Lejay Manual - dynamos and batteries

Great bargain book of 50 “designs” showing uses for car dynamos and batteries. Make spot welders, electric fences, electric scooters, bench drills, wind generators etc. Whilst the electrical parts of the design are specific, the rest is conceptual, and you will have to use your imagination. Useful and fun! 45 pages.

In the 1930's the LeJay Mfg Co in Minneapolis began publishing a booklet describing unusual electrical projects. As new editions came out, new plans were added until by 1945 there were 50 separate "chapters".

Most of the articles in this edition deal with the conversion with now-antique auto generators into 110 volt alternators, other voltage generators and motors. A lot of this info was used in areas of the country that hadn't been electrified. You could buy old generators from auto junk yards, build a windmill, repair old auto batteries, and use the electricity to run homebuilt motors, welders and so on.

Please note the picture shows a different cover to the latest printing.
