>I'm sorry but the resistance arm of the wippen is to the jack center pin. Then YOU tell these guys that they're wrong... (pdf attached) I have moved many a wippen rail and not had a minimal difference in touchweight or friction. But move the stack by the same amount and you'll notice a difference. Moving the rail aligns the centers, moving the stack alters the Wippen Ratio. Moving the capstan alters KR and Wippen Ratio. So when relocating the capstans is not viable, look to the stack. I offered this option since we were speculating (lacking more info) on treatment of these actions. When regulation or mass alteration does not accomplish your goal then look a little further. One sign might be shanks which are not centered over their rest cushions or wips in the bass and low tenor. Once the stack is moved (usually back) the realignment of the hammers to the strings also places the shanks more centered on the rest felt. To me it's just another overlooked aspect. -- Regards, Jon Page -------------- next part -------------- An HTML attachment was scrubbed...
