Not sure I understand what you mean here. Putting aside the jack knuckle interface angle, why would the advantage of shimming out the wippen be lost at the knuckle?

Shimming out the wippen flange will also accomplish the same thing without having to move the stack. Moving the wippen rail is only to align the centers. There is no leverage gain as one might think by moving the rail back because the advantage you gain in regards to the capstan is lost at the knuckle. Whereas moving the stack back increases the input dimension without increasing the output thereby lowering the ratio. -- Regards, Jon Page -------------- next part -------------- An HTML attachment was scrubbed...
