Re: smithy AT-300 LATHE/MILL
Just relaying one not so cheap lesson I learned. Combo lathe/mills usually do a poor job at both turning and milling. I am not saying you could not do gun work with that particular machine as I have no experiance with it, but doubt that it as rigid as I would like. That said I have seen some great work done on some smaller machines, my limited skills apparently take bigger machines.
I admit that I know just enough to be dangerous.....but dangerous at ever extending distances.
