themayor,
I am surprised that your question brought out all of the cheerleaders for the various brands of lathe. As I read your original question, you did not ask for a purchase recommendation, nor do I think you are in the position to appreciate all of the nuances and deeper philosophical qualities regarding the choice of one brand of lathe over another. You asked, in so many words, "How hard is it to run a lathe?" If you have the right teacher, and a modicum of mechanical inclination, it's not hard to do at all. By the same token, doing good work, to close tolerances, is NOT, by any stretch, easy for the novice. They don't pay experienced machinists the "big bucks" just because they're grouchy and they smell funny (it's the o'd Dykem that gives them the smell).
What I would suggest, MOST strongly, is that you find yourself a good trade school (or vocational tech school, or whatever you folks may call it in your corner of the world) that will provide night school classes. I would argue that learning to run a lathe (or any piece of machinery) is best learned from someone who has done it. I have never read any book which could give me an appreciation for the "feel" of a light cut or what "chatter" feels like. Also note that lathes are precision machines that can be easily damaged (ask any apprentice who has dropped a four-jaw chuck on the ways), and they are VERY expensive to repair. If operated by the ill-informed or ignorant, they can also be VERY dangerous. I won't bore you with "Signal-40 esq" tails of what I saw while I worked at Mack Trucks... but suffice it to say, being wrapped around a 14' walking-beam axle, which happened to be mounted between centers on a 24" LeBlond engine lathe at the time, can be embarrassing, not to mention painful. Save yourself a bunch of money, and maybe even some skin, and go to school.
Oh... and for those who care about such things, I ran a 17" South Bend Turnado gear-head engine lathe for many hours while I was at Mack. Among all the other great lathes they had back then (when they "built" trucks, not just "assembled" trucks), which included LeBlond, Monarch, and quite a few others, I always thought that the Turnado did the best quality work, with less effort, than any of the the others (the Monarch was a close second). South Bend lathes have much to recommend them. By the same token, I never ran a Jet, Grizzly, Logan, or Atlas lathe that impressed me at all. Good lathes are heavy (for their size) and carefully assembled. You will never be able to do close-tolerance work with a lathe that is built loose and flimsy. Just ask your teacher what he ran. If he is knowledgeable, and honest, he will be willing to give his students good advice. I never got any bad advice from the machinist I was apprenticed to (not regarding machine work, at any rate). His words were few and his praise almost nonexistent, but what he did say was always worth remembering.
