I picked up an abused Boice Crane 3700 variable speed lathe at a estate sale recently. After a couple of weeks stripping it down completely, removing surface rust and having the bed repaired, I am about to turn what was a piece of junk into a beautiful, vista “machine green” woodworking tool. I now have one new problem (that I may have caused?) I shorted out the motor when I was setting up the spcket light, the socket wires may have crossed and sparks flew and the circuit shorted out as well. I repaired the cross wires, flipped the panel switch back on and now the motor shorts out in forward but not reverse? I know next to nothing about electricity so am wondering what is going on now and if I damaged something in the short episode while setting the machine socket lamp up?
help.

Congrats on the lathe. All I can tell you for sure is you have a short somewhere in the forward circuit. Chances are you didn’t hurt the motor because it still runs in reverse. The problem is most likely in the switch or the junction box(es).
It might be worth your while to check in at OWWM.org and VintageMachinery.org as well. VM might have a copy of the owner’s manual and other info on your lathe, Your lathe qualifies as OWWM and there are some very knowledgeable people there too that might be abe to help.

I am feeling a little better now. Thanks for replies. I am getting ready to unveil soon. I will post some pictures here. I have someone coming over to wire up my new Mini Max 16. I will have him take a look at it. No doubt I messed with something I should not have somewhere. My mother used to say, “a little knowledge is a dangerous thing”. She was right most of the time.

BTW—I have looked at that site. And…....I did find the manual there in PDF form I was unable to download. Sort of has given me the bug to find and restore other machines. It’s addictive!

Shorting out the light socket would not have harmed the motor… I’d look more at the switch that may have shorted across the contacts. Grab a multimeter and start doing some testing.

Also… I restored a 1954 Boice Crane jointer a while back. Originally it was either black or a very, very dark grey. I wound up painting it green as well (although I went with hunter green).

Cheers,
Brad
