Whirligig of Doom

Everybody’s favorite slingshot aficionado, Jörg Sprave, is at it again. Got an old set of steak knives sitting around the house collecting dust? Why not turn them into a battery-powered whirligig of doom? Using a battery powered drill, some MDF, and a timing belt, Jörg constructed one mean looking rotary slicer. Seems like a great stress reliever. If you get bored of the steak knives, you could always swap it out for a buffing wheel and wax your car.
