AFAIK he doesn't run the machines himself. I am assuming he is going to hire a machinist/smith that has built guns before.
Sorry I am a little light on details of what exactly he is doing. I haven't talked to him for a few months and he called me with a domain name question and I asked what was new and he said he was going to start manufacturing 1911s.
I plan on going over to his shop when it is setup to get a better idea.
