Indeed, that is what I would like to do, but as I stated in my original =
post, "I don't see that the supply houses offer plated/steel pins in the =
Yamaha size." 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?

  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.

    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.

    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.

    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?

    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)?

    Maybe I should just stand in back of the piano player with a whip or =
a well proportioned maple 2 x 4?

    Thanks.
