Interesting WWII Manufacturing Video
Chrysler was given task of taking the hand-fit 40mm Bofors
anti-aircraft gun and mass producing it for WWII. They gave each division a main part and used over 1,000 sub-contractors for the small parts. Drawings were translated from Swedish so the shopmen could read them. I imagine the entire process took months so our ships could be better protected for the war. One aircraft carrier shot down 32 Japanese planes in under half an hour with these things. Thinking back to my yout, I called these "pom-pom guns". http://tinyurl.com/y9o6m25b -- Self-development is a higher duty than self-sacrifice. -- Elizabeth Cady Stanton |
