I've been woodworking for about 4 years now, building mostly shop fixtures and jigs , and I'd like to eventually get into turning pens, bowls (small and large), and vases. Will a single lathe do all of these? I'm just dreaming now, but eventually I might be able to spend $500 or so on a lathe, maybe a used one. What features should I be looking for? What books or online articles are recommended?
