Well, I started to compare rates for new motors… Unfortunately, I cannot spend much money now. I was browsing the Craigslist and there is a second used motor that has features similar to my electric motor. Here the model

Except of the phase. I have single phase and this motor is for 3ph. The seller asks reasonable price. Have you tried to convert with VFD?

Wouldn't that be cool?!? In a flex-fuel model too

Those SU carbs on that B-18B engine were a neat design, especially after Volvo started using the Grose-jet float valve (237569-9 Volvo p/n) as a replacement for the original SU part. I met Henry Grose at his house and visited him a few times in his basement workshop. He lived in a very modest house in Stoneham, MA. where he made his Grose-jets from brass hexagonal bar stock. His secret (patented) to the long life of his float valve was the stainless steel ball at the tip of the needle. It wouldn't wear or stick like a conical brass needle would.
Then the nightmarish needle and jet. The more common needle was the DX (237315 Volvo p/n) but there were more than 10 needle sizes to choose from. The corresponding adjustable jets 237592 and 237593 ([front and rear respectively] Volvo p/n) were very easy to work on.... if you knew what you were doing. 1971 saw the first Bosch fuel injected models and that changed everything... right into the world of the super nightmarish electronic fuel injection

Sorry.... (I musta took lessons)

Please excuse our resident gearheads, but you'll have to stick with a 1ph motor. A 3ph won't work. You might be able to find a local electrical motor shop that would be willing to rebuild your old motor.

Fred, That motor shown is a C-mount motor, and if the 3 phase motor bolted up, you would still have to spend money for either a VFD (variable frequency drive) or, at the least a simple capacitor phase changer (and then you're only going to get 2/3 the rated power of the 3 phase motor. Stick with a direct replacement, or get your motor rewound.

You can get single phase motors for most lathes from Grizzly or (as bad as I hate to recommend these guys) Harbor Freight. Single phase 110 220 3/4 horse for a little over $100.00. With there 20% coupons it will be pretty cheap.

Did the lathe successfully run the way it is currently hooked up, or has it recently been installed where it sits?
Here's why I ask...
I obtained an Enco lathe 30 years or so ago used from a mechanic's garage that was going out of business, and the power was shut off there.
It had a 110v cord on it.
We hooked it up at home and it had little power/speed.
I took the motor to the local motor guru, and he said it was a 220v motor hooked up for 110.
He wired it properly and furnished a proper plug for it for $20.00
We then wired a receptacle with the proper setup and have never looked back.
It runs great to this day. It's a nice little machine.
Your mileage may vary.
