Tools: Do many of you all prep hand tools? Drills, grinders and the like that will run without electricity? It seems to be my specialty among the people I know. I aim to fix for trade.

Finished my 2x72 belt grinder kit using parts from broken treadmill (More info in comments)
Finally got most of the remaining parts together and did a little live test.

The slowest speed is about 800 SFPM and the fastest is 5100 SFPM. I have not tested it out under load yet, but It should have ample power for my needs.
I was looking at the AC control VFD motors and drives they seem relatively expensive. I had salvaged the motor and power supply from a 21yr old treadmill. It is a 1.5hp permanent DC magnet type rated at 5700 rpm. The speed controller has some sort of slow start circuitry built in. It’s already wired for a safety stop as most treadmills have some sort of key pull. The motor is also has a thermal shutoff.
I’ve added the enclosure, switch box and work table, but still need to build a stand.
What is interesting that I’ve seen tons of old working treadmills at yard sales and on Craig’s list for $200 or less and even $25. Those motors and drive circuits can be very useful for DIY projects. I’m wondering if anyone else has done this.
