Never did I expect to receive such an excellent lathe. This came with everything. I literally had to buy no additional tools, measuring equipment, or any accessories. All I had to do was insert my aluminum stock, use what came with the lathe, and begin to produce products.

Very good quality, should include a 3mm key way as well as the 4mm keyway then it would be a much better fit for my application.

I was surprized how nice this Mini lathe is . It comes with so many extras like a 4 jaw chuck and a quick install tool post. Takes awhile to set it up properly but I am now turning quality items with a very good finish. really enjoying learning about metal lathe work. Very satisfied with my purchase.

It’s not perfect but it was perfect for what I need. I suggest taking apart each moving part and re-assembling to make sure all bed ways are secure and no slack. If you do this just right you can achieve .001” tolerances. I suggest re-centering your tailstock and inserting set screws that are included but not obviously marked for tailstock. I suggest buying an accurate yet affordable DRO for your carriage. I bought mine here: https://www.amazon.com/gp/aw/d/B08LB5W41R?psc=1&ref=ppx_pop_mob_b_asin_image. It fit perfectly once i removed the chip guard. I 3d printed a part to fit around the head of a screw behind the carriage. This piece was glued to the slide on the DRO (see photos). Installing only took 2 screws and it allows me to get .001” tolerance along the carriage. Also note you need to properly ground the machine. If you do not have a metal table then you will need to splice the ground wire inside the machine and ground it properly. All in all if you do these few things you can really maximize your efforts on your lathe. Great little machine!

I ordered this gear set to replace the worn plastic gears in my Harbor Freight 7x10 bench top lathe. The gears are functional and seem to have a good tooth profile, however there were two issues that merit the 3 star rating. First, as other reviews mentioned, the sliding transmission gear bore is undersized. This would be easily fixed on a lathe, however my plastic gears were stripped which was the reason I ordered steel ones in the first place. I was able to open the bore on a mill with acceptable runout, but that took a lot of set up time. Secondly, all the gears were packaged together in a plastic bag and placed loosely in a cardboard box. During transit, the gears were allowed to impact each other resulting in damage to gear teeth. This required some careful reconditioning with a fine, small file. At the end of the day, these gears will work for you, but be prepared to spend some time on modifications and clean up to make usable.

Well made for the cost. I’m sure fit and finish varies as they are imports, but I managed to get them all installed with minimal fiddling. Change gears in the head stock were awesome and made a great difference in feel when engaging. Gears for the lead screw fit well and made minimal noise.

TIR is .0005 on the spindle, tested after 1/2 hour of run time. Measurements were at location points three1. From the face of the spindle.2 from the 6 o'clock position of the thru hole at the rear of the spindle3 from the 12 o'clock position on the outside edge of the spindle. the three jaw self-centering chuck TIR is .002. So the 3-jaw needs some work. The 4 jaws independent TIR is .00015 which brings the TIR combined to.00065 this is totally fine for a mini lathe.Now for the negativesThe Shipping box while sturdy was insufficient to protect the mini lathe. The steady rests were not secured and they broke the Lathe safety shield. In addition the steady rests had bent adjusting hardware and seemed to come from another lathe.The tailstock is adequate but just barely. This needs improvement on machining as it does not fit flush on the V-Notch of the Bed. This could have been avoided and they could have made it a compound tail stock so as not to put the adjustment on the bottom which necessitates total removal in order to center it to the headstock.Tooling and supplied accessories to include gears.The tooling is fine, and you can use Sandvik-Cormorant, Kennametal, or Kodiak inserts.The 4-way tool post can use some finished work. It is adequate though rough looking.The quick change would be better suited if it was a steel Quick change, not aluminum. It is fine for soft metals such as Brass260 and 4150CMV. I did use the lathe to change a profile on a new M4/AR Barrel that was causing some issues with gas block fitment. The quick change held up to fit.The dial calipers are metric and are .02mmThe outside micrometers are metric .001 graduationsThe light will need a better 18650 batteryThe plastic gears are best changed out to the steel set that the manufacturer VEVOR sells. These plastic ones have not cracked yet.The lathe does both metric and imperial threading. I use it for 1/2X28tpi and 5/8X24tpi.The splash plate can use some width and depth modifications as it interferes with the compound rest/slide and the tailstock locking lever.If you are machining 304 do not use the quick change use the 4-way until you find a steel quick change. also, divide your standard cut depth by half of what your calculations tell you. Do not use any of the Assort fixtures as their QA/QC and fitment is inconsistent, missing parts and are made poorly. Nor will they fit this lathe correctly. Believe me, I tried but without the correct hardware which will most assuredly be missing, you just have a lump of steel. Get what you need from littlemachineshop.comThe drive motor can be replaced with a 700w one. Alternatively, you can buy a Baldor motor plate and get creative, and use a separate VFD 1hp Motor. You will have to make your own belt drive for the new motor along with an external VFD as well as reroute the belt but hey this is what I do for a living I make things.the three-star could have been a 4 but the shipping and the tailstock/dead center is marginal fitment. Used within its parameters this is an okay lathe for screw cutting and general lathe work of stock .750 or lessyou can fit .813" just fine or slightly more if you remove the spindle and run a boring bar through the spindle to get .830"Materials I have used in this evaluationBrass260BronzeStainless 304Aluminium 7075T6Steel 4150CmvSteel Mn65SS410SS416The purposes this lathe will fulfill.Light duty and small part fabricationSmall boring operations under 1/2 inch metric up to 12mm (any diameter larger induces a strain on the motor).Threading operationsBrass up to .750SS304 up to .5004150 up to .625Aluminum up to.500SS416/R 17-4PH also.500Expect to make many passes.Turning operationsThe dimensional numbers above apply here as wellI hope this review clears up any misconception about what this lathe can or cannot do. This is a light-duty lathe. I would recommend this if used in accordance with what I listed. if you are not making small parts then I would suggest a larger lathe with a 29-32 inch bed and a spindle bore of 1.5 inches or 38.1mm.STAR ratingsI give it 4 stars for the TIR of the spindle and 4-jaw supplied this rating is not indicative of others as it seems hit or miss with the current QA/QCI give it 3 stars for the tailstock and the 3-jaw chuck, the steady rests, the light as well as the backsplash interference, and finally the nylon/Delrin gearsThe lathe should come with a discount coupon for purchasing upgraded steel gears.Also, the swing over is 1/2 of what they list this may be enough to swing a 2-star if an advertisement is rated on a star system.

As a gun smith, I The wife loves these. They fit well and are fun to wear. this so that I can do old firing pins. Since I got, I have done 3. It is a nice little unit and the extras make it worth the price.
