Gentlemen, I believe it's already been done. I could be wrong, but if my memory serves, Herr Steingraeber has already designed and fabricated a rolling knuckle. Anyone know if I'm remembering the right/wrong thing?

Why not use little rollers instead ? You must mean "NOT be able to push" up to the string. I think that a stronger spring to push the jack towards the roller, and the tip of the roller being shaped like a jai-lai paddle would prevent any premature tripping. If you build it and get rich, just send me some royaties, please.
