Popular Mechanics published Forty Power Tools You Can Make in the early 1940’s as a thin hardback. The book is, as are most Popular Mechanics books, a collection of articles from the magazine. At a time when most machines were required for the war effort it must have been seen as a way to encourage people to keep up their hobbies in the face of scarcity.
The book is about 96 pages and has 3 plans for bandsaws, 3 for drill presses, 2 scroll saws (one of which is pedal powered!), 7 sanders of various types, 3 power saws, 2 wood lathes, shaper, power plane, model maker’s metal lathe, power hacksaw, and filing machine. Sprinkled within are other articles on accessories and other modifications to tools. It’s one of those books that can jog your creative urges as well as showing just how thrifty people used to be.
The book is available used from a variety of sellers between $2 and $10, while Amazon has a much higher price. It doesn’t seem to be available as a reprint.
