Next, Rossiter spent months sawing, sanding, and fiberglassing the Dalek's body and dome-shaped head. To make the eyestalk move up and down, he first installed a windshield-wiper motor. Once he switched it on, though, it wouldn't stop. "The motor kept trying to move the arm [on its own]," he says. He eventually opted for a simpler servomotor, and he used another servo—linked to a wheel from an old remote-control car—to rotate the head from the inside.
