Another great how-it’s-made-site – “How Stuff Is Made is a visual encyclopedia that documents the manufacturing processes, labor conditions and environmental impacts involved in the production of contemporary products. It is a free, independent, academic resource published by engineering and design students, who research and produce summative photoessays describing these conditions of creation.” Thanks Star!
This week’s Cool Stuff Being Made video – heat treating! “You will see on this 18-minute video the many things that we use every day that are heat treated. As they say, heat treating puts the spring in springs. It also strengthens the metal used in axes, knives, saws, aircraft landing gears, jet engines, space ship launchers, computers, agricultural implements and oil drilling and refining equipment, to name just some. There’s also a scene toward the end that shows how many everyday things are heat treated. You see form one of the scenes the difference between a drill bit that is heat treated and one that is not. The former works while the latter fails.”
Joelsprayberry has an Instructable that’s sad, cute, funny and clever – “Our dachshund hurt his back, so for rehab we made him swim a lot and i built this chair until he could use his back legs again.”
