Ok, I'll give it a whirl.
I haven't yet taken the mechanism apart, so precise measurements of the pivots isn't yet possible. The plates on my clock are 2.5mm thick; no bushings in the Timesavers catalog seems to be 2.5mm deep (2mm or 3mm, but no 2.5mm). Am I missing something, or do I have to choose too thick or too thin? The two bushings that clearly need to be redone both have pivots close to 2.5mm in diameter. Should I just buy a good variety pack of bushings, making sure that it included some of the larger ones like these? I have a house full of old clocks that periodically need fixing, so having a supply of bushings doesn't seem like a bad thing.
I gather that, by turning the winding arbor in the direction the spring pushes it, I see where the force on the pivot is wearing away at the plate; is this correct? Then I'll want to ream out the hole, keeping it centered properly, until it's round, and wide enough to engulf the off-center wear. Is this correct?
Is it ok to bang the bushings in with a hammer/anvil, or do I need some kind of fancy tool for the purpose?
Thanks much for your help!
