Taken: May 3, 2010
Caption: 10-Inch Rodman
Additional Description: The Rodman gun featured gradual, sweeping lines, sometimes called a "continuous curve" in contemporary manuals. Rodman also used several revolutionary (for the time) casting processes. He required very precise blending of metal to meet a desired specific gravity before cooling. And after casting, cold water circulated through a tube in the bore, allowing the gun to cool from the inside out. This "pre-stressed" the gun and provided great strength to the weapon.
