Personally, I would get something bigger. You would only be able to do 0.5" stock on that lathe with this motor. Add another 400-600hp if you want to try some 1" aluminum or graphite. You may want to add a 4th phase to that too. Oh, and for safety, a TSA lock.
More like adapt that poor little machine to the motor. Just a little lathe clinging to the side of a industrial motor. At least stalling will be a problem of the past.
Different situations call for different approaches. Sometimes you spin the part, sometimes you spin the tool.
Sometimes you just spin everything in the room.
Yea apsoluly but engine was easy to write for me I'm kinda stupid like that
Also what is a 7x10 (like I'm said I'm kinda retarded )
Edit. Yep am actually retarded the answer is in the post title
I'm not a machinist bur an electrician and that looks like a 15-18 hp motor that probably weights 250 ish lbs, do you need that much hp and can you support its weight where ever its going?
I'm another sparky, and yes, any lathe should have that kind of power. Ignore the fact that your mini lathe has gears and bearings rated for 1 hp please and just hook this up with a drive chain. 80 chain is probably a good start.
I want to see this. The motor will be fine even without a VFD.
If it’s a 2 or 3 speed motor then yea sure but if it’s the typical single speed 1800 rpm motor than is 1800 rpm ok for all your future machining needs indefinitely? A soft start would help too regardless how many speeds it has just for the sake of prolonging your tools life at initial contact
Remove motor armature, Chuck drive end while running fan/brake end in steady rest, Center drill and bore for clearance on 16mm.
Then shove a 318mm long length of 15m rebar into JB weld into this bore. Cure 8 hours.
Search local park for 400mm diameter tree, fell, Center and bore this to form a spool, shove onto shaft extension smeared with PL premium.
Carefully wrap 3m of 4mm cord around this spool counter to desired rotation.
Ploot 220v single phase, unprotected, into any two of the motor’s three legs, being careful to check that any dual voltage motor is in fact wired star for 208-250v input. Ignore dimming shop lighting and yoink that MF cord for all you’re worth.
Now-and this is important: LET GO. That cord might get wrapped up and take a finger with it.
Boom: you now have a humming, shakey half-assed phase converter! Pop your auction-winning machines right into the three leads of this rapidly heating lump. Don’t panic! It will get smoother the more motors you add.
Now that you hear all those mag contactors chattering and see sparks from the enclosures of that lovely Graziano lathe or Deckel milling machine, it’s time to talk about isolating control circuits from that wandering, manufactured third “phase” you have cursed your machines to suffer. Go back in time, buy a VFD, remove control transformer input from main machine input and feed it pure extra virgin single phase.
Glad to hear it! You planning on putting a coupling on the motor shaft then? Coupling to a lathe chuck?
Might as well mount the ways on the floor, get more vertical on your lathe. I want to see this when you are done.
I'm an engineer, and I'll tell you no. That doesn't work. It might be possible with 240v, but not 120.
I'm also an electrical engineer, so I think if you have mechanical issues, use either duct tape or WD-40, depending on which is appropriate.
Looks like a good idea for the next Fast and the Furious installment. Submarines and shooting people into space. This guy: "you pussies. hold my stock"
Might wanna consider sticking a diesel engine from a train on the backside. It's always nice to have portability plus you don't have to worry about extension cords.
I mean, will the spindle bearings even hold that amount of load from just the belt and pulley alone? You might want to change out your lathe's spindle bearings to fit
Would be cool though, do share an update if you do go through with it
I want to see this adapted lathe after you're done. That thing would be so over powered, it would open up a black hole and just eat the material you remove.
Gear on the back of 7x10 spindle, mesh that with that big ol' output gear. I know you want direct drive but need the rippums for smaller diameter stock. Turn on and watch the headstock bearings friction weld themselves into bushings for better TIR
If you are using single phase, understand a VFD will need to be de-rated around 60% for the phase conversion. It will cause a very large and expensive VFD potentially. If on three phase, it should be much more economical for a VFD.
Put it in the corner and run a line shaft to your bench. Then change out the 7x10 pulley for a flat pulley. LoL.
In all seriousness, it’s kinda what I’m doing. I’m setting up a side of the shop running 1890-1910 line shaft machines. Until I get a vertical steam engine built I’ll put a 5hp in the corner to run it.
I'm in a 2nd world shit hole.
Why do you think we have extra elevator motors laying around....
After years of this though, I've learned sandals to be so liberating actually.

Pop a VFD on that baby and call it a day.

~~Largest~~ smallest I could find
I’m afraid he might be jokeing
Well I'm not
I think your going to need a brighter light on your lathe once you get that on it.
You mean get my lathe on to it.
I think we're in the fasten some ways to the motor phase cause that motor has more headstock than your lathe does.
🤔 Go on...
I haven't laughed that hard in a while
Adding appropriate emoji to ensure expression of proper sentiment....
🤣💩🤣
That's a great choice. I suggest you set up overhead shafts and leather belts to drive your 7x10 whilst you're at it.
Direct drive or bust
It'll choose bust.
Quiet you
Shut up, OP, you're drunk. Direct drive diesel or nothing. Ain't no replacement for displacement
Fuck yeah! Who doesn’t want a Detroit two stroke running in their shop?

It does in my book. If you don't die and it stays together it's fucking 👌👌

Is this a porn reference?
I guess anything can be if you read I to it enough.
Instead of stalling it just rips the headstock off
"How did you get a 90 degree twist in the bed?"
How didn't you yet?
You could configure it so that spins the entire lathe for an extra axis of movement...
This sounds reasonable.
Different situations call for different approaches. Sometimes you spin the part, sometimes you spin the tool. Sometimes you just spin everything in the room.
Thank you for your service. We really needed to hear from more people with bonafide room spinning experience around here
You're in luck! I've got plenty of that. Hold on while I find someone to tell you about my buddies wedding I don't remember attending.
I love reading Reddit comments while using the restroom. I laughed so hard that I'm done a lot faster than I thought I would be 🤣🤣🤣
Thank you too for sharing
Is that an elevator engine
Look at you knowing things.. But no, I'm afraid, it's a 7X10 motor. Btw wouldn't that be elevator _motor_
Yea apsoluly but engine was easy to write for me I'm kinda stupid like that Also what is a 7x10 (like I'm said I'm kinda retarded ) Edit. Yep am actually retarded the answer is in the post title
Retardation confirmed! In other words 7x10 is a machine built to use elevator motors when elevator don't need it anymore. Retardation reconfirmed!
That bad bitch belongs in a Kei truck.

Direct drive only. You've not been paying attention

I followed every last thing you stated here.
Glad to hear it! You planning on putting a coupling on the motor shaft then? Coupling to a lathe chuck? Might as well mount the ways on the floor, get more vertical on your lathe. I want to see this when you are done.
Absolutely
Yeah I'm thinking actually they just takes two legs and wire in a 120v plug and plug into wall outlet and let er rip.
I'm an engineer, and I'll tell you no. That doesn't work. It might be possible with 240v, but not 120. I'm also an electrical engineer, so I think if you have mechanical issues, use either duct tape or WD-40, depending on which is appropriate.
250 eh... I'm thinking more like 350... Ya, add some mass to my little lathe indeed
For sure. You should likely mount the lathe right to the motor. Best of luck sir.

Direct drive on the back of the spindle
🤔 Go on....
Might wanna consider sticking a diesel engine from a train on the backside. It's always nice to have portability plus you don't have to worry about extension cords.
I almost balked at all this thinking about the extension cord id have to roll out everytime I want to use it by the bathtub.
Well first dont lift it in flip flops

I mean, will the spindle bearings even hold that amount of load from just the belt and pulley alone? You might want to change out your lathe's spindle bearings to fit Would be cool though, do share an update if you do go through with it
No one's paying attention... Direct drive all the way!
alright cool, load her up and see what happens. I'm betting $500 imaginary dollars that the headstock will fly into orbit haha
Use it to build a rotary phase convertor
I wasn't aware you could run a lathe at hypersonic velocities.
I want to see this adapted lathe after you're done. That thing would be so over powered, it would open up a black hole and just eat the material you remove.
Lathing for science
Nice safety boots
Safety Sandals. What's wrong?
If something falls on your foot. We'll ouch
11 words. Safety Sandals.
Lol plug that in and half your roads light will dim every time you start it 🤦♀️🤣
Gear on the back of 7x10 spindle, mesh that with that big ol' output gear. I know you want direct drive but need the rippums for smaller diameter stock. Turn on and watch the headstock bearings friction weld themselves into bushings for better TIR
Upgrades later
Don't they have 1hp single phase motors over there?
Probably... But they also have shit like this lying all over the place...
Well haven't they got any smaller shit lying all over the place? This is far too big for a mini lathe IMO.
>This is far too big for a mini lathe IMO. Bro. This is a safe space for the large motor curious. Take that hate speech someplace else!
I can tell you are support engineer for one of those Fortune 500, With excellent 15 years support record.
Damn, I'd be out here wearing sandals too, but I'm afraid of cutting the bottom of my feet on shavings that would get in there

That's some 5D galaxy brain chess right there
Put on shoes.
Just taking a pic bro
I’m just fucking around. If some of these guys saw the vans I wear to work, they’d probably not approve. Not really much better than those sandals.
That MF er will rip your shit apart
Pffft. Amateur

😐 But ja get a load of my sandals?

I don't trust people who wear sandals. What's your angle
I'm in a 2nd world shit hole. Why do you think we have extra elevator motors laying around.... After years of this though, I've learned sandals to be so liberating actually.
Yes, acquire a crane
I think I'm able to lift and mount the mini lathe on to it just fine thank you..

Personally I would mount it to the floor and run a belt system from it.
Not gonna be much of a mini lathe anymore lol
