Modern Mechanix has a two-part series which they call “How to Kill Yourself Underwater,” comprised of most excellent scans of issues of the mag from 1933:
Exhibit A is “Build Your Own Diving Helmet”.
Exhibit 2 is “Build Your Own One-Man Submarine”.
I mean, Christ, I wouldn’t trust myself to put up shelving. And they want me to build a submersible?
