Ive never seen a worm gear made like that before 10/10 top job for that one guys 😁😁👍👍
Technically it's a Worm Wheel.
Been a tool and die maker all my life. This guy is brutal but the standards must be low where he is. Surviving any way possible.
Agree, brutal, not amazing.
I'm normally very critical of videos by shops such as this, because of the horrendous working environment and the total lack of anything resembling safety. My other pet peeves are when they hammer on parts in the chuck and welding on parts using the lathe as ground. Both of those habits tend to destroy the internals of these machines.
That being said, this technique is very creative and this operator should be commended on his "out of the box" thinking. I suspect this was a demo as the part has no reasonable function as-is but nice work anyway!
Now keep the damn hammers away from the machinery and if you have to weld on a part chucked in the machine, clamp it directly! Take care of your tools and they will take care of you.
Totally agree
Methods and outcomes are rather different in our part of the world. Locally produced lathes and tools remind one of older practices and designs. Training is done through the old fashioned apprentice system. It is a ‘hand and eye’ approach to things. Surprisingly, one does not hear about many safety-related incidents, although such workshops are found everywhere, and they produce all sorts of things
I've taken to cold chiselling parts in the four jaw chuck mounted on the lathe. Also I often weld stuff in the lathe. Earth the job not the machine. I'm no the worst thing to happen to it. Had broken teeth on the back gear I had to repair. But you are right about misusing a three jaw self centering chuck. If mistreated they are never the same as new again. Always run out .
... "no reasonable function"??
It is a perfectly usable worm gear that will mate correctly with a worm made from piece of threaded rod of the same thread size and pitch as the tap that made it.
And because it was mounted by its own bearings the gear teeth will be concentric with the bearings.
It is an excellent gear, and a very practical technique. 👍
@@riazhassan6570 Thank you for your feedback. I'm grateful that your workplace injuries are low... In my corner of the world workplace safely regulations wouldn't allow us to work in conditions like those in this video. Sadly most of our regulations are due to my country's reverence for lawsuits and high-cost claims for injuries. Many times, these injuries happen because of lazy work practices and relying on safety measures to prevent injuries.
For example, in many videos from your country, I see men working around molten steel workout a single protective device except possibly wearing gloves. Long loose clothing, sandals, etc. They do so safely because they realize the danger of not concentrating on their task. Unfortunately, if something does go wrong, the injury will probably be severe. In my country, protective clothing and equipment will keep a workman as isolated from the molten steel as possible. If an accident does happen, the injuries will most likely be less serious, but more injuries and accidents causing lost time take place because the workers are lulled into complacency because of the safety systems. I know people from America will angrily refute what I'm saying but here's a statistic that proves my point: A very steep, winding road through high mountains (the Colorado Rockies) had some fatal accidents because there were no guardrails protecting vehicles from going over the side and falling down the hill. So the state put in very robust guardrails to prevent those types of serious or fatal accidents. It's common sense that fatalities on this road would go down as a result, right? Wrong, fatalities went up, because drivers drove faster and with less care BECAUSE of the guardrails. This caused different sorts of accidents, but the fatality rate went up anyway. I WOULD like to see better working conditions in your area, but I'm gratified that your injury rate is less than one would assume.

This is the kind of innovation I fear that American machinist are losing with the computer generation. Great job dude.
Đúng là Mỹ , Nhật , Hàn , hay châu Âu ...không ai có thể nghĩ ra cách làm này !👍
@@vanquynguyen8298 and worse, when we see those that can, far too many belittle them.
Yes, I been a machinist since 1987, I still can make gears and threads on manual lathes, but I been programming running cnc lathes for about 15 years now, times are a changing
@@ricmorles3237 I started my first job in ‘85 and now run my own one man shop. No cnc allowed. I dont consort with the robot kind. Our generation is pretty much the last of the manual machinist in the States. 3D printing is gonna sneak up on the cnc guys and obsolete them before too long. Space X boosters being a good example of whats possible.
When doing this sort of work, how do you know that the diameter of the workpiece matches the thread pitch? I can see a situation where the next turn will not quite match the previous thread and you'd get a real mess.
Well, if I understand correctly, normally you do a some of math, dividing the size of a tooth into the diameter. But it is a bit more complicated than that.
Amazing skill. Was a machinist for 20 years and have never seen anything like that. Notice he never used an indicator.
@@AndrewHager-he1pcJesus Christ. I read this while high AF and I think I got cancer.
Me diste una idea para fabricar una máquina para fabricar esferas del diámetro q quiera grasias colega
It is fascinating to see that how a simple technique can produce complicated parts.
Первый раз такое вижу, молодец👍🏻🤝🏻
I work on modern CNC lathes/mills and watching this while eating was not a good idea. I was so worried that something would go wrong...but it didn't.
And it is neat to see how one can unleash their creativeness to do so much more than the less modern toolset initially allows us to believe. :)
This is how it was done before the 90s
everything is in their heart, bro
I work on some davenports literally 100 years old, using old tools and turning out modern parts. There thread rolling attachments were amazing and if you haven't seen how the machine threads. It uses a method similar to procunier tapping heads utilizing a high speed and low speed clutch.
The machine and it's tools are absolutely well designed with innovation bleeding all over.
@@candlestyx8517 It's still done this way there will always be more than one way to skin a cat. Similiar to my other post working on older machines requires intimate knowledge of jig design and toll making.
A lot of it is seat of your pants need it know, but need it right and usable next time you need it now just for the one oddball job.

And mashaALLAH GOOD JOB
I've done this in 80s with manual milling machine. Just like you I brushed chips away but used also cutting oil.
ประเทศนี้เก่งมาก ซ่อม ทำได้ทุกอย่าง ชอบมากๆๆ เจ๋งสุดๆ จาก Thailand
If you didn't have the right involute cutter to do this properly you could pre-shape the gear with a dividing head and a home made cutter that was just triangular in tooth profile to get the number of teeth and depth pretty much right, then you could use this technique to get the involute geometry pretty spot-on. Using it right from the get go is going to look alright but the geometry is going to be off, because the number of teeth will be set once the grooves start getting deep enough to force the following cuts to follow. Then as you feed into the tap your effective diameter reduces but the number of teeth doesn't; causing binding and leaving you with incorrectly formed grooves in the worm gear.
Still, you make do with what you have and this would better than nothing.
Rightly said. But alas he’d understand absolutely nothing what you mean. The thumbs up in the end says it all.

I'm a machinist but cannot work like that. I use proper machines for its proper job. He's like a lathe already. 🤣🤣 My boss will b mad at me 4 such a work. 🤣🤣
I am a retired Machinist. I did work like this when I was a machinist but this, THIS is just a a pile of crap. One doesn't use a tap to make a gear. What is it supposed to mate with? To what does it match with? What is the pressure angle and what is the pitch? Where are the gages and I did see this same thing done on "mekanik messin" a week ago. I guess that's why I call it, " mechanic messing." They do not want to do anything of a constructive nature. At least he has a workbench!!! 😅
Matches with a both with the same thread pitch
I am impressed the shop isn't filthy and the lathe hasn't been beat on and abused great work
I always liked cutting brass on the lathe. I makes chips just like cutting cast iron. You don't need a chip breaker cause the nature of those two metals makes it impossible to make stringy chips like 304 stainless.
I don't put anything past these guys. If it needs to be made, they WILL make it.
Из 130мм на 80. Роствертол. Нормально. Страна багатая! Можна!!!
I did the same thing ina milling machine. Just turned up an Arbor out of bronze for the piece to rotate on and held it horizontal in the vice jaws, that way you can use the X feed to also cut across the whole surface, not just in the middle.
Fantástic Job congratulations, God bless you

Good idea. The main advantage is that unlike gear hobbing no drive need to be given to work wheel which macks the machining simple. However required profile matters. Idea can be useful for repair work where spares are not available.
U have to admire their skills they are working using the tools and metals that are to hand and creating, could you do the same as them with the same tools etc I doubt it, so give them credit.
Yes I can and yes I have. This is sloppy unskilled work.

@@billshiff2060 I cannot see you making those parts on anything but the latest computer controlled equipment. You probably only push a few buttons. And if you do make them in any way no wonder Boeings are falling from the sky in droves.
Wow, you make it seem so easy👍👍👍
The circumference of that wheel needs to be precise in order for those threads to be continuous
My thoughts exactly
Is that how he did it? I'm over here wondering. 20 tpi tap, 3 inch diameter so 60 teeth? Is that how it's done?
@@gitar1hero1qaz If you want to do it this way, and it is possible, and you need an exact number of teeth, you absolutely must calculate the throat diameter of the worm wheel, and you absolutely must pre-gash the cuts. The calculations can be had from "A treatise on milling" amongst other early-20th century sources that are easily and freely available.
The throat diameter of the wheel is not the primitive diameter of the final gear, and without pre-gashing, the tap will do its own thing. Generally speaking it will try to cut 2-4 extra teeth, and you'll end up with one area of the wheel with "mushed" teeth. Plus, it won't match up properly to your worm. Ask me how I know. Ask me why I had to redo my worm wheel that was originally intended to have 60 teeth, and recut it for 55 teeth.
Yeah, material is expensive.
@@wibblywobblyidiotvision why
@@gitar1hero1qaz I'm pretty sure he didn't work with inches, but I may be wrong.

Gear profile is involute. Taps produce only V form. Technique is good but will work for short while & also does not carry the required load.
That's the way involute gears are formed, it's called hobbing and a hob has a tooth form more or less like a gear rack. The gears produced by hobbing produce in involute gear tooth. There ate other issues with using a tap as the hob but tooth form isn't one of them.
If you need some shims to put under the Turning-Tool, try and obtain them from an old transformer, I find them very handy.
Amazing technology 👏 🙌 👌 👍
Very nice video. I would say this part is in bronze and for boating at first sight. Not a gear.

Muito bom amigo, vcs são demais Parabéns!!!!👏👏👏
Despite some of the critical comments below, I gave the guy a thumbs up for producing a usable part in not ideal conditions, you critics could not survive in his world without your cnc and tool room precision machines, think before commenting!
That is NOT a usable part. That's why it's not shown in use. It is a stunt he saw all over the internet and copied it. You don't need a cnc to make junk.
@@billshiff2060 Where is your evidence that the part was not used? just because it wasn't shown in use,🤣🤣! so all the parts you ever made that no one recorded in use must have never worked then 🤣🤣🤣what a bell-end statement Bill!
@@rottenbot It was not shown because it is useless. You obviously know nothing about mechanics or machining. THAT is NOT how a worm wheel is made or designed. He is just apeing what dozens of other videos show, all producing a useless part. I have made ACTUAL worm wheels that ACTUALLY function and they are NOTHING like this garbage.
Free hobbing is an actual technique but it does NOT use a freakin TAP, what this bozo calls a "thread drill", and the free hobbing is only the LAST step in the process as a final finishing AFTER it is cut on a milling machine/indexer. It does NOT use a tap it uses a specifically designed HOB.
This junk may impress YOU but it will not impress anyone who KNOWS what they are looking at. The only thing this trash can do is get clicks.
как рассчитал шаг резьбы и диаметр заготовки что бы всё сошлось?
Это не резьба...
шаг резьбы умнож на количество зубьев (в данном случае количество борозд .. потому как зубом не пахнет ) получишь длину окружности ....

Good job

Tool could be a little bit sharper not sure of angle needed for brass ? Can be driven by a threaded bolt .
Actually, this is a good one, of course there's, an uncertainty factor, you may end up with not the exact teeth you intended but mostly random plus bad tooth symmetry, since the first pass decides that and half a tooth at meeting point is hard to... uncut. Just forget high loading, the shearing surface is small and not optimized. For light duty high reduction it's fine.
If the gear is gashed with a slitting saw first the tap will follow the gashes and you'll get the right number of teeth.
The only function this "part" has it to make a video of making it.
This may look like a correct formed tooth, but it's really nothing more than a bodge. A vee thread is nothing like a gear tooth form. Expect high wear and a short life.
Even though the tap has straight sided V teeth, the cut won't have straight sides. The tap will give a reasonable approximation of an involute tooth profile (in essentially the same way a normal gear hob does). That said, an Acme tap (if there is such a thing) would give a profile a lot closer to what you'd normally expect for a worm gear.
Most of the work done manually how precise it'd be 🤔

Another great video,very talented.
Fantastic skill by being versatile.
I completely understand there are millions of Americans who know basically nothing about the trades and how anything in life is accomplished. It’s still important you know that if this machining process impresses you- you would be absolutely blown away by what Americans were doing in the 1940’s.. lol
America would still be a superpower if they kept the trades at home and didn't ship it to third-world countries, now our kids become starbucks "baristas" and learn how to press a button to make the coffee. "Learn to code" they say, but you can only have so many IT jobs before a tractor breaks down and you need to import a gear or something, made from the workshop in this channel i guess.
@@JOSEPH-vs2gc what really made me lose hope in the long term future of America is after we experienced shipping halts and everyone found out all our medicine is made in se Asia during Covid there wasn’t one effort made to remedy any of that. Even with the knowledge that had Covid actually been really serious like something in the future could be; nothing. Everyone went back to fighting about race and grooming children. So my family is stocked up and armed to the tooth. Everyone else can suck it.
I was a tool maker before becoming an automotive powertrain engineer. I've worked on knee mills and manual lathes to 5 axis CNCs and automated machining equipment turning out cams and crankshaft. But I still thought this was pretty innovative when they don't have a hob they have to improvise.
@@JOSEPH-vs2gc nah. Kids today are smarter than us and the US is the world's leader. The "trades" can be learned by anyone. The bar is so low that even people in India can learn it in the most impoverished conditions. Kids today are pushing the envelope and developing new technologies that others will have to play catch up to. Being able to make a phone or computer is a lot more marketable skill than being able to turn a wrench. No country was ever a world leader without setting themselves apart with technology. From ancient boat builders, to the industrial revolution to the computer age, the world's power houses did things other countries couldn't. Don't become a grumpy old man, embrace new opportunities.
@@theupscriber65 I'm in my thirties not exactly old, but not young. and this maybe the stupidest and most morally depraved generation thanks to our newfangled technology. The smartphones ruined people. and they behave like puppets, and even ten years ago people were more human-like in their behavior. Well no more, if the last 2 year proved anything is that technology can manipulate and control in ways that make you wish we didn't have it. But to be fair people were always very corruptable thoughout history... welcome to 1984.
I found that when cutting copper and Bronze...even though they should be cut dry... my friend (also Tool & Die Maker) showed me that squirting some Citrus Solve degreaser on the saw seriously helped with cutting! Just thought I'd let you guys know. You never stop learning.!

好功夫,讚讚讚
I've been a toolmaker for 30 years, I'm impressed. I'm a fairly good lathe hand, never thought to turn a lathe into a hob. You keep using that sandpaper tape near that chuck and you're going to lose a finger, I've seen it, my buddy had to put it in a cooler and hightail it after the ambulance. They left with him before it was found. One apprentice and the tool crib girl yakked on the concrete.
Just had an idea. For a finishing touch, you could replace the cutting tap with a rolling/forming tap and use lapping paste. Or the other gear itself if you want to match them.
I once worked in a gear shop. Using a tap to hob a gear is wild. Impressed!
Wow... !!! My best friend, Great... We liked and enjoyed to the end. Thanks Have a happy day!

9:35 How does he calculate the circumference to make sure that teeth marks overlap perfectly?
Either by trying.
Or by calculating with what diameter he always gets the same space between the teeth cuts
The tap is tapered. No such measurement exists. Also, the part as constructed has no function. Likely, they are just screwing around. Machinists don't drive bearings with a depth gauge.
@@idleobserver7211 thank you! I had the same thought.
@@Tankliker Yes, I wondered about that too!
It's not impossible, just need to get the circumference right, multiply the thread pitch by a number to give a close result as the value of the circumference. I doubt he did that however, he felt it was gonna turn out right from experience 😆.
I don't know what it is but very clever...
