First, wear your dust mask. Who knows where these machines have been?
Yeh, it’s crazy right?
This is all just fancy wheels, turned around, odd shaped, made to fit together better.
And the understanding of mathematics, geometry and mechanics makes this massive apparatus of intricately connected pieces - which are relatively easy to understand in isolation - into this thing that can point a gun to be able to hit a moving target.
World War 2 was horrendous. But some of the tech developed is jaw-dropping.
Since then, it’s grown exponentially. We are standing on the shoulders of giants!
The craziest thing to me is they didn’t have any sort of CAD, 3d printing or other rapid prototyping tech. Most of these things wouldn’t work if made from a cheap sample material either, due to the torque they needed to handle. So really the only option was to put a ton of effort into design, make a few prototypes and start manufacturing. Iterative design could take years to get results back from users.
The classic example to me is the square bale knotter. A collection of cast iron sector gears, cams, jackshafts, blades and hooks with grippers, flung through their complex cycle in 1/4 second in dirty field conditions. Using arbitrary twine and tension, variable drive speed and a product that can vary from 10lbs to 80lbs per volume. For tens of thousands of cycles with minimal maintenance aside from pumping grease into the grease points.
And mine is still working perfectly today after 60 years or more! This year it didn’t miss one single knot of thousands. Incredible engineering.
Oh yeh, things like old looms? That ran on punch cards to program the pattern? https://en.wikipedia.org/wiki/Jacquard_machine
First prototyped in 15th century.
And all the iterations on it in the 18th and 19th century. Very cool tech

Good point. I run a lot of old equipment and compared to what new stuff could handle, I absolutely abuse it.
My flatbed “1-ton” F350 used to be a grain truck. 1 ton of grain wouldn’t even fill half the box.
I can put 4 round bales on the deck, well over 2 tons, and the overload spring pack isn’t even touching the mounts yet. It was overbuilt, all right.
