Sizing Guide Rail Bushings

[Fred Sturm]

Avery,
	I saw Brian DeTar demonstrate using a heated wire, chucked in a
soldering iron, similar to the setup Pianotek sells for key easing with
heat (with temp control). Looked like a great idea, though I've never
got around to making one. If I did, I think I'd just take a piece of
round brass stock the right size to fit in the tip, drill a hole in the
end, and hammer in the appropriate size pin (friction fit). I haven't
rebushed a rail in a while, so haven't bothered to do it yet.
	How do you know it's right? One way is to take a straight wire and run
it through each bushing. If it drops easily of its own weight, you're in
good shape (assuming it isn't too sloppy).
