[CAUT] add capstans to tray?

[RicB]

Hi Mark...

I cant speak for any article on the subject... but the Yamaha Academy at 
Hamamatsu teaches that the reasons for capstans is to assure that each 
hammer lifts at exactly half blow. Since at the time they only had this 
feature on CF III's and I was at masters level I only had this shown to 
me quickly and only then because I was ahead of pace enough that they 
bothered to run me through it.

One set samples for each section so that the damper lever started in 
motion with the hammer at half blow for all samples.  Then one leveled 
the capstans with a straight edge from below.  At that point we were 
taught that these were not to be adjusted again unless it was to 
re-level the entire set of capstans.

They were NOT to be used to fine adjust damper lift from the strings. 
This was to be done as normal by loosening the damper wire screw and 
raising or lowering the damper as required.  They were very adamant 
about that.

Cheers
