WIDE THREADING RANGE Atlas 6-inch lathes are equipped with change gears and thread ing dial for cutting all threads from 8 to 95 per inch, right or left band, in the following standards: National Coarse (U5S), National Fine (SAE), Acme, Square, and Whitworth. This is a reproduction, not a photocopy, of an Atlas 6″ Lathe NO. 618 Instructions and Parts. This lathe was also sold under the Craftsman brand name. This manual contains information on setup, lubrication, maintenance, and controls as well as a complete parts list and exploded views and adjustments.
At the end of May, 2011, I purchased my first (and only) lathe.I had been learning how to use my mill and was eager totry my hand at other machining endeavors, and began shoppingfor a lathe. One good source advised me to buy a used Southbend(and I still consider this excellent advice). Another trustedsource said that I would be quite happy with any of the smallTaiwanese lathes being sold by ENCO and others.But I caught wind of a used machine for sale,made an offer that was accepted for the lathe(I got the lathe with 3 and 4 jaw chuck and a lot of tooling for $500)and am now busy sorting out what I have.What I have is a Craftsman Model 101-07403 lathe that wasmade by the Atlas Lathe Company.This is a 12x36 inch lathe, meaning that the 'swing' is 6 inchesallowing 12 inch diameter objects to be turned, and the bed is 36 inches long.According to dates scribed on the races, it was manufactured in 1951.My lathe is serial number 32068 (the number is stamped on the topsurface of the ways, right above the right lead screw bearing and support.Just for the record, the date stamped on my left spindle raceis 8-14-51, and the date on the right spindle race is 5-10-51.
I was warned about several things even before I bought it.First, I was told that this Atlas lathe was among perhapsthe worst lathes I should even consider buying.Second was that the gears and many other parts were made out of azinc-aluminum alloy called 'zamak'.I was also told by the same fellow that told me all of theseworrisome things that he once made a living as aprofessional gunsmith using one of these lathes.Also, I considered that the lathe I was looking at is at least 50 years oldand still running; so those Zamak gears, though not what one would wish for,were still quite serviceable, and if I treated them gently, would likelyserve me just fine if I didn't abuse the lathe.
The zamak parts on this lathe receive a lot of abuse, and perhapsrightly so. On the other hand, the use of zamak serves two purposes.It makes the lathe lighter -- no small thing if you have to move a largelathe. They also make the lathe affordable, certainly at the time ofmanufacture, and still today. The gears were die cast out of zamakrather than being machined from steel, saving weight and expense.
Craftsman of course doesn't actually make anything, but is just the nameSears slaps on whatever products they arrange to carry in their stores.Atlas bought Clausing in 1950, and around 1969 renamed itself Clausing International.Amazingly Clausing still stocks and sells partsfor the Atlas Lathes at theirService Center in Goshen, Indiana.Call them at 1-800-323-0972 or email at info@clausingsc.com(I called them at 1-800-535-6553 on 11-17-2011, so the above phone numbermay be out of date.)
The Spindle bearings can be either Babbit metal (in which case the headstockhas bolts with clamps that hold the bearings), or roller bearings (in which casethe headstock is a single piece, no clamping bolts. Mine has roller bearings.Mine also has the 'quick change gearbox', which is apparently an option, but whichshould be a great help cutting threads.

- Atlas service bulletins (valuable)
- Here is a nice discussion of lathe terminology.

- Speeds that can be set up with the Atlas.
- Alan's speed tables.
There exists a comprehensive 240+ page owners manual for the 12 inch Atlas lathethat includes maintenance and lubrication instructions, 'probably the best instructionbook ever produced by a lathe manufacturer.' There is also a 61 page 'supplementary'screwcutting instruction book as well as other documentation. I have had theinstruction manual waved under my nose, but still am eager to get my own copy.
