The HIDDEN Screws of PRECISION

I was surprised in the part about Whitworth, we failed to mention his use of rifling, another form of precision screw, to make the Whitworth cannon and Whitworth rifle, both of which used hexagonal ammunition, used in limited numbers, but famously effectively by the Confederates during the American Civil War. A Whitworth took out General John Sedgwick, the highest-ranking Union officer killed during the war at an incredible distance. A confederate with a Whitworth made the longest sniper shot of the time in Charleston, South Carolina during 1864. That shot remains one of the farthest sniper shots of all time. It remains the longest ever made with a muzzleloader. It was only bumped out of the top 20 sniper kills of all time by Ukrainian snipers during the current war with Russia.

I can't believe this. How remiss. Neither you nor Destin had the wit to include a URL to the jointly produced video. Now I have to go searching for it, and I don't know what to search for, because you didn't even bother giving the title of the video or some keywords that would alert us as to what the video was about. You know, you guys need to think about the people who listen to you and watch you, and think about what we need. Pinning a comment in the comment section giving this information is trivial. You could have done it in the description, but you didn't bother. By the way, it's approximately two years since Destin thanked you for the shout-out, so it makes me wonder how many more videos I have to search through.

Its not a micrometer, its a measuring screw

A micrometer or mycrometer (both are correct) is a measurement unit mycro =10^-6
So a mycrometer is 10^-6*meter

Stop saying screw. THREAD

I am sire education has not caught up with these people

Strangely entertaining

Just discovered this channel, and I know I'm going to be waiting for the next one every day after I watch through the whole of your channel!

I've always been fascinated by the most minimal things and most commonplace miracles we have, and still missed how fucking important screws are.

Fascinating Very informative upload.

What monster dips pretzels in beer ?! Mustard sure, but respect the brew!

Another absolutely awesome video! Thank you! 👍

It really is amazing how much tech has progressed. Things that were out of reach for a "hobbyist" type person a couple of decades ago are now things you can get for just a few dollars from Amazon. I think my micrometer cost me $10-$15 bucks. Obviously not a "state of the art" precise tool, but it's plenty for my needs.

ACME threading. My obsession with vises is my greatest vise. But who’s tolerances are tightest? Brown and Sharpe, Starrett, Mitutoyo, or… HarborFreight?!?
Hey, EXCELLENT production on this upload, with the very professional background tunes, and top notch timing and never too rushed or intense!

An old machine tool historian told me that Maudsley spent 30 years on improving pitch precision of his lathe lead screws.

I was disappointed to miss a mention of Donkins compensating screw cutting and dividing lathe - a great improvement on Maudsleys design and which ushered in true precision engineering in 1826.

Doing history is so easy! 😂

Dis isch keine gscheide Bretzel sondern eher eine Saltzschdage 😉

you can go back in history way back and there was the water screw it lifted the water out of a canal or river to another elevation yet it has nothing to do with measurement but rather volume movement of fluids it was operated by hand and that was its limitation it couldn't be made bigger or taller (long) so if for some reason you had had to move the water from to higher then the screw you just used 2 in tandem one filling a higher pound above from there you went with a second one higher - it still used till now and some called it ARCHIMEDITH screw but some scholars think he copied and improved on it

Great video !

I have a micrometer presented to my Grandfather from Browne & Sharpe (early 1900's) in a velvet lined eyeglass case-velvet lined. (Hudson Screw Machine Co. Chicago)

Very Good!

Ohhh man, screw me!

you sound like Esper the Bard?

Look into the Great eastern as My understanding is that was one of the largest watt steam engines made

@4.20, I reject your English of the written word "published" 😂

Thanks for yr work & research. Ive not brought a micromiter only used calipers - would have saved me a lot of time. Digital are good but when the digits start disapearing dail is best. Most people dont care for this sort of stuff - like bulls in China shops.

Have you looked at the base of your camera, that tripod thread? The standard is usually 1/4 W

Wow, pretty cool video, thanks!

Ughh! Why do so many people make the mistake of saying "also... as well"?

Yep this vid is screwed up.

White people are amazing 👏

If you liked the inclined plane, wait 'til you get a load of the screw.

Its absolutely incredible how you dont screw up to explain such a whole boring topic 🙃

We're all screwed. Our lives hang by the threads in the coils of measurement.

Without a good screw, none of you would be alive right now.

I've seen mechanical Swiss screw machines in action, in practical use, at a manufacturing company in Santa Clara, CA. It had cams and followers and arms, and it made screws faster than a modern CNC screw machine. It didn't look that fast, but the tooling was up close, whereas a CNC screw machine has a longer distance to travel before it can change tools. And there's the tool change time itself. I tried to find video of such a machine online, but couldn't find any. It's a marvel to watch, and you get a sense of the mechanical genius of it's inventor, though realizing that what I was watching was a derivative of the original.

This was an amazing video about precision screws and the history of all that it took to create our world today. Well not all but a lot! I'm very happy to see that you gave considerable credit to a few of the men who without them, we might be living in caves. lol

Two of the greatest inventions, one the IGBT transistor and the screw.

Disregard my comment on your other video I guess. But his work on the plane does warrant mention.

Where would we be without the standardisation of thread forms?

What would life be without a great screw. Very well done video Thanks

But how do we create more precise things?

Lol. Micrometer is probably made in the millions? Maybe per year?

This why i wonder how those fuckers-weekend-pyramid-builders did what they did.
