Paul Clausing at work on his South Bend lathe, 1928.Įarly Years of the Clausing Manufacturing Company These were not in the same class as the South Bend lathes, being much lighter, smaller, and cheaper. It made small, cheap lathes that were sold through Sears as hobby lathes. Paul started looking, and he found a tiny business in Ottumwa, Iowa.

An Atlas just can't handle that.Email: t Machine Tool Archive Machine-tools for Sal e & Wanted On a heavy-duty lathe, you can use negative rake, which, for lack of a more technically correct description, pushes the chip off the workpiece. What material are you cutting and what kind of tool? You really need to use sharp tooling with positive rake so that it is mroe of a slicing action. You press the knurl against the work and at some point the flex in the bed won't let the tool press in any more (and you just are afraid to push it any more), I got a scissors knurl for that reason. The bed on my Atlas (1952) is so flexible that I cannot use a bump knurler. The thread wear might manifest itself in a wobble or concentricity issue, but I doubt it would cause chatter. It might have some effect during an interrupted cut, but I'm not sure chatter will be the result. The wear on the bull gear pin slot should have zero effect under continuous cutting, as it will be forced against the side the entire time. A 9" South Bend probably weighs MORE that your 12" Atlas. Seriously, compare your bed cross section to a 9" South Bend and you will see a huge difference. Your lathe chatters under heavy cuts because it's an Atlas.
