The teflon bushing on a 72' S&S which 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 (china) 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 bottom hole. Furverent adherants will also brush the exiler onto the key end felt, which will reduce the friction at the underlver/key , and while 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 spring. Did I mention the frame pins? PS A slight reduction of down weight can also be secured by setting the jack to knuckle position a little lean. Comprende?

It's a '72 teflon, and the downweight was around 70, upweight around 30 or so. I used Protek on an experimental hammer center or two and measured a 5 to 10 gram reduction in downweight. Has anyone run into this before? I lubed all centers and used teflon on the knuckles and all was well (all things considered). The pianist called to say how happy she was and what a miraculous job I had done making the piano playable again. What gives?
