The radio telescope is mounted on circular rails. The tilt mechanism (best seen at the bottom of the middle arcs in the first picture) were taken from the 15-inch gun turrets of dismantled battleships Royal Sovereign and Revenge. The entire structure was built by Sheffield bridge engineers. Apparently the problems of budget blow-out were soon forgotten when Jodrell Bank intercepted the radio echo of the Ballistic missile that the Soviets used to put Sputnik into space.
