List, I am working on a twenty year old Baldwin R which has not been played much. The front rail key bushings were in various stages of too tight. The key pins are .145", so I initially eased with a .147" straight broach in a rheostat controlled soldering iron (set to a setting used successfully on many previous outings). Barely made any difference at all. Stepped it up to the next larger size broach, .150". Things improved but just barely. I was not getting the slight but positive "knock" from side to side that I usually work for, but the keys were at least coming back up (!). I don't know if the bushing cloth is too thick, or too spongy, or if the mortise was somehow too small to begin with (if that is even a possibility), but I do not have great hopes for the keys remaining functional for long as some are already showing signs of needing to be eased again. So my question is this: Has anyone used V S Profelt with appropriately sized cauls overnight as an effective fix for bushings that are too tight?
