I don't know yet. I work full time at a college on the coast. And have a family to support. And i'm mostly interested in building custom rifles. But I know you got to learn the basics first. I have access to CNC machines & LATHES here at the college. And i'm enrolling in the machinist courses this summer. I got to find out what I can and can't work on at the campus. as far as weapon parts go. Don't need to get into any legal problems. :NO: There is a school in arizona that is 2 weeks long that goes over basic trouble shooting and repair, case harding, bluing and stock bedding. I know you don't become a gunsmith in 2 weeks but it will give me a hands on start in the right direction. And I can work my vacations around class dates. So I can go 3 times a year. And every class is more advanced.
