Thanks Cliff! Heading over to Mark's channel now for part 1 of the build. I've been subscribed to him for a while and he does take on some interesting projects. I'm looking forward to learning more about this device.
I wondered if the main spindle was threaded but could figure the pitch adjustment with the simple nut slide. I guess I'll have to watch and see how you did it. As they say if anyone can, a kiwi can.
Gday Cliff, new subscriber here, I’ve followed Preso for quite some time now and after watching his latest episode and discovering your channel and thread express im following with great interest, I’ve never seen anything like this before and fascinated with how it works, I truly hope the plans become available at some time, great work mate, cheers
You might have some of the more technically challenging parts made in mass, and the other parts in drawing form sold as a kit. I could really see this used on a horizontal mill, or made with a larger hollow main shaft with a D1 taper.
Onya Cliff 👏👏👏👏👏 I KNEW that sooner or later you’d find a way through the ‘product development / marketing’ mire… And you’ve hooked up with the PERFECT collaborator 👍 Can’t wait to see this progress further. I always had the notion that you could get a Company to actually get this into production… but I realise just how problematic that would be 😵💫 But a ‘project’ that can still be spread to the engineering masses, via drawings/subscriptions/ whatever… as long as your IP is protected…. well that’s a winning outcome anyway. Congratulations to you and Mark 👏👏 Regards Robert 🇦🇺
I'm SO glad you finally decided to go this route. I know how apprehensive you were about it. It was the right decision. Wait till the momentum starts building, you're going to be blown away.
Hi Eitri. Yes well, I tried many times but couldn't directly reach the key businesspeople I wanted to, (with all the first contact filters that are nowadays in place), and I didn't want to take the design to the grave with me. That seemed such a waste of a really useful technology. Thanks for taking the time to give feedback and support. I hope you are correct. Cheers, Cliff
Just found your channel, I figure you have a yoke on the spindle and a threaded shaft which is rotated by the spindle. The yoke moves up the thread by a nut but pivots on the nut, The other end of the yoke arm is the thread pitch adjusting nut. which is the yoke arm pivot point. By moving the nut it changers the ratio between pivot point, the threaded shaft and the spindle, thus the yoke moves the spindle out at a different rate. This gives the different threads as the spindle rotates. good idea. You could also cut a four start thread with that probably, by lowing the cutter 1/4 of the pitch.
Hi Rosco. Interesting to read your design guess. I don't 100% follow your description, but today I will be publishing a closer look video, let me know if it fits with what you are visualizing. Cheers, Cliff
I came up with a similar idea of the design after seeing Cliff's videos that show the unit and I think yours is the basic concept if I follow your description. The spindle housing is mounted on vertical linear guides to the baseplate which is fixed to the mill table. The threaded main spindle has a nut captured by a yoke so that the nut transmits it's vertical motion to the baseplate thus moving the spindle housing vertically. The nut links it's motion to the baseplate via a simple variable ratio lever mechanism. The variable ratio lever has a pivot that is adjusted with the pitch adjusting nut that Cliff shows. Very clever and a nice design due to the simplicity! I would be interested in plans and if I ever had time to build one. I can see the main advantage of the thread milling to me would be the ability to get very good finish on difficult materials as well as threading to a shoulder. Looking forward to this project going forward. I would love to see plans available as well as a kit of some of the critical parts (maybe just the main spindle, nut, and bevel gear set would be needed for a basic kit).
@@stephaniestayton3156 Hi There. Oh, you guys are getting close now! Mark's build progress will force me to reveal all soon. Stephanie, thanks for your feedback and thoughts. I am interested in your design; wouldn't a changing ratio be generated by the lever as it swings over to the extremes? Cheers, Cliff
Patiently waiting for a link or a website, I’d happily pay for a copy of the plans or a kit. This is going to change everything for my little home shop/ business. Incredible design, I can’t wait to get one up and running. I’ve already watched marks video and waiting for the next video ! Congrats 🫡
Hi Jason. Yes, it has been a long wait. So hard to get traction in this new age of new contact filters. Thanks for the feedback and encouragement. Cliff
Also had the thought that this is the kind of tool that would have been sold by Ralmikes back in the manual days when you could find wonderful problem solving tools, before the walmartization of the industry by MSC, and the cnc takeover.
I love the idea, and I think this can easily be used on a lathe: cutting tool is in the spindle, and blank is mounted in your tool on the cross slide. setting it on center is a nice feature, and would enable proper depth readouts, but would also work off center...
I came here from Preso's site. I may never build one but the mechanism is cool as hell! Internal threads with a thread milling cutter would likely be my intended use if I built one.
Hi - It can cut internal threads if that is the oilway pattern you mean. V3 is formatted up to around 3mm and down to 0.4 mm pitch. But a special version could be made with much steeper pitches. Cheers, Cliff
Don't ever get discouraged with the development of the ThreadExpress. I am jealous of Mark Presling being able to make one. One question I have is " how long of threads can it produce?" It appears that may be a limiting factor, although long threaded parts can be produced by other means. Love your work, never stop !!!
Thanks for the encouragement and feedback! Re thread length. Remember ThreadExpress is for short to medium length threads. It does not suit long threads because it does not have a tailstock and center facility. For long threads you would still need for example a center lathe. I don't have the specs handy but with that no center design in mind, V3 is formatted to produce long enough threads for the different unsupported diameters. You can see from my videoed tests the samples are quite long. Its main advantage over a lathe is speed of set up, ease of machining and special pitches, of small to medium length threads. Cheers, Cliff
I've been looking for thread milling code to do npt threads on a CNC and assume that's how I got these videos recommended to me. I thought the concept was really neat, but didn't know how it worked until you pulled the cover off. It's an adjustable sine bar isn't it?
I saw Preso's video on this today so I came over to your channel to have a look, it's a very interesting piece of kit. It interests me because I use a homemade Mill and Lathe and at the moment I can't single-point threads, so I'm limited to just what I can make with them. I can see a Chinese manufacturer getting their hands on this, legitimately or not, and making them at some stage. I'm in the process of building a Webster Engine at the moment so I won't be in a position to attempt one of these until I finish that project. Liked and Subscribed. 👍
Been a subscriber to Mark for a long time. So glad the two of you have made this move. Excited to see the results & try one for myself. Thanks for this content! In my humble opinion, you should tell us how ti works sooner than later. You could sell all the parts up to a completely built unit & profit from all of it. The only reason that you don't have orders is because people don't understand the fundamental mechanism. Tell us that & orders will flow.
Cliff there was always a market for DIY for the Threadexpress. It was just a case of you coming to an understanding that this would be it's only market. Many people design some amazing things. But finding a manufacturer that would be interested is something else ?? It's good to see all your hard won't simply be wasted with a few people out there willing to at least build it as a project.
@ he he. Maybe modest in your opinion, but it’s the truth. My skills, I built up slowly, and it’s by trial and error. He he. Learning from you guys. I thank you.
I saw this on Mark Presling's channel, so headed over to yours. If it's not too late already, then I think you should patent the idea. Other people won't think twice about making a lot of money from your idea and hard work. Just my thoughts for what they're worth. Good luck with whatever direction you go in. I'm not a machinist, but it looks like a great invention to me.
Hi Mick. Thanks for your thoughts. I started to reply with specifics on my IP protection details, but on second thought, it is probably best not to discuss this subject publicly. But I appreciate your concern. Cheers, Cliff
Hi Cliff I have followed Mark for a while and came here from his first ThreadExpress build video. I am in NZ as well (Auckland). I find this a very interesting machine and can see the potential uses. Let me know if you need any assistance as I'm happy to provide any help if you need it. Regards Jon.
Hi Jon. A fellow youtuber in NZ! Good to meet you. Thanks for the feedback and your kind offer. Would you want to build a ThreadExpress, or did you have something else in mind. You can contact me through my Hallmark Design website if you want to email me. Cheers, Cliff
Hi Cliff I have watched all the video of the ThreadExpress and have great hopes that I will be able to purchase the plans when or if they become available. One question I have about the ThreadExpress is it able to produce both right and left hand threads in it present form? Thanks in advance! Ken Parsons Halifax N.S. Canada
I worked with a guy who was Machinist and he was doing steam turbine and gas turbine rebuild his power plant scale and the halves of the turbine,Housing if the threads were stripped out of the Housing, they were treadmill, large diameter threads so they can screw another big stud in there this is on the 2,3,4 inch thread size.
Ive head over here from Mark channel. I think this a simply fabulous mechanism. I will be building one if you make the plans available. Ive watched all the videos and studied all the pics but I dont yet know how it functions. im wracking my brain. May i ask 1 question? When you move the pitch adjustment nut does the scale compress or is it linear. Is the distance between say 1.5mm and 2mm the same as between 2mm and 2.5mm. It looks like it is on the vid.
Good to read the comments and questions of design enthusiasts. Stay tuned, I am picking the most likely outcome will be the design will soon be fully revealed. Re your question, you are on the right track to unravelling how it operates. Cheers, Cliff
@Threadexpress Thanks Cliff, I've been thinking about this non stop. I need to do a few sketches and a couple of calcs but I'm pretty sure I have a good idea of how it works. I have a mechanism in mind which would replicate the behaviour and would be packaged in a similar way.
Hi Cliff, I have difficulty with threading on my lathe for a number of reasons, but the primary one is I’m a tangle paw when trying to cut to a fixed point and backing the tool out as I disconnect the half nuts. Crashes galore ensue. My querie is would a lathe with a max spindle speed of 1400, which for most medium ish lathes is in the max speed range work with the threadexpress. I do not have a mill but belong to the school of thought that a lathe can pretty much do it all if you think about it. This is brilliant and if all it means for use on a lathe is lifting the top slide off and fitting an attachment, that is a very small inconvenience compared to the drama of single point cutting producing less than desirable results. Hang in there, you will be satisfied with Marks dedications to projects. Take care n play safe.
Hi. I think you are referring to using ThreadExpress on a lathe? Interesting, see the comment just above from @joergengeerds360 who also mentions this. Or are you thinking of making a thread milling cutter attachment to fit on your lathe topslide? I have done that and can confirm it works well. Cheers, Cliff
@ Thanks for replying Cliff, Yes, that was the gist of me comment. From the videos it appears that it would work, the only issues I perceived were getting the required speeds for using a carbide threading tool to cut the materials properly and aligning the threadexpress to the correct height and relief angles. Minor issues to some extent but if not possible could potentially be no better in quality than single point threading. Just trying to make sure the investment in time and materials would produce better results than the existing procedures and processes. Thanks for your time and I am looking forward to the reveals and Mark’s version of your dream. Regards.
interesting i found you through Marks chanel and will watch his seres on the build you have come up with a very good product i see others saying they need to know how it all works then they would buy one i say keep them guessing as if you release how it work then some one will clone it and claim it as there's there is only so much info you should release on this i am very surprised no one has picked up on this as in wonting to make them supose it needs more promotion to the right people keep up your work as it is very interesting even if you don't show much cheers From N Q Australia
Referred here by Mark Pressing’s channel. . . As a mechanical engineer I normally would hold back comments on mechanisms of which I can’t directly identify all the components but I am in agreement with some of the commenters that this application of a variable ratio drive is interesting. In my mind there are potentially two audiences - a number of them are hobbyists, the others being professionals. If the device is as promising as you think it is a hobbyist is more the candidate to purchase plans and build his own while the business owner would probably buy a finished unit with documentation, a warranty and support, etc. to be used in a commercial setting to expedite thread cutting. Additionally if the device is as promising as you believe, you have already engaged an IP/ patent professional while you work with other engineers to determine appropriate materials, manufacturing processes and costs for a commercially viable product. Looking forward to your lifting the tent flap.
K.i.s.s. applied I'd think of the following mechanism (with vertical mill in mind): Two screw axis, one horizontal Axis A, one vertical minus the helix angle Axis B. Axis B is geared to Axis A by a fixed ratio, say 4 to 1, assuming a gearing that allows for the helix angle deviation from being perpendicular. A chuck carriage C that slides over Axis B while rotating with Axis B, with Chuck attached. A driver carriage D that slides over a surface offset from horizontal with the helix angle ánd driven by a helper carriage H driven by Axis A. The Chuck rests in vertical direction on driver carriage D
While I haven't watched the entirety of Mark's first video, I saw enough to hear about the plan of producing engineering drawings for sale. My unsolicited advice: don't go this route. In a very short period of time, a Chinese company will acquire that information, then begin mass producing this, and you both will be hung out to dry in the sun. I have been in the field of parts manufacturing for 30 years and have never seen such a handy device. I think it's a great idea, although it will have a niche market. Best of luck to both you and Mark!
Hi! Thanks for your concern. I value your input and any response is welcome. I am hoping someone will contact us wanting the design first and to take over supply. (Hopefully we would still be able to supply drawings to enthusiasts). But if nobody does, as others have pointed out, years have gone by, and I should not take the design to the grave with me! I do not have the time to undertake the huge project of manufacturing or even assembling this myself. The long-term manufacture, admin, warranty, and support is for a much bigger outfit than I. I am also wary of selling drawings/plans. If the price is low enough to discourage copy sharing, the uptake numbers may become large, and I might feel somewhat obligated to provide support to a continually burgeoning demand. If the price is high enough to slow down demand, then this will encourage copy sharing. Currently, the only alternative I can see is basically to gift it to the world as a ''hobby labor of love''. I could apply a verification restriction over the supply of full plans requiring partial build photos before the final specs are supplied just to slow down the uptake and discourage speculation. I welcome viewers input here, there may be another approach I have yet to discover. I have found over the year's most engineering folk are genuine and honest and it gives my life meaning to find ways to contribute to them. Cheers, Cliff
Nice, you got a new sub here... Just seen my home-page and i opened Mark`s video, only to see yours as well just a few rows lower down, so i opened your vid too... As you can see - i`m here... I`ll definitely check Mark`s video out, but i wanted to check out the direct source first... Best regards! Steuss Edit - do keep in mind that a thread relief can actually strengthen the part... Having a thread end abruptly in solid material offers that segment as the stress focusing point, where a well machined thread relief allows the tool to disengage the cut and end the thread in a gulley, which while being a reduced diameter point of failure - is also no weaker than the threaded section itself, having essentially the same true diameter as the minimal diameter of the thread... Also, it is worth making custom tooling for regular threads that offers the true nose radius which clears even a store bought V-thread and fits perfectly with the identical custom thread that you make... Having nose radii at both the peak and the gulley of the thread allows both the nut and the rod to be stronger than a typical V-threaded piece of the same dimensions would be... Hell, it is an actual industry standard, but much less popular than the typical simple V or Acme/Trapez. thread due to the bother of radial features when compared to slant sides that meet at a sharp or a flat peak... You could say that the positive section of the thread offers a bit of strength that a relief has not - being a fully reduced diameter, but that is not really a source of strength of a threaded rod - the solid core is, with the threads merely being there to keep the damn thing fastened down to whatever load rating the core remains safely operational at...
Hi Steuss. Thanks for the feedback and encouragement. Thanks also for your follow up note. Yes, I am aware of and agree with your points. (I have not discussed them much in my videos so far, as many viewers want an overview and have limited time for long videos). Each thread design and machining plan should be considered relative to its application. Sometimes it is highly stressed and needs many refined details including the ones you mention. Other times the thread is not highly stressed, and ease of machining can be more of a priority. Cheers, Cliff
@@Threadexpress Ayy, anytime! It is a cool project and interesting work, as well as an interesting topic, so it drew my attention... Regarding the threads and specificities, sure, there is a reason why there are a few standard thread types and not just one... I just tend to develop fetishes over technically superb designs... Btw, speaking of superb designs, have you seen the ``planetary roller screw``? Look those up, essentially a leadscrew design akin to ball-screw regarding the nut design, but it is a regular thread profile(could use the rounded peak/gulley design)... I`ve been in love with that design ever since i saw it a few years ago... Best regards! Steuss
@@camillosteuss Thanks for that heads up. Yes fascinating. I am a hardware junky also! The video " Advantages of Roller Screws " gives a good overview. Cheers, Cliff
I have been watching Mark for some time and also have been following this channel for a bit. Definitely interested in product. Can I assume nothing is available until after Mark is completed his series? Has he estimated a length of time?
Hi there. Good the hear your enthusiasm. Yes, we should take it slowly. If we wait until this refined design build is completed, then it can be fully checked, and any adjustments needed applied to the design and drawings. Difficult to predict this type of timeframe, hopefully not long. Cheers, Cliff
Could this be laid sideways and attached to a lathe saddle, spin the cutter in the lathe chuck? I don't know if anyone has suggested this before. If made correctly it could double the potential market.
@@ernieremy4981 Hi! Yes, this has been suggested. I have been considering trialing this but there is a couple of issues I cannot see a simple fix to: Height adjustment and Helix angle adjustment. I suppose a special version, or a base attachment could be developed. Cheers, Cliff
question, please smallest pitch is 0.4mm on your design is it because of some design limits? or can a smaller brother of your machine be made for even smaller threads?
How do we, as budding UA-cam artists gain a chance? I know you are going for visibility and won't be slighted if i don't get an opportunity. Thank you this is an impressive project. Thank you. All the best. Respectfully Term
Thanks for your encouragement, it has been a real struggle to get it started. Hopefully now ThreadExpress will get a head of steam and get underway. Cheers, Cliff
ua-cam.com/video/6_1Nlf-X4bw/v-deo.html some things might be possible to do with a milling spindle on the lathe as well. Curious how your mechanism works :-) hoping Preso will be allowed to reveal it.
Hi, I've enjoyed your videos. I teach machine shop. I am interested in both the machine and the plans (would like to use our students to build one). Please contact me with the price for the machine, so I can make a proposal to my boss. Thank you,
Hi - Thanks for your feedback and your interest. See the first comment where I cover this subject. Send me an email if you want to discuss this further in specifics. You can reach me through the Hallmark Design website link, or through my email directly under ''about'' Cheers, Cliff
Yes, it is best suited to shops that don't have CNC, or for threads that need the cutter set at the helix angle. Or for CNC shops that don't want to tie up their VCM to cut a quick thread. Cheers, Cliff
There is an old axiom of marketing. A confused customer will not be a customer for long! Be very careful you are fitting this to the tee. What are you selling?
@@Threadexpress I am not being negative. And obviously you are a very talented designer and engineer. But I watched the video you talked about, just can't recall his name right now. And even after watching it, it still clear what the device is for and even less how it works. I am very sure you have an outstanding accessory but it would be better to explain the machine or show the workings. That is if you can without disclosing your secrets. It seemed like the other man was also concealing some of the workings. And that is just fine too if you are planning on selling the drawings or the device. I will go back and watch the video again, possibly is misses something. Thanks for your reply, you did make a good video on it. Thank you.
@@glennfelpel9785 Do you know how the insides of your PC transmit Data and why did that not stop you buying it? It doesn't mean those of us with a mechanical bent just 'want to know' how it works but sometimes seeing the Outside of a Box and the Results of what it can do are 'plenty' of marketing. If you are seeking to maintain some IP control to possibly sell a design and invention removing the covers is not how you do that.
Can you please explain your intentions wrt to your invention? Are you in the process of obtaining a patent and that is why you don’t want to reveal the operating principle? Are you hoping for a “fairy godfather” to see this on YT and fund the patent application? Are you planning to sell a few plans and possibly kits on Etsy and use YT as market research? I started watching your videos with some interest but you are loosing me with this seemingly endless teasing. If you at least explained the purpose of it all it would be helpful. Thx

It interests me because I use a homemade Mill and Lathe and at the moment I can't single-point threads, so I'm limited to just what I can make with them. I can see a Chinese manufacturer getting their hands on this, legitimately or not, and making them at some stage. I'm in the process of building a Webster Engine at the moment so I won't be in a position to attempt one of these until I finish that project. Liked and Subscribed. 👍
Good to meet a fellow engineering youtuber ! Subscribed and thanks for the feedback. Cheers, Cliff
Been a subscriber to Mark for a long time. So glad the two of you have made this move. Excited to see the results & try one for myself. Thanks for this content! In my humble opinion, you should tell us how ti works sooner than later. You could sell all the parts up to a completely built unit & profit from all of it. The only reason that you don't have orders is because people don't understand the fundamental mechanism. Tell us that & orders will flow.
Thanks for your thoughts, Cliff
Cliff there was always a market for DIY for the Threadexpress.
It was just a case of you coming to an understanding that this would be it's only market.
Many people design some amazing things.
But finding a manufacturer that would be interested is something else ??
It's good to see all your hard won't simply be wasted with a few people out there willing to at least build it as a project.
Hi fellow youtuber. Thanks for your feedback, your patience and remaining positive!
Cheers, Cliff
Cliff, this is so very exciting. I’ve watched every video Preso has created and I’m really looking forward to the series. 👍😎👍
Hi there. Thanks for the encouragement and feedback. Cheers, Cliff
Great video. I’m definitely not on either of your experience levels, but definitely interested. One day I’ll get there. Great work and design. Thanks
Hello modest fellow youtuber from the UK. Thanks for the feedback and encouragement! Cheers, Cliff
@ he he. Maybe modest in your opinion, but it’s the truth. My skills, I built up slowly, and it’s by trial and error. He he. Learning from you guys.
I thank you.
Looking forward to more details. I don't think it will be a plug and play for my mill (PM-833tv) but it looks like I will learn a bit along the way.
Yeah, sounds like you watched my previous video Pros and Cons. Cheers, Cliff
I saw this on Mark Presling's channel, so headed over to yours. If it's not too late already, then I think you should patent the idea. Other people won't think twice about making a lot of money from your idea and hard work. Just my thoughts for what they're worth. Good luck with whatever direction you go in. I'm not a machinist, but it looks like a great invention to me.
Hi Mick. Thanks for your thoughts. I started to reply with specifics on my IP protection details, but on second thought, it is probably best not to discuss this subject publicly. But I appreciate your concern. Cheers, Cliff
Hi Cliff I have followed Mark for a while and came here from his first ThreadExpress build video. I am in NZ as well (Auckland). I find this a very interesting machine and can see the potential uses. Let me know if you need any assistance as I'm happy to provide any help if you need it. Regards Jon.
Hi Jon. A fellow youtuber in NZ! Good to meet you. Thanks for the feedback and your kind offer. Would you want to build a ThreadExpress, or did you have something else in mind. You can contact me through my Hallmark Design website if you want to email me. Cheers, Cliff
Hi Cliff
I have watched all the video of the ThreadExpress and have great hopes that I will be able to purchase the plans when or if they become available.
One question I have about the ThreadExpress is it able to produce both right and left hand threads in it present form?
Thanks in advance!
Ken Parsons Halifax N.S. Canada
Hi Ken. Thanks for your feedback. ThreadExpress V3 can only produce right hand threads. Cheers, Cliff
I worked with a guy who was Machinist and he was doing steam turbine and gas turbine rebuild his power plant scale and the halves of the turbine,Housing if the threads were stripped out of the Housing, they were treadmill, large diameter threads so they can screw another big stud in there this is on the 2,3,4 inch thread size.
Interesting, yes threadmilling is a process that is not commonly understood. Cheers, Cliff
that thing is awesome
Thanks for the feedback! Cliff
Ive head over here from Mark channel. I think this a simply fabulous mechanism. I will be building one if you make the plans available. Ive watched all the videos and studied all the pics but I dont yet know how it functions. im wracking my brain. May i ask 1 question? When you move the pitch adjustment nut does the scale compress or is it linear. Is the distance between say 1.5mm and 2mm the same as between 2mm and 2.5mm. It looks like it is on the vid.
Good to read the comments and questions of design enthusiasts. Stay tuned, I am picking the most likely outcome will be the design will soon be fully revealed. Re your question, you are on the right track to unravelling how it operates. Cheers, Cliff
@Threadexpress Thanks Cliff, I've been thinking about this non stop. I need to do a few sketches and a couple of calcs but I'm pretty sure I have a good idea of how it works. I have a mechanism in mind which would replicate the behaviour and would be packaged in a similar way.
I have to add that it is both extremely clever and extremely simple at the same time. Bravo 👏
@@liammccaffrey355 Yours might turn out to be a different but superior design! Cliff
@@liammccaffrey355 Cheers! Cliff
Hi Cliff,
I have difficulty with threading on my lathe for a number of reasons, but the primary one is I’m a tangle paw when trying to cut to a fixed point and backing the tool out as I disconnect the half nuts.
Crashes galore ensue.
My querie is would a lathe with a max spindle speed of 1400, which for most medium ish lathes is in the max speed range work with the threadexpress.
I do not have a mill but belong to the school of thought that a lathe can pretty much do it all if you think about it.
This is brilliant and if all it means for use on a lathe is lifting the top slide off and fitting an attachment, that is a very small inconvenience compared to the drama of single point cutting producing less than desirable results.
Hang in there, you will be satisfied with Marks dedications to projects.
Take care n play safe.
Hi. I think you are referring to using ThreadExpress on a lathe? Interesting, see the comment just above from @joergengeerds360 who also mentions this. Or are you thinking of making a thread milling cutter attachment to fit on your lathe topslide? I have done that and can confirm it works well. Cheers, Cliff
@ Thanks for replying Cliff,
Yes, that was the gist of me comment.
From the videos it appears that it would work, the only issues I perceived were getting the required speeds for using a carbide threading tool to cut the materials properly and aligning the threadexpress to the correct height and relief angles.
Minor issues to some extent but if not possible could potentially be no better in quality than single point threading.
Just trying to make sure the investment in time and materials would produce better results than the existing procedures and processes.
Thanks for your time and I am looking forward to the reveals and Mark’s version of your dream.
Regards.
@@pebrede OK Thanks. Cliff
Want one, Happy to pay for plans when they become available.
Thanks for that feedback. Stay tuned, Cliff
interesting i found you through Marks chanel and will watch his seres on the build you have come up with a very good product i see others saying they need to know how it all works then they would buy one i say keep them guessing as if you release how it work then some one will clone it and claim it as there's there is only so much info you should release on this
i am very surprised no one has picked up on this as in wonting to make them supose it needs more promotion to the right people keep up your work as it is very interesting even if you don't show much
cheers From N Q Australia
Cheers! I appreciate you reading the comments and giving your sensible thoughts, (and envy your climate, it's still cold down here). Cliff
Referred here by Mark Pressing’s channel. . . As a mechanical engineer I normally would hold back comments on mechanisms of which I can’t directly identify all the components but I am in agreement with some of the commenters that this application of a variable ratio drive is interesting. In my mind there are potentially two audiences - a number of them are hobbyists, the others being professionals. If the device is as promising as you think it is a hobbyist is more the candidate to purchase plans and build his own while the business owner would probably buy a finished unit with documentation, a warranty and support, etc. to be used in a commercial setting to expedite thread cutting. Additionally if the device is as promising as you believe, you have already engaged an IP/ patent professional while you work with other engineers to determine appropriate materials, manufacturing processes and costs for a commercially viable product. Looking forward to your lifting the tent flap.
Thanks for taking the time to share your thoughts here. I hear where you are coming from. Cheers, Cliff
K.i.s.s. applied I'd think of the following mechanism (with vertical mill in mind):
Two screw axis, one horizontal Axis A, one vertical minus the helix angle Axis B.
Axis B is geared to Axis A by a fixed ratio, say 4 to 1, assuming a gearing that allows for the helix angle deviation from being perpendicular.
A chuck carriage C that slides over Axis B while rotating with Axis B, with Chuck attached.
A driver carriage D that slides over a surface offset from horizontal with the helix angle ánd driven by a helper carriage H driven by Axis A.
The Chuck rests in vertical direction on driver carriage D
For sizing of the machinery you might have had to add a lever to push up the chuck
Stay tuned and see if you are correct! Cheers, Cliff
Thread milling for a manual machine.....what a good idea
Cheers! Cliff
While I haven't watched the entirety of Mark's first video, I saw enough to hear about the plan of producing engineering drawings for sale. My unsolicited advice: don't go this route. In a very short period of time, a Chinese company will acquire that information, then begin mass producing this, and you both will be hung out to dry in the sun.
I have been in the field of parts manufacturing for 30 years and have never seen such a handy device. I think it's a great idea, although it will have a niche market.
Best of luck to both you and Mark!
Hi! Thanks for your concern. I value your input and any response is welcome.
I am hoping someone will contact us wanting the design first and to take over supply. (Hopefully we would still be able to supply drawings to enthusiasts). But if nobody does, as others have pointed out, years have gone by, and I should not take the design to the grave with me! I do not have the time to undertake the huge project of manufacturing or even assembling this myself. The long-term manufacture, admin, warranty, and support is for a much bigger outfit than I.
I am also wary of selling drawings/plans. If the price is low enough to discourage copy sharing, the uptake numbers may become large, and I might feel somewhat obligated to provide support to a continually burgeoning demand. If the price is high enough to slow down demand, then this will encourage copy sharing.
Currently, the only alternative I can see is basically to gift it to the world as a ''hobby labor of love''. I could apply a verification restriction over the supply of full plans requiring partial build photos before the final specs are supplied just to slow down the uptake and discourage speculation.
I welcome viewers input here, there may be another approach I have yet to discover.
I have found over the year's most engineering folk are genuine and honest and it gives my life meaning to find ways to contribute to them.
Cheers, Cliff
Nice, you got a new sub here... Just seen my home-page and i opened Mark`s video, only to see yours as well just a few rows lower down, so i opened your vid too... As you can see - i`m here... I`ll definitely check Mark`s video out, but i wanted to check out the direct source first...
Best regards!

Edit - do keep in mind that a thread relief can actually strengthen the part... Having a thread end abruptly in solid material offers that segment as the stress focusing point, where a well machined thread relief allows the tool to disengage the cut and end the thread in a gulley, which while being a reduced diameter point of failure - is also no weaker than the threaded section itself, having essentially the same true diameter as the minimal diameter of the thread... Also, it is worth making custom tooling for regular threads that offers the true nose radius which clears even a store bought V-thread and fits perfectly with the identical custom thread that you make... Having nose radii at both the peak and the gulley of the thread allows both the nut and the rod to be stronger than a typical V-threaded piece of the same dimensions would be... Hell, it is an actual industry standard, but much less popular than the typical simple V or Acme/Trapez. thread due to the bother of radial features when compared to slant sides that meet at a sharp or a flat peak... You could say that the positive section of the thread offers a bit of strength that a relief has not - being a fully reduced diameter, but that is not really a source of strength of a threaded rod - the solid core is, with the threads merely being there to keep the damn thing fastened down to whatever load rating the core remains safely operational at...
Hi Steuss. Thanks for the feedback and encouragement. Thanks also for your follow up note. Yes, I am aware of and agree with your points. (I have not discussed them much in my videos so far, as many viewers want an overview and have limited time for long videos).
Each thread design and machining plan should be considered relative to its application. Sometimes it is highly stressed and needs many refined details including the ones you mention. Other times the thread is not highly stressed, and ease of machining can be more of a priority. Cheers, Cliff
@@Threadexpress Ayy, anytime! It is a cool project and interesting work, as well as an interesting topic, so it drew my attention...
Regarding the threads and specificities, sure, there is a reason why there are a few standard thread types and not just one... I just tend to develop fetishes over technically superb designs... Btw, speaking of superb designs, have you seen the ``planetary roller screw``? Look those up, essentially a leadscrew design akin to ball-screw regarding the nut design, but it is a regular thread profile(could use the rounded peak/gulley design)... I`ve been in love with that design ever since i saw it a few years ago...
Best regards!
Steuss
@@camillosteuss Thanks for that heads up. Yes fascinating. I am a hardware junky also! The video " Advantages of Roller Screws " gives a good overview. Cheers, Cliff
Happy to pay for a set of plans
Thanks for that feedback. Stay tuned. Cheers, Cliff
I have been watching Mark for some time and also have been following this channel for a bit. Definitely interested in product. Can I assume nothing is available until after Mark is completed his series? Has he estimated a length of time?
Hi there. Good the hear your enthusiasm. Yes, we should take it slowly. If we wait until this refined design build is completed, then it can be fully checked, and any adjustments needed applied to the design and drawings. Difficult to predict this type of timeframe, hopefully not long. Cheers, Cliff
Could this be laid sideways and attached to a lathe saddle, spin the cutter in the lathe chuck? I don't know if anyone has suggested this before. If made correctly it could double the potential market.
@@ernieremy4981 Hi! Yes, this has been suggested. I have been considering trialing this but there is a couple of issues I cannot see a simple fix to: Height adjustment and Helix angle adjustment. I suppose a special version, or a base attachment could be developed. Cheers, Cliff
Variable speed transmission that drive spindle in and out
12:46
Hopefully soon you will see if you are correct. Cheers, Cliff
question, please
smallest pitch is 0.4mm on your design
is it because of some design limits?
or can a smaller brother of your machine be made for even smaller threads?
Hi. Yes, a smaller brother can be made. V3 is formatted to include the range of common workshop threads. Cliff
@Threadexpress thank you 👍
shall follow Prezza building it to see if it is a project for me
keep up the good work.
Thanks for taking the time to give encouragement. Cliff
Hi, sent you an email with a (very) rough sketch of how I think it works inside. Love to hear what you think.
Thanks. I replied via the email. Cliff

ua-cam.com/video/6_1Nlf-X4bw/v-deo.html some things might be possible to do with a milling spindle on the lathe as well.
Curious how your mechanism works :-) hoping Preso will be allowed to reveal it.
I am picking that will be the most likely outcome. Cheers, Cliff
Hi,
I've enjoyed your videos. I teach machine shop. I am interested in both the machine and the plans (would like to use our students to build one). Please contact me with the price for the machine, so I can make a proposal to my boss.
Thank you,

Great mechanism but any CNC Machine can easily and cheaply replace it. Keep up the good work!
Yes, it is best suited to shops that don't have CNC, or for threads that need the cutter set at the helix angle. Or for CNC shops that don't want to tie up their VCM to cut a quick thread. Cheers, Cliff
There are things that will never be replaced by CNC.
@@evognayr I have CNC and use it for thread milling some jobs. Other jobs better suit ThreadExpress. It depends on the type of work. Cheers, Cliff
There is an old axiom of marketing. A confused customer will not be a customer for long! Be very careful you are fitting this to the tee. What are you selling?
Hi - I do not fully understand, please elaborate. Regards, Cliff
@@Threadexpress I am not being negative. And obviously you are a very talented designer and engineer. But I watched the video you talked about, just can't recall his name right now. And even after watching it, it still clear what the device is for and even less how it works. I am very sure you have an outstanding accessory but it would be better to explain the machine or show the workings. That is if you can without disclosing your secrets. It seemed like the other man was also concealing some of the workings. And that is just fine too if you are planning on selling the drawings or the device. I will go back and watch the video again, possibly is misses something.
Thanks for your reply, you did make a good video on it. Thank you.
@@glennfelpel9785 Do you know how the insides of your PC transmit Data and why did that not stop you buying it? It doesn't mean those of us with a mechanical bent just 'want to know' how it works but sometimes seeing the Outside of a Box and the Results of what it can do are 'plenty' of marketing. If you are seeking to maintain some IP control to possibly sell a design and invention removing the covers is not how you do that.
@@glennfelpel9785 Thanks for your thoughts and feedback. Cliff
Can you please explain your intentions wrt to your invention?
Are you in the process of obtaining a patent and that is why you don’t want to reveal the operating principle?
Are you hoping for a “fairy godfather” to see this on YT and fund the patent application?
Are you planning to sell a few plans and possibly kits on Etsy and use YT as market research?
I started watching your videos with some interest but you are loosing me with this seemingly endless teasing. If you at least explained the purpose of it all it would be helpful.
Thx
