What is Standardization?Standardization is the foundation of all large-scale production. Manufacturers produce separately many copies of every part of a complicated machine to use on an assembly line. Standardization also allowed owners of machines to order and replace any broken or lost parts, taking it for granted that the new part would fit easily and precisely into the place of the old.
Eli WhitneyEli Whitney was one of the first manufacturers in the world to carry out standardization successfully in practice. Eli Whitney wrote that his objective was "to substitute correct and effective operations of machinery for that skill of the artist which is acquired only by long practice and experience," in order to make the same parts of different guns.
Eli Whitney went to Washington, taking with him ten pieces of each part of a musket. He exhibited these to the Secretary of War, as a succession of piles of different parts. Selecting indiscriminately from each of the piles, he put together ten muskets, an achievement which was looked on with amazement.
Simeon NorthSimeon North, another Connecticut mechanic and a gunmaker by trade, adopted the same system of standardization. Simeon North's first shop was at Berlin. He afterwards moved to Middletown. Like Eli Whitney, he used methods far in advance of the time. Both Eli Whitney and Simeon North helped to establish the United States Arsenals at Springfield, Massachusetts, and at Harper's Ferry, Virginia, in which their methods were adopted. Both the Whitney and North plants survived their founders. Just before the Mexican War the Whitney plant began to use steel for gun barrels, and Jefferson Davis, Colonel of the Mississippi Rifles, declared that the new guns were "the best rifles which had ever been issued to any regiment in the world." Later, when Davis became Secretary of War, he issued to the regular army the same weapon.
