Drum switch wiring 120 volt

[Ktencza]

I have a furnas r44 drum switch for my jet lathe with a dayton single phase motor, I want to wire for 120 volt cannot figure this out for reverse working also can some one help. Enclosed are pictures of switch and back of motor, still have the 3 phase wire ill be using colors are green, red, white, black.

You're in luck- you have the best drum switch for use with a Dayton motor
I'll post a sketch for you shortly

This should do it: configure the motor for 115 then make the changes shown: (brown and white wires as per motor diagram for 115)
Extend the red, black, 2 and 5 to reach the drum switch-using 1/4" lugs +heatshrink tubing makes for a clean install
Don't forget safety ground wire to motor case and switch enclosure both (not shown)
12 gauge stranded wire should be fine- any thicker will be hard to stuff into switch box- 14 gauge wire is fine for motor red, black, 2 and 5
Swap red and black if required for rotation vs. switch handle

Thank you brother just got the lathe all cleaned and gone through need that reverse working lol.

Am I still configuring the red and black in motor for 120v or just extending straight to switch, thank you again much.

You extend the red and black straight to the switch- that requires adding to the length with extra wire and either soldering or slip-on lugs
The red, black, 2 and 5 wires are low current starting wires so can be thinner like 14 or even 16 gauge wire
The ones to motor terminals 1 and 4 should be heavier like 12 gauge wire

Thank makes better sense now. I'll post when I get it running.

It's alive thank you very much. It was harry putting all those wires in that switch but worked well and is clean ill post pictures little later. Much appreciated.

Yeah they don't give you much room in there-using thinner wires where you can makes it a bit easier-
Glad to hear you got it going

I have a similar question, but different in the specifics enough that I could use a little help.

I have a Leland Faraday 1/2 horse, with the motor leads being 2,4,5 (wired together right now) and 3,8 (wired together) with a blue wire. I need to hook this up to a Square D drum switch. All wires are black and numbered, except the blue wire. I currently is set up to run on 115VAC. This is the motor that came with the lathe, and while I didn't wire it up, I did check to make sure it works. Obviously, the ground needs attaching.



This has been my hold up to going forward with my SB9, and when I can get it off my bench I can move on to the carriage.

Thanks in advance!

I bit of poking around the internet, and I found this:

It took a bit to decipher it, but it seems like it should work (I would have drawn it a bit different, for clarity.)
