The Double-acting Press

This is the giant double-acting press that was built at a cost of around 125,000 1951 dollars with the aim of synthesizing diamonds.  The behemoth was built in Birdsboro, Pa. and its construction took nearly two years.  The two rams were eventually tied together to give it the capability of delivering 1000 tons of force.

This is the press identified in GE press releases as the one on which diamonds were first made.  The Watson-Stillman press on which diamonds were in fact first synthesized is visible in the lower left-hand side of the picture.  Notice the wet weather gear hanging just to the right of that press which was necessitated by the many leaks in the ancient system.
