What is the manufacturing process of gear?
Gear manufacturing refers to the making of gears. Gears can be manufactured by a variety of processes, including casting, forging, extrusion, powder metallurgy, and blanking. As a general rule, however, machining is applied to achieve the final dimensions, shape and surface finish in the gear.

Been watching these videos for months. I am now convinced there is not a dial indicator in this entire country. Not taking away from what they do, it just amazes me.
Dial indicators are too fragile. If you can afford one, you have to treat it well?
When you don’t have what you need, you learn to do it without it. Home spun.
I want to learn how to do things like that. Not doing things by rote, but how to make hand tools for every purpose.
Let us return to the era of the slide rule and the tool-and-die: CAD and injection molding makes you soft.
There doesn't appear to be a lot of PPE either, not even cheap safety glasses. Their work is incredible but I don't imagine they'd get a lot in compensation if they lost an eye or two
Hell I'm still looking for a table in most of these videos. Your asking for a lot
As a 35yr Journeyman Machine Repairman , The noises that Lathe was making had me wincing and looking for my safety glasses ! And Junior on the tail stock with a pipe ! good thing he knows how to make a gear ! And that old No2 Knee Mill !!!!! Bravo to all his tooling and fixtures !!!!
Installed these on a riding mower th-cam.com/users/postUgkxetgfkJxfdT_B2vGYP-uNTLaBbim9OKTD . They were sharp out of the box, although I've never liked blade edges that were coated...not quite as sharp as I personally want. Using my belt sander, I removed the coating from the cutting edges and refined the edge enough to shave with them. So far, after three runs, these blades are holding up as expected. Even after hitting a few fallen 1/2 inch or so branches, the edges are still sharp as heck. No edge dings, no warping, etc. As far as installing them, the cutouts were of the proper size and shape to fit my aging Craftsman mower. Very satisfied.
Sir,I think if you want any endless diamond wire loop and endless diamond wire loop saw, you could contact with me any time~the machine is really cool!
Marvellous video, my late father would have loved it. He was a model engineer in his spare time, but refused to buy in steel stock or castings for his traction engines. Every thing had to be made from scrap materials and his workshop was similar to this but on a smaller scale.

They do astonishingly well with the old clapped out machinery they have to use. I was especially impressed with the high precision measuring with a tape measure.
I saw that and imediately instinctively grabbed my head
The guy moonlights as a tailor's assistant.
The machinery doesn’t look like is maintained or oiled for that matter. It’s no wonder looks and runs like junk. Just because the part looks nice I’m sure it it isn’t dimensionally accurate.
They use old machines because it is perfectly acceptable and and effective.
Anyone with training or experience can 'measure' 0.5mm confidently by eye. How stupid would you be to measure a rough diameter with a precision instrument.
@@Esuper1 haha
You know. Just got to say. If you have never tried anything like this then you have no idea all the details that go in to just learning the process let alone doing it right, better, and perfecting your skill to the best of your abilities with limited tools and technology. That's awesome great job made me smile.
A giant lathe and horizontal mill with dividing head isn't what anyone should call limited tools.
@@gussygoro2469 and I better he built it from parts or could. I'm happy for him.
Like when your last tooth comes out as a baby tooth and you check the math and you did everything correct? Then you do it again and end up with 47 perfect teeth and one baby tooth again? Only to find out their was a tiny metal chip in the dividing head throwing everything off by about a thou.... Next time Im gonna spend the $250 on a proper hob.
@@rustyshakleford5230 you good bro?

I've been a machinist for the last 32 years. This is getting it done. Respect
Well said mate, over here in the Philippines I can go to a roadside machine shop and he'll make me anything.
I bet you wear safety classes And don't put your hand around the machine
@@urielcrooks6431 you are correct.
why are their tools so crappy over there, everything looks dirty, its like they refuse to repair anything untill it completely breaks. Here in the states, we typically maintain our property and equipment. We repaint our homes when the paint is no longer good, if a door is broken we replace it. There it looks like they just hang up an out of order indefinitely sign and leave it untill one day the entire building just gets condemn.
@@mrschnider6521 This is what europeans says about US. It's like the country stayed in the 1950's...
Amazing work being turned out on old beat up machines. I began my working life in tool and die making back in the late 1970's but left the field once manufacturing began drying up here in the states. I remember cutting gears using a dividing head as is shown in the video. You did not want to be distracted cutting gears.
"What grade of steel is that?"
"Yes"
It’s called job security. They’ll be back.
yeah was wondering the same thing, considering how oxidized the starting metal was I'd say those gears will be rusted very soon. At least its pretty dry in India generally...although if these are destined for a ship...
@/k/onnoisseur oh did not know that. I suppose they can just keep them lubed up and should prolong the life

Мда, рулетка -ваще огонь. Но ничего страшного, скоро так же будем делать на таких же разъёбанных станках.
What a mass! What a big sacrifice! What a pain! What a tenacious man! I take off my hat to you brave man!👏👏👏👏👏
I commend these guys for using what they have to work with! I had to laugh though, tape measure and bit chatter.. Eeeewww that bit chatter sound gets me... Will the parts work though? Likely yes, for awhile anyway. If the gears don't have a lot of load and reversals of spin maybe a long time. I give 'em a thumbs up for doing what they gotta' do to make something run with just what they have to work with!👍👍👍
I am making a bit chatter too! th-cam.com/video/1Wm_LGoJawI/w-d-xo.html
Everything is moving, wobbling, shaking and vibrating. Very impressive results with the tooling involved. Imagine what these people could do with a little more training and some modern equipment.
they would be like we Americans..on welfare and their smart phone
All the health & safety rules would hinder their work and they’d either quit out of frustration or get sacked for continuous flouting of the rules
@@windage ngl, you had me in the first half. Lol
Charge more money for parts that are actually within tolerance.
@@magicalphones Charge more money? If parts are not within tolerance, you get no money. Clearly you lack basic knowledge on this topic.
it never ceases to amaze me what people can do with machines that are this old, i mean as long as the ways are straight and the gibs are tight thats all you need.
I once had a job doing centerless grinding on ceramic parts, and the machine i used to hold tenths on was like 50 or 60 years old and completely worn out. In fact every machine in that shop was worn out haha but we still made good parts.
A thumbs-up is truly Universal. These fellows do excellent work. It's amazing the quality that they can achieve with machines that have seen better days. Best regards Bobs from Virginia USA
As a red seal of machinist of 28 years, I find myself both appalled and amazed at same time watching this.
Watching that gear cutting setup moving back and forth a centimeter or so during the cut was interesting, you could see the wavy line of the cut going down the blanks...Also, someone needs to show them how to sharpen drills instead of just cranking harder on the tailstock handle to make it push through the metal.
ye thats what i was thinking if you need more more than what crank handle can give you your doing something wrong
Easy guys that was some tough steel they were working with there.
Cranking that handle isn't a problem when someone else does it.
There is nothing wrong with what they are doing. They make due very well. And I'm sure the price on that gear is very attractive. Probably 80 us dollars. I'm not spending 2-3 hundred for that gear if I don't have to.
Probably want to learn about lube too. 😆
I like how every commenter is a machinist for RedBull racing or the space shuttle. I have seen people making parts to get trucks, combines, or even tractors in the same kind of facilities, and stuff works. We don’t need the John Deere tech to wait 30 days for a part. Also for those bashing the guys, let’s see your videos machining stuff.

This guy works way harder than the guy running the 5 axis. I can barely cut a 2x4 straight so this guys skill is amazing to me.
@@Koru-Health i run a 90m² 5axis deckel and i've never worked that hard, hats off to these guys!
Don’t white knight something that is objectively bad practice. I’m not a machinist, but I’ve worked with metal enough to be absolutely mortified by the lack of sustainable practices and methods seen here. If you really care about these people, and by the way we all do, then you’d want them to learn correct principles and apply them to their work. The “bigotry of low expectations” causes a lot of people to ignore the obvious lack of education and/or training that millions around the world need in order to improve their lives and their country. That bigotry sees these videos, and sees the comments and thinks that the number one thing these third world people need is to be protected from criticism, and completely ignore the thing they actually need - to be told they are doing it wrong. They also need to be told how to do it right, and I’ve read many of those on this video too.
@@davidswanson5669 These specific people lack capital. They clearly do not lack skill or knowledge.
In some ways these guys keep themselves in work. The steel from an old ship is not what you need for gear wheels. Ship steel would need to be flexible while the bearing surfaces on the gear teeth need to be hardened. I admire what they accomplish with the poor resources at hand and as I say they keep themselves in business because the life of these gear wheels would be many magnitudes less than with a wheel made from the right steel, accurately machined and correctly heat treated. If these men could make gears of that standard they would get no return custom.
Loved how he changed the lathe speed. Dope! True craftmanship. Salute. 👍
My machining teacher would have a heart attack watching this video.
I have drilled a lot of holes on a lathe machine with 62mm diameter drill but never had to use a crowbar to spin the wheel on the tailstock.
Working on a machine like that with long sleeves is a suicide, its only a matter of time until tragedy happens.
ur machine teacher is a trainee in front of him
"Right for homework: Watch this video and critique every bad practice you can see. I came up with 50 when I viewed it."
I think there are over 50 continuity errors in the movie Plan 9 from Outer Space.
@@gorillaau You have to understand something here, what works over here doesn't necessarily work for them. I used to be under the illusion of following text book practices as a rule. Eventually I realized text book practices is a primer it was never meant for the real world. In the real world you have to improvise and you have to get things done on time. Some of the most skilled people are self taught and there is no technique in life that works for everyone. Everyone is different.
What's a "tolerance"?
@@Micscience " what works over here doesn't necessarily work for them"
It works exactly the the same, when the lathe chuck grabs your sleeve it will rip your hand off. Same here, same there. The difference is that you won't be allowed to work in this way in other countries.

What never ceases to amaze me in these videos is how every time someone has completed their task the end result is carried off and dumped on the ground. No matter what some poor guy has to pick it up off the ground. Someone should invent a way to store things off the ground like maybe a table or a bench.
What's funny is i come home from work, to sit down and watch other people work.....
Well done. You have mastered your craft The ability to make and sharpen your cutting tool is impressive. My Dad and his father, my grandfather, were both Tool and Die Makers and, in my retirement, I am learning the trade online, not that I plan on working as a machinist, just that I hope to better understand their profession and honor their skill and their memory. To many of us do not understand how significant the skills of the workers were 50 to 200 years ago were and how very talented and skilled they were.
I have great respect for the skilled trades and the people all over the world who work as a skilled tradesman.
These men are very skilled and I have great respect for the skill they possess.
In America today some of this work is done by programing a computer.
You either adapt or perish. Hand making these gears sure takes skill that not everyone has. Also making it via computer requires you to have skills to program the machine. Nevertheless skill is required not like any tom dick and harry can operate a machine.
My advice, don't be afraid to mess up, experiment, break tools and push limits. That's how u become the better than others. If you break this project down, the lathe work is not as complicated as it looks, it's a great learning project tbh for a beginner, covers a lot of aspects, and without lube! Really shows what you can push, though the precision here is pretty loose, you wouldn't be making very toleranced parts this way. These are big gears so it's fine. I would get sick of this part pretty quick with these tools lol. CNC so much quicker of course
If you give more importance to machines then machinery will develop.... If you give more importance to people then their skill will develop!
My father also was a tool and die maker. His face bore small burn scars from red hot flying steel chips that came from a spinning lathe. He could actually design and manufacture helicoidal gears with a precision lathe and a milling machine. Although I watched him work by his side many a time, I am sorry to state that I never asked him to teach me his skills, which included calculating tangents, curves, and angles with his knowledge and pencil and paper, not even a calculator. Those did not exist when he learned his trade. Kudos to such knowledge.
You'd be surprised. I worked in a gear shop in everett Washington that used gear hobbing machines made in the 1930s-40s. And all of the parts we made were precision gears for current production Boeing planes. The old machines last forever, however, manual machining is a dying skill in The states.
Техники безопасности совсем нет, пока я смотрел это видео очень сильно переживал за этих людей, видно это происходит или в Индии или в Пакистане, где нищета и человеческая жизнь стоит меньше чем жизнь домашнего питомца в Европе, но этим людям конечно большой респект, в таких ужасных условиях и с технологией тридцатых годов прошлого столетия они делают, создают такие детали, какая точность у этих шестерней трудно сказать, но видно есть спрос раз делают. Слов нет.
Can you imagine the things these guys could achieve with a fully furnished modern workshop?.. Awesome, True engineer craftsmen. .!
You assume that they would have even the slightest clue how to use proper tools and setup fixtures. I am pretty sure that assumption is WAAAY off.
man whole modern world did it this way maybe in early 1900´ so you are absolutely out of the reasonable think . Europe can travel to space build nuclear plants, and many else, and in this country they can made a gear from scrap. That is some serious achieve. And if you think some old grandad without proper equipment is some high valuable.... The precision of this is sadly hillarious . :D Plenty of people around the world can do the exactly same think, but why they should ?. when there is much more efficient way.

I am a beginner cnc student and I know ho difficult is to handle these manual lathes, really appreciable work 👏👏👏
You know your equipment has seen better days when everything requires a torque multiplier
I thought the same. If you need a lever to push the drill through the steel, something is wrong.....
It's just that they are not keeping their tools sharp, and they're not using cutting lubricants.
@@jameswagoner3309 Well, that and nothing is lubricated. I can't imagine how crunchy that machine must be.
It's getting the job done, and if it breaks it's simple enough to repair in shop
I was hurting when every bit of tightening required some sort of lever! They are doing it for good reason though, those machines are worn out.
The secret to precision is to always toss the parts in the dirt several times throughout the process...
And never use lubrication
haaahahaha =)
And eyeballing the part to get it centered in the chuck is fine - why bother with a dial guage?
ya'll are laughing at them. Yet, customers keep showing up at their shop.
@@CM-xr9oq because the shit they make doesn't last long
This guys are mechanical enggineers .i salute them👍🇵🇭
Absolutely beautiful work. Well done guys!
Just amazing to witness what can be made to work, using what you've been taught never to do. I'm at a loss to pick just a few favorites from this video. Near the top is whipping out a pipe wrench @10:38 to snug the mandrel. And then wielding that blacksmith's hammer @11:05 to whack the blanks true while ON the lathe. There's certainly a few good poster images in there demonstrating lathe crowbar tooling. And did I really see a guy freehand grind (just a COUPLE -- not all teeth on) a gear cutter with a bench grinder?
I cringed a couple of times, but man, freehand grind on a gear cutter and comparing the grind on an already cut gear is quite something ... I'm amazed by what they can achieve, but by no mean it is precision work ... Since it looks like a business, I thought I would have seen at least one set of cheap measuring tools like a dial indicator to whack true the gear blanks.
Without eye protection, no less.
The no eye protection had me, and Frank Roberts beat me to it!
There were only a couple of teeth that needed sharpening. On that old milling machine with the mandrels flopping around in the no-longer-bearings, the rest of the teeth never touch the part! I know this because I was cutting gears today, and with .003 runout on the cutter teeth as mounted on the arbor (I measured it with an indicator), I was only using about a third of the teeth, maybe less! We send our gear cutters out for professional resharpening, and I can measure 2.5 to 6 thou variation in tooth height from the cutter hole, depending on which cutter. I always thought it was just the arbor that is crooked, but it turns out the cutters themselves are crooked. In order to uniformly engage all the teeth at slow speed (2 ipm and maybe 1200 tpm), I would need less than a thou tooth runout and preferably less than a tenth mounted on the arbor, but these things are nowhere near that precise and most of the teeth do not touch the material at all.
@@CedricRoyblanchard The gear will wear themselves in perfect profile once the 100 HP drive beats them into meshing despite the gears objection.
There is a difference in what is obsolete and what is not. If a piece of equipment still functions after 70+ years of use then it is NOT obsolete. I smile because I worked on equipment similar to this in the 70's as a teen. Shop boy for starters and ended up working the line
yup this machinery is made strong and built to last and be worked on if needed. i'd love to get my hands on an old gisholt lathe they were made in my hometown
These guys would do well anywhere in the world , bloody impressive 👏👏👏👏👏👏👏👏
A skilled tradesman will always overcome the shortcomings of his tools. Note the lathe also appears to have a person power feed on the tail stock. Great stuff.
If a machine has an accuracy of +/- 0.015, there is no way a "tradesman" can attain an accuracy of +/- 0.005.
@@Tsamokie BINGO. You can only polish a turd so much. The good news hear is none of their inspection equipment is capable of detecting the non-conformances 🙂
I love watching these men and what they achieve, not having the benefit of modern lathes. Good luck to them and thanks for an excellent video.
Modern lathes may be out of their budget, but modern methodology and practices are free. Why skimp on that?
@@davidswanson5669 I'm gonna guess these guys don't know much exists beyond the confines of the streets where they live, work and shop. It's possible they'd adopt better techniques if they knew about them but these guys don't strike me as being especially worldly. I mean, I doubt it's due to any character fault but simply a reality of their existence and the opportunities presented to them within that world.
@@OTOss8 What you are saying is true. The internet which TH-cam is a part of is not the obvious source for information if you are not in the habit of looking. These guys are likely very replaceable. The shop owner sees any expense associated with their protection as a waste. This is probably a job to feed their kids than a vocation or identity. Amazon for a ROUGH pair of calipers would be helpful. It would be interesting to know where these parts are destined and their performance.
@@markharmon4963 I couldn't agree more with your assessment. Your question is one I've been asking myself with many of these videos. As you've said, where are these parts destined for and how will they perform given the less than strict conditions surrounding their manufacture? What type of steel is that? Has it been heat treated to the correct hardness for the application? How precise are the teeth they cut and how much of a difference does that make? I looked at those gears and I could imagine them in some sort of enormous rolling mill or something like that where absolute precision might not be required but either way it's a very interesting thing to ponder. Cheers friend.

Sent this to the Hobs department at work asking why it is taking them so long to cut gears. Looks pretty easy and wide open to me.
I laughed at this. All the time its like when do you think this run of parts will be done. I run a Gleason Phoenix GH125 hobber and a Barber Colman 16-56. Then when i have to Run a Gleason TAG 400 gear grinder its always a HOT job.

That's Pakistan for you. Making do with very little, facing immense challenges from day one and difficulty upon difficulty yet coming up with ingenious, improvised solutions. This is the true difference between the haves and the have nots. There is a reason we managed to become one of seven global nuclear powers, associate members of CERN, launched the first Asian space program and maintain an Antarctic exploration scientific presence
Nice work, maybe not high precision, but probably good for getting an other machine going again. At least the ship stock metals are directly used here. The lathe machines may be old but they work, the people operating them can fix them and resharpen the bits when required. In the Western society the waste is terrible, most equipment is obsolete within a short time, and the improvising skills have gone and we are so more reliant on computers. Great video.

Yes, there's a lot of good/ inexpensive calipers and dial indicators available on the market.
These things are not for high performance or high load machinery mate, the cost reduction of having them done like this is why they sell. They're for things like grain mills and such. They might have hashtags for gearbox and truck in there, but that's just for the viewing algorithm. All these need is a bit of oil sprinkled over them and they handle a few hundred nm or torque just fine.
@brianhoff04 the fact is you may have cringed but you could not do what they do namely make a part as cheap as possible with just enough accuracy. they do it that way for a reason mainly the cost of that part would not pay for the weeks coffee at your shop. everything has a place and a reason.

I worked in India in the 80s building a power station. With the most rudimentary equipment and zero safety a power station was built and handed over. I doubt it’s changed much. Oh, and I loved every low-tech minute of it.
Its Pakistan 🇵🇰 Mr....
@@waheedbashir1220 My apologies!
@@ianross225 thanks sir🙂
Indian here. Many things have changed now especially in Government Projects. Things like Hard hats, safety shoes, Hi-Vis jackets are needed. But on non-government projects, anything goes. If you have sometime to watch then search for "Tractor stunts India". So many people with no idea how close they came to dying/.
Nice precision cutter wobble on the mill, and especially with the worn out indexer wobbling back and forth. Amazing the guy can produce anything with the equipment he is forced to work with.
Not to mention no boring bar or reamer for the ID, or indicator for the runout when they mounted it on the shaft
But it works, and they keep all sort of equipment going, they manage to run things that we would discard, I remember well making a receiving socket made in three parts, bolted together, it had to machine both ends, when reassembling the part, two guys spent a couple of hours with bore gauges and micrometers, finally happy they said it was within 50 thousands, when the guy turned up to collect it they told him, he replied "As long as it's within 1/8 of an inch it was fine" the parts were worn out, and they needed a sloppy fit.
@@knightfall7534 right? I couldn't believe no indicator! haha oh man =\ amazing work considering the circumstances
@@ScumfuckMcDoucheface yeah for sure, but if that gear in its final assembly is going anywhere near 500 rpm’s that’s a no from me chief, especially since it’s gonna be meshing with another gear 😬
"Wobbly" could be perceived as a negative term. I suggest "Self aligning" or "servo aligning" cutting tool.
Superb and great skills 👏
This is awesome video …Appreciate your sharing😊
That is truly impressive, even sharpening their own cutting tools is a lost art in a lot of developed countries!
well if they would use a smaller drill to make a pilot hole they would not need to use so much force to drill the big diameter… and therefore the big drill would less overheat and sustain longer
We're not allowed to sharpen them ourselves. They have to be sharpened using the customers (Ford for example) precision jigs, and certified by the tool room before we can use them again.
@@Spinner1987CH Yes machine capability to get the maximum life from the tools before they can no longer be resharpened. If you only got a small number of parts from one tool, then it would push up the cost of those parts.
I learned how to do that in vo tech in the 90's. High speed steel was all we used with cold roll bc it was cheap lol.
Meh, at my job shop I can sharpen anything that's worth the time to set-up.
I respect their endeavour and good outcomes with old machine tools and cutting tools. A few observations: always wear protective glasses; use a centre drill and pilot drill prior to the larger drill; 3 jaw chucks should only be used on bright or machined bar stock. Preferably use a 4 jaw chuck for raw bar. It offers superior gripping and is just as fast when practiced; never leave the chuck key in the chuck.
First world concerns in a third world shop. Sadly, children are often seen working in these shops.
The people in this vid will never read your comment ,professor. You wrote all that for nothin.
I was wondering how far I’d have to scroll through the comments to find a mention of the 3 Jaw on that bar. Also couldn’t agree more on the glasses. I’ve been hit by hot chips many times
And contrary to popular thought a 4 jaw chuck is way more accurate then a three.
@@schizy I worked in a machine shop where that’s all we used. After some experience, it virtually as fast as using a 3 jaw.
I started on manual machines, not nice ones, just like the video.
Even though I now run very precise machines now...there was/is still what I term "eyeballin" , you learn this "feel" on a sloppy manual machine and I still employ it on very precise machines.
I thought I was good at eyeballin but these guys, yeah they are GOOD!
The gear cutter an index were both not spinning true and he still could produce that gear, very impressive these guys truly are prehistoric machinists
That mill arbor certainly has its fair share of runout in it! I’m sure arbor support bearing is hummed out too. It is amazing what they can make on machinery that is just plain shot.
Good new machines are astronomically expensive
If you are a good machinist, know the machine and how to control it. You'll be adjusting for the slack automatically.
Getting to know an abused machine, that's the real pain.
I know from experience 😂😭
@@pinocolada4254 amen brother man haha
garbage in garbage out
Runout is ok with an involute gear cutter. Cutting depth would be uniform regardless if the arbor shaft was not true.
Pra deixar uma engrenagem dessa pronta leva o dia inteiro. Muito trabalho parabéns pelo profissionalismo!
The human knowledge is the power, not the brand new technology!
Respect for these workers!
Genius! With so little machinery and tooling, it's amazing! Thumbs up!
The level of un-precision in this gear manufacturing is astonishing. But even if the cut is not optimum, it will self mesh over time and run just fine.
Un-precision, well said.
They bent that milling arbor long ago. Still straight for that short run at the root end, so they're just using that portion, probably for years.
...or melt, seize and explode 😬
Making it work!!
@@karma247ajm It all depends on the load and the speed of rotation. But i get your point.
Great work! All of you should be very proud.
Realmente el maquinado es arte. Que hace que muchas industrias puedan producir, los hermosos engranajes son un ejemplo de ello.
Don't ever use cutting oil when you're drilling with the tailstock just put a bar and wrench the darn drill into the metal. It's truly amazing what these guys get away with and still get a part that works...Sure it's not pretty but it's darn sure way cheaper than from Boston Gear!
Yeah, I'm sure the quality is crap though, which is why they're still working in a shit hole
I bet Boston Gears saturate surface of their wheels with carbon and quench them so they last for a while unlike this trash.
Oil is costly. Look at the equipment. I don't thinkbthey have the funds to spare on convienece. Iv used pipes on tail stock my self some of the big drill really require alot of pressure.
@ice50mg Not worth a work replacing them.
They didn't want to waste any of the precious used motor oil in the drilling process on the lathe, they actually need it for the milling machine which is wobbly 1cm back and forth in the indexer.
I always thought that vernier calipers being used was sign of horrible tolerance machining, but these guys whip out a tape measure! even with these tolerances though, the gears probably have chance to mesh themselves together in use eventually. I would be interested in knowing if they get hardened along the way still. OSHA inspector would probably die from stroke watching the first minute :p Commentary track from This old Tony would be great!
Oh man oh man oh man, I thought for sure I was about to watch this dude lose his arm, watching the cuff of his long sleeve dance along the surface of the chuck =/ I felt sick to my fuckin' stomach man hahaha I agree with your comment, would love to hear what T.O.T. would have to say... do you know/watch AVE? He's a fellow foul mouthed Canadian like yours truly... but he tells stories of consulting over in South East Asia and shit, where guys would take a pair of crap-tastic dollar store sunglasses and affix a sheet of cardboard around them to make a welding hood haha =\ Ugh, oh man, it would be so much funnier if it wasn't true.
Nothing wrong with using a tape or a rule when your roughing and taking a lot of material off, then switching to mics as you get somewhat near spec
Oh man oh man oh man, I thought for sure I was about to watch this dude lose his arm, watching the cuff of his long sleeve dance along the surface of the chuck =/ I felt sick to my effin' stomach man hahaha I agree with your comment, would love to hear what T.O.T. would have to say... do you know/watch AVE?

@@Liam.mitchell1 Spec in this video is a distant dream though
It’s funny because it’s true
All done manually by hand...no computerize CnC machine...they are the master of craftmanship..
Amazing. Simply amazing. This is how it was made before huge factories. Hope they have continuos supply chain to produce to. Its they rice bowl that is needed to be respected.
I was dead when he started grinding that gear cutter🤣🤣🤣
I've never seen a gear cutter, or any other profile cutter sharpened that way. I'm reluctant to say anything else.
Yeah I've never eyeballed a cutter to profile but I've never used a tape measure for precision lathe work either....
I made some big cast iron gears once. My boss hand ground an endmill to cut the teeth. It actually worked perfect much to my surprise

Excelente trabajo mis amigos, dios los bendiga siempre y felicitaciones por su trabajo..
Good Job. Thank you brother. God bless you 🙏🏼
I like how they keep their precision instruments on the floor. I know many people are more surprised about the old machinery, however, when it comes to old manual machinery....The older the better. Usually every machine shop has at least one or two old Bridgeport Mills or Browne and Sharpe Lathes. They are for when it just can't be done on the CNC, or when something breaks down because the older machines rarely break down. And, if they do, they can usually be prepared in house if need be.
At my work we have a 1960's robinson eft 36 bandsaw, a 1950's jonsereds wood planer and a 1980 or 1990's waco weinig planer. The one with most problems is the 1990's planer :D
I have a #3 and #5 W&S turret (capstan) lathes and they're great for short runs of simple parts without close tolerances. Add a Landis die head and you can make threaded parts fast.
During my apprenticeship i went thru a manual mills/lathes course and i remember one time a old friend of mine forgot to tuck in his shirt and that damn chuck nearly took him in. Shirt was all ripped and had a few scratches from catching himself, but he lived to see another day and never forgot to tuck in his shirt.
These guys are all accidents waiting to happen. Open toe shoes, no safety glasses, long sleeves, ect. They just don t tell you when one gets killed cause he was drug into a machine.
It never ceases to amaze me that nobody has invented a work bench in Asia and Africa. All the work is done on the ground in the soil.
That was one of the best uses for a tail stock I've ever seen
this was my job when i was studying in university to pay for my degree but I studied ECE (electronics and communication engineering) instead of mechanical engineering. it's very tough job. i worked on lathe machine, milling machine and shaper :) . my current job now is totally different from this kind of field. i worked now in cloud and networking security with automation for international company. my father taught me these skills. :)
its not about what their shop looked like, its what they can produce. Man that was satisfying even the working effort.
and what they produced was utter crap in every way
@@iatsd sadly youre right. But its not that crappy as you mean.
@@joshuacapones2881 I doubt they were using the right steel. The tolerances were way out for anything the gear might be used for. The machining was terrible. The finishing was close to non-existant. There was zero heat treatment, let alone hardening.
The shit they made will last less than a week before failing. It was complete crap in ever respect.
So nice to see a USA made Kearney and Trecker milling machine used to cut the gears. Nice work fellas for sure using simple methods of manufacturing.
Rest of the world has more of our milling machines than we do lol . Hell, can we even make them anymore, or did we sell off all those machines too?
@@jamesbizs We at one time had the largest milling machine maker in the world bar none. Now all we can do is just talk about the machines. The other parts of the world use them to make literally whatever they need, period. What an irony that is J P. All we can do is LOL.
Most gears in the US are made on dedicated gear cutting machines. Also use a grinder for hardened gears. Probably would have made sense to case hardened the gears so they wear slower.
@@jamesbizs America still has a huge production of machine tools, granted, with a lot of imported components. Search here for some very uplifting factory tours. Start with HASS [Surprisingly in California]. Grob, though German based makes top end machines here also.
@@guytech7310 I think this gear will be for a straw or cane chopper and not much more - sacrificial, cheap and dirty work.
What a wonderful man ♂️ I proud on these types of the all hard worker thanx by Lala Pakistani
Absolutely amazing accuracy considering the set up👋👋👋👋
You are no machinist.
I love watching people turn trash into treasure. Great video 👍👍
I wonder do you sharpen your own tools?
