I tried the way Mark and Joe described. Actually, I had a student switch it. About the time it clicked on and started making voltage, the positive battery charger cable came into contact with the case of the machine. Which of course caused sparks and the handle plastic to catch on fire. I had students running all over the room thinking it was going to blow up or something. It amazes me how scared some people are of a little fire or a few sparks.

I bolted it up to the Gasser tonight and it won't work. The Gasser has really big V belts compared to the M715 version of V belts. I tried swapping pulleys, but the shaft of the alternator is huge compared to the generator shaft. I was taking a break from paint prep on the M715, so I just put the generator back on so I could still drive it around over the weekend. I might chuck the generator pulley up in the lathe and try to cut bigger groves. Which means I am going to have to figure out all those gears for the feed speed on my lathe. It won't be the next few days.
