<DIV><BR>I guess that's why I prefer Kawai's circle of refinement to
Yamaha's 37 steps, in the circle of refinement you are seeking to
regulate/adjust/refine as needed to bring the action to the point of
functioning properly rather than following a list of steps some of
which may seem/be superfluous. In the circle of refinement it is not unheard
of to repeat/redo and adjustment after performing some of the other
adjustments, it's considered another step on the road to refinement.</DIV>

<DIV><FONT face="Arial Narrow"> Yamaha has a "circle of
refinement" as well, tho' they may not call it that. If you attend the
Little Red Schoolhouse, in conjunction with thje 37 steps of
regulation, they also point out a Circle of 7 Steps which is a
circle of refinement to be performed after keys are leveled, parts aligned,
and the 37 steps have already been gone through to ensure that there is at
least some drop and at least some repetition spring strength. The 7
steps are: 1. Blow (hammer line), 2. Let-off, 3. Drop, 4.
Dip/Aftertouch, 5. Back check (checking distance from string), 6. Repetition
Spring strength ("hammer rise"), 7. Jack height (which is really Repetition
Lever Height relative to the jack, or "winking the jacks").</FONT></DIV>
<DIV><FONT face="Arial Narrow"> The last 9 of the 37 steps
(dampers, sostenuto, soft pedal, etc.) can be done after
this refinement circle.</FONT></DIV>
