I was up to my in-laws for Thanksgiving. My father in law has a vintage Delta Milwaukee drill press that we just pulled out of storage in his barn and put into his newly built shop. When put into storage, the motor worked.
Cutting to the chase, I replaced mouse chewed fabric covered wiring in the motor and the line cord. The motor runs if you give it a healthy spin by hand and the bearings are shot. Clearly the cap is no good - especially since it was crushed! Unfortunately, the cap's markings are not readable. So, I have no idea what capacitance we need to get this motor working again.
I took the motor home with me for new bearings and a cap.
It's a 1/2 hp 115/230V motor wired for 115V. At work, I have a box full of new and used motor caps, so chances are I'll have something that'll work. My best guess based on what markings are left is 16 microfarads, but my level of certainty is only about 30% (could be 160 uF for all I know). Can anyone give me an idea what cap value to start with to get this thing running?
Thanks!
