<HTML> <HEAD> <TITLE>Re: Protek & Teflon</TITLE> </HEAD> <BODY> Ken,    My guess is that the Protek had little effect on the ham= mer shank flange  friction, and that your improvment came about with th= e knuckle resistence reduction.  The teflon bushing on a 72' S&S wh= ich has not been repinned, should be low to begin with.    I apply the teflon powder to the front key pins, and the= sharp key pins also, (lift up the action to access the sharp front key pin = backs)  and brush it on with a 2" high quality natural bristle (ch= ina)  paint brush. If you are a complete fanatic like me, you will also= find that brushing the balance rail key pin tops, will allow enough teflon = powder to work its way to the friction points of both the bushings and the b= ottom hole.    Furverent adherants will also brush the exiler onto the = key end felt, which will reduce the friction at the underlver/key , and whil= e the action is @ 90 degrees to the bed, one can treat the key frame contact= points, una corde slot, and with a determined reach, the dags and return sp= ring. Did I mention the frame pins? PS  A slight reduction of down weight can also be secured by setting t= he jack to knuckle position a little lean. Comprende?
