I bought a 40W = soldering iron at Big Lots for $1.99, trimmed the bevel off the tip and = swaged (squeezed/pounded) a # 7 bridge pin into the end. Used in = conjunction with a temperature control (I like the one Pianotek sells) = you can iron size the bushings either in or out of the piano. I then = give them a squirt of TFL-50 dry lube. BTW, I've been using the TFL-50 = for emergency easing of damper bushings without removing the action = also. You can use the little tiny spray tube that comes with it to get = down between the dampers and spray the wire (while raised) and the = bushing at the same time. I don't know if it chases moisture out and = lubes or whether it just slicks it up enough, but it sure works = great.

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).
