There are lots of machines out there that can cut holes in flat sheets of steel, but MarkGyver built a machine that can make cuts into the curved face of a cylinder. Using a high-heat plasma cutter and a chain-driven rotating holder, the computer-controlled system can make smooth cuts through the surface of a steel tube.
After building a retractable blade lightsaber, The Hacksmith is back to show off what this impressive plasma weapon can do. Watch in awe as it burns right through a Stormtrooper, slashes through walls, and melts metal and glass like butter. It’s not as quick at cutting as the ones in the movies, but just as awesome.
