Can anyone give me any info on this?!?

Thank you all for the advice. You have no idea how helpful it is to me just to even having a sounding board. Everyone I know in my area know absolutely nothing about lathes or machine work for that matter. I've just kind of self taught myself for the last couple years.
This all started because I build high performance chainsaws and do a lot of porting. I had to learn to operate a lathe just to cut the squish band and base on the cylinders before I did the port work to get the compression ideally somewhere around 200psi. It's amazingly hard to learn by face cutting 4" into a blind cylinder when the biggest tool your first lathe would hold was about 1/2". Using a 1/2" boring bar hung out 4"-5" on a machine that the slide and cross slide where about wore out on with a bunch of slack and slop was an adventure to say the least. My God the chattering and gouging at first was unreal. I probably destroyed my first 5 or 10 cylinders lol. Took me somewhere around 3 hours to get my first cylinder chucked up with the run out as low as I could get it.
Some of my first attempts. Ahh what I learned in those early days. I thought the compound was supposed to have a bunch of play in it.

Cool, that lathe will probably serve you well for a long time.

I bought my first lathe to support my racing kart engine building business. This community is full of folks with lots of diverse interests so you’ll probably find others who have been where you are.

Go get it and post lots of pictures.

Loaded without incident. Just have to make it 3 hours to the house and get it unloaded safely.

Nice.

The more I look at that logo though (your photo of the handle is great) the less I see “Noor”. So I poked around some more and found “Nodo” lathes. Check out the logo on the left of the photo….

Congratulations and good luck!

Great find!!

Well, we got it home...after my Cummins had injector failure still 50 miles from home. It started pouring rain while we were waiting on a tow truck. Luckily I had seen the rain in the forecast and wrapped the lathe in a tarp and pallet wrap plastic. So all in all it ended up taking 16 hours to make the trip, be broke down for 3 hours, $300 tow bill, 2 hours spent in the pouring rain getting it inside, but it's here and in the shop.

About to go out and start evaluating the electrical situation. The wiring all looks to be a complete mess. The switch at a minimum is broken and there are loose wires.
All of the gearing looks to be in great shape and everything spins freely.
Everything seems to move freely and be really smooth.

I'm guessing this had to be the On/off switch. Which seems wildly dangerous to reach over top of whatever your spinning to turn the machine. Someone throughout the years has replaced the 2 or 3hp motor that came on it with a smaller 1hp motor. I have several 3 to 5 hp electric motors on hand if this one doesn't have enough power but it appears it been on this machine for a long time. So it must power it just fine. This wiring on the other hand looks like it's going to be near impossible to figure out without a schematic of some kind.

Nice….

Pro tip, rather than spending the next six weeks trying to figure out the original wiring replace the motor with a 3 phase and VFD.

Is a three phase motor that much easier to get wired up?? I'm not very well versed in three phase. I mean I understand how it works. I've just never messed with anything three phase.
I'm guessing this machine was probably three phase originally?? I can't find any info on it.

Your lathe, like mine may have been originally designed with a single phase motor. If you have a control box with contactors and relays to control motor direction that would be a dead giveaway.

You can get this working, and others here @markba633csi will probably chime in if you start a thread trying to decipher your machines original wiring.

But, wiring up a three phase motor with a VFD is pretty much dead simple. You run 240v single phase (dryer outlet) to the VFD and hook up the three wires from the motor to the output.

From there you can wire any of the original switches on your machine to do what they originally did with pretty simple programming, or simply use the VFD control panel to control direction and speed. It can be as simple as that, or you can control how quickly the motor starts and stops, wire in proximity sensors or any number of other functions.

Used three phase motors are pretty common (often in industrial HVAC equipment). You can get VFD’s from many different suppliers but I’ve had decent luck with cheapies from eBay.

Lots of us have done it and can help if you decide to go that direction. Variable speed at the twist of a knob is super convenient when dialing in a cut, I’ve done it on two lathes so far md wouldn’t be without it.

Cheers,
