these holes (and the screw holes if there are any), and redrill in the =

size=2 FAMILY="SANSSERIF">Hello All, <BR><BR>I often run into =
grand pianos
with keys rubbing on the keyslip. I have tried <BR>various =
methods for
repairing the problem, but would like to pick the <BR>collective minds =
of the
fine folks on this list. <BR><BR>In the past I have tried shimming the =
keyframe with front rail punchings. I <BR>have also tried a =
screw in the
keyframe. First I check the strike point on <BR>note #88. =
If I can
improve the tone by adjusting the cheek block hold downs <BR>I will. =
<BR><BR>My problem with shimming is, if the customer wants to use the =
una
corda <BR>pedal, there is sometimes too much friction for the action =
to return
<BR>properly. I guess the correct solution (I may be wrong), to =
this
problem is <BR>to slide the stack forward drill and plug holes. =
Thus
allowing the action to <BR>"retreat" into the action cavity. Now =
I have
a birdsnest of other problems <BR>to contend with. Cheek blocks =
need
adjustment, capstans may be too far back <BR>on whippen heel, checking =
will be
off, possible damper interferance just to <BR>name a few. <BR><BR>Now =
you all
have run into this problem. I know. Please don't tell me =
"Well
<BR>I'd just plane off the back of the keyslip" or "a little sanding =
on the
front <BR>of the keys will do wonders". Those are not the types =
of
responces I am <BR>willing to entertain, thank you. I also =
sometimes
find a warped keyslip, <BR>lets deal with that one another day. =
Lets
correct the straight ones first. <BR><BR>This will probably seem like =
a simple
fix type problem we deal with everyday, <BR>but I am curious about the =
"correct" fix. If I left out some of the small <BR>details, use =
your
imagination. <BR><BR><BR>Thanks in advance <BR><BR>Mike Bratcher
