Forging a Great Gun 



One of the tremendously powerful "mechanical blacksmiths" or hydraulic presses which work 

 down to smaller sizes the white hot large steel blocks or ingots. Gradually they are thus converted 

 into long cylindrical pieces, the embryo or starting point of the gun itself. These immense 

 presses are worked by levers which cause the ram in the center to obey the will of the operator. 

 Cranes and mechanical apparatus, as shown, can turn this red hot block over'and over at will
