Well, tonight I tried the die grinder again using the flywheel method using the alternator itself as the flywheel. I spun it up and then connected the alternator field wire. It very quickly reduced in rpm and choked the grinder. It probably produced usable voltage for 1.5 seconds. So, you'd need a fairly hefty flywheel I'd imagine.
