Fred: I have one customer with an SD-10 as you describe. It too is an older unit and those pieces are not individual pieces but 1 per section. Several years ago I did tighten the Allen screws that are underneath because it seemed to have some strange noises though not as bad nor as sudden as the ones you describe. This piano (it belongs to one of our piano faculty) needs rebuilding. I have wondered about those parts as I'm sure Baldwin no longer has them available. I think if I were faced with your colleague's problem I'd just string braid off those sections. I have done it to an SF-10 that was in a recording studio. They were close mikeing it and complaining about the odd noises. When I braided those sections I was an instant hero. I'm sure that fix goes against the manufacturers intent, but whatever they intended, it sounds bad. dave *********** REPLY SEPARATOR *********** On 6/12/2003 at 9:37 AM Fred Sturm wrote: >A colleague of mine (not subscribed to the list) has a problem with a >Baldwin concert grand in his care.
