I'm sure there's videos of how something like that's done, but it's still got to be a major project. Sadly for me, all the great deals on those older machines are all up north. Georgia was never a hot bed of industry like Ohio, Michigan, etc. Trying to find used lathes and mills down here is a lot more difficult. I also missed a killer deal on a loaded Emco Maximat Super 11. I was going to buy it, then a friend had an emergency, and by the time I got back it had already sold.
