All the mini lathes listed on this page are made in the same factory in China. Except where they have different features, the parts are interchangeable. In our experience there is not a noticeable quality difference between the brands.
The LittleMachineShop.com models 5100 and 5200 HiTorque 7x16 Mini Lathes are the best in their class. They have the most power, most torque, and a longer center distance than other lathes in their size range.
The 500 Watt (0.67 hp) brushless spindle drive motor provides tremendous low-end torque. And you can vary the speed from 50 RPM to 2500 RPM continuously in both directions. There are no gears to shift.
The cross feed and compound rest dials are graduated in 0.001" and 0.025 mm. The lathe is equipped with a 4-way indexing tool post set for 5/16" (8 mm) tools.
Real top and bottom half-nuts and a reversible 16 TPI lead screw provide extended threading capability. You can create every American Standard Unified class 2A inch screw thread from 4 to 100 threads per inch, and you can create every American Standard Metric class 6h thread from 0.25 to 8 mm pitch with the extra 21 tooth change gear that is included.
The Grizzly model G8688 is a 7x12 mini lathe. The Grizzly mini lathe comes with more accessories than most of the other mini lathes, including a faceplate, steady rest, and a 2 Morse taper dead center.
Harbor Freight Tools sells two versions of the mini lathe. The Central Machinery model 93212 mini lathe is a 7x10 mini lathe. (Harbor Freight uses a different kind of ruler from everyone else when measuring their 7x10 mini lathe because it is actually 4 inches shorter than the 7x12 mini lathes.) The Central Machinery model 93799 mini lathe is a 7x12 mini lathe. This is the same size as all the other 7x12 mini lathes. Harbor Freight includes a 2 Morse taper live center with their mini lathes. The earlier version of the Harbor Freight 7x10 mini lathe is model 33684. The newer versions have some additional guards, but are basically the same machine.
LittleMachineShop.com carries the SIEG C3 mini lathe. The SIEG C3 mini lathe is a 7x14 mini lathe, which is 2 inches longer than the Grizzly and Harbor Freight 7x12 mini lathes, and 6 inches longer than the Harbor Freight 7x10 mini lathe. The SIEG C3 mini lathe comes with a 2 Morse taper dead center. The motor on the SIEG C3 mini lathe is also larger than most other mini lathes; 350 Watts to the other's 250 Watts. And, the SIEG C3 mini lathe has a lever-lock tailstock, while most of the others require that you tighten a nut to lock the tailstock.
Micro-Mark carries the MicroLux model 84631 7x16 mini lathe. This is the longest mini lathe available. It has the 500 watt brushless DC drive system and a lever-lock tailstock. The cross slide and compound rest dials both advance 0.050 inch per revolution.
Homier Mobile Merchants previously distributed the Speedway model 03911 mini lathe. The Speedway mini lathe is a 7x12 mini lathe. The Homier mini lathe came with a 2 Morse taper dead center.
ToolsNow.com (Cummins Industrial Tools) previously distributed the model 5278 mini lathe. The ToolsNow mini lathe is a 7x12 mini lathe. The ToolsNow mini lathe had more accessories than any of the others, including a faceplate, a steady rest, a follower rest, a 2MT dead center, and a tailstock drill chuck.

I've been a machinist for a little over 18 yrs. I almost pooped myself 5 times watching this. Safety first. That lathe does not care about your fingers one little bit.

@crispy8329 4 года назад

"You want to start very gently when you are coming in with your tip!" That's what she said!!!

@proberts34 5 лет назад

Thanks for the demo. It was interesting to see the little lathe go. That's a pretty snazzy hobby tool you've got there. One comment mentioned order of operation. While his tone was snarky and he didn't provide any constructive feedback, he does make a valid part. If you plot out what you'll be doing, you'll making the job easier, more accurate, and safer. For your project, I'd recommend keeping the bushing attached to the large bar stock as long as possible with these steps: 1. Secure the bar stock in the chuck. 2. Face it. 3. Cut the diameter down to the largest diameter. Leave yourself a little room for finishing. 4. Cut the diameter down on the section with the smaller diameter (the section which is 6mm long) and build your radius in that corner. Leave yourself a little room for finishing. 5. Drill your hole to a sufficient depth. 6. Chamfer the hole, the end of the piece, and the part of the larger diameter section you can reach. 7. Cut the bushing from the stock. 8. Clamp the 6mm long part of the bushing into the chuck. 9. Face it. 10. Chamfer the hole, and the other corner of the larger diameter section. Two safety tips: 1. Please don't chuck your piece so shallow, especially when working with aluminum. If you chuck it tight and right on the edge, and push too hard with the cutting tool, you can dislodge your piece. And you never know where it'll go (or how fast it will get there), especially if it gets hit by a chuck jaw. 2. And please never wear gloves, watches, rings, wristbands, dangly necklaces, long-sleeved shirts, jackets, or loose clothing when machining on your lathe. Have fun with your lathe and I look forward to seeing future videos of your lathe projects. I'll also be secretly monitoring to see how it holds up, especially with some plastic gears inside it.

Order of operation! Work smarter not what ever that was

@CarpeVideum 4 года назад

Nice introduction! I just ordered this lathe, so I'm getting familiar by watching videos. Those tips about the parallel straightening bars and locking the work on the long bolt for extended turning are great.

@bikeman1969 Год назад

I would have made part at the end of the full size stock he had at the beginning then at the end just part it off

@RoughAndWretchedRAW 4 года назад

Won't be mean or cruel. It was interesting to watch the struggle and constant repositioning. But you could have set up your bar in the chuck nice and straight Faced it and drilled the hole then live center in the hole and done all the machining without all the flipping and working safely away from the chuck.

When you pull your arm into that work you’ll start rolling your sleeve back. Second rule of machine work- short sleeves.. right after safety glasses.

@joethurman2712 3 года назад

It’s rough starting machining work without taking classes, I’m assuming he’s been using RU-vid as a resource opposed to school. I think he’s doing great, definitely some saftey mistakes, but nothing in this video I saw could have been truly bad. If anything the little machine could have thrown the hack saw out of his hands. Thats called a real life lesson. Anyways, keep up the good work and keep learning my guy.

@m3h5l5 4 года назад

If you replace the battery on the calipers they will read much more accurately, the cheap ones cant function well on low voltage

@livefree6878 4 года назад

Interesting, I’ll try a new battery and test it with another set of calipers that I know is in spec. Thanks again for your thoughts, I’ll give it a try

@bilbo_gamers6417 3 года назад

Hacksaws can bind very easily and if that bound up while it was spinning it could break very easily. There's a reason why parting tools exist. Also please cover up your lathe bed if you're going to be dropping something on it. I don't know very much about machining at all but it literally says that in the instructions.

@19jaredbarsuglia81 4 года назад

I saw the Pittsburgh calipers and had to do a double on the title...”PRECISION” hmmm. I’m not sure I understand the reasoning behind the whole jig to hold the part at the end, you had plenty of stock before you cut it down. Just cut off a little larger piece than you need and that way you can do 90% of your ops from one side, then flip, face, chamfer, and done.

@marklinder9485 5 лет назад

ON THE LEFT, CAN YOU PLACE A PIECE OF STOCK, DOWEL, THRU THE CENTER OF THE MACHINE, SO IF YOU HAD A 30 INCH ROUND STOCK, IT GOES THRU CENTER. SIMILAR TO CUE BUILDING LATHE.

@bustednuckles2 5 лет назад

Yes but the hole is only like 5/8's inch or so around.

Does the lathe come with spare fingers, or, are they an optional extra?😕😠😬

Sorry my friend, you are breaking too many lathe rules, good thing your chuck key has the spring on it, you don;t want to know how bad that can turn out.

@livefree6878 5 лет назад

I appreciate your input, just out of curiosity for some constructive criticism I wouldn’t mind hearing some of your thoughts on which lathe rules are a problem. There’s not a day that goes by that I don’t learn something new.

@@livefree6878 Sawing back and forth with a hacksaw can cause serious injury on a lathe. These machines will tear you apart. I was fortunate that when i purchased my first 9" southbend lathe that my good friend was a retired german machinist, and i got the odd slap in the head but was thought so much tricks of the trade. be safe.

@livefree6878 5 лет назад

Thanks, appreciate the feedback I’m always looking for a better and safer ways to get stuff done. Thanks for the feedback

@michaelkeymont501 4 года назад

Live Free, the best constructive advice I can offer, in my equally limited experience, is that the snarky comments are the way that machinists have ENFORCED safety, for millennia. It is the very embarrassment that results from doing something wrong, possibly dangerous, and getting called out on it. It’s ribbing for all of the best reasons. It hurts in the moment, but that’s how the culture of machinists works to really embed in your mind how very dangerous these machines can be. It’s also human nature to point and laugh at someone who is less experienced... Some folks might also just be assholes... ;)

I have the Harbor Freight 93212 {7X10} mini-lathe. I broke a gear and can't find a video on how to replace the gear. It seems to be the top belt gear because the other gears are all there. T belt is loose and the bottom gear is okay. Do you have a video on how to change the gear? I imagine I will have to order the gear from Little Machine Shop but I', a newbie and I don't know what gear to order. The gear does have a key slot in it. Any help you can give me will be much appreciated. I have watched MANY of your videos, especially the ones about the mini-lathe.

@jean-lucelias2689 3 года назад

This is an entire video of how NOT to work on a lathe....

@BedsitBob 2 года назад

If you must hacksaw material in the chuck (not recommended), put a wooden board on the ways, to protect them from the hacksaw if it slips, or, as happened here, metal falls onto them.

So is this lathe worth the $600 price tag? Does it come with tooling?

@livefree6878 5 лет назад

I’m pretty sure the lathe came with tooling. I know I’ve made tools and I think I’ve also purchased a few as well. I think the $600 price tag is worth it to me because I was able to fix a printing press that was going to cost me over $600 to have the pieces made. In my case it paid for itself, On this job alone. Since then we have fixed and repaired many jobs that we would’ve been able to if we didn’t have it sitting there. It is also valuable that the Lathe is very transportable. I’ve had to move a lot of lathes in my day, Two people can move this with absolutely no trouble at all. The way I look at this lathe is it has the size capacity can handle a lot of jobs. If I get stuck in needing a part bigger than I find somebody with a bigger lathe. At $600 it would be a difficult purchase if I didn’t need the work done, but I’m really glad that we’ve had it through the years.

@marklinder9485 5 лет назад

thats up to you if it is worth the money. keep in mind, the grizzly mini model has ALL PLASTIC GEARING! see the review. the guy shows broken plastic teeth on the gears and he replaced them with metal, his own cost

@JbassPlayer28 4 года назад

Why would you take down the OD last? Face>drill>turn OD>parting tool. Seems like you're not using the lathe effectively

@ajsironworks3937 5 лет назад

Hey is this lathe still working? Looking at getting one

@livefree6878 5 лет назад

Yes, it’s still working. My favorite part about this lathe is the size. If you need to move it it doesn’t take an army. Even though it’s small there still a lot of really good projects that are possible. If you have any specific questions let me know.

QUESTION, CAN YOU CHECK IF ALL THE INTERNAL GEARS ARE MADE OF PLASTIC? THE GUY REVIEWING THE GRIZZLY SHOWED THE INTERNAL GEARS, ARE PLASTIC ON THE COMPARIBLE MINI LATHE BY GRIZZLY. SEEN ON RU-vid

@livefree6878 5 лет назад

I know the gears that control the thread pitch are definitely plastic. I haven’t had a chance to pull it apart to see you but the gears are made of yet. Luckily I haven’t had to, we’ve run a lot of parts on this machine. The harbor freight milling machine I have pulled it apart. All the gears in it are metal except for one. There is one gear between the motor and the gearbox is plastic. I know this because I broke it. At first I was disgusted that they made the gear out of plastic. But after I thought about it I’m glad it is plastic because I’d rather have one gear shatter if there’s too heavy of a load. It’s easy to replace one gear. I am kind of interested to know what the gears look like inside the lathe. If you find out before I do please let me know.

@bustednuckles2 5 лет назад

All of the gears are plastic. It also comes with some extra gears. This has not been a problem for 90% of people. If you insist upon having metal gears, they are available at The Little Machine Shop .COM. You will be spending lots of money there anyway for tooling and accessories. As a matter of fact, it is very, very common to exceed the original price of the lathe buying tooling and accessories. If you do buy one, immediately get another cogged drive belt coming for a spare. You will thank me later I guarantee. Try to find a used machine if you can, the price of new ones jumped considerably.
