Ever heard of hydroforming? It’s a manufacturing process used to form sheet metal into shapes using water at extremely high pressures. Not something you can do at home… unless of course you’re [Colin Furze].
Hydroforming works by evenly distributing pressure via water (conveniently, in-compressible) against sheet metal inside of a mold. Many automotive parts are created in this fashion. Typical systems run at around 15,000 PSI.
After building a giant pulse jet engine (complete with butt) to fart on France, [Colin] got the idea from a YouTube comment to try to do hydroforming at home — bending the sheet metal for the giant derriere wasn’t that easy. Hydroforming on the other hand is a surprisingly simple process. Weld some sheet metal together, add a pipe fitting to connect your cheap pressure washer and boom — hydoformed metal parts.
Whoa — aren’t we missing a step here? Typical hydroforming uses a mold to push the sheet metal against in order to form a shape. [Colin's] first attempts are mold-less which limits the complexity of parts he’s able to form — although he is able to make a pretty nice conical exhaust for his souped up mobility scooter…
In the next video he promises to make something very functional out of the process so we’re excited to see what he comes up with. It might be feasible to make molds using concrete, so that may be a possibility.
Don’t forget your safety tie if you’re going to try this!
