CLAUSING 100 – Atlas 4800 Series 12″ Metal Lathe Operating & Parts Manual

This is a reproduction, not a photocopy, of an original Atlas 4800 series and a Clausing 100 Mk. 3a 12 Inch Lathe Manual. This manual contains information on setup, lubrication, maintenance, and controls as well as a complete parts list and exploded views and adjustments

This particular lathe manual can become confusing to many people, because the model number was changed a couple of times during production of the same lathe. The reason for the changes comes from the fact that Atlas bought Clausing in 1950 and changed the Clausing 100 Series to and to an Atlas branded 4800 series. Lots of customers of the Clausing 100’s didn’t want their lathes branded Atlas, and it confused them when they asked for service. So after a few months Atlas re-branded them Atlas/Clausing 100 series lathes until they stopped producing them in 1965. This manual also includes the Atlas/Clausing 111

One other thing is that Clausing made significant changes to the 100 series during it’s production run. Below is the gear box and headstock covered in this manual. If you have the V shaped gearbox, this manual should cover your lathe. The gearbox looked significantly different, if it was there at all, on older models.

I have collected this information for many years and have found the information they contain to be priceless in using and setting up the machines properly. I believe this manual will be a valuable resource of knowledge that will provide a lot of helpful information that is often hard to find. My manuals are not photocopies. I maintain a high standard of quality in my reproductions. Most of the manuals I reproduce look better than their originals. I have professionally digitally edited every page,and removed stains, wrinkles and handwriting. All of the manuals are printed on thick white paper to withstand shop wear and tear; they are then comb bound with heavy cover pages so they lie flat on the workbench.
