I like how instead of using Google Images like anybody else, you go to the museum to get the footage that you need. Shows us how much time goes into these videos.
Yeah. Adds a little bit extra to the video... Probably a lot extra for Destin to get to see it in person so I don't think he minds putting that extra effort 😊
Took my toilet lid off yesterday doing some cleaning (I get thorough with the toilets) and mine were a material like nylon or something of the sort. My first guess would have been 5/16 ......28?? Not sure what normal tpi is for a 5/16 off the top of my head
I worked on my own cars in my younger days and owned a few Brit cars which I really wish were available today. The only problem was that I had to have three sets of tools, Whitworth, metric and Fractional.
Worked on cars for many years. Jaguar had whitworth back in the late 80's. Frustrating to have to buy a complete set of wrenches just to work on those Limey cars. I know that a lot of metric and inch come close and could be used but that wasn't our way. Had to be perfect so hundreds of dollars for Whitworth wrenches.
Me, a non-American: "A millionth of an inch, OK... that doesn't sound too small." Oh, well, I'll have to convert it... let's see, 1 in = 25.4 mm, so 10^-6 in = 25.4 nm... yikes! That's only about 1000 hydrogen *atoms* thick, and about 8 times smaller than the maximum resolution of an ordinary optical microscope!
To me a millionth is to cut it in to a million parts. But 1000 Millionth of a amp is1 amp so the numbers don't add up. as a millionth is 0.00001 that amount of shift to my is a greasy fingerprint. But saying that 0.025mm is 0.00098425197 I think if with take a piston out of a car and electroplate it how much bigger will it be and can we message it
@@alunroberts1439 What? 1000 millionths of an amp (1000/1000000, 1 microamp) is 1 thousandth (1/1000) of an amp aka 1 milliamp, not 1 amp. Did you confuse “millionths of an amp” with “milliamps”?
@@GRBtutorials I was hopping some one would pick up on it as in school I did hear 1 millionth 1 milli needing 1 million of them for 1 amp. but no 1000 milli amps is 1 amp so my thinking was take 1 amp chop it in to 1 million take 1000 of then to get one amp. I was at school at the time so should we say 1000th of a amp not milli amp. milli as millionth. I was hoping some one would see it. As I did one time ask if I take a steel rod that is 12 inches long i keep cutting it in half hoe meany times can I cut it in half I don't think I could do it 1/2 a million times so what is a millionth of 1 inch
The bigger problem, as stated in the video, is that it's hardly feasible to make measurements at that accuracy. Just having a geared reducer doesn't mean it is repeatable. Atmosphere and temperature changes, surface finish, microscopic contaminants and user variability mean that the repeatable accuracy may well have been 10 or 100 times worse than advertised. Even today it is highly uncommon (in machining or even grinding) to be making measurements smaller than several microns. It's not feasible in a production environment to control the many many variables involved to get results that are better than this, and, in reality, it is also rarely necessary.
As soon as the video started and he said that if it was missing it was because you lost it, I immediately knew it was your dad. All dad's are the same lol
The subject matter of your videos is always crazy awesome. I would drool so hard to peek through what I'm sure is a very large stack of your subject ideas over the years.
Micro, from the Greek micros meaning small; meter from the Greek metron, that by which something is measured. Metre is the measurement devised be the French.
very truthfully because they dont want smart factory workers,just stupid and obedient factory workers...the smart ones they do want,have to sign that abominable contract and God help thier first born....now you all just drink up your flouride..
Nah, by the number of screws in your body you're not broken, you're fixed up real good :-D And neither sniff nor drink superglue - tends to cure stiff - an inconvenience with moving parts. Maybe try some motor oil, for good lubrication ... also helps staying cool, that's why it's used when drilling and cutting metal L-D
Chris. To get a perfect helix onto a straight Rod for example, simply hold a piece of string on one end, and on the opposing side of the other end. The string will (when tightened ) form a helix. Trace that to the surface and make it a tool for shaping something moved along that rod and you get a helical shape, that would be my approach ...
Rotary broaching, it really is an interesting bit of machine tech if you wanna look into it a bit. Alternatively, rifling is also a common practice for the manufacturing of firearms specifically
In case anyone's actually interested, it was mounted to the side for elevation controls, so you wouldn't have to expend all the extra metal to hinge the scope rail to the muzzle of the rifle. You could then, swivel the shorter scope to use an arc and still be approximately on target over a much greater distance... What was discovered rather quickly was that windage-drift became the new issue and undoing of sharp-shooters over great distances. Primitive shooters have been using the "Kentucky Windage Technique" for considerably longer than even rifle scopes. It entails the effort to aim "for" something (someone?) rather than directly "at" it/them. ;o)
@@nullpoint3346 In pugilism (and related) the point of aiming "through" is to deliver penetrative power to the strike without over-extending yourself. A lot of injuries and falls are avoided this way, as well as being able to deliver more devastating impact and trauma... In shooting, you're trying to put the path of your projectile into the target... In very short range, this is easiest accomplished with a well aligned sight system (scope or otherwise) and aiming directly "at" said target... This has created terms like "point blank" (virtually no range at all) and "flat trajectory" delineating the "short range" for a specific weapon as the distance a standard projectile will travel without deviation... (an important number to know for any weapon). As you reach further out, requiring a scope to even see the target, however, the projectile no longer travels in a "dead straight" line. Bullets and slugs travel in "arcs", or portions of a circle, usually relating to how quickly gravity pulls the bullet to the ground versus how quickly that bullet also travels "horizontally"... "Windage" refers to the bullet's interactions with varied air flow during it's path. It's technically as much a function of right or left handed "twist" (the rifling in the barrel) as it is which direction the wind is travelling and how fast... "Kentucky Windage" was the old practice of shooting over great distances without a calculator, spotter's scope, or any technology to make up for these effects. SO in order to hit something a half-mile away (as opposed to within the flat trajectory range) you can't aim "iron sights" directly at the target. Surprisingly, humans have been judging wind and elevation for range as far back as we've had spears or bows and arrows... Even more surprisingly, the longest lethal rifle-shot in the world was during the American Civil War, when a Kentucky Long Rifle took a man off his horse from more than a mile away at The Devil's Tower (if I recall correctly), and it held that record all the way through the 1980's and possibly even more recently with Desert Shield or Desert Storm and a renewed use of snipers with full shooting systems. Both principles deal with being able to "visualize" in your targeting, as opposed to the literal "aim at" what you want to hit... SO it's not entirely dissimilar. All you really need to gain skill, is access to the maximum effective range to shoot your weapon safely (within reason) and a weapon that will give reliable and consistent results at any given range under repeatable circumstances... AND then practice steadily increasing your range to target over time under the given circumstances (like wind velocity 14 knots from right to left)... It takes a mountain of patience, but learning to "aim for" as opposed to "aim at" is plenty beneficial, especially for the out door ranges where a bit of friendly gambling can be had. ;o)
@@nullpoint3346 Always welcome, bro'! You don't get born with this stuff as instincts, so if I can shorten your research to finding out, it's worth it. ;o)
One thing not mentioned about Whitworth: back in the :70's, I worked as a weekend Triumph motorcycle and lived with the owner of Mac's Motorcycle Shop in Norfolk Va. We had a lot of special and specialty tools for British bikes including Metric, British Standard, and Whitworth! It was a blast lear ing the special tuning techniques, period changes (the newer the bike, the more metric they became), and history.
Once we got the data on the speed of the projectile I figured we should hear the impact about 1.8 seconds after the cannon was fired (1,800 feet to target / about 1,000 ft/s). When I went back and counted it was more like 3.5 seconds, which confused me for a couple seconds until I realized that the sound had to travel back 1,800 feet. Just so happens the sound and the projectile travel at close to the same speed (projectile at about Mach 0.9), so 3.5 seconds is approximately correct. Maybe a little obvious, but I thought it was neat.
@@markorezic3131 u r right. But then my joke wouldn't make sense because u wouldn't need any precise instrument to measure it, since we know it is zero.
I'm a laser calibration service technician so my day to day is usually spent improving the geometry and accuracy of CNCs and CMMs. Microns, millionths of an inch, and arc seconds are fascinating levels of accuracy! Very cool video to see how it all started! I primarily use a laser interferometer for my work. Keep up the great work!
could you care to explain to me how the distance between a hard disk and it's reader is measured, as I've heard it's the width of a human dna . (around few nanometers )
@@thirtythree160 I haven't really thought about it before. I'm not sure how much of an interest there would be. Some of the locations are strict about no photography as they are proprietary, aeronautical, defense contracts, etc. But, I do enough that is not controlled that I'm sure I could do a video if I wanted to.
@@downandout9753 Unfortunately I don't have a lot of experience with that specific type of measurement. From what little I know it works by comparing the harmonics ratio in a repeating data pattern then adjusted accordingly. My primary tool is a laser interferometer which compares the known wavelength of a fixed beam to one moving with the machine being measured. Both are reflected back into the laser head where the wavelengths are measured and compared. The way a hard drive head measures distance seems similar, but using different methods.
Son: "So why did the sharpshooters of the day prefer the Whitworth?" Dad: "Accurate...very accurate... Son: "Really?" That is such wholesome conversation.
Watch the Forgotten Weapons videos on them, as a muzzleloader they had about a 3.5moa accuracy, on par with a modern military rifle. An 1861 Springfield would be good to have about a 20moa accuracy, and most were more like 50. One MOA is a minute of angle, 1/60 of a degree. It's right about 1" at 100 yards. A Whitworth rifle could get 9 or more consecutive shots into a 4" circle at 100 yards.
Would you collaborate with TAOFLEDERMAUS to find out why GIANT backwards pellet shows mind-twisting physics? Center of mass is behind center of drag, and many commenters say that works for subsonic as well.
Fascinating! As one who works on very high precision CNC machines, I love stuff like this. Trying to explain to someone that your machine tolerance is < 20 microns is difficult. Great job.
Yes. I was stymied by the Whitworth system when I bought my first British motorcycle...certain fasteners required whitworth tools (because SAE and metric just weren’t fitting right...) Whitworth created a standardized method of measuring that is ironically, non-standard in modern day. (This is the BEST RU-vid channel ever!)
What year was that motorcycle? That's weird. They can't keep themselves from making things more complicated. I'd be happy if all bolts where they can were in metric.
Ran into that with electric fan motors on older BC ferries. they used Whitworth threads for the case & the support arms from the case of the motor to the fan housing shroud. I found some here in BC at a Jaguar dealer of all places.
...my wife had a Pontiac Phoenix, the Pontiac version of the nova. 2 bolts right next to each other, 1 would be 1/2 inch SAE and the one next to it a 12mm. Very frustrating to work on
@@soranuareane Great explanation! to put it in more commonly known terms that would be: 75 million threads per inch. One turn every 0.00000001 centimeters. About 7,470.6 turns every thou (thousandth of an inch). For reference, a sheet of printer paper is about 0.004 inches (0.01cm) thick. Pretty incredible! :)
I read somewhere but cannot find it online that several years before Watson and Crick deduced the double helix structure of DNA, a British mathematician figured out that the double helix would be a recurring structure in biological systems (and Watson and Crick were apparently unaware of his work).
Technically, it also depends on the DNA conformation at that time - there are three major DNA helix forms - A, B, and Z, plus several less common ones (C, D, ...). Each of those helix forms has a different TPI - most common B-form is 34 Å per turn, A-form is more compact at 28 Å per turn and Z-form is loose at approximately 230 Å per turn.
I remember seeing this video, when it was uploaded, almost 2 years ago and it blew my mind. I'm watching it again almost 2 years later and guess what, I'm still amazed by it. That's why this channel is amongst the best channels on youtube!
That's not uncommon. The actual units used are immaterial so long as they're consistently applied. The principles of precision are the same regardless of the unit standard used. When people outside of the United States refer to speed in Kph it confuses us Americans because our "reference unit" of mph is different. We don't think in metric. We think in imperial units. It's like different languages. We Americans simply speak a different language of measurement than the rest of the world but the principles are the same. Metrics are just as hard for us Americans to mentally visualize because it is a foreign measurement language to us! If you're lucky enough to find an everyday American who is at least familiar with metrics, they may know that a meter is roughly equivalent to a yard, or that an inch is approximated by 2.54cm but it all sounds like rubbish to us trying to imagine that 55mph is roughly equivalent to 62kph!
I love falling down the rabbit hole of "how did we arrive here?" when it comes to machining & manufacturing. I think part of it is while computers are great and give us things like 5-axis CNC mills, it's current and I understand them and the underlying concepts already. Whereas it used to be very mechanical and due to said computers, it's no longer current so we just don't think like that as much any more. So much truth to the saying "Everything old is new again." Thanks for the great video!
Destin, you SAY we're at the dawn of precision medicine. That probably doesn't mean much to most people. But genetically modifying a patients own immune cells to fight off the patients own cancer has been approved now (pretty sure I read that somewhere). Think about that, we analyze the cancer DNA, find out how it's different from healthy DNA, take immune cells and precisely modify them to be able to detect the cancer as a threat. Then we put them back into the body
Exactly, it's totally fantastic what scientists are doing. To give a little more detail, they essentially do the same thing that vaccines do. There are tiny proteins on the outside of every cell that let it interact with everything around it. Healthy cells have protein markers that let your immune system know that they're your cells and that they're not bad. Viruses and bacteria have markers that look completely different from healthy cells, and vaccines contain replicas of those markers without the bad parts that can hurt your body, so that your immune cells can detect and destroy the bacteria and viruses when they happen to get into your body. Cancer cells look a lot like healthy cells, but by analyzing the DNA closely as well as the cancer cell components, they can find the cell markers that are unique to the cancer cells, and then they can teach your immune system how to find those specific markers and destroy the cancer cells. I'm not sure what all has been approved or not (it might only be approved for certain kinds of cancer), but the technology is there and it has the potential to help lots of people!
My dad is my hero, and we just watched this together. There is something kind of cool about watching you hang out w/ your dad, while I'm hanging out with mine.

I never served, I just heard it from both my uncles, then my friends who enlisted, coworkers who had served, and from Reddit. I wouldn't know parade rest if it showed up in a tuxedo on my stoop.
Of COURSE your dad is a metrologist (and machinist?) I'm on the same path right now, machinist, metrologist, CAD/CAM designer, cnc programmer, everything relating to manufacturing processes. :D
Destin you made my day by introducing your dad and by mentioning what he does. Same as me, only I do more electrical metrology than mechanical metrology although I went to school for both. By the way the slightly longer USAF definition of metrology is the science of weights and measures. I always thought since weights was part of the definition there should be something electrical in the definition. However as you show in your video it all began as mechanical as far back as the Egyptian Royal Cubit used to build the famous Pyramids. Your video was much more enjoyable than just showing a standard Supermic with encoder and digital display or a laser micrometer. I always wondered where you got all your curiosity and love for inventing and all things technical. Now I know. I am curious if your dad went to school like I did for metrology or did he learn it OJT as a machinist? I saw the brown machinist tool box behind your dad. Thanks again for making your channel as a newer viewer I am still catching up on the older videos but especially liked your recent nuclear submarine videos as well as the musical oscilloscope! Keep up the cool work dude. :-)
10:26 The PC I am using to send this message is held together with screws! The motherboard is attached to the case with screws, and the case is actually held together with 10 large screws! Thank you, Sir Whitworth!
It genuinely brings a tear to my ear when you think about how important this kind of stuff is, how critical it has been for our progress and how little the everyday person is aware of it. Thank you for endeavouring to bring light to these topics and making them available to everyday people. You are doing a great service.
What a great video! Sir Joseph Whiworth was born about 8 miles from where I live, pretty much the birthplace of the industrial revolution. His legacy helped build the Christie Hospital, one of the largest cancer treatment centres in Europe!
Back in high school Physics class we were measuring modulus of elasticity of a steel wire by adding weight to it and measuring its elongation with a simple mechanism. The wire was attached to a rotating cylinder that had a small mirror attached to it. By sighting thru a sight with crosshairs at the mirror and viewing its reflection of a linear scale some distance away, we could very precisely determine the cylinders rotation angle and thus, the wires elongation. I did the math and figured we were measuring to something like .000001" accuracy.
Two guys were walking home from the bar at night and stopped on a bridge to take a pee. One man said to the other, "Man, this water sure is cold." The second man replied, "Deep, too."
Fantastic. Great to see the Whitworth Cannon in Action. Its Accuracy was so good it was used to counter the opposing sides Artillery. The Rille and Riffled Cannons only drawback.. Expense.

Love when your videos pop up! Always a treat and something I'll talk about all day. Was doing some reverse engineering this morning in CAD and the closest thing to me is my digital caliper. It has a pair of 4mm M1.4 x 0.3mm thread screws in the battery door. On a side note, LOVED the Whitworth cannon slow-mo shots! That was simply amazing man! Bravo!

Leaning against my desk is a 12 gauge Iver Johnson shotgun (1939-1941, I believe). The internal bolt that secures the stock to the lock frame is a 7/32 inch major diameter by 24 threads per inch BSW Whitworth.
The closest fasteners to me are two 1/4”-20 brass bolts holding down this toilet 🚽 I’m currently sitting on while watching your video. Does that count? I’m telling you, I have a whole new appreciation for this Whitworth fellow!!!
Worked as a machinist over 30 years and today was the first time I'd heard of a metrologist. Seems google hasn't heard of it either. Red lined it, had to add to dictionary. A real smarter every day. I think this is my favorite. Good job, O'dan
@/X/EN but the diameter of the thread, does it match a imperial thread with 12 TPI? and unless you have a thread gauge its really hard to get a precise TPI count.
I'm currently sitting at my desk at a cold heading company that produces threaded fasteners watching this on my lunch break and feel like this is very specifically targetted at me.
As someone in manufacturing, it's amazing to hear how one man helped make the entire industry what it is. I use a surface plate nearly every single day to perform measurements and I had no idea that he made it possible!
Man, you should look up James Watt too. The wikipedia article doesn't do justice to a man with his name on all aspects of mechanical engineering. Also, Chebyshev. Cool Russian guy , also with his name on everything.
Until fairly recently, tripod threads were commonly 1/4-20 BSW! Today they are standardized to 1/4-20 UNC which, like the BSW has a deeper thread than the typical 1/4-20 hardware you might find at the hardware store.
Are you concerned that there are privately owned cannons in the world, or that they're live firing civil war era cannons? Because they're just replicas, not originals.
@@Laptop46 Ight den. It's not as uncommon as you'd think, actually. Most cannon shoots aren't actually civil war era driven, it just happens to be that the era in question made a lot of good cannons to reproduce. Some guys just use chopped up welding tanks to shoot bowling balls because they're cheap and easy to make, whatever floats your goat
