Barbed wire served as telephone line for early homesteaders
Usually barbed wire (aka the Devil’s Rope) is decried as what divided up the West and brought an end to the vast open prairies. In at least one case, we can see how it brought people together.
Early telephone companies found connecting rural homesteads too expensive so the farmers took matters into their own hands and used barbed wire to connect telephone services into their houses. This resulted in Party Line style connection where everyone could hear whoever was on the line. This was bad when you needed to have a private conversation, but useful to spread news, weather reports or the price of crops. Sometimes it just helped people be less lonely.
The details are in this fascinating article.

How carbide inserts are made
After watching this I now completely understand why inserts cost what they do.

Where does precision come from? I dig into the history and a bit of how-to for where the dimensions that are everywhere around us come from. I also introduce my first project – a recreation of the James Watt Micrometer which is possibly the first device used for measuring material at high precision.
Trans-Arabian Pipeline – 1947
It’s 1947. War is over, people want oil and Saudi Arabia is almost nothing but a giant empty desert. But there’s oil. Lots of it.
Sending ships around the gulf takes about 3,500 miles… but if you built a pipeline to the Mediterranian it would be about 1000 miles and could operate more or less continuously.
Enter the largest American civil engineering company – Bechtel. This video (courtesy of them, so take it for what it’s worth) documents their remarkable feat. From literally an empty desert they bootstrap and build all of the necessary machinery and goods to get the job done. The straight sections through the desert are fairly smooth sailing (though fascinating) but once you get closer to the Medetrain the terrain changes – not only physically but the political situations in various countries forces changes in plan, and even a CIA-sponsored coup in Syria. I’m sure it’s an oversight Betchtel forgets to mention that part.
If you were an oil consumer in America or northern Europe from 1950 through about 1976 you likely, at least sometimes, used oil that came through that line.
Amazingly, copies of their almost monthly magazine are online.
The Debit Card Cometh – BBC 1969
This remarkable 1969 BBC video documents the forthcoming horror of electronic debit cards – or specifically the problems we will face by putting many tellers and the personnel to reconcile accounts out of work. While surely impactful for those directly affected by the computers which put them out of work, I think most would agree on balance we are better for the higher efficiency of electronic banking. Witness smoking in offices and the suggestion of vandalism for non-acceptance of checks.
1930s Auto manufactoring
If you can get past the poor title, irrelevant thumbnail and soundtrack that will numb your ears after a while, a wonderful look into auto manufacturing in the 1930s. An impressive survey of the many skills and processes involved. You’d be hard pressed to find elsewhere such beautiful shots of asbestos dust or men putting their arms or entire bodies inbetween rapidly moving heavy machinery.
Turbo Encabulator
In my first project video I reference the famous Turbo Encabulator. Many are not familiar with one or how it works – this should help.
