ThreadExpress 2.2 - Further Revelation

[@Threadexpress]

After publishing I noticed right at the end a spy peering through the window! 😎Yikes...☹

[@georgedreisch2662]

Saw that too. My first thought was the old, “Kilroy was here” graffiti…

[@Threadexpress]

@@georgedreisch2662 Yes! My Dad used to draw those! Cliff

[@pobox1641]

Some people will go to any length to steel your secret! LOL

[@Threadexpress]

@pobox1641 I know!

[@Preso58]

I like the idea of having options when it comes to cutting threads. In a lot of cases, thread milling would be preferable. My only issue is the physical size of the Thread Express. You would need a Bridgeport or similar sized knee mill to make it work. That probably puts it out of the reach of most hobbyists. I am hoping the mechanism could be refined or scaleable to make it lighter and more compact. Can't wait for the final reveal. It's like the dance of the seven veils!

[@Threadexpress]

Thanks for your support! Cheers, Cliff

[@Threadexpress]

Yes, a scaled down version, with a finer small thread range to suit, could be designed. Maybe a 'half size'' Cliff

[@accuracymark]

would be an excellent machine for vertical chambering and threading rifle barrels

[@stephenbergman3875]

Cliff, I think you have a very unique product. The ability to set all different pitches with no additional tooling is brillant. I say this as a machinist with 45 years experience and over 20 in aerospace. Everything you've said regarding thread pitch and form is 100% SPOT ON. Setting the axis of cutter rotation perpendicular to the thread lead angle is necessary to cut highly accurate thread form. I have setup thread milling attachments on vertical milling machines that used a ground precision lead to run the rotating base up or down. This required a different master lead for every different pitch. This is one area where your machine really shines! Additionally it appears that the pitch may be infinitely adjustable, providing an easy way to produce proprietary and unique threads. I'm anxious to see how your mechanisms works! Regards, Stephen, Idaho USA

[@Threadexpress]

Hi Stephen. Thanks for your experienced points, feedback and encouragement! Most appreciated

[@stevengehm1287]

I say PRESS ON! When the light bulb goes on in the rest of the world, You were already there, and guess what.. Here it is available. I guess folks who like building from a kit might purchase one, but the Production capabilities are where this guy will prove worthwhile. I dig it.

[@Threadexpress]

That was encouraging! Cheers! Cliff

[@arcanearmouryprops]

Just seeing this and its fascinating, and the results it produces are wonderful. My guess on your pitch generation is that you have an adjustable angled ramp/guide that, effectively acts as a divisor ?... I'm going to see if you published another video now to see if I'm close with my guess!

[@Threadexpress]

Thanks for your feedback! Cheers, Cliff

[@allenbrown7820]

I believe you should continue on. I like the idea you can cut flats and scallops also. Waiting on the next video to see when you take the lid off and let the smoke out of the box! Be Safe!

[@Threadexpress]

Thanks for your feedback Allen. Cliff

[@AndrewClarke-wb5hh]

That's a terrific invention. I'd seen the earlier videos but this one is new to me. I didn't appreciate how small and compact the device is. I think it will be widely accepted by home-shop machinists, small maintenance shops, and maybe even commercial machine shops. But few home shops or small maintenance shops have a big Bridgeport mill. I think you should demo it on a smaller Chinese round-column mill with perhaps 8" reach. Many home shops don't have any sort of mill and their lathes lack threading capabilities. A smaller version that would bolt on a lathe cross slide should be popular. To protect your intellectual property, I'd suggest copywriting the drawings and selling them for $50 a set. If I could build one with less than $200 in bought-in parts, I'd buy a set of drawings. Best of luck commercializing this. There are lots of us out here looking forward to the reveal and a look inside the box. As for guesses as to how it works, I think you have the spindle supported by a variable-pitch nut - similar to a variable-pitch propeller or the variable stator blades on the compressor end of a gas turbine. Three narrow "blades" in the nut should provide sufficient spindle support. The spindle would have a malleable outer sleeve that the blades in the variable-pitch nut could cut into - Delrin or similar. As the spindle rotates it would back out of the nut at a rate determined by the pre-set blade pitch or helix angle. There are likely better (more durable) materials for the spindle sleeve than Delrin - perhaps some self-healing "carpet" with little microscopic radial fibres that would be deflected by the blades to form a temporary thread in the sleeve, but still support the weight of the spindle, chuck, and work. A return spring may be necessary for horizontal operation. The helix angle is determined by the thread pitch and diameter. For a 1-1/2" diameter sleeve, a 64 tpi thread would have a helix angle of 0.1900 degrees. A 9 tpi thread would have a helix angle of 1.3507 degrees. The blades wouldn't need swivels. They could be spring loaded to the shallow 64 tpi angle and deflected upwards by a circular cam ring with three ramps to angle the three blades up. With three blades, 100 degrees of cam rotation would shift/twist the blades from 64 tpi to 9 tpi. To minimize costs, avoid castings. The dovetail slide and spindle supports could use 1/2" aluminum plate and SHCSs. A foot of 1" sch 80 pipe would work for the spindle. The end could be threaded to accept the user's existing chucks. The variable-pitch nut could use X-Acto knife blades or broken hacksaw blades. Your bevel gears could be replaced with aluminum jockey pulleys and a round O-ring belt.

[@Threadexpress]

Hi Andrew. Thanks for your thoughts and feedback. You have an interesting design idea, and interesting marketing points, duly noted. Stay tuned, hopefully the big reveal will be soon. Cheers, Cliff

[@jasonarnold7578]

Hi Cliff, just on the thread cutting on a lathe, Joe Pie (KZbin) had a great solution with the single point held upside down and the lathe run in reverse. Also, a die head with chasers makes an awesome thread and doesn't require a relief trench in the part. I think your thread express is a great idea for people that don't have a CNC mill or even people that have a manual mill but don't have a lathe. The real question should be cost. Cheers, Jason.

[@Threadexpress]

Thanks for your thoughts. Usually cost depends on production quantity, which depends on demand, which depends on price...and so we go around and around. Cheers, Cliff

[@Threadexpress]

I have tried reverse thread cutting... have you tried it? It is useful in some situations but has its challenges too. You need an undercut to set the tool into each time and unless it is wide, it is difficult to stop the lathe in the exact position that lets the tool clear the work, a chipped tool is often the outcome. Also, you cannot see the cutting action as it is underneath, you often need to see when you are machining challenging materials and threads. Cliff

[@Jimbo-t2h]

Hi Cliff. Am very intrigued and can’t wait to the reveal. I think the accuracy compared to other methods is awesome. You are of the Rob Renzetti and Stefan Gotteswinter class of talent.

[@Threadexpress]

Thanks for your kind words and feedback. Cheers, Cliff

[@johnthebikeguy]

As someone who machines original things, I totally get the frustration of no demand. Your design is definitely an improvement over dies. I almost never use dies unless it’s not very important. I have no idea about how it works, but I feel confident that you’ve done a good job at it. I’ve thought about using a rotary cutter on the lathe, but never tried.

[@Threadexpress]

Thanks for your empathy and support. Cheers, Cliff

[@KenToonz]

Cliff, your ingenuity and craftsmanship always fascinate me and I have no doubt this invention is superior to other methods. I believe the issue is that one would need to generate a lot of screws to justify the cost and that someone who makes lots of screws already has a method that is faster. That method may not be as accurate, but it's sufficient for their application.

[@Threadexpress]

Thanks for your thoughts, you make a good point. Cheers, Cliff

[@AndrewClarke-wb5hh]

There are many home-shop machinists who enjoy the challenge of building fixtures and attachments to extend the capabilities of their existing lathes, milling machines, etc. Their budgets are limited but they have over-flowing scrap boxes and plenty of time. They will buy your plans if the cash outlay for purchased parts is modest. I had a look at Mark Presling's build video and think he's making a first-class commercial tool, but making it too expensive for home-shop machinists. Some suggestions - avoid castings or weldments (use bolt-together aluminum plates), avoid purchased ball bearings (use Oilite or brass bushings), avoid purchased shafting and buying the long drill for the central hole (use heavy-wall pipe), avoid purchased bevel gears (use the bevel gears from a charity-shop hand drill). Your device will be a necessity in every home shop if the cost is minimal. Consider two versions - 1st-class commercial, and home-shop good enough.

[@Threadexpress]

Hi Andrew. Thanks for your thoughts. Cheers, Cliff

[@georgedreisch2662]

You’ve got my attention. Preliminary imagining here. I’m imagining, with a adequate pass through diameter, and provision for a spider or a outboard mounted 4-jaw chuck, for alignment and support, finding use to mill threads on firearm barrel breaches and muzzles.

[@Threadexpress]

Thanks for your thoughts, I keep forgetting to show the pass through. Cheers, Cliff

[@markh253]

I like it. I can see a lot of possibilities with this machine.

[@Threadexpress]

Thanks for the feedback! Cliff

[@zacharyv3407]

Very cool…I need to check out the rest of ur vids

[@Threadexpress]

Cheers! Cliff

[@kevinmullen4352]

You are right thread milling causes quadrant errors as back lash from the reversal of the ball screws does generate a lobe effect. We had a precision thread grinder and you need to set the helix angle

[@Threadexpress]

Thanks for your feedback. Cliff

[@LeonardRoberts]

This looks like a wonderful tool to have, very versatile, also like being able to do multiple processes in one setup. As a true beginner (60 y/o dipping his toe in the water) just getting started with my first Lathe and have only a drill press no Milling machine (yet), I vote continue on, by the time my skills and wallet could afford this it will be a reasonable price ;-).

[@gertjevanpoppel7270]

It is a beautiful piece of work 👍😀. And i love making threads on my lathe and take pride in making a beautiful thread. I can see the benefits of this machine and the quality of threads it's capable of making. The question you ask yourself in the video is if there is a use for a production version of this machine in today's industry. And i think you should ask yourself how many shops produce high quality threads around the world and how are they doing it now. And can this small percentage off shops see the benefit from your machine. Nobody with any related knowledge to accurate machining of threads doubts the capability of your machine. But the question is does it bring any benefits for them if they change from their current methods to your machine and how many of these shops are willing to do so. The only way to get the answer is for you to go actively to these shops and show them what you got . Also ( I don't know the exact English word) you should get your machine on these kinds of conventions where manufacturers come together and show their new machines for the industry. In my opinion there is a future for your machine , but it will be a small specialized market. Companies that produce accurate machines with accurate parts and threads would surely see the benefits of using your machines in my opinion. But it will take the necessary work and effort from you to get your machine noticed in this part of the industry 😀. Please keep making this great content and videos and share your ideas with us 👍😀 Sad to see people making comments that don't have any idea about making accurate threads and the basic concepts behind thread cutting.

[@Threadexpress]

Hi! Thanks, you for your encouragement and kind words. Also, for your thoughts. It is not just high-quality threads, but speed and ease of production. One thing I forgot to mention, is that with a lathe, if the leadscrew is exposed, it should be cleaned each time before use, so hard chips are not jammed in the half nuts. Best regards, Cliff

[@allenwoodruff9341]

Discovered your channel this morning. You have a very interesting machine. For most of the machining done in this world tolerances of plus or minus. 005" to .003" is fine. Thus, the errors of CNC interpolation are not a problem. Once you start trying to hold tolerances of .001" and better the inaccuracies become far more problematic. This is doubly true when you start working with smaller parts. I have spent a lifetime building niche industrial machinery and can tell you that you do not need to build large numbers of machines to have a viable business. The world is a big place and once you start selling a machine people start finding uses for it that you never thought of. I would encourage you to continue your work. Let me know if you start selling plans I would love to build one and see what I could do with it.

[@Threadexpress]

Thanks for your thoughts and feedback. Most appreciated. Cliff

[@VoidedWarranty]

Interpolation errors of .003 or even .001" is extremely high! mine has a maximum position error in aln axes of .00011, its much better if you only measure in 2 axes

[@keithupson5495]

That's a mint piece of kit. We dont have a great need to machine a lot of threads. But this definitely has its place for sure. I am very interested in your pitch generator design. Well done. As you say, a lot of good ideas are well overlooked or dismissed, Lots of ways of doing things. Tradesmen are few and far between these days. Some strive and aspire for excellence. Some simply don't care. And would except anything. Be very proud of yourself. You have Nailed it.

[@Threadexpress]

Thanks for your kind words and encouragement! Cheers, Cliff

[@robertmccann7570]

Personal opinion it does have value 1 in reduction of shop today ls needed in a job shop, 2 one tool to replace time and tools needed to be purchased to compete a special or specific job, 3 if device is durable enough would be a one time cost for years of use, 4 it also replaced some non thread related tooling another reduction in overall tooling, the downside for some maybe the working and understanding of the operation of the tool, also a lot of individuals I know might fail to understand the complexity of this tool. I can picture in my head the way it operates which gives me pause on the overall durability and reliability overtime. Also the different mounting capability for rigidity and position. I am enjoying the overall videos but not the implied suspense. I think if you were able to box the necessary materials and plans and directions into package you would most likely be able to sell some of these items. This would also promote through word of mouth and show and tell.

[@pierrec1590]

Your challenge is to identify the market and reach it effectively. It is far from trivial. One way to achieve this is to show people various things that can be done with your invention that are difficult or even impossible. In general people do not have much imagination: you have to explain and describe again and again. One example that comes to mind is the pantorouter first developed by Mathias Wandel. He made a number of videos showing how to use it.

[@Threadexpress]

Thanks for your thoughts, it is a challenge. I have been thinking of examples and content. Cheers, Cliff

[@lohikarhu734]

BTW, if there are some complex interactions that are done mechanically, perhaps you can find a 'partner' to use some electronic/electromechanical means of cutting parts count or complexity, without sacrificinng *significant* accuracy ... for instance, it's quite easym today, to get encoders from 600-1000 counts per revolution, and stepper motors with thousands ofnsteps per revolution ... it's just a thought.

[@lohikarhu734]

Saw your comments about electronics ...sure enough, one has to have spindle, good bearings, rigidity, before getting to the actual controls!

[@Threadexpress]

Thanks for your input here. Cliff

[@belair_boy6035]

Personally as a maker and model engineer, I might be interested in building a version of it once I knew how it worked and what was involved but as I can currently cut threads by several methods, I would not buy a finished product. Looking forward to the final reveal. Cheers, Andrew

[@Threadexpress]

Thanks for the feedback Andrew, Cheers, Cliff

[@quintonmorgan8112]

Hey Cliff, I think your invention is very interesting. I can’t wait to see how it works and I was very intrigued when I first saw it on your last video and been eagerly waiting for the next update. I would be interested in building it or buying one from you. I would like to see how it performs when mounted on my makino c-40 tool and cutter grinder. I’ve experimented with thread grinding on it by using lead screw masters mounted on the head stock and using a finger the make the table move as you rotate the head stock so you can thread on it. And I used a radius tangent angle dresser to dress the wheel to the correct shape. Your thread express would save me from having to make a bunch of masters for each pitch.

[@Threadexpress]

Interesting! Thanks for commenting. Please email me if you want to discuss this anytime. I would also love to hear about your thread grinding trials. Cheers, Cliff

[@furiousg1589]

Personally, I think it's brilliant. I feel your frustration. I think you're trying to apply your engineers logical mind to understand the illogical nature of humans and their emotions. A futile endeavor. I wouldn't pay too much attention to KZbin comments. Most people (like me) are here not because we're professionals, but we either have a interest in machining or it's just a hobby. I love watching videos like yours for hours, but don't even own a milling machine (I am a graphic designer). Just some food for thought. Try not to get frustrated. It's a great invention you've made and I'm sure there is a market for it. Finding who that could be is the challenge. Best of luck Cliff - I, for one, am rooting for you.

[@Threadexpress]

Your good points are noted. Cheers, Cliff

[@bkoholliston]

You certainly have an interesting idea there! I do agree with Preso that it is too large for hobbyists. Once you showed the continuously variable thread pitch adjustment mechanism (last video I think), I thought, well there are only a few choices for coupling the spindle and raising mechanism: One would be cone pulleys joined by a belt and based on the physical size, that seems like it would work; another would be a variable diameter pulley like a Reeves pulley again using a belt to join the spindle and the raising mechanism (lead screw?) but the Reeves pulleys I've seen would all be too big your device so you'd have to make it. A third way would be a flat rubber wheel driven by the spindle and a smaller rubber wheel that moves in-and-out radially to translate power to the lifting mechanism. This is the kind of transmission that every snowblower uses for the drive wheels, but I'm not sure you have seen a lot of those in your part of the world! Ramsden's Dividing Engine was similar to this mechanism. I'm pretty sure based on the size, that you don't have a hydrostatic transmission in there and anyway it would probably not provide the required precision unless make to extreme tolerances (so I'll be very impressed if it's a hydrostatic device). I certainly agree that with all the required bearings etc. to get high-precision operation, your invention will not be cheap to make or sell. Maybe since it turns slowly, it could run in plain cast iron bearings, so having a casting done could be a way to go.

[@Threadexpress]

Interesting points, thanks for your feedback. Cliff

[@prestonengebretson5043]

Hola Cliff, Sorry for not commenting on the First Video of this lovely machine...I would see this used for Repair, Prototyping and Modification of existing parts. Could I or would I like one, Yes!!! How often would it get used in the shop is the Million dollar question. For what we do it would likely be handy a couple of times a month or maybe more. I like the precision of being able to adjust the Helix angle and the quick way to change the Thread Pitch...very handy...I can almost see having it sit on a Dedicated Bridgeport Mill that one could just walk up to and adjust the angles and start working. Very interesting in how it works and would buy plans to build it, though knowing how a small run of Production of this machine would cost you and then your needed profit on top of that...we would not likely be a customer...look forward to your next video...We have CNC and I totally disagree with many saying that they could just use CNC...not in many cases...

[@Threadexpress]

Thanks for your feedback. Cliff

[@tapp1t]

Hi, This is the first video I've seen from you, very interesting. I have an idea as to what is going on and suspect that by increasing the length of the pitch scale you would potentially increase the accuracy. Though this is not necessary, I merely point it out to demonstrate an understanding of what is going on. I am very interested in this or plans for it, I don't think it's a home workshop device unless it was a project, but in the real world I think it may have a place. I'd rather have one or two good lathes to cater for the different sizes of jobs and not have to have the four we have now, each set up for different threads / sizes of work, and to be able to produce higher quality threads would be a godsend. It's also worth noting that by the time the thread is formed on a part there is usually quite a lot of time and value already invested, so anything that makes it easier and quicker has to be a win. I'll have a look at your other videos, but in the mean time I say kick on and good luck!

[@Threadexpress]

[@TSB_To_Be_Or_Not_To_Be]

My guess is that the mechanism is a type of rolling ring gear. Such gears have been known for a long time in various applications. For example, Uhing or in the Haller UFS 155

[@Threadexpress]

Intriguing isn't it! Hopefully soon you will know. Cheers, Cliff

[@ashesman1]

I had once upon a time thought about building a live tool for the tool post of my manual lathe to do this exact job (and maybe grinding too) Easy to get the helix angle too.

[@Threadexpress]

Yes, thread milling in a lathe is very useful. Cheers, Cliff

[@taranson3057]

This is an amazing piece of equipment. It would be awesome if it could be designed small enough to be used on a mini mill.

[@Threadexpress]

Hi - This subject is covered in the recent pros and cons video. Cheers, Cliff

[@ka9dgx]

I'm a former IT guy who took a job making gears (no experience required!) in a job shop... and one of the machines I ended up running was a Lees-Bradner thread mill. I'm retired now, so I'm mostly here to just encourage you onwards. I agree strongly with your views about getting the angles of the thread and helix angles correctly. I also agree that generating the correct thread profile on a 3 axis CNC is highly unlikely due to the same issues. I'm thinking you have a form of a sine bar mechanism to generate the correct pitch, and I'm all for it. I'm curious as to the maximum travel. Cutting threads is a rare enough operation for the home and small shop that you'll see a lot of views like mine, but no viable economic need to drive a purchase. Clough42's "electronic leadscrew" is the most reliable way to run a lathe to get a weird pitch on demand.

[@VoidedWarranty]

Not sure about it being rare to cut threads in a small or home shop, I single point almost every part that needs threads on it. Way faster than waiting on a die to arrive, and I tend to cut a few single point passes to start a die anyway if im going to use one. Really hard to beat a lathe at thread cutting convenience once you get used to it

[@Threadexpress]

Thanks for your feedback. Cliff

[@RogerSchoeni]

Just discovered your channel and new to the idea. Quite like it and if it would be affordable for a hobbyist would love to build one. In a computer controlled world I just love mechanical things

[@Threadexpress]

Thanks for your feedback. Cheers, Cliff

[@theromihs]

Very interesting idea. I can see how this will produce a very accurate thread profile. Just a thought relating to the use of this on smaller machines, could it mounted horizontally, as you have it on the table in your video, and cutting the thread with a d-bit instead? A spring could be added to provide the tension normally provided by gravity? Cutting forces would be quite low, so a spring might be sufficient to eliminate the backlash. I'd certainly pay for a set of plans, were they available.

[@Threadexpress]

Hi - Thanks for your thoughts. Using a D bit only works well for certain thread profiles and materials. The main problem is the tip of a D bit cutter is fragile and does not remove tough materials efficiently and with durability. But for some applications this would be a good option. Cheers, Cliff

[@harry8506]

I can see a use with precision engine building and racing field and R&D, custom and restoration of cars and machinery , maybe even hydraulic fitting manufacture of special adapters that are not commercially available.

[@Threadexpress]

OK, Thanks, Cliff

[@jtbranman]

Great job on this. I have enjoyed following your development. I definitely would be interested in plans. I think it is possible that the people who make the negative comments are ones who don't make screw threads, or they don't understand the significance of your mechanism. I program CNC machines every day and I would like to have a "Thread Express". Thanks for the videos!

[@Threadexpress]

Good to hear your point of view. Thanks, Cliff

[@tano1747]

I would definitely be interested in a set of plans. Whether i would proceed to make one would depend on difficulty of manufacture, which i would have to assess once i could see what i was up against. If it was doable with my manual lathe and mill, then I think would definitely be an interesting project.

[@Threadexpress]

Thanks for your feedback. Cliff

[@Ideasite]

For me, the biggest question is vertical clearance. I'm not clear on how the machine can be oriented. To set it up to cut the threads vertically, as most of your examples show, it would need to hand off the edge of a mill table and would require that the mill head be able to rotate over that axis. I happen to have a horizontal mill with a vertical attachment. It cannot swivel to the location I would need to use the machine. If there were any other arrangement that would place the chuck on the mechanism at a 90° angle to its current orientation, it would fit a lot smaller vertical height and might work for more users.

[@Threadexpress]

I think the main reason for lack of interest would be the cost of it. There is a ton of work and machining involved to build one. Yes it would be fantastic to have such a precision device but when you weigh up the costs to have one are the returns going to be worth that outlay when a similar maybe not so precision can be achieved by the current accepted methods

[@Threadexpress]

Good to hear your positive feedback. Cliff

[@ramviswanathan3301]

Hi Cliff, I wonder if one can use your device for helical or spiral milling in addition to thread cutting. I was thinking your device might have a resemblance to the Deckel FP1 or FP2 helical milling attachment. I believe Aciera and Maho also had these attachments available for their universal tool room milling machines. Those devices were used for cutting mills, drills, taper shank mills, lead screws etc. I like your device, especially the thread precision and the ability to cut to the shoulder without an undercut. Depending on the price, this device could be very successful in the market. Can you cut internal threads?

[@Threadexpress]

Thanks for the feedback. Internal threads, yes. see the other recent videos that give more information. Cheers, Cliff

[@tractor6574]

This is a good idea, keep improving it. We can never have too many machines to do the same tasks. Not all of us part time machinest have CNC machines.

[@Threadexpress]

Thanks for your feedback. Cliff

[@robbailey212]

I rarely comment on line but I think you have an excellent invention here and I largely agree with the points you make in the videos. Due to my personal circumstances I am not in a position to either buy or make one presently but it's something I would aspire to acquire in the future. My second hand lathe was missing the change wheels and acquiring them has been costly and is not yet complete so depending on the price a product like this would be an alternative solution. One addition that would make it more attractive to me would if it could incorporate a dividing head attachment. This may then enable the machining of some complex helical components. Furthermore if its possible to reduce the length it would fit better on my CVA milling machine and potentially Chinese micro mills to. As well as functioning as a rotary table. One suggestion I have would be to lend a threadexpress or do a collaboration video with other machinists youtubers. Four I have in mind would be mrpete22, joepie, abom79 and doubleboost. In the meantime I look forward to your next video as I imagine the mechanism to be like a swash plate in a hydraulic pump perhaps incorporating a CV joint arrangement. Best wish with the product.

Everyday thread cutting (on a wide range of different machines) is not a problem, despite your concerns about accuracy. Your device might make more sense as a thread grinding tool, where all-around accuracy must be higher. But even then, thread milling has severe length limitations, so it only works for the shorter stuff. I believe a manual lathe with a simple motorized spindle on the carriage can do everything your device does, but in a much smaller package.

[@Threadexpress]

Hi. Thanks for your direct criticisms, that is what this video and the comments are for, and you make some good points. First off, I agree that having a well-developed lathe thread milling attachment with helix angle adjustment, with a spindle turning attachment, is very useful. I have both ThreadExpress and a lathe thread milling attachment and I can answer some of those challenges, I often choose to use ThreadExpress over my lathe threadmilling set up for one of the following reasons: - Threadmilling on a lathe is difficult due to steady spindle turning difficulties. So, you also need some sort of geared down handwheel attachment to turn the spindle, as per ThreadExpress. - The set up on a lathe commits the lathe, (ties it up) but Threadexpress is on the table end and does not commit the mill. - Changing ratios on many lathes requires time consuming change gear replacements. EG between metric and inch. - Odd threads are not available on most lathes - Most lathes do not have the ability to index and mill hexagons, squares, grooves etc. Cliff

[@peoplepower1272]

@@Threadexpress Thanks for responding. In my thread cutting experience, I have not ever been forced to make gear changes, so that is not an issue for me. Also, since the lathe spindle is directly connected to the leadscrew, any speed variations are of no consequence and should not require any geared handwheel. Just use the slowest speed the lathe offers and that should be sufficient for most thread milling. Like most people, I find it challenging to run single point screw cutting jobs, so thread milling on the lathe is of great interest to me. I use thread milling often on my CNC mills with great results. A small milling spindle mounted on the compound (similar to a toolpost grinder) or even directly on a quick-change toolpost, would allow setting any helix angle and could be switched out relatively quickly. I would buy a device like that. In fact, a search for such a device brought me to your channel!

I think it's a useful tool, most of the views are going to be by people who are not in a position to use the device, so I wouldn't use view count as a number for potential customers. Out of comments you have quite a high interest rate. Things like this genuinely new and useful tools will take some time to filter through to those who could be interested. Price will be a big factor, but I can see this being extremely useful in any Job shop.

[@Lwimmermastermetalart]

I do believe it’s quite a bit of genius. I’ve been a journeyman toolmaker since 1976. When I first started my own shop one production part I made I used a Geometric (brand name) die head in a turret . Very good threads and would cut to the required thread gauge very quickly. Then as years went by I had several CNC lathes and mills. I’ve cut single point threads all the time. However I do see the logic in your process. I would love to see what’s under the cover but understand if you don’t. I’ve invented quite a few things in my life and found utility patents to be way too expensive. A design patent is simply a waste of money. While I can certainly see the value in your product I still believe it would only be appealing to a certain amount of shops. I still think it’s brilliant however the only thing I don’t like is the size of it. To put the unit on a mill it will sit so high up on the table. Now if you have a power knee feed that’s not so bad but if not that’s a LOT of cranking. I do hope I can see the inside. Maybe not put it in a KZbin video but perhaps it could be emailed to seriously interested ppl somehow. Heck if you do decide to put into production of any quantity I’d love to have the opportunity to quote you on components. My sons have bought my shop now but could do components at a very competitive price. Especially in lower volumes. Overall I love the video and hope we can further discuss this. Good job young grasshopper lol 👍🏼👍🏼

I’m fascinated by this machine. I’m a hobby machinist so money would be better spent on tooling or machines. If the price was reasonable I would purchase plans. I doubt I could afford to have you manufacture it. That being said this mechanism seems superior to many other processes. I think you should continue your journey, a market can be created for your invention if one doesn’t exist already. Many great discoveries from great men have come in their dreams. Don’t waste your opportunity, the universe was speaking to you.

[@davidclark5975]

There defenitly is a place for this tool. A very unique well thought out design. What would it cost for a unit? Most machinists would simply use their lathe, I think that would limit to how many you could sell. However the money would be into selling to the small shops that have the smaller mills or mini mills. Have you given any consideration in trying to scaling down the size?

I'm as intrigued by the mechanism as most people seem to be and you are to be commended on the design, but, from my point of view, I machine threads from around 4mm diameter up to 4 or 5 inches (hydraulic cylinders usually) I don't need "super accurate" threads and your machine wouldn't be physically capable of doing the diameters I need. However, you have got me wondering if incorporating a thread milling spindle to use on my lathes would provide any advantages ?

[@machinewrangler4682]

I like the concept and its benefits over thread turning, Nice little mechanical movement inside. At a guess you are using a sine bar type arrangement. I’ll admit it’s a difficult task to make a z axis stage that doesn’t take up a lot of height/space. On one other note, with out trying to sound negative. Now you have a working mechanical prototype, have a crack at an electronic prototype, plenty of Electronic lead screw kits out there. The extra initial cost to use electronics is saved by simplifying the mechanism and reducing production time. Just some thoughts from a toolmaker. But I like what you’re doing.

To be able to type in say any lead from 0.001 mmto 150 or more with the press of a few buttons is pretty appealing. Not only would one be able to cut threads but cut helix’s, even rotors for small progressive cavity pumps, (just thought of that one then) I’m sure the list goes on. Sorry I’ll stop waffling on now!

[@weldmachine]

Cliff you're a really nice guy which in my experience isn't too difficult to find in a fairly typical Kiwi. For that reason alone I would love to see something good to come of all the work you have put into to building and designing the Thread Express. But ??? Being a little more honest about it's practicability I would personally find it difficult to find an end user. It's a little to do with the design as much as finding a genuine customer base. As a kit, for someone to build who has more time than money, I could see a small amount of interest. Commercially ???? I personally wouldn't spend too much time trying to find a commercial market for the Thread Express ?? ( but I'm sure you already know that by now ) Most machine shop based operators don't want to think too much about how something works. It either works fairly easily without too much effort or they're not interested. I talk more about the smaller shops that usually have a small customer base and just want to be involved in the smaller jobs than the shops who have multiple employees on reasonable wages that need to be paid. The Thread Express is bordering on trying to reinvent the wheel. It does work as it is intended. But, does it replace what is currently available ?? From a prospective customers point of view. WHY buy a Thread Express ?? Does it do something that I can't do currently ? IF you can answer this question you might have a starting point of how to sell the Thread Express. I feel you're possibly too personally involved with the Thread Express to see it's value to an end user ?? Just some insight to my thoughts about a fairly typical small machine shop who could be your end user ?? Less and less of these shops are in operation now. IF you can find 1. They are in most cases fairly tight with their budgets and prefer to waste time on a job than spending money to buy the right tool. Scaling up from this fairly typical operator. Someone who has 1 or 2 possibly 3 employees. The mindset is to gain and grow the business. Most already have CNC capabilities or they are seriously looking at getting into CNC. This I feel is most of the reason Why you're finding it difficult to find an end user. You only need to watch KZbin to see a guy in a garage with an okay setup that's producing parts on a budget CNC Machine and most of these guys have the mindset to follow the trend and get serious about CNC equipment beyond their current setup.

I am interested but the cost is what’s holding me back. I’m expecting something this amazing is going to have to come with an amazing price as well.

Add to that the fact that I have two lathes and a mill and taps and dies. It is an amazing machine. I still would like to pursue one. But cost is a big factor for me personally.

I think it would be amazing to have one, but it comes down to utility. Since I am just a hobbyist I usually have more time than money. So if something like this were $400-500 I would be interested.

[@murrayedington]

I suspect most viewers of your channel are amateurs like me. The need for male threads is fairly infrequent and when the need arises I will either use CNC lathe, CNC mill or die. If I ever needed to make multiple instances, I'd probably use a Coventry die head which is quick, accurate and repeatable. The cost and size/weight of a dedicated device would be difficult to justify against the benefits it offered in my case. As an engineer, I'm intrigued to learn what you have created here. I'm looking forward to the next episode! As for the helix angle error resulting from use of inserts, I doubt many of us here even understand thread tolerances and generally rely on "hand fitting", rather than specify meaningful GD&T style tolerances and then machining to them. The helix angle error results in a slight widening of the thread angle but TBH it's generally a small error in the scheme of things. It's just about possible you might be able to sell the design to a manufacturer but without a patent you'd be on a dodgy wicket. And even with an expensive patent, you'd have your work cut out trying to enforce it if you got it made in a low cost country.

What is the realistic profit margin that would go in your pocket if you had to hire a company to produce them for you? Hundred Dollars? Couple hundred Dollars? I think good plans and/or partial parts kits (not everything piece of metal needed, maybe just the more difficult pieces, like the graduated dial around the chuck etc) would easily sell for that. Netting you the same profit without all the hassle. Plan's would have to be drawn up no matter who produced it.

[@VoidedWarranty]

with the demonstration at minute 18, I have to disagree. If the cutter is digging in behind the point where the 60 degree plane is, it does not have sufficient relief or is fed too fast or is too coarse of a pitoh vs the diameter for standard thread filling, in which case the high precision shops around here choose a different process such as the lathe. the deepest contact with a properly on center tool is at that center line. Additionally, if you apply the tool to it not aligned with the top down view of a thread form, you have to make a cutter that has an angle wider than 60 degrees to form a perfect 60 degrees in plane with the print. the nc argument falls flat if you consider the other capabilities you get for free with an nc device. Slotting, single point broaching, indexing, automatic multistart threads, constant feed rate. Also itdoes not need a ballscrew or a sliding quill, because its trivial to track the other movement axis on the mill and use that instead. I'd tap of| of the dro scale and have a simple nc rotary table track rotation accordingly if I needed to make such a device. Any of| the shelf dividing head, which has built in helix angle capability if thats important to you. But honestly I do this work on the lathe without runout grooves by threading away from the headstock. Simpler than anything I mentioned. Not sure why high tensile is a concern, I dont usually machine anything lower than 4140 and I basically never use a cheap common die for anything that is not a bolt, I single point anything that needs precision on the lathe.

Don't be disheartened by the views to comments ratio on your previous video. I had a video go viral (not this account), 600k views and 800 comments, or 750:1, your previous video was approx 86:1 which is quite good. Also the number of 'views' includes people who clicked away early, the number of people who watched to the end is likely much much smaller so your amount of comments shows excellent interest/response from the audience who watched the whole thing (me included). The key to making a promotional video for something (where the goal is gaining a wide audience to get as many eyes on the device as possible, which I think was the goal of the first ThreadExpress 2 video from 8 months ago) is to keep it extremely short, explain what it is and what makes it different within the first 30 seconds, keep the total length of the video under 5 minutes (many people wont even open the link for long videos), and edit the demos down to very short (eg 15 seconds) clips, and at the end let the audience know there's a longer form video with more info and demonstrations linked in the description. I know it sucks as an engineer to try and explain your achievement in three sentences when there's so much relevant detail etc (I fight this battle all the time myself) but only your existing fans will want to watch a 30 minute video about it whereas you're trying to reach the widest audience possible, one that hopefully includes deep-pocketed business people who expect an executive summary of everything. One of the skills that took me the longest to learn as an engineer is how to present information in a way that the idiots making decisions would be receptive to. As for the device itself: I'd love to make one, I'm super curious about how it works, and I likely can't afford one :)

[@nickp4793]

I'm impressed with the mechanism and am enjoying your videos. I personally think you should quit. I don't think you will sell a single one. (sorry I lost track, are you considering selling complete units or plans). I'm in RD myself as a mechanical engineer, and the time it takes to go from a working prototype to a production design is huge. You won't have any payback. It will all be a huge waste of time, if an overall profit is the goal. Legit machine shops won't be interested. They about all have VMC's. Hobby shops won't be interested. They might need this once per year, and they'd be better off using a lathe with single point cutting, since it's so infrequent of a need. They already have the lathe. Maybe some sort of specialized instrument maker would be interested, that needs high accuracy thread forms. But like you mentioned, they already use grinding setups with adjustable helix for threading. If you sell these complete, you'd have to sell them for at minimum 1000 USD to even make getting out of bed worth the effort. Probably higher than that even judging by your prototype. No hobbyist is going to pay that. If you sell the plans, you are going to have to design the whole thing for a hobbyist to be able to source, machine, and assemble all the parts accurately. That is harder than designing for mass production (commercially) because you don't know the tools and skills the hobbyist will have. Quit is my strong opinion.

Looks like this does great work, and seems like you've poured a ton of inventiveness into it....i wonder if it would be amenable to a design where it could be produced in cnc, at least the majority of the parts. If you could nail that down, it might give you an idea of what kind of pricing you could manage in different quantities. Do not, absolutely, go to certain countries for production, as i personally have seen products stolen, and produced for the asian market, three or more times...during my days at a major mobile phone company, fhere were often 'look-alike' products on the market in that large country, before we had completed the approval processes ... never mind that the internals were crap, 'appearance', and 'status' were all that counted, but intellectual property theft occurred at shipping companies, and even in the customs offices....

I get that there's an error in a threadmill in a VMC because the spindle and the thread are co-axial and not taking into account the helix angle, but if you're using a small diameter threadmill, how much is that error? 1%? 5%? Obviously if the error was unacceptable in most cases, people wouldn't do single point thread milling in a VMC, yet it's done all day every day, and meets customer specs and tests. I am curious to see how the mechanism in your device works. I don't think it will ever "takeover the world", but in specialty applications where the utmost precision is important, it could be just the thing!

[@Threadexpress]

Hi - Thanks for your comments. I agree, if you are using a small diameter threadmill on a large diameter fine pitch thread, the error will likely be minor. It is when you are cutting a small diameter coarse thread or using a larger diameter cutter, the error produces a sometimes unknown out of spec issue. But it is in shops that do not have CNC at all, that I think ThreadExpress will be the most useful. Cliff

[@tigordie2916]

I feel like you need to speak with someone like titan over at titan CNC. He would have a better idea of its place if any in the machining industry.
