Dear Colleagues, Am regretting not replacing damper guiderail bushings on a recent Steinway (1976 B) parts retrofit. The new damper action installed smoothly and required only minimal re-bending of damper wires. However, in spite of careful attention to proper alignment and seating of bichord and trichord damper wedges, I can't seem to eradicate an 'oink' together with longer-than-satisfactory 'ringing-on' of most dampers in this part of the scale. There is actually quite a bit of free play in the guiderail bushings ... you can see the damper head wobble when the key is struck. Am kicking myself for neglecting this important interface but, short of rebushing the rails, has anyone had success with moistening the bushings in hopes of swelling them back to acceptable tolerance? I sometimes do that with moderately compressed keybushings ... would it work on these as well? If so, would you mind sharing the procedure? Thanks and best regards from the Canadian prairie!
