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!
Hi, thanks for your comment. I do know what you mean about missing the spot. There are now several of these that have been made around the world. All of them with a silght difference and I belive that one Indonesian country is manufacturing them. I think thats great. I'm happy that an Idea of mine has a place in someones tool box. regards
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 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!
Hi, I'm glad you enjoyed the video. A patent is as much use as a female breast on a mackeral. There are far too many countries in the world that do not respect the patent system. cheers.
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! 👍
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.
Hi, yes I have thought about this, but I have so many projects on at the moment that I’m not sure whether I’m coming or going… It’ll be good to see what you come up with..
@@Thesheddweller you and me brother. It’s a cascading problem. In order to complete one project, I need to make something, which triggers another thing I need to make, which gives me an idea for another project, and so on. I must be somewhere in a good dozen projects at any one time.
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!
Thank you for your comments, being new to machining is a great hobby/skill and if I can throw my pennyworth in I would say this as I always said to my apprentices. "All machines are living devices… they have one sole purpose in their life… that is to kill or maim you.. always be mindful of how to quickly stop the machine in an emergency… always wear PPE.. Never wear gloves while using a machine.” It is important to read all safety notices and/or a factories act. above all.. have fun.
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 TH-cam 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.
Hi Mike, Thank you for your comments, they are very encouraging. The problem machine engineering at home presents is that, one can very quickly find ones self lacking in resources, not just the material ones, but the skills that have to be very quickly learned, like draughting, material acquisition, filming, sound and so on. After what was a lifetime following orders,... (read a drawing and machine a given amount of material from a piece of material to achive the next stage in the process and pass it on for further processing at the next station.) I am lucky to have had the opportunity to have used almost all machines on the shop floor in an effort to remain employed during my working life. I enjoy working in my little shop and because there are a lot of Channels out there telling you how to do things, I prefer to show it how I do things with what I have. ATB..Cheers.
Hi, i have watched many of your videos i particularly like the gearbox and I wondered if i could make something similar for my lathe. I also found a large magnetic chuck in a skip, after taking it home I stripped it down cleaned it up and reassembled it works fine, but i’ve never used it, not yet anyway, they are bloody dangerous things to strip and rebuild.
@@Thesheddweller Plus the eletro-magnetic ones need a power cable that winds up around the spindle. 😖 I've used smaller magnetic chucks on lathes and I was always leery about using them. The tool grabs and watch out. Plus every time I used one I always took a very light skin pass across the the face as the chuck may have been used on a different lathe. I think Clickspring has the right idea of using cynoacurite for small thin parts.
Thank you for your kind comments, yes, the faster the thread is cut, the better is looks.. but, I must warn you that the faster you go, the pucker factor increases. regards.
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.
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.
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.
HI. Thank you for your comments. I’ve not cut a huge number of threads in my time, but one thing I do know, is that the two laws of probability ‘sods law and murphy’s law’ both play a part in thread making, doubly so when using thread gauges. regards
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.
Hi, Thanks for your feedback I've never really cut threads in my working life, because the stuff I machined was too big for threads, it wasn’t until I retired and started my little workshop that I realised how efficient a laxative that threading could be. At work most threads that were cut were done using big Die heads and massive taps, until the CNC turned up then everyone got a dose of the S***s.
The inch vs metric spindle reverse issue can be tackled with a dog clutch Google Meek screw cutting clutch, unless you have Myford you would need to develop your own implementation but the principle is there.
@@tonyray91 , Hello. I did look at the dog clutch that was made by Graham Meek. It looks like a great option. My next step is to find some drawings, as a start to adapt the concept to a 16” South Bend. I thank you for the suggestion.
Hi Robert, The Myford version is published in Meek’s book which is similar to what you would need on an SB model 9 but if the 16 has an internal reverse mechanism this might be more informative www.model-engineer.co.uk/forums/postings.asp?th=171112&p=3.
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.
Hi, thanks for your feedback. I have been approached by dozens of eastern manufacturing companies asking for my approval for them to manufacture this unit. I have stated and will continue to state that, everything I make or publish is open information for everyone to copy and must not profit by it. So I take it that variations will soon appear on the open market very soon.
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.
Brilliant! Having experienced more than a few explosive puckers, I expect the time invested will be more than compensated for in reduced laundry bills.
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.
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.
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 !
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 :-)
@@Thesheddweller A switch would work, but I already have a DRO and it offers some other advantages. I want to be able to start deceleration before the carriage reaches the actual stop location and need a method of measuring carriage velocity. I intend to use a rotary encoder to measure the velocity of the chuck.
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.
Hi, I just wish after building the shed that I had enough money to buy better equipment, but as in life one has to make the best with what one has. If I could wind the clock back, would I have chosen differently, yes I would have bought old British, German or American machines and refurbished them if they needed it. as I did with the my grinders and will do with the shaper.
@@Thesheddweller thank you, I was checking out your site this morning. What make is your surface grinder. I like how it was made for coolant, I wish mine had been built that way. I use a mist system, it works ok.
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.
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 ;)
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.
brilliant idea...... you have steady rod set at head stock to activate the retract lever but at the same time it is also necessary to disangage slide attached to lead screw
Love the ingenuity. Never seen anything like that. Personally though, I just flip the cutter upside down, run the chuck in reverse and then start the cut from the chuck moving toward the tailstock.
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
Hi, Thanks for your kind comments and thanks for watching. Machine engineering is a great career but, as you will find out, it can be a bit like (real) police work,... in a word,.. repetitive, except that you are rewarded with an end result, something that will probably last for ever. enjoy. PS. I'm just about to make another video for the two chucks, a modification.
Il y a quelques mois , j'ai découvert votre chaine . J'ai particulièrement apprécié la réalisation de ce porte outil rétractable pour les filetages . J'ai tout de suite entrepris la réalisation de ce dispositif en le modifiant pour le rendre plus compact . Les essais ne sont pas encore là . Dommage que votre blog soit fermé, je vous aurais bien envoyé quelques photos. De toute manière, je tiens à vous féliciter pour le travail que vous réalisez et pour les connaissances que vous partagez.
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!
FYI: George H. Thomas designed a retractable tool for just this purpose-( I think Hemingway actually have a kit for people to make it) and as you may well know- Hardinge lathes come with the feature in built. Love your content.
In my experience, spiral fluted taps are really only your friend in blind holes. Any through holes, I highly recommend standard straight flute, Japanese taps. Heavy weight oil on steel and stainless. Tap heavy is messy, but has proven itself superior to just tap magic. Clean up heavy is best done with some acetone, then some isopropyl, or that I had available.
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.
Is this what I'll be like when I'm older? Because I sure hope it will be. I can only admire the time and care taken. Time and opportunity in the shed has been sparse lately
This is my first video of yours. Looking at your other videos, I see that (despite being on here for four years) you don’t have very many. Please tell me that is going to change. You, sir, are fantastic.
Hi, thanks for watching, I have also built half a house in that time. Despite this I’m only able to make a video, one every two to three months, due to other commitments.
@@Thesheddweller There’s a lot of great machining content on YT but a lot is American and while I have nothing against our transatlantic cousins, pronunciations of aluminium, lever etc along with US customary units drive me crazy. I wanted to find a UK-based channel (preferably the North of England) using the metric system so I could switch off that pedantic, critical part of my brain and focus more on the content. (I know, it’s practically a mental illness - right?) Finding this video was brilliant especially while stuck at home all the time! You really check so many boxes for what I’d want out of a creator. Suffice it to say that I’ll be glad for any projects you have to share and you can count on an eager audience of, at least, one for any future videos.
@@sambishop3211 Hi, Thanks. To some, I chatter too much, others say I don’t have enough content. I know I make mistakes, but mistakes are made on TV as well. Its always good to have someone that is perpared to bash the keys and show their appreciation. cheers.

Nice touch, now I wont a Surface grinder and small Shaper, but most seem to be on the east cost, I know there are some here In California but they are not parting with them.
Ive been having really good results from running the threads backwards with the cutter upside down and running the lathe in reverse and starting the cut from the inside of the thread so once it makes it to the end of the cut its impossible to mess up. This is very interesting non the less. I like this idea for sure.
Hi, thank you. I’m glad you enjoyed them. As for the shop tour,…. Errrr,… wouldn’t you rather see the inside of my work boot,…. it’s not so cluttered. 🤣
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.
Great idea. Must say I've always gone for the quick wrist flick but then the bigger shoulders and shorter stick outs limit that at speed...or I give myself a root diameter groove to work to and make sure I'm ready to react! Either way, your system trumps the lot and the ability to work at a speed that suits the tips as a CNC lathe would, is brilliant! Congrats.
@@Thesheddweller I saw you say that in another comment. I take it the spring-out is so sharp you practically end up with a dead stop at the end of the thread? Job for the Mk2 version, cams out the thread depth in a single rotation and then jumps right out of the way. :-)
Great design, and even a better job bringing it to life. But I have one little trick to share with you. Shortening a tension spring and creating the loop is actually very simple. First determine how many coils you want to remove. use a Sharpie to mark the center between the two coils, the line up the mark on a 90 deg corner of a vise, and give it a quick rap with a steel hammer. This will split the coils by a 45deg angle. use a die grinder to cut through the unwanted coil, then fine tune the end loop. 5 minute job.
Great job sir. Impressed with your attention to detail. In your "design stage" did you have a look at Geo Thomas's book and his design of a retractable thread cutter. Not quite as elaborate or self actuating as yours but effective on the "pucker factor" none the less. Congratulations, Ron Wilken Canada
thank you for your comments. That’s not what I’m about, I enjoy doing this and would much prefer to help others (preferably the younger generation) achieve the same satisfaction of achievement. regards

What a beautiful tool, I hope I get around making one like it. Thank you for sharing.
Hi, go to www.thesheddweller.com for the sketch
@@Thesheddweller thank you, I was checking out your site this morning. What make is your surface grinder. I like how it was made for coolant, I wish mine had been built that way. I use a mist system, it works ok.
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.
Loved it, the process of making it even more. Congrats!
Hi, thanks for watching, glad you enjoyed.
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.
see FAQ’s WWW.thesheddweller.com
Outstanding design. Thanks for sharing!
Scott
Hi Scott, thank you for your comments much appreciated. Regards
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 ;)
Hi thanks for watching.
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.
Hi, Thank you, thanks for watching, cheers
brilliant idea...... you have steady rod set at head stock to activate the retract lever but at the same time it is also necessary to disangage slide attached to lead screw
Hi, thanks for your comments. yes the Half nuts are opened manually as soon as the cutter retracts. Regards
Wow! A fantastic prototype! Best be applying for a patent.
Thanks for sharing your knowledge with us.
Cheers
I’m afraid that has probably gone to Srilanka, they have asked a lot of questions about the thread cutter.
Love the ingenuity. Never seen anything like that. Personally though, I just flip the cutter upside down, run the chuck in reverse and then start the cut from the chuck moving toward the tailstock.
Hi, thanks for your comments. May I suggest you see the FAQ's at www.thesheddweller.com
Ah ok I understand now. Still great solution!
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
Hi, Thanks for your kind comments and thanks for watching.
Machine engineering is a great career but, as you will find out, it can be a bit like (real) police work,... in a word,.. repetitive, except that you are rewarded with an end result, something that will probably last for ever. enjoy.
PS. I'm just about to make another video for the two chucks, a modification.
A very intricate device indeed. Well done.
Hi, thanks for your kind comment.
Il y a quelques mois , j'ai découvert votre chaine . J'ai particulièrement apprécié la réalisation de ce porte outil rétractable pour les filetages . J'ai tout de suite entrepris la réalisation de ce dispositif en le modifiant pour le rendre plus compact . Les essais ne sont pas encore là . Dommage que votre blog soit fermé, je vous aurais bien envoyé quelques photos.
De toute manière, je tiens à vous féliciter pour le travail que vous réalisez et pour les connaissances que vous partagez.
Great gadget, it makes things quicker and also you get a finish on the thread that's unachievable normally
hi, that’s right.
Excellent travail monsieur .
Un grand salut de casablanca " Marocco"
Salut, merci d'avoir regardé, je suis désolé. Il a fallu beaucoup de temps pour répondre, j'ai manqué votre message.
Congratulations, this system is very enteresting.
Thank you for watching
Terrific piece of conceptual engineering. Absolutely spot on with your brilliant idea an execution.
Hi Don, thanks for your comments, I’m glad you enjoyed. Regards.
lovely little project now on my things to do list
I’ve put the sketch on my website www.thesheddweller.com
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!
Hi, Thanks for your kind comments
I missed most of the video, I was too busy contemplating involuntary bowl movements 😂😂
thanks for watching. :-D
Great engineering. I have never seen anything like this.
Hi, i always say, 'that there’s nothing new in machining’ and it's true, its just that some things aren’t aired very often. regards
Brilliant idea and excellent execution, congratulations man!
Hi Antoine, thanks for your comments. Regards.
Great job and machining tricks.
Well-done sir .👍
khan abdulrehman Hi, thanks for watching.
FYI: George H. Thomas designed a retractable tool for just this purpose-( I think Hemingway actually have a kit for people to make it) and as you may well know- Hardinge lathes come with the feature in built. Love your content.
I haven’t looked at the catalogue, I believe the Hemingway.co have all sorts of wonderful gadgets, some with very high price tags also.
The Hardinge & GHT solutions are not self retracting, so they reduce rather than eliminate the pucker.
Hi, thanks. Regards
Very well designed and machined! Nice work
Hi, thanks for your feedback.
That thing is genius. Great job
Tim Short hi, thank you for your comment.
"Pucker Factor" I like that saying. I am glad the American Machinist is not the only ones using that term. Cheers!
Hi, you’re welcome.
In my experience, spiral fluted taps are really only your friend in blind holes. Any through holes, I highly recommend standard straight flute, Japanese taps. Heavy weight oil on steel and stainless. Tap heavy is messy, but has proven itself superior to just tap magic. Clean up heavy is best done with some acetone, then some isopropyl, or that I had available.
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.
I always did when the guy next door threaded on the CNC. I’ve seen him run down the workshop a few times.
Beautiful great bit of kit as you would say
HI, Thanks for your comment. Absolutely… :-)
this is great work and craftmanship! thank you for sharing
Hi, thanks for your feedback, Regards
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
Hi lacaver64, Thank you for you kind comments,
regards
Is this what I'll be like when I'm older? Because I sure hope it will be. I can only admire the time and care taken. Time and opportunity in the shed has been sparse lately
Hi, thanks for your feedback. as far as YT is concerned I’m still learning, but you are right, shed time is a little restricted.
That is simply amazing! Fantastic design and execution! Subbed!
Thanks for your comment, Glad you enjoyed watching.
This is my first video of yours. Looking at your other videos, I see that (despite being on here for four years) you don’t have very many. Please tell me that is going to change. You, sir, are fantastic.
Hi, thanks for watching, I have also built half a house in that time. Despite this I’m only able to make a video, one every two to three months, due to other commitments.
@@Thesheddweller There’s a lot of great machining content on YT but a lot is American and while I have nothing against our transatlantic cousins, pronunciations of aluminium, lever etc along with US customary units drive me crazy. I wanted to find a UK-based channel (preferably the North of England) using the metric system so I could switch off that pedantic, critical part of my brain and focus more on the content. (I know, it’s practically a mental illness - right?) Finding this video was brilliant especially while stuck at home all the time! You really check so many boxes for what I’d want out of a creator. Suffice it to say that I’ll be glad for any projects you have to share and you can count on an eager audience of, at least, one for any future videos.
@@sambishop3211 Hi, Thanks. To some, I chatter too much, others say I don’t have enough content. I know I make mistakes, but mistakes are made on TV as well. Its always good to have someone that is perpared to bash the keys and show their appreciation. cheers.
This is very good working tools,
I try to make it, sir.
Hi, enjoy, have fun. regards
That is simply genius!!

Sir..... Marvelous engineering. I salute to your idea.
Hi, thank you for your comments, I'm glad you enjoyed the video.
Nice touch, now I wont a Surface grinder and small Shaper, but most seem to be on the east cost, I know there are some here In California but they are not parting with them.
Wonderful engineering. Thank you for the video
Thank you for your comments.
Wow, it´s a fantastic work. Thanks Sr.
Hi, thanks for watching.
Wow I like this. Might have to do one for myself.
Hi, I've put a sketch on my website www.thesheddweller.com
Ive been having really good results from running the threads backwards with the cutter upside down and running the lathe in reverse and starting the cut from the inside of the thread so once it makes it to the end of the cut its impossible to mess up. This is very interesting non the less. I like this idea for sure.
Hi, thanks for watching, please see FAQ’s at www.thesheddweller.com
Love the content so far.

Привет, спасибо за очень добрый комментарий. С уважением.
Very cool and genius design.
LOVED this idea!! Great work!!
Thanks, it's being copied all round the world, and I wouldn't be surprised if they are on sale from the "wish" shopping channel. cheers
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.
Thanks.. glad you enjoyed.
Great idea. Must say I've always gone for the quick wrist flick but then the bigger shoulders and shorter stick outs limit that at speed...or I give myself a root diameter groove to work to and make sure I'm ready to react!
Either way, your system trumps the lot and the ability to work at a speed that suits the tips as a CNC lathe would, is brilliant!
Congrats.
Hi Thomas Henderson, thank you for your comments. The tool will need a thread root groove for bigger threads or the insert will break.
@@Thesheddweller I saw you say that in another comment. I take it the spring-out is so sharp you practically end up with a dead stop at the end of the thread?
Job for the Mk2 version, cams out the thread depth in a single rotation and then jumps right out of the way. :-)
Cam out before snap back is worth investigating. I'll look in to it....... When I get a couple of spare minutes. Cheers:-)
@@Thesheddweller Keep me in the loop! :-)
Excellent work-thanks for sharing🤓👍
Hi, thank you thanks for watching.
Great design, and even a better job bringing it to life.
But I have one little trick to share with you. Shortening a tension spring and creating the loop is actually very simple. First determine how many coils you want to remove. use a Sharpie to mark the center between the two coils, the line up the mark on a 90 deg corner of a vise, and give it a quick rap with a steel hammer. This will split the coils by a 45deg angle. use a die grinder to cut through the unwanted coil, then fine tune the end loop. 5 minute job.
Great job sir. Impressed with your attention to detail. In your "design stage" did you have a look at Geo Thomas's book and his design of a retractable thread cutter. Not quite as elaborate or self actuating as yours but effective on the "pucker factor" none the less. Congratulations,
Ron Wilken
