As a former gunsmith, I've threaded up to a shoulder of a rifle barrel quite a few times... and have been "not quite fast enough" to stop the feed, and retract the tool simultaneously, a few times as well. I'd have dearly loved to have something like this when working on expensive barrel blanks! Clever design and very nice work!

I was proverbially sent at your pucker factor terminology 🤣 That aside, this is the most ingenious lathe tool I've ever seen, kudos! I hope you filed a patent before anyone gets any ideas!

What a great tool Sir. I'm only a hobbyist when it comes to machine shop work. My career background is pipe welder, tube welder, fabricator, and Boilermaker. I own a 1960 South Bend 13" lathe that had a lot of hidden issues until I actually did my project. I guess buying a lathe is worse than dealing with a used car salesman. I want to say thank you for sharing your work, if I ever am able to pick up a nice little mill I certainly will give this project a go. It was amazing to watch it work especially at 1000 RPMs

I am surprised I have never seen this before. Many lever activated retractable but never spring loaded! Thank you for sharing your prototype and thoughts! 👍

Brilliant KZfaq channel, Looks like a smoother thread because of the greater speed you can now use.

I'm impressed. I knew a guy who had a gadget called a snap tap. Very similar to what you built. I love the auto retract adjustable fixture you put near the chuck at the end. Brilliant.

I’m pretty new into the machining. it is always so good to see videos of guys with a solid work ethic and willing to put in the time to do the math, work, and finish complex thinking projects! Thank you for providing us with wonderful videos!

I do prefer mechanical systems for something like this, so this gets the tick from me Great work, and great tool

I just discovered your channel and love it. You are the Sir Richard Attenborough of machining videos. And bonus, you have a keen sense of humor. Great job! I’m an enthusiastic subscriber.

Truly an awesome addition to the shop! Great design and build. Now your bladder can rest easy.

I was curious and turns out that’s a fantastic idea well done well thought out

Nice exercise in processing! I've cut about every kind of thread on the lathe you can imagine, and you are right, there have been a few times the pucker factor came into play. I'm glad to report no permanent damage to the sphincter or the lathe.

That's some really nice work. I enjoyed your workaround solutions to deal with vise limitations. The design is intriguing as well.

Absolutely brilliant and now I have another project. Thanks for sharing this video with us.

Absolutely amazing. Your creativity never ceases to thrill me- it's a joy to watch you work, mentally and physically. Thank you for sharing!

Ingenious! Now, all you need is to make a stop, attached to the lathe bed, so that you can set it beforehand, and when the tool gets to the point where you want it to pop back, it touches that, and the device is triggered. You don’t have to do anything after it’s set. You’ve got me thinking about this, so I’ll go to the drawing board, and try to make something like this. So, thank you there.

That is simply amazing! Fantastic design and execution! Subbed!

Terrific piece of conceptual engineering. Absolutely spot on with your brilliant idea an execution.

Outstanding design. Thanks for sharing! Scott

Loved it, the process of making it even more. Congrats!

Brilliant idea and excellent execution, congratulations man!

Amazing! Thanks for sharing. I enjoy seeing folks think outside the box.

I just found your videos watching the collet holders. I saw this alien contraption for threading and was interested. Now I get to see you make it! You, sir, deserve a sub and a bunch of thumbs ups.

That is a bit of an effort in order to take it from the drawing to the prototype. It is a wonderful tool. Threading at the higher RPM certainly improves the material finish. It’s a good choice of a threading tool retractor for softer material and cutting right up to the chuck. Thank you for sharing your idea and showing the steps to make it.

nice job, i´m designing my own lathe and now i'm in the part of auto feeding to make some threads and this video is so helpfull

I like your approach, designing process and machining. It is interesting designing and proving a design concept. Sometimes while in the manufacturing process of the parts of a concept design you may notice varies that were not considered in the design. These type of situations for the most part are solved by the machinist on the shop floor. I see this in your video and respect your knowledge and skill. awesome!

Just found you and what a ingenious tool, love it 👍 New subscriber and I'll be checking out the rest of your content too, thanks for sharing 😃

Great work keep it up ! You just got a new subscriber, I'm in my first year of apprenticeship as a machinist in Switzerland and I'm loving the job ! Have a blessed day

LOVED this idea!! Great work!!

You have got a winner. The “puckering” that you referred to, is something that I experience after more than fifty years. Now to find a way to get around the inch vs metric spindle reversal issues. I am now a new subscriber.

That was absolutely brilliant.

Wow! A fantastic prototype! Best be applying for a patent. Thanks for sharing your knowledge with us. Cheers

What a beautiful tool, I hope I get around making one like it. Thank you for sharing.

Ingenious, and very well executed!

That’s some good machining and great idea. My Colchester has the “Ainjest Quick screw” attachment so it can be used for Ext, and internal threads up to a shoulder it’s a great piece of kit.

Excellent accessory to the lathe. There would be a definite market for this unit. I wish I had the time and the patience that you have to built one..

you have a new subsciber, i like the way you explain something that reminds me (now grandpa) of my grandpa when he explained something to me 😊

I used to own a Hardinge HLVH, now sold. You could thread up to a shoulder with automatic withdrawl at a 1000 RPM !. All day long. However, the tool you made is excellent , well done.

This is proper incredible. Very well done.

That thing is genius. Great job

What a excellent video and I love the way your so meticulous in all you do, this the first of your videos ive seen but not the last. Keep up the good work, now to subscribe and hit the bell.

What an amazing project. Thanks for sharing this! It's very inspiring.

Brilliant! Loved that!

Great job and machining tricks. Well-done sir .👍

Beautiful great bit of kit as you would say

Very well designed and machined! Nice work

Super cool ! Love when people create a complex but simple mechanism. As someone (who probably never invented a tool in his life) suggested, You could start the thread from the other side, but I never did like that. Very cool. I willmsave the video and hopefully one day have the time to make something similar… That hopefully works as well !

This is fascinating. My lathe only goes down to 360, so a definite problem, this might solve. I just have to decide if I can adapt one. Great to have access to the drawings.

I like your design and what's important it works on your machine. What I like about it is that the workmanship is so good and it looks tight. I'm still trying to find a good mill and lathe and get to working on it. I have many projects to accomplish. I hope that I do as well as some people. I am trying hard to find a quality machine too, I like precision and accuracy.

Lol! The pucker factor 😂 that was an excellent way of explaining that. Subscribed 👍🏻

You absolute gent, I've been searching for a free physics simulation for mechanisms all weekend. Algoodo to the rescue!

Excellent travail monsieur . Un grand salut de casablanca " Marocco"

Wow, it´s a fantastic work. Thanks Sr.

Absolutely brilliant. Well done sir.👍👍👍👍

Commendable, and I'm impressed. Thankx for sharing

Congratulations, this system is very enteresting.

Exceptional engineering. Well done!

lovely little project now on my things to do list

Brilliant! Having experienced more than a few explosive puckers, I expect the time invested will be more than compensated for in reduced laundry bills.

A very intricate device indeed. Well done.

A new subscriber... Very impressive engineering and manufacturing. Congrats on a fine fixture. Fred Ontario, NY

Amazing workmanship

this is great work and craftmanship! thank you for sharing

You developed a great tool, simple and effective. I'm surprised that someone isn't marketing this product. I have been working on a different solution to the same problem. My plan is to use the output from a DRO scale to set an electronic stop which would control a VFD with a braking resistor. Your solution is far more practical for mass market application. Thank you for sharing it :-)

How to know if your machinist is really a machinist. Listen to their terminology. You don't have to understand the lingo, only recognize it. If your machinist says things like "pucker factor" you can rest assured, this is a veteran! I see all kinds of KZfaq vids of people machining at home. While many manage to achieve end results that at least look like what they set out to accomplish, this channel. I can say as a multi decade invested in this industry personally, is of the highest caliber! After watching the tail stock correcting series, I knew this guy was the real deal. He doesn't down play mistakes, and spite trying to lay out well in advance his plans taking into consideration the necessity of orders of operations, but down to details like avoiding re clamping work pieces if possible, and checking square and concentric before and after, he still shows and explains how and where things go wrong, and explains his plans on how he can do it better next time. If you learn more from accidents than getting it right, then you are top notch in my book! It's difficult to make entertainment content about material a person sees 40+ hours a week for many years in a row, and still be captivating. Yet this channel is one of my favs.

Very nice job!

Wonderful engineering. Thank you for the video

Excellent vid and work, thanks, I have been musing on something similar myself based on a bolt action rifle I once had which is basicly your very well thought out design, kind regards from South Australia

Thank you for the drawings

Man. You are a genius, but sometimes I have a hard time staying focused in your videos with some of the jargon you use that's not common in the US. Lol.

Brilliant design my friend. Never would of thought of it. Amazing! I am now a new subscriber!

another amazing project! wow!

That is fantastic! Takes some stress away and lets you get really close to the shoulder if need be. To be honest, I still clench when threading up against a shoulder on a CNC lathe.

Very cool and genius design.

That is simply genius!!

Excellent work-thanks for sharing🤓👍

Very nice job man 👍👍👍

Sir..... Marvelous engineering. I salute to your idea.

excellent! thats a really smart tool, well done. after spending years manual thread cutting and gaining more greay hairs than i deserve I an now spoilt and have a Harrison Alpha semi cnc lathe ..but still pucker when the thread runs to 0.010" from the chuck jaw at 1000 RPM ;)

this man is amazing love you work

Great video!

This is very good working tools, I try to make it, sir.

Great gadget, it makes things quicker and also you get a finish on the thread that's unachievable normally

Love the content so far. I'd like a shop tour please 😊

"Pucker Factor" I like that saying. I am glad the American Machinist is not the only ones using that term. Cheers!

Wow I like this. Might have to do one for myself.

Oxxxx, very good. This is cool job!

SPECTACULAR,VERY BEAUTIFUL,VERY GOOD

If you have a lathe with a kill switch for the chuck guard being lifted or the back cover being opened, you could extend the wiring to those switches and move it to the ways as an adjustable stop for when after the tool pulls outs it shuts down.

What a brilliant disgin 👍🌺

that is a very good sistem for treading any machines have this tool but its rare see it , you have make a good work mister

Obrigado por postar, obrigado por transferir o conhecimento, ( thank you for transfer the knowledge).

Design deserves all the plaudits below. Regards

Awesome Work. Greetings from Venezuela.

Another good video, thanks for sharing.

it was smart and it works fine good works mr

Great engineering. I have never seen anything like this.

Nice work!

Wonderful idea!

Great tool! you could ofcoarse start the thread from the chuck end and cut it towards the end of the shaft, thus eliminating the 'pucker' factor.
