Not exactly the same. The one in the video is from Harbor Freight, but i've heard the Vevor one works well for the price from a couple people now.
Today special guests Dan and Chirpy show me how to use a lathe. They brought over a Central Machinery lathe and showed me the basics. In part 1, it's basic operation and facing, part two will be a bit more fun. I don't lose any fingers today, so that was an extra bonus.
This convinced me more than ever I need to get making that gingery lathe. Turning stuff is oddly fun...

Part 2 here: ruclips.net/video/uIEuHiB_yF4/видео.html
You can BUILD YOUR OWN lathe! Here's how: ruclips.net/video/b0KpGtnaymo/видео.html
The little nub left in the centre after the facing operation means your tool height wasn't centred (that's also why it was chattering a bit). If you rotate the tool post so its facing the tailstock, and put a centre in the tailstock, then add some shims under the tool until the tips of the tool and centre line up, that usually is the right height.
Mini lathe will be my next serious tool... They are just too cool!
It was neat! My wife turned a piece to exactly 0.750 +- .001", very precise
"Coooool" is pretty much my thoughts too. Cheers to Dan and Chirpy!
Caution: A lathe is a gateway to a mill.
That's the plan... lathe, shaper, mill...
I am finding this out....tooo late!
WhaT comes after the big ten, 80 ton hyd press, heliarc Miller, mill and perfect circle torch?
Im guilty I’ve been thinking about getting one
If only I'd saw your comment years ago it would have saved me from a life in my man cave, and a empty bank account cos today I've had to buy a new set of machines cos my industrial lathe broke now I'm setting up a expensive new smaller one
With the lead screw not turning you can lock the caraige in with the feed lever when doing a facing cut. Also set your compound feed 90* to the cross feed for fine adjustments when facing. Have fun, I've been running my HF for over 10 years, having a ball!
Actually at 90 degrees you are moving per each dial graduation. At an angle you are taking off less than the dial graduation or finer adjustment.😉 10 years should have taught you that.😂
Are the new ones they sell at HF ok? Id like one but thats a lot of money if its garbage
Guys, you can't loose a finger using one of these lathes. The missing finger is on the bench, floor or stuck in a ceiling tile. Severed? Yes. Missing, no because you found it.
Sir, Great Video on learning to use a lathe. The illustration and demonstration were perfectly supported by your explanation. Thanks for uploading!
The blind leading the blind. Lol nice video though. Good camera shots.
The band is back together!!
Is it strange that with the "tenth of a grunt" or "either of a grunt" i know exactly how much pressure to apply?
It's a nearly flawless torque spec metric!
I'm huge in Japan I love that shirt it's just funny all around
Very interesting! Next !!!
As a professional machinist, and having a 8x14 lathe, they have their worth. The Right bros. would have thought they were the cats ass
Do you think.... lathe machines will be used in the future I want to buy mini lathe machine but I'm little confused
@@BB-km5nvjust my opinion but these manual lathes are old-fashioned however for hobbyists they will always have their place because they'll be a one-off part that you want to make or clean up because I've seen with 3D printing there's always clean up work to do and even when they get to the point that they're 3D printing metal you'll probably want to clean up a part by removing flashing or sanding polishing facing
@@BB-km5nvjust so you can avoid making mistakes, i think it would be best if you checked out reviews for any specific make or model you are interested in buying. Older or used is better, but new ones being sold by reputable dealers are a good bet, as long as you know via actual reviews what you are getting yourself into. And of course, better machines have a higher price tag - but that does not necessarily mean that lower end stuff cannot be made to be brought up to standard, but there is a tradeoff in that the cheaper stuff will need a lot of work - and thus a lot of time invested in them - to make them decent.
My first foray into this was also one of the most troublesome acquisitions I have had- an almost junked 9” x 20” central machinery mini lathe with no cabinet stand and looking the worse for being yanked about on a scrapyard. It wasn’t the purchase price of the machine that gave me headaches (it was sold with a few odds and ends on a pallet for quite a bargain) - it was the logistics of getting it shipped overseas by sea freight. Cost twice as much or maybe more from all the headaches I went through as I didn’t know any better at the time; had I known better, it would have only cost me a hundred or so. Never making that mistake ever again.
(On a somewhat related note, please Please PLEASE do NOT send overweight ‘parcels’ to a mail package reshipper. Do NOT do it, they only do air freight and will charge you an arm leg and kidney for shipping)
I LOVE YOU GUYS.....aNo safety guards....SAFETY 3rd.....LATHE LIKE REAL MEN....HELL YEA
Something from HF that works! Cool!
It works great!... after it spent a week with chirpy getting a tune up
Thanks for the info, one question why is the cutting table in 40 degree angle.
Thanks for sharing.
Not seen so many mistakes all in one place before. ;)
I recently recieved my mini Lathe,it was,for it's Price,Really Good,but i didnt noticed that the drivebelt was Mounted incorrectly and After a few Days it Snapped. Now waiting for a replacement from the Company,couldnt find it myself.great Video!
That's a bummer! This one worked pretty well, I was surprised
Paul's Garage I have Seen so much Bad Reviews (and my lathe is essentialy the Harbour freight lathe,we dont have Harbour Freight Here in Germany,but as much As i know they all come from the same factory in China.) But i was Really surprised How well it performed,even in comparison to the giant cnc lathe i usually have Access to. Hope you get Yours finished,it's Really Fun to use them!
@Dennis Young Just do not buy their metal headstock high-low gears. Way to much backlash on the low set of gears even the second set they sent. Not their fault just what they buy from China.
lathe looks a little unstable needs bolting down to bench.
Yeah it wasn't bolted down, just sitting there. It was borrowed or I would have a base for it
Very cool Paul. I am hoping to 3D print the molds for the Gingery lathe and the cast them in aluminium. Seeing these felliws show you some fundamentals was very interesting
Chirpy has some upgraded gingery lathe parts on thingiverse I think. Cae Chirp is his name on there i think.

Paul's Garage Thank you Paul. I have just checked out his site and am about to try to print some of them. Thanks again for the links.
Hi thanks for video I was facing some cast iron water pump impellers and noticed that there are not flat but have two hi spots 180 ⁰ opposite its like the chuck movement is going in and out could this be a fault with the bearing on the chuck head.i am not a engineer just a mechanic auto electricia .
thanks for this!
You don’t “lathe” on a lathe, you “turn” on a lathe!
You should not wear rings when machining
Paul I have a suggestion for some stuff you should get for the mini lathe I would get a caliper and a speeds and feeds book to get the correct rpms and surface speed
Thanks for the tip! I'll definitely need some good books

I actually know less now then before I watched this video.
So when he was actually running the machine it'd be helpful if you could try backing the camera up just a bit so people can see what it is that you're adjusting or moving to get the machine to do what you're making it do.
Ah yes. Forward...i like that
My gunsmith friend refers to the Gingery tools as, "How to waste your life building inferior quality machine tools."
The Gingery stuff was never meant to be elite Uber precise machine tooling, it was meant to get people off the ground and get started in the event that they couldn’t buy or afford the properly made machines. The quality is also subjective, and the only tradeoff is time and raw materials. And given enough time, skill and know how, one can use said Gingery contraptions to build better, more accurate versions.
I've looked those before I wasn't sure how good they worked. I might have to look into one, I could see that coming in handy in the shop. Thanks for the video Paul and your friends
I was very surprised how well it workes
Those WD40 cans is standing in the way of the train 🤷♀️
Good video but I think a softer metal would have been a little better for learning
I have always worked on a cnc lathe how much harder or different is it to learn how to use a manual lathe
Should have let chirpy show you
I have been looking at a bigger lathe. What did you like about it Paul? Any plans on buying your own? Lots of stuff can be made on these things. I think the 7x10 mini lathe from harbor freight is the one to start out with. They are gear driven but the gears are plastic. I was told that there are replacement gears that are metal for these. I just have to convince my wife to let me buy one. My unimat SL1000 just can not run stuff that big.
They do sell a 7x 12 on line to gain a few more inches of bed. It was actually listed cheaper than the 7x10 when I got it.
I know this is 3 years old and I don’t have time to check all the comments, but aren’t you supposed to center the cutting tool with the center of the part (vertically)?
James May wouldn't happen to be from indianapolis, would he?
You're talking about James May from Top Gear who is now on The Grand Tour
Please forgive my stupid question but presumably these techniques would work on a wood lathe too?
I believe there is some nuance to it as the way they take off material is somewhat different, as people working on wood lathes use handheld tools on a stable stand to work on the wood - the stand provides the rigidity and allows the user to control the tool to do whatever they need to. It need not be said, but one has to learn techniques to do so safely, and I think the majority goal is to avoid the workpiece ‘eating’ the tool into it.
Metalworking lathes have this precaution sort of inherently built in for rigidity reasons, in that if the tool digs in too deep, either the lathe screeches to a stop, or something breaks. It’s where tool and machine rigidity and respecting the machine’s limits in terms of material being machined versus speeds and feeds becomes very important.
I’m not sure but I think your speed on your chuck is to fast ? And with steel shouldn’t you use cutting fluid ? I’m new to this also ( I bought one last week ! ) but I was told to start with aluminum in that it’s more forgiving and easier to turn ! Just an observation !
I started with stainless first. Made a crap ton of mistakes. I tried aluminum for the first time and I was amazed at how ridiculously easy it was vs stainless
George Burns I found that brass and aluminum are the easiest for me
Did you have to degas those castings?
Maybe I missed it in the video because of my internet-obliterated attention span, but:
Why did you have the top slide at this angle? Wouldn't it be nicer to have it perpendicular to the cross slide to directly read out the depth of cut?
Or was it just set up for threadcutting (yes I was binging TOT lately) and you just left it that way?
Thinking about getting a small lathe for myself (actually, I have been contemplating this for 20 years now) and therefore watching some videos.
Now all you need is a REAL lathe lol
Well, at least I know about Chirpy, and working in a mess. Why, hippies?
Pete222 uses oil
coolant?
It must be freezing over there.
I can tell.
Yep, so freezing we just couldn't stop sweating 😉

Hey Paul. I have been trying to cast a sword out of aluminum, but it isn't working. I've tried vertical flasks twice just pouring from the top and the aluminum forces it's way out of the sand. I've also tried just a regular flask with a sprue (I hope I spelt it right, but I doubt it) and riser, but it only cast half of it. Any recommendations on what I am doing wrong and what I can do to get a successful cast? Thank you for all the great videos. Keep up the great work
If the vertical flask isnt tight, the head pressure can cause it to leak. I rammed the sand very tight and also screwed the flasks together. If it wont fill while flat, it usually means the aluminum is cooling before it fills the mold. Could be the pouring temp is too low, or you need a different gating method or something. Post some pics on alloyavenue or on my discord and we can help
Paul's Garage Alright. Thanks for the advice and I unfortunately don't have any pictures as I remelted it all into ingots. If it doesn't work next time then I will send you pictures.
I heard that you have to be a ginger to operate a gingery lathe -- is this true?
No idea. But I should be fine either way!
who else is here from that “video”
If you know, you know
Never wear long sleeve shirts!!
Visitors! awesome. Oh ... First. :-D
Can confirm first
God knows why you are turning with the compound slide at ( around a 45°angle) in the first place..... that is only for taper turning... plus its going the wrong way too.. the angle you have is for turning an inside bore..... and the reason you have a little nipple in the centre of the bar is because you haven't set your tool height correctly.... I'm a British engineer and I apologise if I seem like I'm being a dick... it's just (as an engineer) it has to be perfect within 1/2 a thou at least... I think chirpy has an idea of what he's doing mind x again sorry for the criticism, just has to be perfect man👍😉x
In the English language we "turn", not "lathe". Lathe is a noun, not a verb.
How dare you use aVe terms
That thing looks like its made in china if you know what I mean
🤣
Confusing video, too much talking, shaky camera !!
Somebody’s new here. HAHAHA
Ugh, the motion blurr is giving me a headache
Horrible too
Long
Awful speeds and feeds, awful tool height awful finish Jesus christ
Can you recommend a better video I'm looking to learn about running a lathe
Yours like talking more that action.
I only lasted 5 mins...too many people talking👎
SCAMAZON IS BAD NEWS PERIOD!!!!!! BUYER BEWARE, spend your hard earned money elsewhere
Pretty time wasting, I still don't know what to get away with.
I know this video is a little old....but you guys are dangerous. Those cutting tools are too small for that "Turret" adapter AND you aren't seating them back all the way. Even if it doesn't come flying out of the holder, you're running the risk or the cutter being able to move. NOT a good video to watch at all.
I'm looking for a good video to watch to get some Basics on using a lathe can you recommend a better video
Is it strange that with the "tenth of a grunt" or "either of a grunt" i know exactly how much pressure to apply?
