I would think starting a job shop with a "hobby " machine would be great.Ive had many offers to do lots of stuff in small batches and large batches for defence contractors that cant get their machine shop to make small batches for a small project that needs to be done now. if I had a cnc mill I would do them and probably be quite bussy and make lots of $$$ .but at this point in my life....I want to do stuff for ME. Ive done everything for everybody all my life.and my stuff always got put off...almost 30 years ago i sold my money making race car to build a new one....( drag racing) last year I sold off all my unfinished racecar stuff including the unfinished new professional built racecar. 85% of it was new unused. I got about 15 cents on the dollar for it all. ( I got $15000 usd) it was all high dollar parts. thus the reason Im done working for any body else. so you there should be lots of work out there for you if you get word around and do good work. Good luck in you new venture!!!
