Chuck There might be a little dap of hardened glue inside the guide rail busing that is causing the rattle. I had that on a K&C grand, and it took me three service calls and about an hour of investigating before I?finally found the problem. Remove the damper, and using a drill bit the same diameter as the damper wire, clean out the hole.

I'm working on a Kimball baby grand with noisy damper felts. No noise upon depressing the damper pedal or any individual key, but a "rattling" or "buzzing" noise upon release in the monochord and bichord area. Trichords are all fine. Removing the action and manually lifting the damper heads produces the same noise. It's not a ringing damper--it's very abrupt--just a metallic "clunk" upon the damper's return.? I'd welcome any suggestions on how to further diagnose or cure these little beasts.? Thanks,? Chuck Raynor? Raynor Piano Service?
