Hidy. I've been doing machinist / tool & die and job-shop work all my life 60 +/- years...! and I've never seen, nor thought of; this concept! Thank you, SO MUCH, for demonstrating this concept! And thanks for making this video! It blew this old man's mind...!
When working for my uncles in their small shop we used to manufacture small worm gears for a company that used 1/2-13 threaded rod to make their worms. We cut the gears on a Barber-Coleman #3 gear hobbing machine using a 1/2-13 tap. Obviously you need to calculate the proper diameter of the gear blank but using only the downfeed of the machine it produced beautiful throated worm gears by the hundreds. Nice video.
@@user-ec3ij6mt3p We converted the 1/2-13 UNC threaded rod to the comparable diametral pitch which is 40.83 DP. Using standard worm gear calculations for the 100 tooth gear (number of teeth/diametral pitch) give a value of 2.449 inches for the pitch diameter. The worm gear in this case was throated so standards call for the throat diameter to be the pitch diameter + (2 X addendum). As this was a non-critical application we chose to treat the addendum as one half of the whole depth of the thread (in this case .0472 inches) and add that to the pitch diameter. The outside diameter of the worm gear is pitch diameter + (3 X addendum) so the finished bronze gear blank ended up being 2.520 inches. OD = PD + (3 X addendum) Hope this was not too confusing.
An important thing is that this requires the circumference of the gear to be evenly divisible with the thread spacing on the tap - else you get overlapping threads in the gear.
That's what I was going to ask. If its a 1mm pitch tap the circumference of disc should not be decimal point. Should this be at the start of machining or what?
Fascinating! It is also interesting to note the 50 cycle strobe from presumably fluorescent lighting which is why tungsten machine lighting is favoured. Excellent ingenuity!

Hi. Did you (or somebody) tried the same with trapezoid tap? When I found this video, I realized this could be the way to make my own thread chasing dial gear.
@Ol' Camo Somemthing that I have figured out over the yers is that there are many different kinds of machinist. You have folks that make one off parts, they tend to have tight tolerances and can take more time to achieve prefection and people that are what I call production machinists who focus more on speed and just stay between the linse as perfection only adds cost. I find that someting these two groups but heads a bit. There is also a line between manual and CNC machinists or even mill and lathe machinists, they to can be a bit tribal. Point is that if your making parts for a living your a machinist hell you could only use a file to make em and still call yourself a machinist the only real question is are you a good one and even that could be subjective.

Excellent idea for meeting the requirement of small gear pensions & This is very much helpful to manufacturers without having a expensive gear cutting machine !
@@sinisterhipp0 I came looking for the answer here to so the round has to be the correct size , or you will have to watch until the threads come together .
This is a very good way of making a Worm & Gear, the really neat thing is it always seems to sort itself out as regards pitch, or at least it always has for me, I have used this method on a wide variety of sizes, always works.
Were you making a new worm + wheel system or doing a repair for a current system ? And can you always use a tap or do they make specialist cutting tools for this ?
I used the same method to make 12" worm gears for my telescope, using 1/4" 6061-T6 Alm plate on a 6" lathe. The key, is to have the center bore first, the hob the teeth. As I was not after a specific number of teeth, I just hobbed until full depth was reached, and no partial teeth remain.
using this method you are machining the gear with varying pitch diameter because you are using the cross feed. What I did was to machine the od of the blank with a groove matching the id of the tap and a circumference which is a multiple of the pitch of the tap, Then bring it in with cross feed onto the end of the taper of the tap. Then use the saddle to feed the gear onto the tap. The cut is done always at the same diameter on the wheel.

How would you ensure that the point where the threads meet on the new piece are equal to the rest of the threads? It seems as you cut deeper into the material, the point where the threads are cut at the deepest point may not be equal given the circumference. In essence, the point where the new teeth begin to be cut off by the tap
Out-f**kin-standing!! I would have never thought of using that setup to cut a gear...and yet, with the center keeping the tap from deflecting, it makes perfect sense. I'm amazed by your machining cleverness.👍👍👍
I need to make something like that , i have tread dial with a missing gear that runs in the 4 TPI lead screw . I have a 4 TPI Tap but what size round do i start off with ?
Really clever!Did you have an application for this gear? I am curious about the final shape of the teeth: Are they somewhat involute? I would presume that they might be due to the entry and exit of the stock into the tap. Now I am tryna think of some sophisticated application of a gear like this... Thanks!
Well that's nifty. The engineers are always asking us to do nutty things with little to no proper tooling. Always good to learn something new. This is going to be categorized under what I call "old guy tricks" I've learned many many things like this from guys close to retirement many who I have since replaced at various jobs over the years. Also handy if I ever need a small worm gear made at home with my little hobby lathe. I'm sure I could figure it out.
Hello! I think other taps with thread and pitches could be used, the smaller pitch the easier work.. I needed as big pitch as possible for that gear, so I use M12.. The only trouble is to count diameter of the gear accurately to have the teeth evenly placed, without a gap..
How do you ensure the gear meshes when the worm has turned 360, or did you just keep pushing it into the tap until they do? In which case each movement of the transverse will cut on a new circumference and the new cuts will be out of sync with the previous.
Константин, раньше. Я такой способ видел в какой-то технической книге 70-72 года выпуска. Там же и приводились формулы для расчета наружного диаметра нарезаемой втулки в зависимости от шага резьбы. Они несложные и понятные. К сожалению это некая эрзац червячная передача. Подобие.)))) Для несильно нагруженых механизмом пойдет.
This is mostly just for making a worm gear without a specific number of teeth, but you could do some calculations using threads per inch and circumference of the circle to determine how many teeth you would get at the end.
Только не токаря, а фрезеровщики. Работа для зубофрезерного станка, просто в данном случае в качестве фрезы - метчик, а фрезеровка выполняется на токарном станке
and still i am always wondering how the start and the end of the gear groves will come to a magic overlap - especially because the diameter of the work piece will start to shrink during machining. (same wondering when it comes to grid pattern engraving on a late using a set of rolling engraver wheels put with some pressure onto the work piece...)
You are right. It seems like magic. I think the diameter has a lot to do with it. The diameter would have to be divisible to the thread pitch; I think or something like that Joe Pieczynski has an alright video on knurling. It deals with timing of knurls, and the diameter affecting the final outcome. I know its not the same just some food for thought.
I made a 350 teeth alu worm wheel for astro use some years back.I paid great attention to perpendicularity and to keep vibrations under control.I used a ball bearing cell which the toothwheel rotated on, i fed aprox. 1/3 of the diameter of the actual taper(cutter) and technical alcohol as lubricant.No oil when working with alu!
Good job, but now you need a spindle to the same pitch... OK, I get it... a screwed shaft to the same pitch as the tap! Not perfect but near enough for light work! Brilliant!
You could use a die of the same thread. I used this method of worm and wheel generation for model tram drives. The smallest I made was 3/16" BSF. With 10 BA grub screws to fix them to the axles.
Clever use of a screw tap. I myself have 35 years of mechanics and never had seen this trick. But you had to calculate the primitive diameter of the blank, to get it right. Maybe using a tap with spiral grooves the cut is smoother?
Any diameter will be fine as you will just grind it until everything fits, if you chose wrong diameter you will just need more time. also he is not moving everything up down so he got worm gear.
Blank diameter is figured as follows: (thread pitch) x teeth number desired divided by Pi (3.1416). Example if you used a 1/2 x 13 tap and wanted a 72 tooth gear. Ex: .0769" Thread Pitch x 72 teeth = 5.5368 divided by Pi = 1.762"
Thanks, this video appeared just at the right time for me. A simple jig for my mini mil or mini lathe and I should be able to cut a large worm gear. Thanks again. Now then, I wonder if a matching die could cut the matching worm?
Completamente de acuerdo, el bronce en sus distintos porcentajes de aleación permite ser mecanizado sin añadir lubricante debido a la estructura que forman, los metales y los no metales, permitiendo que el arranque de viruta requiera poco esfuerzo por parte de la herramienta . Por otro lado la fundición, posee intersticiones de grafito, que es un lubricante natural
The OD of the part has to be figured out by the number of teeth on the tap. Number of teeth divided into the circumference. You play around with the diameter and teeth until it is even, no over lapping.
I've cut a few gears during my many years as a machinist . I gotta hand it to you, this was a great idea and really inspired me to open my mind an think outside the box. Great video

Brilliant! That is a great idea
Good job, but now you need a spindle to the same pitch... OK, I get it... a screwed shaft to the same pitch as the tap! Not perfect but near enough for light work! Brilliant!
As the lathe starts cutting the gear, repeat to yourself, "I think I can, I think I can, I think I can..." It goes in time with the lathe.
Great work mate, going to try this myself now👍
How do you calculate the diameter of the blank for the gear? Very impressive video as usual of course.
+cerberus Dalibor is really sorry but he is, "stuck in his own work".
+cerberus I think it must be close to 2 *PI * thread pitch * tooths
+Federico Devigili thanks for the help. I will make note of this and give it a try.
By supercomputer power!
Circumference measurement and accommodating thread count?
At 4:04 i imagined somebody playing thunderstruck, but it didn'happen :( Very nice anyway! :D
This is one of those right in front of your nose things you hardly see coming. Awesome idea to use a tap to make a gear.
You could use a die of the same thread. I used this method of worm and wheel generation for model tram drives. The smallest I made was 3/16" BSF. With 10 BA grub screws to fix them to the axles.
Thanks for the education that's a pretty sweet trick ....

You lost me the second I saw the IKEA crescent wrench. :40

I assume that he must have had to assemble it.
We all have tools we bought on impulse or it was the only place open when you really really needed a tool
Damn, I saw that and I thought I must have been mistaken.
So?!!
It's a tool that gets the job done. That's all that matters.
Nice, I never have seen this technique before!
Those chips on the workpiece are all like "weeeeeeeeeeeeeeeeeheeee"
Clever use of a screw tap. I myself have 35 years of mechanics and never had seen
this trick. But you had to calculate the primitive diameter of the blank, to get it right.
Maybe using a tap with spiral grooves the cut is smoother?
Any diameter will be fine as you will just grind it until everything fits, if you chose wrong diameter you will just need more time.
also he is not moving everything up down so he got worm gear.
Blank diameter is figured as follows: (thread pitch) x teeth number desired divided by Pi (3.1416). Example if you used a 1/2 x 13 tap and wanted a 72 tooth gear. Ex: .0769" Thread Pitch x 72 teeth = 5.5368 divided by Pi = 1.762"
Best Racing Tips Win At The Dragstrip Now we have blank diameter rightly
calculated. Thanks.
registered. thanks.

mayb not so critical as the cut deepens..
Nice! Terrifically easy to do. I'd put a mark on the blank to guide me when to do the next in-feed. Other than that, this is a total win.
ExtantFrodo2 there was a mark ^_^
“Great job! I would have done this because I’m perfect. However, you’re not. Nice effort!
It's doesn't work ;like that
That was really cool. Thanks for sharing!
I like that he tightened the spindle with pliers then sanded off the marks with his bare hand. He must have some very rough skin.
Now I know why there is a center on the end of taps!
Thanks, this video appeared just at the right time for me. A simple jig for my mini mil or mini lathe and I should be able to cut a large worm gear. Thanks again.
Now then, I wonder if a matching die could cut the matching worm?
A bolt of same thread
cool thread gear making trick, I never thought of it, good job sir
Completamente de acuerdo, el bronce en sus distintos porcentajes de aleación permite ser mecanizado sin añadir lubricante debido a la estructura que forman, los metales y los no metales, permitiendo que el arranque de viruta requiera poco esfuerzo por parte de la herramienta .
Por otro lado la fundición, posee intersticiones de grafito, que es un lubricante natural
Hi Jamie, I didnt change the tap, it is in original condition as You can buy it in store..
How could you know that the teeth do'nt overlap each other after making a complete 360° turn?, think you do a great job!!
The OD of the part has to be figured out by the number of teeth on the tap. Number of teeth divided into the circumference. You play around with the diameter and teeth until it is even, no over lapping.
it's called math

I've cut a few gears during my many years as a machinist . I gotta hand it to you, this was a great idea and really inspired me to open my mind an think outside the box. Great video
Todd Kratzer I know, but the diameter is even not always the same, when he cuts in the metal...🤷🏻♂️
Nice. Do you have a good(read: simple) formula for deciding starting diameter if you want a specific gearing?
Great idea and video. Thanks for not adding any background noise.
