Are you aware of a source for plated key pins for Yamaha - = front rail =3D 0.125-inch and center rail =3D 0.137-inch? =20 Terry Farrell ----- Original Message -----=20 =20 Hi Terry, If you are going to rebush, why not also repin with the better pins, = and use leather the correct size. Then you will not have the = contamination problem with the Ballistol. Joe Goss RPT Mother Goose Tools imatunr@srvinet.com www.mothergoosetools.com ----- Original Message -----=20 =20 I've got a bunch of Yamaha C3s from cruise ships to do key bushings = on. Many of these piano get fairly rough use 7 days per week (piano bar = and all that). So we're searching for a better way. Some of these get = worn out in a matter of several months. =20 We've considered leather bushings, but my understanding is that there = can be a chemical reaction between the leather and the Yamaha brass key = pins. I don't see that the supply houses offer plated/steel pins in the = Yamaha size. =20 So maybe we need to use cloth key bushings. I heard from some that = Renner has the most durable key bushing cloth. Any opinions on that? =20 What about lubrication on the cloth bushing material to minimize = friction and increase longevity? Microfine Teflon powder? But doesn't = that just sort of fall out quickly? What about some sort of graphite? A = synthetic grease, maybe like VJ lube? Anyone ever try anything like = that? Any other ideas (constructive)? =20 Maybe I should just stand in back of the piano player with a whip or a = well proportioned maple 2 x 4? =20 Thanks. =20 Terry Farrell ---------------------- multipart/mixed attachment A non-text attachment was scrubbed...
