I would like to salvage some HO track from a layout I am dismantling. I plan to remove the feeder lines from the sides of the track. Any suggestions how to clean on the solder from the sides of the track?
It definitely works. Also called Solder Wick; any Radio Shack or electronics supply store will have it. I find it works best if you immobilize the part you are working on, place the braid's end against the solder, and your soldering iron against the braid. As it fills with solder, inch feed a new area of braid into the battle. It gets hot, so leave adequate space between the work and the fingertips.
I often leave it and just reuse the same section in a different area were leads will be attached. I buy used flex track at my LHS for about $1 for a 2 - 3 foot section. At that price I cannot be picky.
