well if you decide to venture over to the practical machinist board you will find why alot of guys are going out of business. you can't really make a whole lot of money selling hobby stuff. everyone wants something cheap but really reall good. as for actually being a machine shop, no bank in their right mind will give you a loan for it and really anyone else unless they really are itching for a very difficult way to make money would stay away from it. building and land are cheap now, and old antique machinery is liability, you'll spend more time fixing it than running your business.
