Well, I've managed to do some work!
I'm currently working on a boat powered by a tiny Philcraft steam engine....for this I wanted to make a very light prop shaft....I've used 1/8" brass round running in a copper tube. To minimise friction, I've skimmed off a couple of .01" of the portion that runs inside the tube. as the shaft is about 3" long I couldn't just chuck it, and as I don't have a fixed steady I held the loose end of the shaft supported in the drill chuck on my tail stock, with lots of oil to prevent friction....everything went OK, I only took 3 tiny little cuts, and the drill chuck didn't get hot.
I always think "if it worked, I must've done something right", but is this the right way to go about these things?
Below's a picture of my kit.
