Very cool, and sad at the same time. Back when we had heavy industrial infrastructure and a "can do anything" attitude. Sad because it feels like we took steps backwards.

I thought you were 'Murican?

And another heavy turning video:

Just look at that insert size!

Action shot at 1:14 doesn't look like much but it's with 1.5" or 38mm DOC and 1.8mm feed per rev!

British film is it? Still applies over here, replace that barrel with any number of our battleship guns.

British film is it?

Just a guess
Making Armstrong Gun (1920-1929)
"British Pathé"
Making Armstrong Whitworth factory. Newcastle and London.

Industry; weapons. Step-by-step film of the making of a large Armstrong gun at the Sir W. G. Armstrong Whitworth and Company. factory in England. Some very good industrial footage; c. 1910's or1920's. Workers take pieces of pig iron from a huge pile and load them onto a container which is lifted by a chain. Workers tossing pig iron and speigeleisen into Siemans Furnace; to make steel.

That was a neat show. Thanks. JR

Those old films are very addictive - industrial porn Interesting to see so many parts, made of wood, carefully fitted together, to make planes, much like wooden ships. So much human labor involved, and, sadly, because of wars.

I got hooked and watched for over an hour - once the power (and internet) was restored. Some powerful winds have been tearing through the area. I heard a loud thump and looked out to see what looked like a tree fallen on the back of my other house. But closer look I saw that another large branch had broken off the big sycamore. A bit later I heard the tell-tale bong - 2 seconds dark - lights flash - bong - then out for good until BGE came out and had it fixed an hour later. That was a recloser or sectionalizer acting on an overload.

" ....So much human labor involved, and, sadly, because of wars...."

Yep! Like it or not, there's just something about war that provides a lot of motivation to man!
Wonder what we'd be like now if we'd lived in harmony all this time?

I wonder if there was a relationship between that British Armstrong name and the U.S. toolmaker by the same name? I had a boss in the AF named Armstrong, whose great grandfather (or maybe it was a great uncle) who had started the Armstrong tool business. ...a really nice, fun guy to be around.

He's holding his gage incorrectly: warm hand skews the reading.

And the swarf was shipped out - cut to size - tempered, and then used as coil springs to support cars lol

I had to look that one up.

Spiegeleisen is a ferromanganese alloy containing approximately 15% manganese and small quantities of carbon and silicon. Spiegeleisen is sometimes also referred to as specular pig iron, Spiegel iron, just Spiegel, or Bisalloy.

[BCRider]

Yep, two things drive such efforts.... War and money. There was no lack of similarly grand work done on the large steam engines of that time that ran the ocean liners and freighters used to separate money from the public. Or the stationary plant engines that ran the plants that made other goods. Things were large and grand back then in the foundries of that time.

Certainly a good peek at what it was like and what a plant built up to allow for handling such items.

Still a hobby lathe

"A removal rate of 20,000lbs per hour in alloy steel of 30 Rockwell hardness in a cut that removes 6" off the diameter"

One of my favorites from that time is 1930, Ralph Steiner, Mechanical Principles. It's 10 minutes of weird gears, levers, cams and other simple machines doing their thing to soft music.
