---------------------- multipart/alternative attachment Ron & All After following up on many of our high use rebuilds I am extremely disappointed at the extreme wear factor on all the bushing cloths we've tried. It's primarily the front rail pins. In one church, 2 years of med heavy playing & many glissandos later the bushings are gone & keys as sloopy as before SO when I get done with this post I'm ordering the Kangaroo stuff from Schaff. I see no other alternative. I'm currently reworking a 1958 7 ft Petrof. Nice piano. The center rail bushings are in perfect tolerance. The fronts were felt & we changed those due to exessive slop. There may be a chance of corrosion on brass but right now I'd take my chances with the leather even on the brass pins. Hey if they last more than 2 years under heavy use then I'm even, if longer then I'm in the black. Dale Erwin 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. ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
