[CAUT] Which S&S replacement action parts?

[Paul T Williams]

Fred,

I find the most complaints from pianists is that the touch is as I put it, 
" equally inconsistant"!  If I only have an hour or so, I find the best 
note and quicly match that let-off, drop, after-touch ect. to get 
something close as long as it's equal.  This usually pleases the guests. 
then after that, I go in the next day or whatever and fix what was really 
the problem.  Most of the time, it is something simple.  Although, 
sometimes,  it has awakened the beast!

Hi Dave,
                 Yes, I agree, evenness is king, whatever the parameter. I 
had that 
thoroughly hammered home for me a couple days ago while doing a 
recording session (ie, me playing the piano, which I had, 
unfortunately, prepared - I hate wearing both hats for a specific 
gig). I had a section of about two minutes where there is a constant 
pianissimo trill done by the index finger and thumb of the right hand, 
while other fingers and hand do other things. I couldn't get the trill 
to sound or feel even, though I had been quite successful at it in 
rehearsal/practice at other instruments.
                 I pulled the action and looked at the two notes. Sure 
looked pretty 
darned even to me. I looked closer. I ended up changing letoff, drop, 
and jack position relative to knuckle less than 1 mm each, changed dip 
of one note by .010", and did a wee bit of needling on one hammer 
(most of the problem seemed to be the relative feel of the jack 
rubbing the knuckle during letoff). And I was successful in pleasing 
myself. But it sure did reinforce the idea that you  can't be too 
obsessive in pursuit of evenness.
                 BTW, this kind of trill really accentuates things, 
because the keys 
are moved the tiniest amount possible - allowed to rise only enough to 
re-engage. Check doesn't enter into the equation, as the key is 
released before there is a chance for the tail to hit the check - at 
least I think this is true, I'd have to see high speed videography to 
be sure. I think absolute evenness of aftertouch is the biggest factor.
