<DIV>The problem is that there is too much weight in the front of the =
keys for
the weight of the action and spring tension combined to push the key =
back into
place no matter how much lost motion I take out of it (I removed all I =
should
have needed to and then some). This is not a garden variety =
regulation
problem, unfortunately. </DIV>

be
irrelavent, but assume <BR>this is an upright.<BR>Hence hammers =
should not
be of the rail at all, and jacks should not have to <BR>force =
themselves
under hammer butts as a gap should exist for this. Even in a =
<BR>grand the
jack doesn't support the hammer roller, so regulation is at =
fault.<BR>Bruce

("free") tuning presented a plethora of problems(Am I almost =
