In the 1940s and 1950s, home metalworking enjoyed much greater popularity than it does today. The Atlas Press Co. of Kalamazoo, Michigan was the largest supplier of machine tools to the hobbyist market, sold under both the Atlas and Craftsman (Sears, Roebuck & Co.) labels. Sears was a major outlet for Atlas, and resulted in many machines being sold to the farm market. The war years also saw these machines at work in industry, doing smaller jobs and freeing larger, more capable machines for other tasks.
The popular magazines of the day reflected this market and interest.
Presumably, Atlas placed machines with the leading magazines, much as Delta
does today with woodworking machines on programs such as Norm Abrams' "New
Yankee Workshop." Staff or freelance writers such as Sam Brown and H.J.Chamberland
produced metalworking articles on a frequent basis for the "screwdriver
books" of the time, most notably Popular Mechanics and to a lesser
extent Popular Science. Following is a listing of articles of interest
to Atlas mill and shaper owners. Many of these are concise, well-illustrated
tutorials on machine operations, as good or better than any I've found
in more conventional textbooks.

Atlas mills were sold by Sears under at least one part number: 101.15500
The Sears online parts catalog gives part breakdowns of these mills by Sears part number, but although listed, most if not all of the specialized parts are no longer available through Sears. What few parts are available are standard off-the-shelf hardware and components, more easily and cheaply found elsewhere. To enter the Sears parts listings, click on Sears online parts catalog and remember to enter the number 101.15500
Atlas Press Co. has a web site, including corporate history. Any owners of these machines should at the very least have the official factory user manuals and parts lists; they're affordable, I think about $5, and will tell you things you didn't know -- or know you needed to know.
The Atlas Press Co. web site has only one item of information pertaining to the milling machines: a service bulletin detailing how to replace the spindle belt. . There is no Atlas web information on the shapers.

Here is a more complete corporate history of the Atlas Press Co ., courtesy of Richard Stines in San Diego.
There is an e-groups online mail list ;"This group is dedicated to the users of Atlas metalworking machinery including lathes produced for Sears by Atlas and AA Engineering under the Craftsman name."
Tony Griffiths in England has been compiling thumbnail sketches of various
machine tools. Those most likely to interest American users are:
Ammco/Delta Rockwell shapers
South Bend shapers
Next in priority after the official factory owner's manuals, Lindsay Books has some excellent, affordable publications of interest to owners of both mills and shapers. My personal recommendations include:
Shaper Operations: Lessons in Using a Shaper by J.W. Barritt
Shapers by Emanuele Stieri
Production Shaping by Machinery's Industrial Secrets
MILLING MACHINE BOOKS
Milling Machine Operations by J. W. Barritt
Milling Machine Practice by the Cincinnati Milling Machine Co.
Not sold by Lindsay but worth digging out of the used bookstores:
Practical Treatise on Milling and Milling Machines by the Brown & Sharpe Mfg. Co.
Available from bookstores, MSC Industrial Supply, J&L Industrial Supply, and the usual suspects:
Machine Shop Practice by K.H. Moltrecht. 2 volumes, about $20 per volume. Shapers and mills are both covered in Vol. 2.
Another one to be dredged out of used bookstores is the U.S. Army Machine Tool Field Manual. There is an online version of the U.S. Army machine tool manual but it no longer covers shapers. The print version (at least, my 1973 edition) does cover shapers and mills in good detail.
