I'm not talking about the overlapping holes, you can simply plug the old ones. Flipping the angle will move the capstan contact point on the key well away from the balance rail reducing the mechanical advantage considerably (assuming the contact point on the wippen heel remains the same. Likely you would not have room under the heel to maintain the same capstan/key contact point and have the top of the capstan centered in any way under the wippen, if even contacting it at all. You could, of course, cut off the wippen heel and relocate it, you would then have to recalculate the new wippen lever ratio into the equation.

That's pretty much what I had concluded. I was content with the SWR about where it was, and there was no need to reposition the capstan. Flipping the capstan angle while preserving the position of the head would result in overlapping holes.

Flipping the angle the > other way will likely result in a rather high overall action ratio. You mean because of the contact point on the capstan being in the middle of the head, rather than on the far edge??? Ah well... It's not something I'm burning to do. ;-) Peace, Sarah _______________________________________________ pianotech list info: https://www.moypiano.com/resources/#archives
