Auto Retracting Thread Cutter.

This is how I made an experimental hi-speed thread cutter, it is designed to be mechanically triggered so that it retracts away from the threads to a safe distance, It was designed to be simple and repeatable.
The thread cutter will allow the threads to be cut at a fairly hi-speed and give me plenty of time to stop the lathe afterwards, I also wanted to get away with altering the tool post just to cut a thread.
Cutting a thread is now cleaner, easier, faster and safer than ever before.

In my videos, I show you what I went through while making the items, I never tell any one how to do things, because no two people have the same equipment, materials or time.

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!

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

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!

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

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 YouTube 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.

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.

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

[nviw]

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

[johncrisman]

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.

[brianlrayburn]

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

[robertqueberg]

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.

[DudleyToolwright]

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

[jmtx.]

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

[edwardhugus]

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.

[hypersphereengineering]

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.

[rogerwilliams]

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.

[kevinmaiorka]

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

[phillipjones]

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