I started with the top section and then started to reinstall them. After r= eplacing a few, I was shocked to find that they were still very tight. No, t= hey can't be. If anything I pinned them a little on the loose side. While mo= ving a wippen up and down I slowly loosened the screw to find the looser the= screw got, the freer the center felt.   Well its getting late so I w= ill deal with this tomorrow, but the only thing I can think of off hand is t= hat the flange and the rail are not mating well and tightening the screw is = distorting the flange and forcing the "legs" together causing binding on the= wippen. Does this sound like a good guess? Anyone run into this? Best cure?=   The irony is that the flange= s may not have needed to be repinned in the first place. When ever I had rem= oved one after treatment to check it by hand, it usually would not feel too = tight. Hmmmm....well its getting repinned anyway which is still probably bes= t for the long haul, if I can get rid of the binding problem.   Dave Bunch </BLOCKQUOTE> Dave Would you believe I just got done working on a Wurly console with the same p= roblem. 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 fl= anges, that when you tighten the screw, the centerpin will actually push aga= inst the centerpin of its neighbor, and bend a little. That is what is causi= ng the wippen not to work right. When I was in the process of solving the problem, I noticed that when I inse= rted the pin with the pin removing/installing tool, the flange is being push= ed to the side where the pin comes out. There is a small gap between the fla= nge and the wippen base. This makes the pin just a little too long. To remedy this problem, push the flange back against the wippen base, and th= en cut off the pin. If you go to one where you've already cut off the pin, a= nd 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. 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 re= pin a number of jacks too, even though I lubed the hell out of them. Unfortu= nately, I had to do the jacks at the customer's house, because you can't rea= lly tell if the jacks are tight until you get the action in the piano. Good luck Wim </HTML>
