For the steamies out there. How it was really done.
Here’s a fascinating look at high-tech manufacturing in the 1930’s. This week’s Retrotechtacular features the building of a steam-powered locomotive. The quality of the black and white footage, and the audio accompanying it are almost as impressive as the subject material — which is nothing short of a machinist’s wet-dream but also includes much forging and smithing.
