<DIV>Paul,</DIV>

<DIV>Roger is right but even with the universal wippen there may not
be any simple solutions that don't involve changing the spread, capstan and heel
location. The whippen rail is adjustable on older Knabes so you might be able to
compress the spread just wee bit, allowing you to align the jack
further back. Generally, they were set up between 4 to 4 1/2 inches. Be aware
that doing this will alter the geometry, regulation and touch weight, but it is
a great way to experiment and learn something. It is not difficult to reset to
th original and there should be small wooden wedges that mark the original
location and were meant to keep the rail from working its way forward. </DIV>

Paul,<BR>
When you have mismatched or incorrect parts, no amount of fudging will help
you. Sorry to be the bearer of bad news. You have done the right things in
checking the blow dip and after touch relationship.<BR><BR>The knuckle is too
large, and/or the centre pin to knuckle core is incorrect, and/or the spread
of the flange screw to centre pin is incorrect.<BR><BR>Try a variety of new
shanks, and install the correct shanks.<BR><BR>Regards Roger<BR><BR><BR><BR>At

<BLOCKQUOTE class=cite cite="" type="cite">Dear
Friends:<BR> I have a Knabe baby grand that has been
rebuilt/refinished with new wippens and shanks/hammers. The problem is
that that the knuckles push the jack into the cushion as it
rebounds. There's no room for the jack to move. Even if I
change the dip/blow distance, the problem is not solved. When the key
is fully depressed, you can't "wink" the jack with your finger because it's
pressed against the jack cushion in the window. The only thing I can
guess is that the knuckle needs to be moved away from the flange, or maybe a
smaller knuckle. The action feels "squshy". The piano belongs to
the store I work for, and I would like to make suggestions to my boss as to
what needs to be done. I hesitate to recommend a whole new set of
parts, but this thing isn't going to get better without them. I'm not
set up for rebuilding, and I don't do much action replacement, so I need
some feedback from you all to! help solve this problem. Any
suggestions will be appreciated.<BR>
