The English wheel, also known as a wheeling machine in Britain, is typically a manually operated metalworking apparatus that allows a craftsman to form smooth, compound curves (or double curvature) from flat sheets of metal, such as aluminum or mild steel. It is used in coachbuilding, car restoration, hotrodding, racing car construction - (especially NASCAR spaceframe chassis racing cars that need sheet metal panels made to resemble mass production vehicles), prototype car production, low volume sports car production (especially with aluminium body panels like the AC Cobra for example), and aluminium panels in aviation. When used on thicker sheet metals such as boat or ship hulls, the machine may be powered and be much larger than the one described here.
