They switched to charging $1 for the plans sometime between 1918 and 1920. The online magnet charger article is from a very interesting book.

I am looking for a plan that uses a 12 volt battery and I found a play by John Rex but that one sounds like overkill. Tim Your first decision is to identify the type of magnetos you want to re-charge, HT or LT. How wide will the magnet bars be. What will your power source be.
You can then design your charger to meet these criteria. If you want to use 12 volts and really zap a large magneto then the Rex size will be more appropriate than the Gingery. For LT magnetos the common view is that you will need to achieve 20,000 amp turns (turns of wire around the cores x amps drawn by the copper wire). Have a look at. I set out there the theory behind the charger I made.
