One of the very last posts of that thread seemed to contradict the others, and nobody picked up on it.  Maybe I should just disregard that issue, which is causing me the concern now.


  Thanks again.  Now I know why I drove all the way to Welles ME for all those years!  I never saw this problem until now.


  Thanks,


  Denise

    Denise, 
    Why is the key recoverer not willing to correct the mistake? Did you select the option of a thicker plastic, assuming your vendor had enough sense to remove enough wood to keep the thickness of the wood + top at the original spec? Has this vendor been offering this service for weeks or years?
    Oh well ... redundancy (check & double check everything) has its virtues.
