---------------------- multipart/alternative attachment There is a Mason & Hamlin upright model 50 (vintage 1975) I service and at the last tuning the owner was complaining about bobbling hammers. The hammer pinning is very loose. I played around with the note that was bothering her the most and through a combination of repinning and strengthening the hammer return spring was able to all but eliminate the problem. The piano is in good regulation. Here's the issue: The action is really poorly made. 1975 was not exactly the golden age for these. In repinning the one I did, I could see that the flange bushing cloth was poor quality. It would be wonderful to replace the whole action, but that's not going to happen. Does anyone know if it's possible to get replacement hammer flanges? These flanges are different from the generic ones sold by piano supply houses. If that's not possible, I have to go with rebushing what's there. Any recommendations on a good source of flange bushing cloth? I know M&H are making these again. Anyone know if the action design is the same? thanks, Aaron ------------------------------------------ Aaron Bousel Registered Piano Technician, Piano Technicians Guild abousel@comcast.net (413) 253-3846 (voice & fax) ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
