Remove screw and blunt the end. = re-introduce the screw, then adjust the in/out of the key slip as you = wish.=20 Sort of like the way Wurlitzer used to do it, only coming in from the = other side of the front key frame. No having to go thru the hassle of = pulling the whole key frame assembly and shimming. Should be doable in 5 = minutes, assuming as I said, the key slip will flex with a little force. = Bet it will.
