I know there is information all over the place, but how much of it is the same thing, explained in a different way? I mainly want to know if I could get started for under $500, because if I decide later that I don't want to invest further time, I won't be set into financial ruin. I'm thinking of starting just as a hobby, something to take up time. I'm assuming I'll need a lathe, and drill press, as well as some briar blocks and pipe stems. How much would all of this cost, and what else would I need?
