- Thread cutting on the lathe. I know, I know, but had a few requests, thought I'd oblige. This is pretty general -- to help keep it clear and hopefully easy to understand/follow. Who knows, maybe it helps a few kids out.
Enjoy!

Dude, I work in IT and have never even operated a lathe, yet I love watching whatever you do in your workshop. It's pure relaxation therapy for me.

Same here
The arts and crafts are the best explanation I've ever seen for this concept. Good work man.
I don’t understand things unless they’re done in arts and crafts.
These videos honest to God have gotten me through some of the toughest times in my 19 years of living thus far. These videos always make me smile, as well as give me a ton of insight into how a *accomplished* and *efficient* engineer thinks. Plus that wing Chun reference at the beginning with the martial arts brought me back to watching old Chinese martial arts movies as a kid. Keep being great Tony, never change.
If you ever get married, you will be totally nostalgic for them. Happy wife, crappy life!
When you thought you already saw all of ThisOldTony's intros and you get this one 😵
Alex!
The intros almost better than the content lol.
When you notice people you’re subbed to on RUclips are also subbed to other people you’re subbed to
@@lukehome6206 holy shit I think that’s how I found tony too
@@daviddow5591 David!
Honestly, I find your videos far more entertaining than 99.99% of anything out there on TV...
If it weren't for Game of Thrones, I would've been upset that wasn't 100%.
;) Thanks Attila.
lolz double! :)
considering that each "GoT" episode of season 6 cost $10^6 you are still in very good position!
Just bought a lathe and turned my first piece of round stock. After years of watching this old tony I am pretty much an expert on the machine. (Only lost one finger to the chuck when spinning it up the first time but I can only count to 5 so I’ll just use my outher hand)
Within the last year, I also bought a lathe and mill, and have been teaching myself how to use them. Its alot more expensive than I figured it would be. But it’s awesome making anything I want
That carboard demonstration for 29.5° was one of the clearest explanations I've seen for any subject ever. Brilliantly done.
It was 6 years ago that I have watched this video and went down to my shop and cut my first thread!
Thanks Tony!
I don’t have a Machine shop or lathe of any sorts, but after watching this, I’m very confident in my thread cutting ability.
Young Creators ditto
Man I remember watching this video when it came out. It’s still just as good and the jokes are just as funny today. Love the vids Tony! ❤
I’m a field mechanic and I especially appreciated it when you said “weld it into your chuck... whatever it takes, whatever it takes.”
EXACTLY.
Thank you for using the cardboard illustration. That really helped me understand the purpose of setting the cross slide to half of the thread angle. Great video as always
I don't have a lathe. I have relatively no interest in thread cutting. But this was really entertaining and I learned some stuff.
Exactly that
üüüüüüüü\
Dear friend it is not some stuff but great stuff. Please don't get offended for my opinion,
And yes Tony, the artsy stuff made a difference.
I can guarantee you,and at least for me, a hobby machinist, i sure as hell didnt click this video for thread cutting
Thank you Tony for taking the time to present some of the best instruction and best subtle humor on You Tube. Those that understand, understand; those that don't, well they just need more life experience. Great work.
I started my time as an apprentice in 1946 at fitting and machining and of course went to Tech collage to learn the trade.
I had not worked as as a turner but spent most of my engineering days as a universal grinding machinist.
My nephew asked for help to restore a 1921 Benz car and I purchased a new small lathe to do some turning as well as being called to machine a couple of threaded parts. My old Tech days came to the fore and I recalled just how easy it was to cut a thread. Training well learnt. Carl Bliim Woy Woy Australia now 90 years young.
That's amazing Mr Bliim! Hope your project ends good!
For nostalgic reasons I decided to return to this: my first This Old Tony video... It's even better than I remember it. My only regret is I can't "thumbs up" the video again. Thanks again for posting such amazing content!
"Tony", thank you for the effort you put into these videos !! Explaining the way you do, and the added "visual effects", truly clarifies what you are trying to convey to us..... Recently bought a lathe and have been looking at MANY "How To" videos. Yours are among the best !!
Catching up on some older vids.
As an avid watcher - possibly a fanboy - I want to say that I appreciate your channel/vids a whole lot.
Thank's, man.
I'm a hobby machinist and do not have the advantage of formal training or an apprenticeship to draw from. RUclips has become the medium that I learn on. With that said, this is the best and simplest explanation of how the compound rest is used in thread cutting. Your paper stop action is a direct hit on my visual learning style. Thanks for taking the time to create this video, it answered many unanswered questions I had about cutting threads on a lathe. Your humor is always welcome and adds to the video, please keep them coming. Thanks Tony!
Thanks Crabby, glad it helped! Have fun and be safe.
I know this is an old video but I wanted to thank you nonetheless. Oddly I am an accomplished CNC machinist and recently got a manual lathe. I find it therapeutic and fun. I have been dreading threads on a manual lathe as I am so used to my CNC precision. Thanks to this video and about 20 scraps of aluminum I am now fairly competent with threading manually. Don't ask why I would elect to manually thread when I have a CNC - all I can tell you is that it is therapy for the soul. Thanks again Tony!
Repairing some large threads on a part that you can't find and have to pick up an existing thread. I suppose you could be real careful and do it on a CNC lathe, but there is a very good chance of crashing the bejesus out of it too. There is still some money to be made in manual machining, that's for sure.
Thanks Tony, your humor and concise speak makes it easy and fun to watch.
I'm a machinist and this is the best video i have seen explaining what happens and why a must for beginners and hobbyists
there is no way any one could make thread cutting more interesting or fun
Your simple arts and crafts just explain something I could never quite understand. Please don't underestimate the power of visual learning. Now I need a lathe.
I'm not even a machinist. And your videos make me laugh more than most modern sitcoms and comedians.
STOP
You CANNOT be this good at video making and machining. ITS ILLEGAL
I've cut lots of threads. Now, I wish I could go back and do them correctly.
The arts and crafts give the best explanation I've ever seen.
I love the style of your videos - funny, and complete project in one video. Excellent work
This video quality is immaculate. The info and how its relayed, is perfect. Thanks for the laughs and knowledge.
Great explanation and demonstration of thread cutting. Many years ago a friend taught me how to chase threads but with a slight twist. When I was about half way finished he stepped in and tore my set up down completely and said , now set everything back up and go in and pick up the thread where you left off. That was a good exercise.
for the puzzle, you throw some left handed threads for the bit that holds the two pieces together. that way it can be taken apart to win a bar bet, but when they try to take it apart they're actually just tightening it
-Perhaps- No, without question, the most fun and actual laughing out loud I've experienced on ANY thread-cutting video, ever! Thanks for the education!
I hadn't seen this. So I copied it, and gifted it to my father. He hadn't seen it either. You made an old engineer quite happy. Thank you 😊
I find your humour very funny, your videos extremely entertaining and what I learn in the process a bonus. Thank you.
I loved this video and I don't even have a lathe, I wish I had a workshop with all your fantastic tools.
Might be the fourth time I have watched this and I still laugh remembering my first time cutting threads! Thank you for the lightheartedness in such intimidating material. You are the punniest dude on the tubes; don’t ever change!
Being now 66 years old. I haven't used a lathe since I was 13. ...general shop in High School. Now there is a hobby that requires that I make things on a lathe. Someone suggested one of your videos, making a self centering machine vise. Even without the time travel, I am impressed! Here we are watching your third video,...I just thought cutting threads was some form of dark magic that no one in good conscience would partake in. But hey, it's easy!
I have one very important comment, actually a question, "Would you consider adopting a 66 year old man with a big beard?" I promise to make my own bed and generally stay out of the way.
BTW, decided to going ahead with the project to make a self centering vise. Making it from a common turnbuckle. If it doesn't work, I can use it for time travel.
Man This video is probably one of the best video's I have seen on youtube. Great editing, sound, music, etc.. You are top notch man.
Watching again and I still think "all the arts and crafts" was totally worth the effort. It made what seems a complex process much easier to understand.
Glad I found this video about cutting threads, I was curious how cut started at same spot. The arts and crafts part also made it that much more even clear about process. Thank you.
This Old Tony! The arts and crafts are always welcome. It was helpful for me to have a visual example. You make everything so accessible. This was another great video and I can't wait to see more! Thank you!
My same exact thoughts on the cardboard part, major light bulbs went off!!!
It's 2-22-22 and I have never seen these newfangled tacky machinist puzzles and appreciate all the content in this video. Thank you
I found myself with a new job that requires me to learn these skills. Thank you for helping me make my boss think I have more experience than I do!
I’m that one kid who’s never seen that puzzle. Congrats. Your video is a success
The traits of a good teacher are that you'll easily acquire far more knowledge than what's on the exam; you Old Tony, are a great teacher!
Very engaging, loads of dad jokes, and full of useful information. I don't even do metal working, but love watching your clips and demos. Great Work!!!
Thanks for the cardboard/craft bit, now I get why you adjust the top slide.
Same
Man your style of presentation is top notch, as is your comedic timing and sense of humor!
I had to stop this video half way through and just say, finally! This video is exactly what I've been looking for! It not only explains the how's, but the why's and the theory behind them in basic layman terms so even a knucklehead like me can understand! Awesome teaching video! Thanks for posting!
This is one of the best intros to a video I've ever seen
One of the best thread cutting vidjayos of all time. Seriously, I've watched Adam, Keith (Fenner and Rucker), Mr. Pete, and a few others "explain" cutting. THIS really showed it.
4:46 coffee came out my nose when you said "hearts and stars"! I've never used a lathe and still enjoyed this video greatly.
Wait a minute... Did I just watch a 30 min long video about cutting threads on the lathe? You are seriously talented at entertaining, keep it up!
also from 2-22-22, just happened to be learning about threading for my job. this video is a gem. thanks!
I'm only a kid in lathe years. Heck not even born yet, and this helped a lot. Thank you.
Brilliant! I love the way you made this much more interesting than most videos.
The 'arts & crafts' bit was very helpful! It did a very nice job illustrating why we approach at 29.5° & not just plunge straight in to the work.
This video should be used in schools!
I Absolutely love your videos. I don't even know anything about machining. I still watch your videos
Wow, great teaching. I learned more in 27 mins then 2 weeks of lathe introduction class in shop class.
thanks byrysh!
@@ThisOldTony Love your vids/humour.
I know you know there are many ways to secure these 'trick captive-piece mechanisms' so that even torquing the piece to deformation using tools/levers wont expose/break the 'trick'.
Try doing it on a threaded torus with 3 captive nuts, and do it so you can get them off if you know the trick. It took me months to get it just right, then somebody stole it, I never saw it again, I can't be arsed to make another because of 'most people I showed it to.. could not get what the problem was", even when explained.
See if you can figure it out. I'm not joking, it was a real thing.
Thanks for sharing.
Gotta be the most entertaining and educational vid of its kind EVER!!
If you're not a pro-educator, you might think about becoming one. You've got the knack for passing on info without the usual accompanying boredom and subsequent mind-numbness that generally results from instructional vids on this and related subjects.
Such a pleasure to watch (multiple times) - thanks a lot for sharing your passions and gift in creating these wonderful movies.
It made me so happy to see someone setting the tool at 30 degrees. Done right (like this) your able to leave a better finish on the loaded side of the threads... I would love to see you "forming" some threads...
Just wanted to say, I appreciate the arts and crafts visual aids. Makes it easier to understand.
Congratulation Sir, this is a spectacular tutorial on cutting thread. I happen to be a mechanical engineer, but I was not entirely familiar with this topic before. Your guidance is just fine gold.
Once again thank you very much for your time and effort teaching us newbies, even if some of us are in our late 60s and forget everything you said by the time your video ends.... great stuff Tony.
Wow, just wow!! The best videos on RUclips. Incredible humor but even better is the perfect explanations and wonderful photography which allows complex operations to be explained so clearly. I think you should publish in Hulu and sling and give up your day job.
Very good explanation. The paper cutting was informative. I hope you are a teacher as a profession. Your country will benefit from it! Thanks
i understood it right there, that made sense to me
I don't understand a word of English but I learned a lot more from your tutorial than from the tutorials in my language. hello old Tony from Italy
If you don’t, then....how did you write this
@@9bang88 big "G" my friend
Just got my first job as a machinist so I'll be binge watching these!
Excellent content!
Making a "captive nut" for a wedding anniversary. I see what you did there.
the special effect and humor are so cool! (I'm not into metal things, but that captivated me) Thanks for sharing your talent
Your video is perfect. The right balance of skill, tutoring, and humor. I learned more in 30 minutes than several sections of books I have read. By the way, the paper animation was perfect, low tech but got the point across perfectly. Why spend money on animation when stop action gets the job done. Definitely subscribing to you channel.
I fully agree. The paper demonstration was perfect!
NO! 17:35 I absolutely disagree. This channel has taught me so much that I didn't even know I didn't know. As an Electrical guy that has never and may never do machining work, your explanations open up a whole world of interesting and clever little innovations that men before me have discovered! Keep teaching, you're doing great!
Regarding the thread-dial, each of the numbered divisions (1 2 3 4) represents 1 inch of travel of the carriage.
And, subsequently, 1 inch of travel of the cutter along the work piece.
I hope that's not old news to everyone else, but I just learned it a short while back, and it was like an epiphany. It helps with understanding why different thread pitches can only stop on certain divisions of the dial. For instance, if you are cutting a 7tpi thread (they exist!), you can only engage the half-nuts on the whole numbered divistions (1 2 3 4). However, if you are cutting 8 tpi, then you could engage the half-nuts on any division of the thread-dial, down to 1/8 divsions (although most thread-dials are only marked, at most, down to 1/4 divisions).
This also explains why, when cutting metric threads on an imperial lathe, that you can't release the half-nuts at all, because there are no (common) metric thread pitches (.5, .75, .8, 1, 1.25, 1.5, etc...) that line up exactly with the divisions on an imperial thread-dial (1", 1/2", 1/4")...
... unless you are cutting a 1mm pitch thread, AND your thread-dial is large enough to have 254 divisions between each numbered division. If so, you could release the half-nuts at 10, 20, 30, ..., 110, 120,..., 250, etc... There are probably other exceptions to such a fantastical setup, but I've been typing too long as it is... :)
Words fail me. That was so well scripted and executed that even I think that I may understand. Not about to try to do it, but I'm slowly learning some of the mysteries of machining. Thank you for teaching This Old Tony and your guitar playing is getting so good that for a moment I thought that Django was right there, next the hampster, in the geary section of your lathe. You Da Man!
I have seen a lot of video's on thread cutting, and I think I have a theoretical understanding already. But this is the first time I hear the reasons behind the approach. Thank you very much!
please... dont stop doing "arts & crafts".
It REALLY helps learners like me 🙂
Hahhhh. When you took the cover off the lathe I lost it. I really wasn't expecting it. I love these videos
Me too. Love the puns and word play. I laugh more at these videos than standup comedians.
I just love this video. SUCH a good explanation of why you set the top slide angle. Thank you so much!!
That is so true; one must become an extension to the lathe. Whitworth .55° rounded peak threads. Years ago I knew Germans from Operation Paperclip who had a precision machine shop. They had a lathe set-up to kick out the half nut at the end of thread travel. They ran the speed of the lathe at high r.p.m. and the threads had a high polish. I have ground threads and grinding does a super job also. Threads can also be swaged similar to knurling. Your tool is plunged into the work as the half nut engages. I do use Tesa/Brown and Sharpe thread micrometers. They cut out alot of problems.
Just cut my first thread!
21.9mmx1.5 pitch external thread with 6061 bar stock.
It looks like a rough pineapple, but thank you TOT!
You were right there beside me. First cut. Many thanks.
Good job mate.
Loved the style and delivery. Very entertaining, but most of all I learnt a lot in just a few minutes. Fab. Thank you so much for your efforts.
I am from electronic back ground but the way you explained is extraordinary. Desperate to buy a lathe feel blessed even if I failed cut, failure is step to success
This was "Thread Cutting 101". Tony, I know people who pay for these knowledge. Thanks man, great video.
I've never been a machinist but after watching this 'tutorial' I feel that I am now a master in this arena.
the arts and craft way of explaining actually helped me understand thank you
No The Arts and crafts does assist in the understanding of the threading process.
Your unique collet while large seems very adaptable to the work you do. so we want to hear more on it and how it arrived as well. So many stories of your shop are worthy of a video.
Your restoration of the old iron is unique in that many people have never heard to the type of machine, and the fact you have converted them to CNC is a real plus.
Tool maker for 47 years, I must say I have never had so much fun in my life cutting threads! Think's for sharing!
That was the best intro thread cutting video I’ve seen! Thank you. PS: I’ve got a Clausing Colchester and would not have known about the half nut needing to be kept engaged on metric threading ( don’t have a manual for my machine) 🙏🇺🇸🗽
You have to regardless of machine make unless it's a metric machine
I watched this episode 2 days ago, and I'm still laughing about the bump in the electric bill.
Reminds me of my first welder !
Me to Electric Company:
"Seriously, You expect me to pay for this #*@$ ?. These welds are terrible !!!
This Old Your Highness, I just cut my first thread ever to that jazzy beat! LOL! Thanks so much for the channel.

When I was young I knew a couple of German engineers from operation "Paper Clip" who had a very fine machine shop and made parts for the rocket program. I was also making aerospace parts but in miniature sizes. They showed me how to rapidly make threads using a regular engine lathe with mechanisms to kick out the form tool and return it back to start so it would cut return then reset to a few thousandths into the work and it would do this over and over until the thread was done; all at a high speed in order to attain a very nice polished in tolerance finish. With their help I took some of their methods for repeatedly moving my tool in then out and fixtured a Foredom high speed handpiece with form ground threading stone wheels and ground my threads. I had to use a series of cutting wheels to rough out and final finish the threads but the thread forms were accurate and the finish was as good as their cut threads. I also made the custom thread mandrel sets i.e 30° trapezoid metric for my thread micrometer so I just ground and measured until I hit the gauge sizes. Once everything was set up to go it was like clockwork; I just put my parts into the lathe set the grinder to go then grind the threads measure them check them with the gauge and they were done when everything checked out for gauge fit and finish. I learned a lot of "Old World" machining techniques from those "Operation Paperclip" Germans. They have passed on and I miss them but I still have alot of their knowledge. Nice threading Tony. 😀
Start recording some videos. Pass on the knowledge!
"Though, unfortunately in this day and age, I'd wager that most people you show this to...probably would not get what the problem is" That is so true.
I really love the Bruce Lee/Karate Kid imitation there at the start.
I had only observed mesmerized a machinist operate a lathe when I was 15-18, you solved so many questions I had about the lathe, how it works and so many I would have had, had I actually done the work. So, thank you into going into all the detail you did. I learnt a lot!
the arts and crafts really helped me understand the mechanics of the process; thanks the video was great.
I don’t even know how to spell machinist or lathe, and I have no idea what you’re doing. All I know is, I wish I had real man skills like this. Your channel makes me feel small and useless. However, my saving grace is that I have a decent collection of drills, drill drivers and, my personal favorite, an impact driver. They look real nice in a bag in my closet.
Love yer channel. Thanks for compensating for all of us non-mechanically inclined, tool challenged lugnuts. Hey! I bet you can make those too!
-Dr. Mike
ha! thanks Dr Mike!
The opening to this video is just outstanding.
Absolutely love your vids ToT!
1.21 gigawatts on June's power bill! Brilliant! I love that if you blink you'll miss half the jokes. Great video!
Lol Tony you rock!! Started watching because of Ave's recomdations. Glad i did:)
Same
Ever since i saw a working thread and nut carved from stone at handwerkskammer mainz i've been fascinated. Regards to you Sir, thank you for sharing your knowledge, for captivating animations and bad puns, for your honest opinions and maximum respect for the nerves of a whole bomb squad while screwing arround with that cheap welder. It was a blast.
Regards to you Mainzer! Love that city!
I never cared about making threads. But i watched your video from start to end, could't even pause it! You explain so nice, and catchy.
All those subtleties about making an apparently "simple" thread, are fascinating..
We are taking things for granted, and we fail to understand how much science and skill there is, even in a so called simple thread on a screw.
Loved your video. Subscribed! PS. Disappointed there was no magic in the puzzle!! :-)))))
Here's an old timers trick. If the TPI of the treads you want to cut are divisible by the TPI of your lead screw then you can engage the half nut anywhere and the threads will be in time. Try it sometime. Put a piece of scrap in the lathe, set it up with any TPI that's divisible by your lead screw then cover the timing dial with something. I couldn't believe it either until I tried it.
I was with you as far as "simply"....
