[pianotech] Best way to change touch on Yamaha Grand

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
