Pizza restaurants strive to deliver your pizza while it’s hot, but that’s not always possible. Colin Furze came up with an overengineered solution to the problem. Rather than insulating already-cooked pizzas, his Suzuki pizza delivery motorcycle has a built-in oven to cook pizzas while in transit. He built the oven from scratch using sheet metal and hydroforming.
Presumably, because his wife was sick of him tearing up their lawn, inventor Colin Furze set out to come up with a mod that lets him ride a drift trike without chewing up the grass. The trick was making lightweight, spherical “wheels” by welding together sheet metal and hydroforming them using a pressure washer.
We recently saw some unusual axes, but they didn’t include one made by inflating metal. Maker Connor Holland is back with another very cool project – a lightweight axe he created by welding pieces of sheet metal, then expanding them with air into a pillow-like axe and handle. He attached bent steel blades to give it a sharp edge.
Hydroforming is the process of shaping metal structures by inflating them with pressurized water or air. Maker Connor Holland has been experimenting with the technique, and shared this compilation of some of the more interesting and satisfying results. The pillow one looks like a metal whoopee cushion.
