Precisely So (1937) Manufacturing Tolerances

[@kyouhyung]

When a pre WW2 ad turns out to be more entertaining and educational than many modern videos.

[@3rdGenGuy]

most of these videos were made to train people (mainly women in ww2) who had never worked in the manufacturing sector before. they had to get the point across clearly and as fast as possible. the result is a good video. I make how-to videos and I've taken many notes from these.

[@IronClad292]

Measuring is what I do for a living, and the tools you see in this video are still in use today as well as computer controlled CMM measuring machines, which I program. When you watch this video, please consider how just a few years earlier people were getting around using horses!! The technology developed fast........

IronClad292 The thought and origins of the measuring technology is very interesting.

[@ogarnogin5160]

It took a few centuries to get that far , They were making steam engines in the early 1700's That means they had some precision capabilities in at the least the late 1600's Most then were comparative readings , with calipers etc

[@paulbroderick8438]

It was the introduction of Statistical Process Control, a departure from the old GO/NO GO gauging system, which really controlled resultant measurements. Prior to SPC, a hole on top limit could lead to a 'loose' fit when matched with a shaft on bottom limit. Used SPC methods covering various critical components in production engineering.

This is a chronicle of the "American System" of manufacturing that was pioneered by Eli Whitney and his system of interchangeable parts whose sizes were qualified by master gages. That system was perfected by the gun industry of Connecticut through the 1800's and transferred to the auto industry when GM hired Henry Leland to be chief engineer at Cadillac. If you walk through an inspection department at any manufacturing or engineering facility today, you can still see Rockwell hardness testers, precision dial indicators, and go/no-go gages. This is the bedrock on which America's industrial strength was built. By this system, auto manufacturers were able to build cars at low enough cost that anybody could afford to buy them.

[@MrShobar]

Andy Harman The master standard is still the gage block, shown in the film. One step removed from the uniform system of weights and measures maintained by the federal government, also shown in the film.

[@ogarnogin5160]

They were mass producing things before Eli was born , He did not prefect mass production , Exampled ... rail road wheels and English ship hardware etc He never filled his 1st order for 10,000 guns because of quality control problems, H e had a more advanced concept , but it needed work .

There are so many things to say about this beautiful 1937 series of videos that I don't know where even to start. The tools to create the videos themselves weren't very advanced, yet you see cute marching tools at the end. Someone had to think of that. And if one transcribed the narration, it would forrm beautiful, proper writing. Then there's the perfect elocution of the narrator. And then, of course, the excellent educational subject of the recordings. Who would not be proud to have lived and contributed to that era. One can imagine families gathering around their TV sets or radios to see / hear one of these episodes. They are high quality productions, each beginning with a little story to inspire why the subject matters at all. They never insult your intelligence. And finally, the feats of technology themselves (i.e. the subjects of the recordings): Brilliant! All of these foundational things and pride in them have been lost. (._.) Thank you for these videos uploader. ❤️😊🙂

[@seacoast6351]

They say cars have improved since the 30s and Im sure in many respects that is true.

Nowadays Kids think the earth is flat and have no idea how anything works.

Uh... no You’ve obviously never seen Mustard. And it’s not the best effort by a multi-billion dollar company either.. it runs on sponsorship and donations. What’s interesting is... we know more about the time you lived through than you do.. and can spot your bullshit from a mile away. That’s why companies like GM don’t make this anymore. We know that back then they made these to pretend they cared abort the customer. Only a decade earlier, they’d introduced planned obsolescence to fleece their customers of their hard earned cash. Today? The average car in North America is 11 years old because nobody can afford to buy new. They made them well because Consumer Reports and social media will absolutely destroy any substandard quality. And when the profits don’t line up... the car executives spend money where it matters most-in Washington.

[@firemanjim324]

In his later days , my grandfather was a security guard at a chemical fertilizer company. I used to go to work with him at night , and we rode around on the golf Cart to go check the buildings and offices. One night , he took me into a huge room , in the main building/office , and it had a scale inside a glass/steel cabinet. It had tubes coming out of it , and some rubber gloves attached to the doors so you could do stuff with the scale , in a controlled environment. My grandfather said it was one of the most accurate scales in the state and that other companies and even state and federal businesses sent stuff there to get weighed/ tested. As a 10 year old, that was one of the coolest things I had ever seen......

I drove a '48 Chevy for quite some time. It had the 235 Cubic Inch 6. The engine had no oil pump, but got oil from little cups on the bottom of the crankshaft. It worked well with the lower speeds at the time it was built, but as speeds increased, the engine couldn't get enough oil to the engine. In '52, Chevy changed the engine to a more modern oil delivery system.

I find it interesting that, even though there were proportionally more people involved in manufacturing, the need for this film shows that there was still a great deal of popular ignorance of practical science, much less theory. One may argue that scientists like Einstein were more renowned then, but I dare say few truly understood their work, just like today. While we may moan over our education system today, the ability to distribute and access this information is much better.

These were all part of GM's 'mass-selling' technique (there's actually a GM dealer training video on KZbin which explains it). This films would have been shown in movie theaters, schools, factories and workplaces as genuinely educational short features but they more subtly emphasised all the good qualities of a Chevy and built up the public perception of the cars. So the film about the differential gear is a very good way of explaining why the diff is needed, how it works and what effect it has but makes sure to end by pointing out that the new GM hypoid differential is the best ever and because of it the '37 Chevrolet has a flat cabin floor, or whatever.
