Ford Model T
Work began at one end of the assembly line, starting with an empty chassis. From there, the chassis moved slowly down the assembly line. Workers on the assembly line added parts to the chassis. Before long, a new Model T rolled off the other end of the line. Different body styles were available, even a truck, or Model TT. At first, the only color available was black. Black paint was used because it was cheaper and lasted longer than other paints and Ford was obsessed with increasing profit. As car paint got better over the years, Ford began offering other colors. The time it took a chassis to become a finished car was over 12 hours when the first Model Ts were built. By the time the last Model T came off of the line, Ford had so many plants, it was making one car every twenty-seven seconds!
