Your steel mark will be "whatever we had in the scrap heap that day", and heat treatment will be "very good", with carbon content of "dont worry about it", tolerances of "very good" and surface finish of "real smooth".
Yes. However this is also true for 90% of things bought in the United States these days. Nylon and Polyacetal gears are more durable than "steel" gears made in China. Everything has "Made in China" printed on it. Everything "steel" is made out of recycled printers, refrigerators, and crap. Every made from "steel" likely had a decent percentage of copper, nickle, and other metals. This is why half the office chairs in the USA, the adjustable bolt in the back has stripped threads and almost every chair doesn't work properly. This is why if you try to hammer a nail into hard wood, it will bend. The nails available will barely go into farmed pine. You need a pneumatic nail gun. If you try to drive them in with a hammer and don't get it the first whack, it will bend. It isn't just nails. All hardware is like this. All appliances are like this, microwaves, fans, ovens, washing machines, anything made overseas. Fortunately most important western automotive drive-train, engine and transmission parts, are not made in China yet. Otherwise our engines would explode after 25,000 miles.
Have to wonder what the injury % is and life expectancy of these poor workers. No safety glasses and wearing sandals in dangerous working conditions. Have to admire their work ethic.
Because it's what you call hardworking no looking fancy in colourful clothing that's why they get the job done and for next to nothing pay compared to western living is why companies are hiring such people! And moving over to 3rd world countries...yes
Gears like this are used for bridge mechanisms and such. They don't turn fast, never get a lot of revolutions, and the surface finish will lap in with wear. There are 150 year old mills with gears made in this fashion that are still working.
Saftey is there last concern or worry, they got kids at home to feed, cloth. dont be a prick. if you have even low IQ, you can tell these men are poor. from Pakistan.
To be fair, if that shit falls on your steel toe boot, or your sandal shod foot, you’ll be losing that foot either way. That being said, it is dumb for 1 million more reasons.
You would be surprised how much of a science iron making already was in that time. The products made in the 1800s were of much higher quality than what is done here. Brunel would be embarrassed that 220 years later these people lack the accuracy people expected then.
For those wondering about the gas step: Gas-cured (“Cold box”). Sand and a gas-reactive resin system based upon phenolic urethanes, acrylics, or sodium silicates; gases include amines (TEA/DMEA), SO2, and CO2. Sand is first mixed with the gas-reactive resin system and deposited into a core box. The mixture is instantly hardened by blowing a specific gas through the core box; thus working time is flexible as it is a function of the delay between molding and gassing. The mold can be used immediately for casting. Sand is removed either by physical methods (shaking/rapping) or via thermal operations that pyrolize the binder.
Ive watched similiar videos of these guys repairing tractor tires...grinding down the rubber, heating and melting it, actually ' sewing ' metal wire around the patch and putting and actual new rubber cast mold into the damaged spot....it comes out new. Comments from American tire experts are astounded at these peoples ingenuity. My dad used to do this sort of thing on his farm in the late 40' into the 1950's. You work with what you have and you make it work....again, like one person said " they wouldn't have a system of making these parts unless they did work and people kept coming back for more " right ? I'll put it to you this way....hands down....if i became rich and wanted something very rare and impossible to find an orignal example of made of metal - i would go to Pakistan and ask these guys to build it. Seriously. I'm into model tanks and planes....the German Tiger 1 tank ? Extremely rare. 7 complete examples left in the world...1 running. Some private collectors are reduced to piecing one together from various old parts called ' Frankentigers ' they dont even have an engine. The amount of money that a German, American or high tech Asian country would charge to build a brand new replica of a Tiger 1 ? Probably twenty million USD. Pakistan ? Maybe 2 million. Im just saying....its the truth....and it would run and work.
The difference is pretty obvious when you see the same guys coming back to get the same repairs week after week on the same machines when the US versions last years longer and require much less maintenance. They do it this way because they have no choice, not because it's just as good and they don't have the money to upgrade or some other goofy reasoning.
There's also a matter of scale, the average American farm is 173 hectares, average Pakistani farm is 3. If a farmer in Nebraska doesn't slap a new tire on as quickly as possible and get back out in the fields they can lose more yield from the delay than the total production of the entire Pakistani farm.
All these people in the comments being impressed at the “skill” with which people make “industrial” gears using “primitive” tools and techniques. All I see is exploited people working in dangerous conditions to create objects of poor quality that only superficially resemble the thing that is actually needed by society. I sure hope these gears aren’t being used for anything important, since they’re made of random, highly-contaminated metal scrap to tolerances so large it defies justification. I don’t know how many workers are seriously injured each year making these things, but I’m sure even more innocent people will suffer as a result of the gears being installed into machinery that subsequently fails with unpredictable consequences.
If you saw where 80% of pharmaceuticals that come into America from India you'd lose faith in our country. We love cheap exploited products. Your shoes were probably made by child slaves.

This is pretty interesting...it's like looking back 150 years or so to the days before mass production and automated machinery, when everything was made more or less by hand.
wow, on the one hand fascinating, on the other hand I feel like traveling back in time with Friedrich Engels to the condition of the working class in Manchester in the 19th century.
This is why western-manufactured parts are more expensive: They use the proper grade of materials, are finished to the specified tolerances and workers are equipped with the proper protective gear.
Looks like a lot of steps are mostly for job creation, government grant perhaps?.. Some people jobs at the mould construction stage seem to be "I spread baking soda where it doesn't matter".
@@peoplez129 It's durable because it's way bigger than what would otherwise be needed if it was tightly graded and controlled. To compensate for exactly that. Same as how when people made bridges out of stone, they made them much heavier than modern steel ones. And they still stood up, because overengineering can make up for a lack of materials for most tasks that need brute strength not super precision.

That's a broad conclusion as there are huge numbers of manufacturers and large ones which produce high quality parts. Still I wonder how useful these particular parts really are as they apparently contain significant defects.

This is just very old tech. We have learnt so much about the physical process since. There are loads of different compositions, which unique characteristics, heat treatments, surface treatments, etc... Create high performance metal parts is a like being a chef. You need to follow the recips, master the skills and understand the process. These guys are more like fast food or road kill chef. Just grab whaever you can find and make something that LOOKS like a giant sprocket.
@@PbPomper Yeah, I basically agree with that. I understand what you're saying, but -that is also how I can tell that you're not getting my point. I mean, you don't see chimpazees just grabbing whatever they can find and make something that looks like a giant sprocket. You don't even see chimpanzee appearing able to or even _interested_ in grasping even the concept of a sprocket, what makes that a thing. So yeah. Refining methods over and over, incorporating new techs and materials as they become available to refine some more. Those are what seprates the microchip from the sledgehammer. Literally.
Once upon a time in Germany they realized they were a backward bunch of hicks and sent guys to England to figure out how things were done there. 19thC. Forget the specifics.

The Jawa's from Tatooine! Now I know where they come from! Nah just kidding, anyway, metallurgy was still not invented when this video was made. For a gear which needs a specific hardness and heat treatment it seems odd to just use the family cutlery to fabricate it.
Здорово конечно что они всё это делают, но покажите как все эти детали работают, многое сырое и не точное, покажите сколько эти детали служат. Для контента конечно хорошо, вот для работы сомневаюсь.
We use to to do this sort of work in New Zealand in the 70s when i started work. All those foundries are gone now. I must admit, our working conditions and safety where a lot better than what these men work in. Patterns and mould making much the same. All the old lathe factories are all gone now too, maybe the odd one around. The lathe factories we have now are all computerised.
I agree - this is probably in Afghanistan or Pakistan, going by their dress. And safety of course is non-existant. But kudos to the chaps for their can-do jugad!
Where abouts mate? I did ten years at Bradken as a molder and eventually part of the cast crew too as a pourer then mainly on the crane.90% of it was molding though.it was a tough job but at least it kept me fit.
thanks for the fantastic video! in the future could you either speed up the video without pitching the sound up? it’s usually a setting for the audio. otherwise, if you could just post the full video and let us speed it up in youtube if we want to.
It looked like they were throwing random scrap into the blast furnace. I don't understand how they're controlling the quality of the steel. Mad respect in any case, they clearly have manufacturing skills. OSHA would have a heart attack if they came into that shop tho LOL!
OSHA would have a field day in most American business too are a joke. Tis why not much built in the u.s. too & we know fat cat Americans want it made cheap so they line their pockets at human cost NP
The material (steel) that is thrown into the huge furnace could easily take a life or create a illness that could end life as well…. The end result is a very discutabel cog of an unknown steel variant that can never be as strong or as hard as been given for such an end result. I’m stunned things like this still happen!!
Even if ppl like to moan about the quality of the product, I always like when ppl are working hard to use what they have in hand. And I believe they know suitable applications for the products where it doesn't endanger anyone. Hopefully.
I'm going to throw this out there; if this were a series of photographic plates of a bunch of blokes with flat caps and overalls in a mill town somewhere outside Liverpool doing sand casting in 1860, we'd all be amazed what they were able to do with such simple equipment. And that gear would go into an ironclad battleship's guts and not leave until the scrapyard cut it out. I think we underestimate the value of 'good enough' in building the next, more perfect generation of machines.
Not even that long ago. I used to work in an engineering company back in the 80s with no health and safety or guards on the machines over here in Yorkshire. It was great. A lot of people think everything comes out of a clean room made by robots and 3D printers.
Relaxing video to watch, thou would like to see the gear in function where-ever it is intended. Trusting it'll do a good enough job on par with the rest of the machinery.
when people like Joe Rogan say that "aliens made the pyramids" because "who the hell can do that kind of work without laser cutting and precision tools" and everyone who never seen a machine bein made agrees with him. These are the kind of guys could LOL!
Standards exist for a reason. Those blokes in 1860 would have made a death trap mechanism that suddenly fails and kills 100 miners or whatnot. "Good enough" is absolutely horrendous. You have to follow engineering tolerances, so unless this gear is going into something very simple, It's a disaster waiting to happen.
It's really interesting to watch such a large cast made by hand, but it also gets to me when I think about how much danger these guys are expected to put themselves in for their bosses.
Similar risks are evident daily in industry right here in the US. OSHA is undermanned and generally incompetant. People get seriously injured and killed very frequently in American industry.
@@nitromartini1422 You are absolutely correct, and employers more often than not "imply" shortcuts by having unreasonable timeframes. Last place I worked (one of the largest employers in America), the policy demanded basic safety procedure like buddy lifting, ladders/carts to get high items, carrying only one item at a time... But doing it the way they DEMANDED, nobody could get their duties done in time, and that's just something that was absolutely unacceptable to regional and project managers, it would always result in write ups. I mean even if state shows up to investigate, the bosses would just blame the workers for not following the "instructed" procedure and just terminate them. It's just a sick and exploitative system, a lot of us sacrifice our health and longevity simply for a marginal increase in corporate profits (i.e. to buy a few CEOs a new yacht and vacation homes).
My great respect for these workers whos got up early morning and work hardly for a piece of bread and a dish of rice,to ensure a better future for his sons and daughters..😢😢

This is pretty interesting...it's like looking back 150 years or so to the days before mass production and automated machinery, when everything was made more or less by hand.
Most of the world lives like this still. Not every region of every nation is like America mam
meanwhile in 2023: made in china, no factories here!
Maybe more : )
Despite the conditions in the Video, the process itself hasnt changed very much.
@@mi5iu491 you need to get out more, what America has to do with it ? They didnt invented it and they do not have the highest living standart either
with the sped up voices, I feel like I'm watching star wars
Jawa’s !😂
wow, on the one hand fascinating, on the other hand I feel like traveling back in time with Friedrich Engels to the condition of the working class in Manchester in the 19th century.
This is why western-manufactured parts are more expensive: They use the proper grade of materials, are finished to the specified tolerances and workers are equipped with the proper protective gear.
Whats more impressive to me is the fact they have a milling machine large enough to face this part
Looks like a lot of steps are mostly for job creation, government grant perhaps?.. Some people jobs at the mould construction stage seem to be "I spread baking soda where it doesn't matter".
Lathe.
@@ItsMrAssholeToYou Good catch Asshole, that would be a vertical lathe, not a mill.
You don't need a good mill when the part is made of a bunch of scrap metal. It's a big part, it's metal....but it's not durable.
@@peoplez129 It's durable because it's way bigger than what would otherwise be needed if it was tightly graded and controlled. To compensate for exactly that. Same as how when people made bridges out of stone, they made them much heavier than modern steel ones. And they still stood up, because overengineering can make up for a lack of materials for most tasks that need brute strength not super precision.
This is like taking a step back in time to the 18th/19th century through a modern colour window 👍
I was thinking the same. The process is quite correct in most of manufacturing steps. But they make it like in 18/19s.
Exactly. When you have enough free time and manpower you can do it that way
Health and safety have yet to be invented...
Ya it must be 18 19th century old technology but it is inexpensive way to make things work this is d reason world is running in balance right 😊
@@porkey768 Typical managment talk. That is not the "inexpensive way to make things". At this point of time in humankind history this is the stupid way to make things.
Glad to see that they have those safety sandals.
Good to see everyone is thinking about safety first.
These skilled guys are keeping stuff affordable.
And dangerous
@@A_Stereotypical_Guy I was going to say the EXACT thing!!! And dangerous.
@@A_Stereotypical_Guy Okay when was the last time you donated extra beyond the cost of the stuff you order to buy PPE for the workers? What's that, never? Huh weird.
@@gavinjenkins899 there should be a margin in their profit for PPE. Besides, most PPE can be homemade.
There's probably a few very low cost procedures and equipment upgrade that can help with safety greatly.

That's a broad conclusion as there are huge numbers of manufacturers and large ones which produce high quality parts. Still I wonder how useful these particular parts really are as they apparently contain significant defects.

This make me believe in humanity. Human ingenuity at it's finest.
This is just very old tech. We have learnt so much about the physical process since. There are loads of different compositions, which unique characteristics, heat treatments, surface treatments, etc... Create high performance metal parts is a like being a chef. You need to follow the recips, master the skills and understand the process. These guys are more like fast food or road kill chef. Just grab whaever you can find and make something that LOOKS like a giant sprocket.
@@PbPomper Yeah, I basically agree with that. I understand what you're saying, but -that is also how I can tell that you're not getting my point. I mean, you don't see chimpazees just grabbing whatever they can find and make something that looks like a giant sprocket. You don't even see chimpanzee appearing able to or even _interested_ in grasping even the concept of a sprocket, what makes that a thing.
So yeah. Refining methods over and over, incorporating new techs and materials as they become available to refine some more. Those are what seprates the microchip from the sledgehammer. Literally.
Suddenly I understand why "Made in Germany" lasts longer
What a dope. Why are you comparing poor people with billion dollar companies. Toyota outlast any European shite.
Once upon a time in Germany they realized they were a backward bunch of hicks and sent guys to England to figure out how things were done there. 19thC. Forget the specifics.
Here, www.dcs.k12.oh.us/site/handlers/filedownload.ashx?moduleinstanceid=1974&dataid=3828&FileName=Ch_9_Sect_3.pdf page 298 talks a little about it.
23:18 good to see they are wearing the proper safety sandals while handing molten metal.
They dont need any labor safety, instead they have 250 millions of people in Paki and 1.6 billions in India. Plenty of labor source.
☠️
Just as important as the safety squints when cutting with an oxy-acetylene torch
not to mention the safety children walking around
cheap labour power loves safety sandals
I worked for this company years ago. We always made the joke of throwing molten steel down their backs with the rookies. It was very funny!.
wow npaka galing ng ginagaw nyo,manu manu,grabi galing nyo mga idol
The Jawa's from Tatooine! Now I know where they come from! Nah just kidding, anyway, metallurgy was still not invented when this video was made. For a gear which needs a specific hardness and heat treatment it seems odd to just use the family cutlery to fabricate it.
It looks more like playground than production factory 😂😂😂
Yes. I will make this couple ton gear in sandals. Np.
Здорово конечно что они всё это делают, но покажите как все эти детали работают, многое сырое и не точное, покажите сколько эти детали служат. Для контента конечно хорошо, вот для работы сомневаюсь.
We use to to do this sort of work in New Zealand in the 70s when i started work. All those foundries are gone now. I must admit, our working conditions and safety where a lot better than what these men work in. Patterns and mould making much the same. All the old lathe factories are all gone now too, maybe the odd one around. The lathe factories we have now are all computerised.
I agree - this is probably in Afghanistan or Pakistan, going by their dress. And safety of course is non-existant. But kudos to the chaps for their can-do jugad!

thanks for the fantastic video! in the future could you either speed up the video without pitching the sound up? it’s usually a setting for the audio. otherwise, if you could just post the full video and let us speed it up in youtube if we want to.
It looked like they were throwing random scrap into the blast furnace. I don't understand how they're controlling the quality of the steel. Mad respect in any case, they clearly have manufacturing skills. OSHA would have a heart attack if they came into that shop tho LOL!
OSHA would have a field day in most American business too are a joke. Tis why not much built in the u.s. too & we know fat cat Americans want it made cheap so they line their pockets at human cost NP
"I don't understand how they're controlling the quality of the steel."
LOL. They don't, simple as that 🤣
😂😂😂😂😂😂😂😂 it's "Good enough" quality@@damianboj3809
There is so much steel there, if you approximately know what kinds of scrap you put you can be relatively close to your desired composition.
At the end, they throw a wheelbarrow with flip-flops
Its like a Jawa factory along with the voices.
The material (steel) that is thrown into the huge furnace could easily take a life or create a illness that could end life as well….
The end result is a very discutabel cog of an unknown steel variant that can never be as strong or as hard as been given for such an end result. I’m stunned things like this still happen!!
NASA spent millions making a pen that could work in zero gravity. The Russians just used a pencil.

Child labor is not wasted here. I'm glad they are all wearing safety sandals.

And Safety Squints
Even if ppl like to moan about the quality of the product, I always like when ppl are working hard to use what they have in hand. And I believe they know suitable applications for the products where it doesn't endanger anyone. Hopefully.
So this is what the minions were based on

Why do you need so much metal processing when you can use “precision casting”. In general, of course, this is the Stone Age.
I'm going to throw this out there; if this were a series of photographic plates of a bunch of blokes with flat caps and overalls in a mill town somewhere outside Liverpool doing sand casting in 1860, we'd all be amazed what they were able to do with such simple equipment. And that gear would go into an ironclad battleship's guts and not leave until the scrapyard cut it out. I think we underestimate the value of 'good enough' in building the next, more perfect generation of machines.
Not even that long ago. I used to work in an engineering company back in the 80s with no health and safety or guards on the machines over here in Yorkshire. It was great. A lot of people think everything comes out of a clean room made by robots and 3D printers.
Relaxing video to watch, thou would like to see the gear in function where-ever it is intended. Trusting it'll do a good enough job on par with the rest of the machinery.
when people like Joe Rogan say that "aliens made the pyramids" because "who the hell can do that kind of work without laser cutting and precision tools" and everyone who never seen a machine bein made agrees with him. These are the kind of guys could LOL!
Standards exist for a reason. Those blokes in 1860 would have made a death trap mechanism that suddenly fails and kills 100 miners or whatnot.
"Good enough" is absolutely horrendous. You have to follow engineering tolerances, so unless this gear is going into something very simple, It's a disaster waiting to happen.
@@Avaruusmurkku Why are you assuming it isn't going into something it is perfectly suitable for?
I wonder how many cutting bits they go through on that lathe since they're not using any coolant.
They were using coolant you didn't see that fan next to the machine 😂😂😂
Если свойства полученного металла в изделии не важны, то можно и так... Зубья поотваливаются, новую сделают. Главное, что бы процесс шел!
It's really interesting to watch such a large cast made by hand, but it also gets to me when I think about how much danger these guys are expected to put themselves in for their bosses.
yep. and all the bootlickers making excuses in the comments, as if were living in the 30s
Similar risks are evident daily in industry right here in the US. OSHA is undermanned and generally incompetant. People get seriously injured and killed very frequently in American industry.
I was scared for them the whole time watching this.
@@nitromartini1422 You are absolutely correct, and employers more often than not "imply" shortcuts by having unreasonable timeframes. Last place I worked (one of the largest employers in America), the policy demanded basic safety procedure like buddy lifting, ladders/carts to get high items, carrying only one item at a time... But doing it the way they DEMANDED, nobody could get their duties done in time, and that's just something that was absolutely unacceptable to regional and project managers, it would always result in write ups.
I mean even if state shows up to investigate, the bosses would just blame the workers for not following the "instructed" procedure and just terminate them.
It's just a sick and exploitative system, a lot of us sacrifice our health and longevity simply for a marginal increase in corporate profits (i.e. to buy a few CEOs a new yacht and vacation homes).
It is a little further on than the Industrial revolution, manual labor, child labor, dangerous labor and yet, here we are...
Looks like their tolerances are in inches.
