Teejk and Tennessee, thanks for your input. I’ll definitely take a look at the outlets and make sure the wiring is good and tight. I already checked all of the connections in the panel, and the screws were all tight.

I actually tested out the lathe and DC independently, in 2 different outlets. The lathe would run, but was slow, and the DC would try to turn for a few seconds and then the breaker would pop. The capacitor in the lathe smelled really bad of burned electronics, so I ordered a couple of those to pick up this afternoon. It turns out the cap on the DC is the same, so maybe I’ll get lucky.

I happen to have a fancy surge protector that I use with my home theater stuff with a digital voltage readout. While plugged in and no load, it read 120v exactly. When the lathe was on it dropped to 110v, and when the DC was flipped on the voltage dropped to below 80 before the breaker blew, like Tennessee described.
