Went and purchased a milling machine the other day for the plant, BP clone step pulley and really clean and not beat up for its age, $1500.00.

While there I was shown a lathe, Chinese made missing the threading dial, said they ran into a problem with it not switching directions of the spindle. Other than that all was well with the machine. $1,000.00 I passed for the place I draw a check from.

Got an email from the guy a week later, $400.00, which comes out to 11 cents a pound.
I got a manual, spare 4 jaw independent chuck, 3 jaw chuck, wrench to change chucks, steady rest and a live center, a few pounds of chips to go with, chip pans and such to go with.

So I may be making a 3 phase rotary converter and specs should be what Cutter made for his air compressor. I have a 7.5 hp motor 3 phase for the converter build and the lathe one is a 4kw motor.

I do not know what delivery cost me as I asked my guy that owns a construction company about hauling it and He said I'll just go get it and bring it to you, he shows up with the lathe and a skid steer with forks and drops off where you see it in pictures. I have turned it over by hand and did not hear any funky noises, The place I got it from is in 5S mode and it had to go. He told me it ran fine they just got a newer lathe from a reorganization and it was a bigger machine.

So we will see how it came out, I should be able to figure out the controls electrical in the midst of rearranging the garage and such.

The CEO was so pleased to have such a large chunk of iron in the garage she was speechless, if only for a few seconds.

Pictures attached.

WOW!! 400 bucks and free delivery. That deserves a monstrous "you suck" .
It should be an interesting job figuring out the problems, wish you were close enough for me to kibitz on that. :-)

I'll agree with the running part. I am going to see about disconnecting the power in to the control transformer and working out the controls on the electric side. The control transformer take 220 single phase in and brings down the low voltage to pull the starters and such in. I'll check the motor for continuity and no grounds and that should take care of the electrical side. I do see a rotary type switch connected to the forward off and reverse control lever on the machine, that may be where the guy lost the reverse part of the control to reverse the spindle, We shall see. I'll bring you guys along as best I can going through the thing.


I still have to gather all the parts to create the phase converter. I have a small timer, and a 7.5 hp 3 phase motor.

Cutter, how long do you hold your contactor in when you turn on your RPC? I am referencing your RPC build thread in earnest now.

Yeah, for 400 bucks you absolutely stole that thing. And that isn't any ordinary cheap Chinese lathe. I'd be willing to bet that it's an early Taiwanese model--probably dates back to the 80s. That step in the gearbox was quite common in the early Taiwanese stuff as was the all Chinese labeling before the rules about labeling got more stringent.

Compared to a generic 14-40 mainland Chinese machine that is a far better machine. For starters it will be heavier; the typical 14-40 Chinese lathe will average around 1800-2000 lbs--Ill bet that one goes 2700-2800. The two cast iron bases add mass which provides a lot of damping when making heavier cuts. Measure the bed width and depth--some of the cheaper lathes are only 9-1/2" wide; that one will likely push 11" or even more. And look at the beef in the steady-rest and tailstock--not only are they heavier but even in the pictures you can see that they're pretty high quality.

What's the spindle mount? And what's the bore through the spindle?
