Interior view of Machine Shop looking north. Boiler and truss work are on a dirt floor. In the Machine Shop metal objects were cut down to finished dimensions. The Shop contained many tools, including lathes, planers, mills, shapers, slotters, drill presses and grinders of various sizes and configurations. Some of the machine tools were immense because of the need to work on giant-sized components. Larger machines were powered through a line shaft system. A bank of six boilers and a Corliss steam engine, located in a central powerhouse, drove a series of leather belts and shafts supplying power to individual machines.
