At beginning, film shows a man feeding a bar of steel into a cutter. On the opposite side, a man handles the cut pieces. Next a man (unseen) uses a tong to move a hot piece of steel from a small furnace. He places it into a form where a machine then presses it to produce curved part. The operator (hands seen only) uses tongs to place the part into another machine that shapes it into a disk. The operator (now seen) uses tongs to put the disk into another machine that hot stamps it into finer shape. The man holds it for a closeup by the camera. Next, the same part is held by the man after further machining. It now has nine holes around its circumference. The part is then processed in a gear cutter and shown in closeup as a finished bevel gear.
At start, grinders are seen operating cooled by liquid sprayed at the tool faces. Closeups of grinding wheels in operation on creating a crank shaft. Scene shifts to worker operating a multiple milling machine. Closeup shows a cam shaft being milled with cooling oil flowing over the work surfaces.
Rim of Ford spoked wheel in jig as worker loads spokes into the wheel. Wheel turns as each spoke is pressed and welded into place. Worker holds complete spoke wheel after assembly. Wheels hung on overhead conveyor belt in Ford automobile plant.
Automobile panels being pressed by large stamping machines at Ford plant. WS fenders removed from presses by workers and placed on conveyor belt. Close up of panel pressing machine. Worker removes automobile roof panel from press and places it into a stack with other roof panels. Aerial view of assembly line floor. Aerial view workers plunging parts into fluid bath.
WS aerial view glass formed onto conveyor belt at Ford factory. CU glass emerging from foundry. Worker cutting glass into individual sheets. Workers pull glass panel from conveyor belt and another worker stands it on end for inspection. Glass is polished by means of a spinning fluid applicator.
Sheets of glass moved onto assembly line via indoor rail car. Workers washing sheets of glass with brush and then carrying sheets off to inspection area. Worker marking glass with wax pencil. Many automobile parts, including crank shafts, on overhead conveyor belt in engine assembly area. Assembled engines with transmissions attached pulled off overhead conveyor onto main conveyor. Engines with transmissions put onto individual dollies. Fenders and exhaust system parts loaded onto railroad car by workers. Engines with transmissions installed into automobile chassis. Workers push themselves on shop crawlers as they install suspension parts onto moving chassis. Body of automobile lowered onto chassis. Finished car driven off of assembly line.
