Sposed to go get this monster tomorrow morning!

South bend 10ft lathe. 15in swing. Was under power and working when I bought it. I do not have 3 phase in my garage so I can not demonstrate. Was originally used mostly to bore cylinder sleeves in Caterpillar engines for a local gravel pit. Has been in my garage since I purchased it. Is very heavy and approximately 12ft total in length. Comes with everything I got with it. Too many irons in the fire is my reason for selling. Price is 500 obo. Feel free to message me with any questions or if you want to come take a look at it.

couldnt resist, so hope its a decent one. a few pix from his ad. --- I will have to figure out how to put a single phase motor on it. We had 3-phase at the other place, but only 1-phase here.
It comes with some odds and ends too, so we see!

even as much of a relic as it is, for 500bux you stole it Sonny..it's all there..check out a VFD for the motor drive,you can get them single phase 220v input and 3ph output for about 200bux off ebay,cheaper than a single phase motor and it gives you variable speed as a benefit..FWIW

Got a big motor ( i think 5 hp) on a sheller I bought, sheller motor has a tad bit bigger shaft than the lathe motor. Dont know if I could turn down the shaft or not. Run motor and hold grinder to it,----- done that before and got buy with it!
Then I could use the funky original chain drive sprocket on it. Cant ream the sprocket cause there is not enough meat there to be removing any!

looking at the motor tag in your picture Sonny it says 220v, 3.2A, 3PH which comes out to be 1HP.. I've used a VFD to drive small 3phase motors off 220V single phase(two hots)..the small box VFDs are easy to use and set up, simply give it 220V two wires and it gives you three phase power out to run a motor but also gives you adjustable variable speed..great for a lathe

The motor is do old I was afraid to try anything on it. Seller said he heard it run when he bought it before they un-hooked it to load it on his trailer.

something else you can look into is a 'phase shifter'-its a small plastic box the size of a can of beans that runs a 3-phase motor up to 5hp on single phase..like $120bucks, pretty economical FWIW

search on Amazon- MY-PS-5-N-1

got the $99. one ordered, sounds like the right one for my 1 hp motor. You will have to help me wire it up when it comes. I will take pix of everything to give you a better idea of what we have!

sure Sonny its pretty simple..1st off be sure you have a good 220/240V circuit into your barn or shop area..two wires into the shifter and three wires out to the motor. I would strongly suggest a disconnect switch or plug to isolate power from the shifter when not using it..no sense having 220V sitting there applied to the shifter if it doesnt need to be..plus NEC also states you to have a disconnect; a plug will do

The 220 in the shed runs my big air compressor and the welders. Its a 50 amp 220 breaker.
I only plug in the machine I am going to use and otherwise everything is unplugged from the recep. at the box.
Also I only plug in/run 1 at a time so as to not overload the 220 circuit since its only me runnin the stuff.

something simple like a drill or table saw youre OK with leaving plugged in, but anything with electronics,like speed controls or computer control crap on it leave it unplugged when not using it so surges and voltage spikes won't destroy it..we had a concrete forms truck hit a power pole here out on the road and the pole top broke off with lines at 33,000v dropped down onto the 13,000v below that feeds our road and fried a lot of stuff up and down the road..took out two pole mount transformers,three surge suppressors here and killed a fridge..my auto drain control on my shop air compressor is fried too but I didnt find out till weeks later..
I keep everything unplugged as much as possible 'cause you cant get anything from the power co for the damage

ya, the electronic stuff is VERY touchy with getting voltage spikes! Also its good to have them unplugged so the capacitors can discharge and cool down. I shut the computers off every night for that reason too.

Sonny,
, Build a rotary phase converter. static converters will only allow you 2/3 of the rated HP on the motor and I'm not too sure that a older motor would survive only limping on single phase. static converters only provide 3ph to start the motor. Here's the one I put together to test 3ph equipment. I still need to balance the Phases with capacitors to get them all tight but it will run a soft serve machine with a 3 hp compressor and a 2 hp beater motor. I have a bunch of 2hp 3ph motors if anybody wants one. (FREE just cover the shipping) The motor used for the converter needs to be at least the same size as the one you want to run so they're good for 2 hp or less.
The one I'm using for work is a 7.5 HP.
[Linked Image from live.staticflickr.com][Linked Image from live.staticflickr.com]
the button on top is to start the motor. pushing it provides power to the 3rd leg via a start capacitor to get the motor going. once the motor is running the button is released and the idler motor generates the third leg to run another motor or in my case a machine with multiple motors.
