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".

Always lovely to see these workers wearing their safety sandalls and pajamas

Glad to see that no expense is spared to ensure worker safety. Standard issue safety flip flops, I wouldn’t go near molten metal without them.

This looks like dangerous work.
Good to see most of those guys wearing safety sandals...

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.

Can critique the safety of the methods, quality and precision of the product, but these guys are doing the best they can with what they have which is often more that can be said for folks in my neck of the woods

bet these dudes can make one hell of a sand castle

[Danielrunner]

After a long day of work, I sit down crack open a beer and watch one of these videos. It reminds me how easy I actually have it.

[FourRulesRacing]

When civilization collapses I want these dudes in my corner. They can make you anything out of anything.

We do this in the US too. One guy working while everyone else stands around and watches.

"What is the metal you use?"
"The metal we have the most of!" 🙂

Suddenly I understand why "Made in Germany" lasts longer

[KRtekTM]

27:18 I like that pure smile on the guy's face when those two gears clicked together :D

[ajsindri]

with the sped up voices, I feel like I'm watching star wars

[beanabong]

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.

[rukuku]

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

machining all those teeth by eye must take ages. crazy!
