I fully concur with Jim (infra), by the way...the only real fix for these parts is to throw them away and start over...anything else is an exercise in futility and wasted time. Best. Horace <blockquote type=cite class=cite cite><blockquote type=cite class=cite cite>I prefer new parts whenever feasible.  However, there are those times in an old piano when rebushing might be the appropriate thing to do.  Perhaps rebushing is also temporary, as Bob Davis said, but if it's still OK after 25 years, and mine have been, I don't call that "temporary".  If a flange is saturated with tallow, or some other goop that someone has soaked it with in trying to lubricate it, you can bet your boots I'm not even going to try to rebush it.
