I'll have to take apart the die grinder I have to see what materials are in it. I'll post pics when I do.
You are correct though, most grinder's rpm is way higher than what an alternator will handle. I suspect once you put the loaded alternator on the grinder you'll drop those rpms to a reasonable level though. Hopefully no reduction is needed. To be honest, I'm more worried about getting enough pressure to keep up with the grinder at this point.
