<div> <font face="Arial, Helvetica, sans-serif">So he did. And that's already excessive. I'm not sure though whether that reflected an even dip throughout the compass, or if he had established that in the bass only in order to try to get aftertouch or even escapement. My point if there was one was to create a baseline. Obviously he needs to make sure that blow is set, but blow changes with key height, too. Is that as clear as mud? ;-)<br>

<div>You might check key height and level down through the bass. If you can
raise the keys slightly (shim under the balance rail), you'll get enough key
travel for jack escapement and aftertouch. Almost all "bobbling hammers" are
the result of too little or no aftertouch due to settling of the keys at the
balance rail. Generally, though, it's in the middle of the piano where it is
most played. Hmmm.<font face="Arial, Helvetica, sans-serif"> You'll then,
however, have to adjust dip, lost motion, and checking again. Just a
thought.</font><br>

Like
Terry said, decrease hammer blow distance. Then your problems (bobbling
hammers/heavy touch) are probably due to too-strong hammer and/or damper
springs...and it also could be too-soon damper lift. Also checking the height
of the balance hole with a balance hole reamer would be in order. OK, check
for too-tight balance holes and bushings, too. <br>
