Henry Ford's Model T and the Assembly Line in the 1920s


Henry Ford, My Life and Work (1922)

A Ford car contains about five thousand parts—that is counting screws, nuts, and all. Some of the parts are fairly bulky and others are almost the size of watch parts. In our first assembling we simply started to put a car together at a spot on the floor and workmen brought to it the parts as they were needed in exactly the same way that one builds a house….. 

The undirected worker spends more of his time walking about for materials and tools than he does in working; he gets small pay because [walking] is not a highly paid line. The first step forward in assembly came when we began taking the work to the men instead of the men to the work. We now have two general principles in all operations—that a man shall never have to take more than one step, if possibly it can be avoided, and that no man need ever stoop over….

The principles of assembly are these: (1) Place the tools and the men in the sequence of the operation so that each component part shall travel the least possible distance while in the process of finishing. (2) Use work slides or some other form of carrier so that when a workman completes his operation, he drops the part always in the same place—which place must always be the most convenient place to his hand—and if possible have gravity carry the part to the next workman for his operation. (3) Use sliding assembling lines by which the parts to be assembled are delivered at convenient distances…..

The payment of high wages fortunately contributes to the low costs because the men become steadily more efficient on account of being relieved of outside worries. The payment of five dollars a day for an eight-hour day was one of the finest cost-cutting moves we ever made, and the six-dollar day wage is cheaper than the five. How far this will go, we do not know…..
