There were still a couple left but the bearings are gone. Except for the bearings everything else looks OK.
I have no speed control so it's going to be scary testing this thing. It's either 50,000 rpm or off. Should be fun.

Ahh, that makes more sense. As long as you can make out the bearing numbers it should be easy to get direct replacements. Even just being able to measure them will get you close. I usually recommend tractor repair shops for sourcing bearings locally if you have any available in your area. Living in the grass seed capital of the world, I have an abundance of them.
