From the moment the massive boilers are lit to provide the steam to turn the generators so as to provide the enormous amounts of electricity required, the film gathers pace, A Motor City has become alive.

This is a combined series of special industrial films of the Chevrolet series. I posted a couple of these segments last year but this is the full copy. I think there may be one series missing, to do with the brakes but I hope it doesn't detract.

The information that came with this film is interesting so it's copied here:

Master Hands is a glimpse of the last year when management ran the plant according to its own rules. In the Central States, automobile production had recovered from its Depression slump by the mid-Thirties, and a long accumulation of grievances led auto workers to form a solid (and secret) organization.

Late in 1936, Chevrolet workers, first in Flint and later throughout Michigan and the United States, 'sat down' on the job, stopping production, sequestering key tools and dies, and occupying factories to enforce their demands for union recognition. This legendary strike forced the company to recognize and bargain with the United Auto Workers, which resulted in better wages, benefits and greater dignity for the workers of America's key industry.

This shift in power changed the automobile industry forever and stimulated labor solidarity and organizational activity throughout the U.S.

Finally, above and beyond the fascinating circumstances surrounding its making, Master Hands is simply an amazing film. Many sequences stay in the mind: casting engine blocks in sand; the engine inspector with a long ear tube listening to the sound of piston in cylinder; the winding of red-hot springs; auto frame assemblers standing inside their machines as they work; the gigantic room filled with vehicle frames in rhythmic motion as they are assembled; the 750-ton stamping presses; and the final moment of the movie, when the hands of a tweed-jacketed suburbanite take the wheel and the car, leaving behind its dirty and tired makers, magically drives away into a country wonderland.

This combined film has to be a classic of industrial archive history, from where these vids originally came from.
