Another Thread Cutting Video?!

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.

The arts and crafts are the best explanation I've ever seen for this concept. Good work man.

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.

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!

[@corndog6700]

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.

[@silverdrillpickle7596]

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.

[@carlbliim4456]

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.

[@crabbyfrog]

I'm a hobby machinist and do not have the advantage of formal training or an apprenticeship to draw from. KZbin 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.

[@johnbasson2195]

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.

[@jpooch00]

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.

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.

@@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.

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.

Can confirm, I made a thread puzzle just like that about ten years ago in a college class, not class material, 'on the side'. When the admin people came around for a tour not one of them saw the problem. At best I got some "oh nice threads" comments, it was also polished so the rest were ooo shiny.

[@cameronmccreary4758]

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. 😀

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... :)

[@cameronmccreary4758]

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.
