Title reads: "Power" Photographed and Produced by Morris Motors Cine Dept at Cowley.
A fairly technical discussion of how engine parts for Morris cars are made.
VS of water rushing over rocks in stream. Voiceover talks about harnessing power to mans' industry. VS of windmill turning. VS of water mill in action. VS of hydroelectric power stations and dams.
MS of an engine - cut away shots show the different parts of the engine working.
VS of molten metal being poured in a mould. Mechanical hammers are used to shape red hot metal into parts for the engine. VS of ingots of metal pressed between rollers. A crankshaft is cleaned of excess metal. More shots as the crank is finished. VS of gear parts are ground on a lathe. Teeth of the gears are cut in different ways. They are then hardened and ground down. Various shots of connecting rods being made. They are started as rough forged items and then finished by various cutting processes. Lots of drilling and cleaning with duplicate jigs. It is then bored to size for the crankshaft bearing.
VS of metal being cast in a mould. Engine cylinder blocks are cast and drilled. Bearings are bored and reamed. VS of cylinders being bored and rolled. VS of dies for casting of piston heads. The pistons are then cleaned and bored. Multiple drills are used to make holes. A shaving lathe then cuts the piston to shape using a diamond cutting edge. Various parts are rough turned from steel rods using automatic lathes. The parts are then cleaned and polished. VS of screws being made.
VS of Morris motors machine shops where engines are being assembled for cars, vans etc. Shots of an engine being assembled by technicians. VS of engine being tested on a test bed.
VS of Morris car being driven through the countryside.
BRITISH PATHÉ'S STORY
Before television, people came to movie theatres to watch the news. British Pathé was at the forefront of cinematic journalism, blending information with entertainment to popular effect. Over the course of a century, it documented everything from major armed conflicts and seismic political crises to the curious hobbies and eccentric lives of ordinary people. If it happened, British Pathé filmed it.
Now considered to be the finest newsreel archive in the world, British Pathé is a treasure trove of 85,000 films unrivalled in their historical and cultural significance.
British Pathé also represents the Reuters historical collection, which includes more than 136,000 items from the news agencies Gaumont Graphic (1910-1932), Empire News Bulletin (1926-1930), British Paramount (1931-1957), and Gaumont British (1934-1959), as well as Visnews content from 1957 to the end of 1984. All footage can be viewed on the British Pathé website. www.britishpathe.com/

Oh, something to remember: We see a lot of automated machines in this video, that once started, do their own thing. *There were no computers in the 1930s.* All of this was done via analog timing systems. Think of all the gears and such you see in an old clock, only on a much larger scale.

If this were a modern program there would be an announcer telling you what you were going to see, telling you what you were seeing and then telling you what you'd seen. Then they'd tell you what was coming up after the break and then they'd show the same thing. They'd easily stretch the 17 mins of this video out over six one hour episodes and throw in some TV jeopardy to sex it it up. "Can Bob change the tool in his lathe in time to get the pistons ready for the deadline? Stay tuned to find out after this word from our sponsors".

If it was Australian TV, it'd be half an hour long, with the manufacturing processes acting as filler material (20% of the film) while we explore the hardships of poor ol' John as the Elizabeth manufacturing plant finally closed, his workplace for the past 30 years. We'd hear about how it's affected his family and how he worries for his kids. It'd bang on about the community and there'd be plenty of shots of John looking on into the sunset, across his pool; somberly watering the garden in front of his huge house, with new boat in the driveway.

@@visionist7 I think that's a bit of hyperbole to be honest. An engine from that era would be expected to last at least 20,000 miles before a rebuild and survive several rebuilds. Given the low speeds and crappy roads of the day the engine, with a rebuild or two, would likely out-last the rest of the car and even getting to first rebuild time would be a minor achievement.

I don't think they open die forge crankshafts anymore, but in the wider scheme of things not a lot has really changed in the production of forged and stamped components. Machining of parts is where a lot has changed.
