Stopped by the LHS to pick up a set of wheels yesterday-'pick up' wheels. The owner handed me a bag of metal wheel sets, many of which were quite worn. Quite a few were worn down to the point where they had a 'flange' remaining on the outside. I said to myself, 'Self' if you could turn these concave, they'e make great 'flanged' wheels for a wooden log (dowel) rail to run a little live steam tram and some disconnects on. So, the question is: can the wheels be pulled off the axle to chuck them in the lathe and turn them. I don't know how many different metals manufacturers use so not sure if this a 'yes or no' answerable kind of question. Opinions welcome! Bill
