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.
@@BrettonFerguson I complained about nails bending because they were shitty nails once. I got shown real fast that it was just because i have skill issues and someone who knows how to hammer gets it done. Maybe someone needs to show you.

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.
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.
That's also why when Chrysler outsourced the production of engine heads to India in 2001-2002, every single head failed, with some of them literally melting off the engine block.
Yeah, sometimes the cheap junk works good enough. However, this cog looks like it is going to be put into something very expensive. It also doesn't look like you can just buy 5 for the price of one and just keep easily replacing the part. The man hours to just put this piece in place might cost just as much as if they simply bought the higher quality piece to begin with. I'm not expert though.

Also you can see they don't understand how to implement more efficient production line architecture, probably because their religion doesn't allow them to learn from western society. And the safety is really bad, something tells me they have this Allah protect me mentality.
@@icykenny92 Man that is alot of assumptions there, its likely not religion or culture but poverty, outdated education, and a corrupt government that doesn't enforce regulations in their industry. You could argue that is part of the "culture" but western countries looked much like this during their early industrialization. Most likely its a developing third world country where cheap human labour is used in place of efficient but expensive machines to offset the cost.
This reminds me of American welders that act like they need a helper so they can watch eachother work. The welder isnt doing shit when the other dude is grinding and the dude thats grinding does nothing when the welder is welding.
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.
I wish all of these "experts" would gift these guys the modern tools and technology they are writing about in their critique. If not, they should keep their first world opinions to themselves. These guys do their best with what they have.
The problem is, they're selling this stuff overseas, and it gets binned the same as if it was produced with higher quality....and if they have to, they'll secretly sell it through another country if someone is trying to avoid their product, until there's literally no place a company can go to buy stuff without getting something they're trying to avoid. These are literally fraud parts once you realize how the supply chain gets peppered with these parts. A well made part and a poorly made part can mean the difference between a long lasting part or not, or a part that requires more maintenance and fuel....to the point that they actually end up costing more in energy alone than simply making the part in higher quality in the first place. It might look like a big sturdy chunk of metal, but when we're talking about machines at the scale of requiring gears this large, we're talking a lot of force that can rapidly induce wear and tear. I mean just look how easily he was able to shave off material with what was a pretty worn edge...that's some relatively soft metal. Now imagine this put into a machine with other higher quality gears that are stronger....they'll grind it up over time, creating even more wear and tear. Now imagine just the logistics of getting a replacement and putting it in when these fail. What it all means is these parts simply are less efficient and not worth it, they're like using a dirty coal powered plant for energy instead of something more modern. Everything becomes more costly in the long run. It's like if I sold you a car with an engine made out of plastic....it might run for a little while, but eventually it will melt and you'll need a whole new car much sooner than you wanted.
@@peoplez129 All industry is driven by the customer. Stop buying the cheapest thing available without asking questions, and that won't get made like that.
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.
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.
One guy with boots... spent 28 years building Arleigh Burke class destroyers. Can't imagine working conditions like these. Imagine what these guys could do with proper tooling and PPE.
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.
Right, so modern safety techniques aren't necessary, I suppose. After all, some gears were made at the same time that they used leeches to cure disease, and we all know that didn't change either.
They are still standing because of the conservation effort, not because the technology is so hi-tech. Most of the bridges from 1800s are gone or rebuilt. No bridge built in 1800s would stand today without extensive care. Did you ever heard about survivorship bias?
Impressed to no end with the exception of harvesting the metals. Looks like they are mixing iron with copper with aluminum with tin with lead etc etc, The casting will ultimately have weaknesses and be prone to failure. The whole process was incredible though.
@@PbPomper Yeah, to prevent chipping and misalignment. But if the entire tooth of the gear bends because it's alloy isn't hard enough to withstand the forces involved, the machine chugging and dragging from chips and alignment issues to get anything through is going to be the least of your worries.
I don't see any aluminum, copper or lead. They are using parts from hvac compressors, they have obviously salvaged the copper windings. Mostly plates from the stator and the outer shells. Soft steel but no other metals. I also see some insulating plastic film (probabbly polyester) which will burn into almost nothing (and probabbly be floating as light slag). Not perfect at all, but get your facts straight.
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..😢😢
With these lack of safety equipment they wouldnt be able to work very soon.

А ведь поначалу я беспокоился, что они могу попортить марку стали, если не вытащат деревяхи, мол углерода добавят, а потом посмотрел что они используют как материал. Чугунина, сталь, железо всё вперемешку. Как говорится, всё полезно что в горн полезло. Причем всё это вместе с грязью и краской. Прям отлично. Металл что надо. И это еще не припоминаю режим охлаждения. Какой он там в яме, вообще черт разберёт. Ладно еще всякие кустарные методы производства черновые сглаживаются постобработкой, но блин, для таких крупных деталей обязаны быть требования по прочности, составу стали и прочему. Я подозреваю такая деталь куда дешевле, чем произведённая как надо, но и к аварии приведёт, износится быстрее. Причем работяги трудятся в дико опасных условиях без средств защиты, лапая песок пропитанный смолой отвердевающей от СО2 голыми руками, горячая сталь рядом и тяжелые предметы, а на ногах из защиты только тапочки. Хотя, может это продукт для какой-то развивающейся экономики, которая пока не может сделать лучше, но это всё дикая дичь. Назвать эту штуквину деталью язык не поворачивается, это просто железяка в форме детали
Как тебя прёт от раздутого самомнения! Эта литейка существует давно и марка стали при той загрузке, которую тебе показали, им известна. Не считай всех, кроме себя, глупцами!

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.
As a machinist with over 40 years experience, I admire what they accomplished with what they have available, but the integrity of the metal composition is in question here. Let's hope this isn't being used on a lifting device such as a crane.
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!

as a foundry engineer, in that huge casted component, they made it pretty well and i am quite suprised. These small cracks are nothing and they are actually quite normal. Suprisingly there are quite small and not much of them. Its going to be welded anyway. But I would like to see chemical analysis of that material :D. and some ultrasound to see if there are some huge porosity inside. That would be bigger problem.

The bottle top spacers were awesome , Safety sandals are the order of the day lol . What metal are we using today answer 50 % rust , you can see the voids in the metal as it spins .
Yeah, lots of porosity in this casting. Not surprising for many reasons including the wide variety of scrap they used. You'd think they would at least us scrap sorted by metal type! It was just a pile of junk metal.
As impressed as I was with the skills exhibited, I was equally distressed at the workplace conditions and practices. I suppose as long as there are people willing to work under those conditions, they will be exploited.
European protective laws are for idiot junk workers,I'm sure about heavy automation and bureaucracy blah blah is more dangerous condition instead of personal skills and experience of these people workin g
The impurities in that metal must be astonishing. I would never want to rely on that garbage for life saving equipment. You get what you pay for in life but I'm glad someone is letting these hard working people make a living!! All the more to them.
Yeah, hopefully this thing is just going into a big tractor or something unimportant. But I have a feeling that it might go into something like a crane.
Safety squints are a must when dealing with this dangerous material. Always have your back turned to the molten metal. If you can't see it - it can't hurt you.
And now you see the glaring problem. In reality, no company would deliberately want such a part. What you are really witnessing is a counterfeit foundry that peppers supply chains with these parts. They get sent off somewhere, sanded to look like all the other better made parts from other places, and X out of 10 of those parts ends up being these. They go into some machine, break quickly, and the company is forced to replace it again....and again...and again....for a higher cost than buying a properly made part in the first place....but they can't avoid it because of how these are just snuck in with higher quality parts.
@@ESPkenner48 Because you wouldn't pair these parts with other better made parts, it would cause uneven wear and tear even on the other parts, and failures cause damage to other parts, etc. In essence, a part this poorly made is soo bad for modern machinery of this scale that it ends up costing more than just using well made parts in the first place. There is no place for parts like this in modern machinery with modern efficiency requirements. A part like this would cost more in even just fuel inefficiencies than it would cost to get a well made part. That's exactly why these parts are glaringly for counterfeit. You'll lose money by using such a part. You'll spend 10 times more in fuel than the difference in cost between this part than a better part. So from every angle these types of parts are simply obsolete for the modern age.
This video delivers and the workers did too. Excellent content. The process may not be toppity top laser cutting 23rd century tech, but it's much more understandable by the average folk and it produces what by default people picture when they read "Large Milling Machine Gear". IF the requester has more specific needs then yeah, let's get it from germany or usa or whatever. But this is the way the practical human thinks and works. Definitely much less obscure than automated processes. Besides, at one point the machine to make another machine has to be made and these dudes know how to do it. Even if there's something inherently wrong with this process (like lack of safety or excessive carbon emissions or whatever), it really helps to have at least ONE video more or less documenting it as the base from which one can appreciate more complex processes then. I feel like being shown or taught an already complex process as a young student or worker is not great if you don't get a feel of what "going in a straight line and doing exactly what was expected" is.
they cut the teeth with a shaper... holy jesus look at the surface finish.... I am terrified to know what kind of critical infrastructure this is getting placed into....

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.
If your uncle in japan can pay for it.
I wish all of these "experts" would gift these guys the modern tools and technology they are writing about in their critique. If not, they should keep their first world opinions to themselves. These guys do their best with what they have.
The problem is, they're selling this stuff overseas, and it gets binned the same as if it was produced with higher quality....and if they have to, they'll secretly sell it through another country if someone is trying to avoid their product, until there's literally no place a company can go to buy stuff without getting something they're trying to avoid. These are literally fraud parts once you realize how the supply chain gets peppered with these parts. A well made part and a poorly made part can mean the difference between a long lasting part or not, or a part that requires more maintenance and fuel....to the point that they actually end up costing more in energy alone than simply making the part in higher quality in the first place. It might look like a big sturdy chunk of metal, but when we're talking about machines at the scale of requiring gears this large, we're talking a lot of force that can rapidly induce wear and tear. I mean just look how easily he was able to shave off material with what was a pretty worn edge...that's some relatively soft metal. Now imagine this put into a machine with other higher quality gears that are stronger....they'll grind it up over time, creating even more wear and tear. Now imagine just the logistics of getting a replacement and putting it in when these fail. What it all means is these parts simply are less efficient and not worth it, they're like using a dirty coal powered plant for energy instead of something more modern. Everything becomes more costly in the long run. It's like if I sold you a car with an engine made out of plastic....it might run for a little while, but eventually it will melt and you'll need a whole new car much sooner than you wanted.

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.
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.
One guy with boots... spent 28 years building Arleigh Burke class destroyers. Can't imagine working conditions like these. Imagine what these guys could do with proper tooling and PPE.
Plenty of bridges here that were built in the 1800's using similar techniques, they are still standing. Brunel didn't have access to CNC either.
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.
Doubt it
Right, so modern safety techniques aren't necessary, I suppose. After all, some gears were made at the same time that they used leeches to cure disease, and we all know that didn't change either.
Plenty of bridges bult in the 1800's fell down too.
They are still standing because of the conservation effort, not because the technology is so hi-tech. Most of the bridges from 1800s are gone or rebuilt. No bridge built in 1800s would stand today without extensive care. Did you ever heard about survivorship bias?
machining all those teeth by eye must take ages. crazy!
I'm just dying to see an "OSHA safety inspector reacts to gear milling video" video. Please, someone, make it happen.
Impressed to no end with the exception of harvesting the metals. Looks like they are mixing iron with copper with aluminum with tin with lead etc etc, The casting will ultimately have weaknesses and be prone to failure. The whole process was incredible though.
And what about surface treatment? Surface hardness is extremely important for gears.
@@PbPomper Yeah, to prevent chipping and misalignment. But if the entire tooth of the gear bends because it's alloy isn't hard enough to withstand the forces involved, the machine chugging and dragging from chips and alignment issues to get anything through is going to be the least of your worries.
I don't see any aluminum, copper or lead. They are using parts from hvac compressors, they have obviously salvaged the copper windings. Mostly plates from the stator and the outer shells. Soft steel but no other metals. I also see some insulating plastic film (probabbly polyester) which will burn into almost nothing (and probabbly be floating as light slag). Not perfect at all, but get your facts straight.

А ведь поначалу я беспокоился, что они могу попортить марку стали, если не вытащат деревяхи, мол углерода добавят, а потом посмотрел что они используют как материал. Чугунина, сталь, железо всё вперемешку. Как говорится, всё полезно что в горн полезло. Причем всё это вместе с грязью и краской. Прям отлично. Металл что надо. И это еще не припоминаю режим охлаждения. Какой он там в яме, вообще черт разберёт. Ладно еще всякие кустарные методы производства черновые сглаживаются постобработкой, но блин, для таких крупных деталей обязаны быть требования по прочности, составу стали и прочему. Я подозреваю такая деталь куда дешевле, чем произведённая как надо, но и к аварии приведёт, износится быстрее. Причем работяги трудятся в дико опасных условиях без средств защиты, лапая песок пропитанный смолой отвердевающей от СО2 голыми руками, горячая сталь рядом и тяжелые предметы, а на ногах из защиты только тапочки.
Хотя, может это продукт для какой-то развивающейся экономики, которая пока не может сделать лучше, но это всё дикая дичь. Назвать эту штуквину деталью язык не поворачивается, это просто железяка в форме детали

You should think about times when machines were broken because someone used cheap details were made this way.
how do they control the mix/hardness and other properties of the steel if they throw random metal trash into the furnace.
application they are intended for is also random
they don't
And now you see the glaring problem. In reality, no company would deliberately want such a part. What you are really witnessing is a counterfeit foundry that peppers supply chains with these parts. They get sent off somewhere, sanded to look like all the other better made parts from other places, and X out of 10 of those parts ends up being these. They go into some machine, break quickly, and the company is forced to replace it again....and again...and again....for a higher cost than buying a properly made part in the first place....but they can't avoid it because of how these are just snuck in with higher quality parts.
@@peoplez129how do you know that?
@@ESPkenner48 Because you wouldn't pair these parts with other better made parts, it would cause uneven wear and tear even on the other parts, and failures cause damage to other parts, etc. In essence, a part this poorly made is soo bad for modern machinery of this scale that it ends up costing more than just using well made parts in the first place. There is no place for parts like this in modern machinery with modern efficiency requirements. A part like this would cost more in even just fuel inefficiencies than it would cost to get a well made part. That's exactly why these parts are glaringly for counterfeit. You'll lose money by using such a part. You'll spend 10 times more in fuel than the difference in cost between this part than a better part.

Besides, at one point the machine to make another machine has to be made and these dudes know how to do it.
Even if there's something inherently wrong with this process (like lack of safety or excessive carbon emissions or whatever), it really helps to have at least ONE video more or less documenting it as the base from which one can appreciate more complex processes then.
I feel like being shown or taught an already complex process as a young student or worker is not great if you don't get a feel of what "going in a straight line and doing exactly what was expected" is.
