VEVOR Mini Lathe "Ragrets" (my regrets)...

- I'm making this video to put to rest the onging question of "so do you now regret purchasing this lathe?"
The simple answer is no, I do not regret purchasing this lathe. What the video covers is why I take that position. What's also covered in the video is what I do regret (and why), and that regret is purchasing through Amazon instead of VEVOR direct.
The repair saga continues...
hammering a spindle out is perfectly fine long as you have a soft material between then hammer and spindle, make sure each blow is done carefully so your hitting it straight on and that the soft block is being held flat to the end of the spindle. Alternatively if you still not conformable with the hammer way put long bolts through your spindle nose plate with the head facing towards the tail stock with a nut & washer on the inside, hold the bolt head still and slowly move the nut to apply pulling pressure and make sure you apply pressure evenly between each bolt.
I got a lemon 8 by 16 with a defective spindle, I drove it out with soft blow hammer and block of 2 by 4. The lathe won’t break
We'll see what Vevor says (Monday, hopefully?) but.... assuming this is in agreement with Vevor... this is what I'd do. Possibly obvious, but here goes:
Take a piece of pipe large enough to fit over the chuck, and long enough to get the chuck-side bearing out. Put this over the chuck and resting against the headstock casting. Some large rubber bands could be handy to keep it in place.
Get a piece of steel with a hole in the center to bridge over the pipe., and another one to bridge over the far end of the old spindle.
Into the holes in the bars, put a section of all-thread, and then put some nuts on both ends.
Turn the nuts to put tension on the all-thread. This should result in pulling the spindle out the front. of the lathe. It may damage the front bearing, but that will be not reused anyway (there's a new one on the new spindle). It may also damage the old copper ring that's press-fit on the spindle, but again, there's a new one on the new spindle.
Installation of the new spindle should be the reverse; except that you'll pull the new spindle in with the two threaded rings that you originally removed from the old spindle. You might need to flip the improvised puller around backwards if there's not enough threads on the new spindle to start the threaded rings before it's pulled into place.
As for raw-greets.... the only reason I wouldn't have bought this particular model is the direct-drive motor arrangement. That leaves you dependent on Vevor's electronics to drive it. I would have chosen one with a separate motor with a belt drive, so that any off-the-shelf motor & controller can be fitted.
I suppose trying to retrofit a pulley onto the spindle might be possible if you have a working mill at the time with a rotary table; so you could modify a cog pulley (aka, timing belt pulley) of the right size to attach to the gear that is driven from the spindle that turns the threading geartrain.
Just a block of wood on end of spindle and some taps with a hammer. Just remember it's a simple piece of equipment it wasn't made in a rocket engine factory.
I believe this old Tony might have some videos that can help you if you haven't gotten your problem resolved.
I received my MX-S716G2 months ago to this post. I opened the crate and witnessed the Bed Way completely snapped in half. I still have not received a return shipping label or any compensation. There is no accountability from VEVOR or the stores that represent there product. One hand has no idea what the others doing.
That said, I'm out 700 Dollars. And for the life of me I cannot find a replacement bed way for this type of motor config.. I'm still trying. That's my Vevor story.
Where did you purchase it from? Vevor has a 30 day "window" to return a purchase. Amazon also has a liberal return policy. A cracked/snapped/broken bed would be an immediate return from my point of view. Hope it works out for you. I have gotten my $700 out of my lathe in both learning and machining/creating. Once this one eventually fails, I'll purchase another.
It’s frankly simple it’s lightly press fitted
If they are made by the same factory, could you get a schematic from another brand's version? The important parts should be the same. Maybe there is online support/forums for their brand that you can use to fix your problem? I doubt my suggestion will help, but it might be worth giving it a shot. Best of luck.
You must smack the spindle out with a block of wood!
What was the real problem? that loose black ring ?
The magnet (motor?) that is "wrapped" around the spindle shattered.
You need a press and a bearing separator
