Description

140 Foot Telescope construction - the 17.5 foot diameter spherical bearing leaving General Steel Industries at Eddystone PA, where it was cast in early 1963. With a weight of more than 350 tons, it was the largest nickel steel casting ever poured. Much of the material was cut away in subsequent machining. A special railroad car was cast in a single piece to transport it from the foundry to the Westinghouse plant at East Pittsburgh where it was machined.
