Hi Alan. In this exact instance I cant say really... but graphite has been sited by many to cause similar symptoms. And the reasoning behind the charges seem sound. I think that graphite in bushings is not a good idea in any case.... especially since there seems to be a much better alternative... namely teflon. I have run into one instrument where the treatment I outlined did not stay very stable over a long period and I had to go back and redo some of the re-pinning. That was a very old Bechstein that had quite crusty bushings. The lady didnt have any money really... certainly not enough to replace parts and hardly enough to pay me either. So there has been some pro-bono work there :) Otherwise... on newer instruments that I have reasonable grounds to believe that graphite is the primary foreign agent in use.... this works great. Cheers RicB Hi Ric, So you think the graphite is the culprit?? Is the graphite only on the surface of the cloth, such that once you treat as per your post, they stay stable? thanks, Alan E.
