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.
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.
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.

@@jeffwood8109 What was made wasn't a worm gear. He used a screw tap that has a 60 degree angle on the thread. A worm gear has a 20 degree angle or a 14 degree 30 minute angle. He created a useless paperweight. I'm not belittling him, he's trying to pull the wool over your eyes, and obviously, did.
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.

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.
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.
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.
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 completely understand there are millions of Americans who know basically nothing about the trades and how anything in life is accomplished.

@ 7:20 he destroyed that one bearing by foolishly pounding on it like an idiot with a metal hammer. What he is supposed to do is put a block of wood between the bearing and his hammer and hit on the piece of wood. And the wood will push the bearing into place without damaging it (slowly!)
@@benjaminturpin2749 not having expensive tools to work with doesn't mean you're required to do sloppy or low quality work. Nope. It just takes a little bit more ingenuity and creativity. The job can still be done properly 👍 amen
A wood block in-between will cause the wood to compress and potentially push on the shield causing damage. He may not have installed it perfectly, but didnt hurt it at all. He only hit the races because the hammer is flat.
You should see how truck mechanics install bearings when it is a size they do not have the proper tool for. And they run millions of miles. I have never had the luxury of a race driver for wheel bearings. Because they are around 5 inches diameter they are not cheap, and many sizes are needed. 4 pound hammer and big drift and swing away.
@@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.
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.
@@billshiff2060 bill your over reacting, these people do very well with the tech they have where as you prob use computer controlled equipment and other tech etc etc but give credit where credit due I was also a lathe worker now retired.
@@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.
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.
Hats off. Yes primitive but it worked. Doesn’t mean we should approach every job in this way but we should appreciate skill and ingenuity and show our respect.
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.

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!!! 😅
Fyi it is used in some machine like single spindle automatic lathe where you engage clutch or to reverse some operation which is running if anything you found fault. Think so cause I worked in this one @@cameronmccreary4758
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.
Not back in the old days. We spoiled really bad and still make a mess of things with the tools we have now. Just remember space shuttle engines were made by hand and cant even be reproduced today.
Of course, seeing the lathe sled hit with a 2 kilogram hammer to insert a bearing reveals the high professionalism of this gentleman! Heartfelt congratulations
The final product looks great but it's not useable for anything the way it is. You could engage a worm drive into it and it will rotate and look pretty. In other words it's not finished. You must drill and tap some holes into the face so a... chain sprocket, belt drive or gear can be mounted to it for an energy drive link to something else.
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.
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.

@@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.
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 your just saying that 😄
@@gideon6331 I earn my living with metalwork. Not making garbage for click but real aircraft parts for money.
@@billshiff2060 bill your over reacting, these people do very well with the tech they have where as you prob use computer controlled equipment and other tech etc etc but give credit where credit due I was also a lathe worker now retired.
@@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.
Seriously people stop trying to brake the lathe chuck with your hand.
Very nice method with video
Hello,👏 your card was great and I enjoyed it, I am also an engineer and I follow you from Iran👍👍
Nice new idea of making worm gear,, nice
Tool could be a little bit sharper not sure of angle needed for brass ? Can be driven by a threaded bolt .
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.
IN ORDINARY MACHINE EXTRAORDINARY JOB 💯
Thanks 🤩
Very nice video. I would say this part is in bronze and for boating at first sight. Not a gear.
Capstan👍
Hats off. Yes primitive but it worked. Doesn’t mean we should approach every job in this way but we should appreciate skill and ingenuity and show our respect.
Been watching this guy's work for awhile. Always impressive.
Very beautiful 😍 🤩 👌
that is a very clever way to make such a part
Excellent work! It turned out beautifully. How about making a video for the gear that meshes with it?
There is no gear that meshes with that.
Me diste una idea para fabricar una máquina para fabricar esferas del diámetro q quiera grasias colega
Amazing technology 👏 🙌 👌 👍
It’s a TAP . Not a thread drill.
woooooow great works....thanks for video
Muito bem feita parabéns felicidades saúde paz 👍👏👏👏🇧🇷🇧🇷🇧🇷🇧🇷🇧🇷🇧🇷🇧🇷🇧🇷🇧🇷🇧🇷🇧🇷 Brasil abraço ❤
Great.... Gear hobbing on lathe..... Good idea
Interesting technique, hope he continues to retain his fingers.
Из 130мм на 80. Роствертол. Нормально. Страна багатая! Можна!!!
Thread Drill is not a machinist's term, in fact I've heard it said before.
Sen çok zeki bir insansın tebrik ederim hangi ülke orası
it's amazing work. Indian is good creator. I like your videos.
He is pakistani 😁
Lovely Work! Thank You! DaveyJO in Pennsylvania
Hola siempre veo tus videos ingenioso tus trabajos te felicito !! Jorge , Santiago de Chile .
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.
Well done fellows.. I enjoyed seeing new ways to do things.
My father used that technique more than 40 years ago to build a 300 mm diameter gear, nothing new to me this video.
@@barquisimetido1 Well there is nothing new under the sun.. what is old is new and what is new was old.. it was very interesting to me.. So glad you told us there was nothing new in this for you.. Although I can't figure out why you did..
extraordinary skill not all lathes can do it 👍👍
Absolutely any lathe is capable of this.
Rubbish🤣🤣🤣
good job👍👍
Indian machinist are cool❤🇮🇳
Los diametros interiores quedaron concentricos o es a puro ojimetro, al sujetar la pieza de nuevo pierde la concentricidad
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
Fyi it is used in some machine like single spindle automatic lathe where you engage clutch or to reverse some operation which is running if anything you found fault. Think so cause I worked in this one @@cameronmccreary4758

Thank you so much sir ❤
Awesome to watch, can even smell the different smells 🍾
Non pensavo si potesse fare col tornio bravo
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.
Wa ustad Teri ustadi ko Salam pakistani jugad 🇵🇰
I thought you were supposed to center everything before cutting. This guy looks like he just eyeballed everything
Not back in the old days. We spoiled really bad and still make a mess of things with the tools we have now.
Just remember space shuttle engines were made by hand and cant even be reproduced today.
And that's how good these guys are...
To be honest they do pretty good work for what they have

Mitutoyo would have gone broke in Pakistan
Of course, seeing the lathe sled hit with a 2 kilogram hammer to insert a bearing reveals the high professionalism of this gentleman! Heartfelt congratulations
Tosser?👎👎
The final product looks great but it's not useable for anything the way it is. You could engage a worm drive into it and it will rotate and look pretty. In other words it's not finished.
You must drill and tap some holes into the face so a... chain sprocket, belt drive or gear can be mounted to it for an energy drive link to something else.
I don't know what it is but very clever...
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.
agree
Теперь понятно кто камасутру придумал.
Mantap,hasil pekerjaan yang sangat bagus 👍👍
Nggak juga...mek copas
Nice work!
Well done without a dial gauge or micrometer in sight !
Bhi jan ya kiy cheez hy
Impressive is all I can say here...damn impressive workmanship!!
Parabéns!!! (São Paulo, Brasil para você)
"Thread Drill"....You mean a Tap...FFS....😳🙄😏🇬🇧🇬🇧
Can we use other metal mixed alloys
Parabéns! Tudo no olhômetro!
Very nice one thanku sir🌹👍❤
Fast making of bell crank hole with welding on lathe, video needed.
