Check out these basic machine shop videos put out my MIT. They are from about 1995 but are great introduction videos to anyone learning to work with metal. So far I've watched 8, 9, and 10 which are an introduction to using a metal lathe and now I'm starting from the beginning. They are about 30-45 minutes each and move along pretty slow but are worth checking out.
