Forming Methods Vol 2 - circa 1943

£8.10

More forbidden fruit from the Navy Department, Bureau of Aeronautics! This volume again comprises two booklets, the first being Forming by Draw Bench, Power Rolls and Spinning. The first two of these processes, involving the use of dies, or special contouring rolls, are very much industrial, but spinning is a hand process, and is well dealt with here, albeit in only nine pages. The second booklet is Heat Treatment of Aluminium Alloys, a subject I haven’t comes across before, and whilst it is described here as an industrial process, I think the home engineer might be able to do this on a small scale, if he feels so inclined. 84 well illustrated pages. Softcover.
