We love how metal can be used over and over again. After one object has served out its life, it can often be melted down and turned into something new. In this clip by metalsmith Random Hands, he shows us how he took a rusty link from an old piece of ship’s chain and hand-forged it into a beautiful new samurai sword.
Think of how strong a steel chain can be. Then imagine the forces that must be necessary to shape and connect its links. In this video from Engineering and Architecture, we get an up-close look at a specialized machine that takes lengths of steel wire, then scores, cuts, bends, and presses the pieces together.
Works by Solo’s fidget toy is handmade from 26 components, including bike chain, custom-cut sprockets, and bearings to create a unique metal plaything. Its two gears can rotate independently, and move smoothly so you can get some speed going. See how it works and how the design came together in the video clip.
