Topic tags/keywords: lathe turning refurbishing repair motor

I recently aquired a vintage sears craftsman wood lathe and was looking forward to getting started turning wood. One thing after another, I finally got it all set to run. Understand, I have no mechanical experience and I am self/youtube taught. When I run my lathe, after about 15 seconds, the Craftsman motor starts smoking and leaking oil from the top cover (picture below). What can I do to prevent this?

Sounds like a bad capacitor. Unplug the lathe take off the cover and remove the capacitor. Any motor repair shop should have a replacement

A polychlorinated biphenyl (PCB) is an organic chlorine compound … Some PCBs share a structural similarity and toxic mode of action with dioxins. .... Examples of closed applications include coolants and insulating fluids (transformer oil) for transformers and motor starter capacitors, also may be found used in old fluorescent lights.

It would appear that you are speaking some form of english; however, I am unfamiliar with this dialect.

Thank you guys for the “Dummies Guide” breakdown. I will try this and see what happens. Unfortunately, I don’t know of any machine shops nearby, so I’ll probably be ordering it online. Thanks again!

You don’t have to know any of the local shops to do business with them. Googling “electric motor repair shop Wichita, Kansas” will produce pages of listings. A few quick phone calls will put you in touch with someone who will be able to supply your needed part quickly and cheaply…

Good Luck!

PCB, is a cancer causer, wash your hands before licking them. Not a concern.

There are only one or two things that get the honor of a finger lick, and working on an electric motor wouldn’t be one of them…........ Jerry (in Tucson
