anything I pinned them a little on the loose side. While moving a =

FAMILY="SANSSERIF"><BR>Dave<BR><BR>Would you believe I just got done =
working
on a Wurly console with the same problem. I too repined the flanges =
and then
had trouble with the wippen. The problem is the center pin is bending. =
There
is so little room between the flanges, that when you tighten the =
screw, the
centerpin will actually push against the centerpin of its neighbor, =
and bend a
little. That is what is causing the wippen not to work right. =
<BR><BR>When I
was in the process of solving the problem, I noticed that when I =
inserted the
pin with the pin removing/installing tool, the flange is being pushed =
to the
side where the pin comes out. There is a small gap between the flange =
and the
wippen base. This makes the pin just a little too long. <BR><BR>To =
remedy this
problem, push the flange back against the wippen base, and then cut =
off the
pin. If you go to one where you've already cut off the pin, and do =
this,
you'll see that there is a half a millimeter left sticking out. That =
is all
that is needed to bind the flange. <BR><BR>I hope this solves your =
problem.
It's only in the treble area. BTW, I reamed and repinned all the =
wippen
flanges. I used the Mannino reamer. I took out a .50 pin, reamed using =
a .51
brouch, and then repinned with a .50 pin. That worked best for me. I =
also
repinned all the hammer flanges, and I had to repin a number of jacks =
too,
even though I lubed the hell out of them. Unfortunately, I had to do =
the jacks
at the customer's house, because you can't really tell if the jacks =
are tight
until you get the action in the piano.<BR><BR>Good luck<BR><BR>Wim
