[QUOTE="4ked Horn, post: 71068, member: 11"] You are getting a ton of good info here and I am learning a bit as well. I just wanted to chime in with the little I know. As I was leaving the college machining program we received 3 cheap japaneese lathes and I wouldnt give you a buck for any of them. They would NOT turn a diameter without leaving a nasty chatter pattern regardless of the speed or feed or depth of cut or tool point shape. They were worthless except for roughing out a part while waiting to get on another machine. Most of the class was taught on old southbend belt driven lathes. They were short on power but long on accuracy. In fact most of the machines (lathes and mills) were WW2 vintage and built like the tanks they were producing with them. My favorite lathe to use that was gun shop sized was a Sharp 16x48 (or close) gap bed. It was one of the lathes at my first machining job. I thought that if I ever got a lathe for tinkering at the house it would be the same thing but with a 60" bed if they even made one. The lathe had enough mass to be chatter free and I have turned very bright and smooth finishes with it using carbide bits and 4140 steel. The speed range went up to 2k RPM and the spindle was around 1.25" or 1.5". I don't know how well it would work as a gunsmith lathe but it was a dandy for making money at +/- .001" tolerances.
