<DIV><FONT face=Arial size=2>You mean to raise the entire action =

so??? That's quite a lot! I thought you were just talking =
about 1-2
mm elevation in the hammer rail. Perhaps a better solution, if =
shimming
*must* be done, is to shim only under the rear supports, so that the =
action
stack tilts slightly towards the keyboard? This would elevate the =
hammers
much more, for less change in the overall position of the =
stack.</FONT></DIV>

<DIV><FONT face=Arial size=2>What this would be achieving would be =
shifting the
useful adjustment range of the letoff button. The loss of a couple =

of material would be completely inconsequential if indeed the letoff =
buttons
should be adjusted where they are now. The only way this would be
"disastrous" would be if the letoff buttons need to be adjusted =
*downwards*
to their full extent, in which case a useful 2 mm of range would be =
lost. This hardly seems likely.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>If indeed there is inadequate =

wippens are probably sitting too low; hence, the hammer rest position is =
probably too low. Why not raise the capstans, setting a higher =
hammer rest
position? Sand the letoff buttons to adjust higher, and set the =
letoff at
1/16". If you can't get a normal power stroke out of this action, =
it seems
it would have been designed with the wrong geometry, no? I doubt =
Schimmel
does such things. But if all this is true, the buttons still =
require
sanding.</FONT></DIV>

<DIV><FONT face=Arial size=2>However, cherchez les knuckles! =
If the action
was ever "right" with the world, then the buttons probably had enough =
adjustment
left in them to yield proper letoff -- perhaps only barely. Now =
with
flattened elderly knuckles (??), the letoff cannot be adjusted high =
enough. Plausible theory??</FONT></DIV>
