If the hammer bore is too short, raise the whole stack instead of the hammer rail. Measure along the "Magic Line" to see if this relocation is viable.

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. I didn't catch whether someone else might have suggested another = possible/likely source for the problem: Perhaps the knuckles are = flat??? >>However, Ric is right.

What this would be achieving would be shifting the useful adjustment = range of the letoff button. The loss of a couple of mm 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. If indeed there is inadequate aftertouch, then the 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. 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??
