I've just inherited one of these from a retiring engineer. I gave him a puzzled look and told him I have no idea how to use this because I've only ever used digital.
He gave me an earful about "back in my day" , "you kids" etc.
Luckily for me, I have the internet now unlike him when he was younger. So, here I am watching your youtube video guide lol
49 plus years I have been using the manual Vernier. I still prefer the manual one. Great piece, great tool.
My 1.20 metre Vernier is a jewel for me.
Very good video ! Cheers !
In college, early 1970s, I took a drafting course and learned to read verniers using drafting machines. I still use vernier measuring tools today including .0001" micrometers, . One is an 18" vernier caliper. It's a beast but it's accurate.
I didn’t gauge how useful this would be.
Stay safe with your family 🤘🏻
As a machinist I use them daily. And I like the analog better then the digital.
But it’s still a guessometer 😉 for the work I have to do sometimes. Great video and a great explanation.
Noob!! We are now in the 21st century in where our current technology makes much of our lives easier and yet you still choose to make your life harder as if your left behind 100 years!!
This was great! My job used to require that I use calipers, but they were all digital, so I never learned to read a Vernier scale. Can't wait to check out more of your videos!
Never used these at school in the 70s but was just given one & realised I had no idea how to use it, this video has helped me enormously…..although I do struggle a bit as I have dyscalculia which causes me problems.
Brilliant...just prdered a Mitutoyo MIT530-104 and am dying to start measuring stuff...I didn't know how to use it so thank you very much...perfectly explained!!!
i bought a really old once from a second hand shop, then cleaned it and its measures are spot on! go it for only 10€ and its super well bult. best tool invesment in my life so far.
Excellent video and explanation. How such a simple device can be so accurate is amazing.
I am 52 and I still have the caliper from a job when I was 22. It’s the only one I have, but being American I usually use the top scale. That is until I got into FPV! Now I use the bottom scale more often. Works perfectly. The beauty is that it cannot be wrong, where electronics can fail and become inaccurate.
I work in HVAC engineering. We use a lot of quality mercury bulb thermometers. We calibrate our instruments with these thermometers. Our electronic thermometers get out of calibration. Mercury bulbs never do unless you break it. Relative humidity is verified with a wet sock on a mercury thermometer and a fan blowing across it. Dry and wet bulb temperatures are converted to a relative humidity on a psychometric chart. This stuff is not obsolete. It’s the gold standard.
Great video. Never need a battery! Cannot be wrong. (Unless it was built wrong then you get what you pay for, but it’s still going to be repeatable).
Watched this at work! I learnt how to use it at college but I forgot. Needed to use one to measure something as we don't have any digital ones a certain size on site atm. This video helped me so much. Thank youuuuu
Brought back nice old memories..thanks
I've found them to be an amazingly useful tool for all kinds of building tasks.😎
Simple yet genius! Thanks!
That was a trip down memory lane. We used to call them the " Guessing Stick" Like many engineers of old I still have my old kit and sometimes use it.
I have manual and automatic calipers and micrometers. I'll be honest I haven't used the manual ones in years I got lazy and spoiled as a boss from years ago bought me a good quality automatic caliper and micrometer. Good info as always. Stay safe Lee
Really, really interesting! Thanks, Lee! 😃
I had an electronic caliper that the battery leaked inside... 🙄
So I bought a second one, but I keep the battery out of it.
Anyway, stay safe there with your family! 🖖😊
Thanks for making that skill so easy👍
Well done refreshed my memory
thanks broski literally learning engineering as a millwright trainee right now and this was super helpful seeing as i was a little lost on the measurements yesterday
Brilliant simple explanation! Thanks for posting I’m measuring up for some excavator pins and bushes and I have the same one👍
Thank you. First explanation I understood clearly. Very easy. You might even say painless.
I learnt using the vernier calipers at vocation school 20 years ago and i used it all the time. But my eyes had other plans and now im forced to use a digital one with huge numbers. And since thats the only thing ive used the last 10 or so years, i had almost forgot how to use the manual one. But it came back quickly after watching this video :)
I never learned how to use a micrometer however... Guess thats the next video im off to see ^^
I still have Vernier Calipers like those along with a Micrometer. Nowadays, I do find more modern examples quicker and easier to read though.
As a rule of thumb, I measure things.. :) Thank you for that video!I Have been wondering about getting a set of Calipers and although digital might be the way to go, I think the reading of the 'old school' calipers teaches us not only the numerical measurement value, but a visual way of reading measurment through a step by step value.
I'm looking at getting a Vernier Caliper and the digital ones are either crazy expensive or seem to be made of garbage. This led me to look at the analog ones only to find I had no idea how to read these things. After a quick Google search and your video being the first result, I now understand how these work and will be going analog over digital, thanks to your fantastic explanation. Thank you for such a simple but informative video
Good vid. I'm a toolmaker by trade (Camborne School of Mines Cornwall). So was taught both metric and imperial in fractions and decimal. I have all my Grandads measuring gear passed down to me, he was a shop foreman in the Midlands.
I was taught all of this back in the 80's and it is still something that I use regularly everyday. There is a sense of connection measuring things the same way that your grandfather probably did.. Happy flying!
Takes me back to my time in the BSA Motorcycles apprentice training school in 1971! All inches then though.
Cool, thanks for the knowledge.
Just be given one of these! Thanks
thanks dude got an exam next week .this saved my life
Thank you very much Sir for this video.
❤️
I started using it 45 years ago....and i still use it :-)
I've wondered how they work so thanks! Only thing I'd add is that the process of taking accurate measurements with a caliper is a bit of a skill by itself. Materials tend to all be plastic (to varying degrees) and you need to use the right amount of pressure for extremely accurate readings.
Micrometers are better for extreme accuracy
I don't use calipers very often, but when I need to, I need to. I had an an electronic caliper that was accurate and easy to use, but because I used it so seldom, when I needed to use it, the battery would be dead. Grrreat. I bought an analog caliper and I love it. Plenty accurate for what I need and it never fails to work. This video does a nice job of explaining how to use one. What's next? A slide rule?
For years I kept a slide rule, it belonged to an engineer who worked on the space shuttles. Sadly it was among the items lost in a move. Hadn't thought much of it till you went old school. I actually used it in high school, by the time college rolled around I had to buy a Texas Insterments calculator, weighed like a brick due to the ni cad battery pack needed for the drivers and led display. Ah memories ....Take care.
I still love using these non electronic versions of tools. Always ready to work and takes that little skill that I was taught many years ago in those engineering workshops to read. A connection with those generations before who used the same stuff..
Thank you for sharing
The moving bit is called the Vernier or Moveable scale and the error when looking at the lines sideways is called parallax error.
Thank you so very much, take care!!
Thank you, sir!
But Lee, I need thousands! You guys are using sillimeters and it’s confusicating for us advanced enginerds in the States! First time ever that I have seen MM Calipers, thanks for the adventure. Silly Old Man over the pond.
:) One in the series "You know you're old when ..."
I have two of those, and I bought a digital one just for being able to easily show the measurement on blogs posts and RUclips. But the "old school" ones are the acurate ones that I use to measure. The cheap digital one is purely to show the number. :)
I am still using one👍
as a machinist that was the first tool i was taught to read
Love it !
How about a Slide Rule - still have my grand-dads ivory one.
I wish I had one of these. I prefer the analog version, but they are actually hard to find for a reasonable price for my usecase. Everytime I use my digital one I wish I had one of these
Hi there I've had one before and wondered what the other markings are for thanks
I love my callipers. They’re one of the few things I own with a lifetime warranty.
Appreciated mate
There's scope for a follow-up here, e.g. explaining the four measurement options: internal, external, depth and shoulder; checking diameters several positions around the part; and care of this precision instrument.
Interesting idea, thanks for posting.
Good video
This is a good tool to have. And this is the right way to do it. Never trust digital. No matter how many times its calibrated.
I kinda feel the same. I've seen digital give odd readings when they were not calibrated or the battery is low.. :D
It's hard to believe we need a video for this. I use a vernier and dial indicator everyday. Should be taught and used regularly in grade school.
Sadly, it is a dying art. Cheap, accurate battery operated calipers are easy to get. As an ol' school engineer - I prefer something that will always work, can be used in all conditions (even wet) and will work even if I forget to bring fresh batteries.. :)
We call it the Nonie scale in Europe, and i have been using it since 1983.
Thanks
The light dawns. Thank you.
One big reason I stick to digital calipers is my eyesight, I find it much easier & quicker to read a number than have to look closely at notches or a dial to see what measurement points are closest together.
When using a vernier calliper an understanding of the Abbe’s principle is recommended.
I carried a slide rule in my book bag, as backup in case my hp calculator ran out of charge before the end of day. Memories 😆
Still have a couple that I use, Just need magnifying glass these days to see which is "In Line"..
Cheers for the instruction, I've decided to go back "old school" after experiencing bad quality digital verniers.
in germany, the optical shift effect is called paralaxe. it means, the meassurement will become wrong, if your point of view isn't exactly over the corresponding scale section. and as humans have 2 eyes, it means you'd have to close one eye for meassurement to avoid a paralaxe-failure.
bonus information: i wasnt allowed to continue using this tool after dropping it accidentally to the ground. hat to throw it away and use a brand new one. thats how sensitive this tool is or how high german's quality control actually is.
It's a parallax error in English too.
I've used manual dial calipers for years. Never bothered with the digital nonsense.
Do you think you could do the same explanation for Imperial? I get it is probably the same gist, but it seems a bit harder to understand for me with all the fractions and stuff.
I was never taught that. Imperial was out of favour here in the UK starting in the 1965 and I'm not that old... Happy flying!
I got a set of those that are from USSR, 100 Micron (0.1mm) resolution, and use them occasionally when I can't find my $5 eBay knockoffs or the right battery since it chews through those coin cells!
The cheap digital models never completely turn off, hence the battery drain.
@@loc4725 neither do the legit ones like my Mitutoyo pair. Its just that the SoC is better and software has deeper sleep features. Also it has protections against giving crap readings when the cell is going flat.
nice
Super..
Used an old vernier height gage at work, read same way . Need good eyes
Yep, I'm at that age where the glasses need to be popped on to read the darn thing! :D
Not "memory lane" for me. I still have two of them and use them regularly. Though mine is just to the 10th of an mm.
But I'm an old civil engineer, and during my studies and the first years of my career, we used a sliding mechanical calculator, I don't know the exact English word. But a funny thing from these days was if you asked an old engineer what two times three was. He (cause it was only men these days) slid his calculator and said: "Well, it's aproximatly six"
I still have and still use 😉
I like these better than the digital ones because I like to use my brain.
i learned on those, now im too lazy to not use an LCD one lol
I think wiping the jaws is the first thing everyone does when picking up a caliper :-)
Always got to remove the filings from the last time you used them!
have been using these since 1992 in metric but still don't know how the top imperial part works.
Exam in 2 hours and i finally understand it
Best of luck!
@@Painless360 thanks
And cordless too :-)
A good pair of mechanical calipers is not easy to get now. I prefer them over digital ones because the measurement can be trusted.
And no batteries to go flat! Happy flying!
I love you
Trained on manual , digital is far easier especially when going between metric and bananas 😅
Hang about, what are the measurements on the top bit then?
Imperial - Inches, in decimal.
Still use mine after 60 years ,My big problem is I still have NOT! got my brain to use metric!! I still uae thous!!
I only learnt this last year, aged 40
I only learnt this today and I'm 69!
Next lesson, "How to use a slide rule", "How to use a french curve", and "How to use a protractor and compass".
Not a bad idea, I'm sure that some would find it a trip down memory lane!
Keep the caliper free of rust and it will most likely continue to function for millennia, certainly much longer than the battery/circuitry of a "modern" digital caliper.
It seams mad to me that people wouldn't know how to read it... Like finding out some doesn't know how to read an analog clock.
We all had to learn but things like this are a dying art as you only see the ones with digital readouts in many shops now..
@@Painless360 after retro fitting a dro to a mill it is easy to see their appeal. They are much easier to use.
Nobody was born knowing how to read a Vernier caliper. NOBODY knows until they are taught.
Not good to learn how to use, now I understand my order for a spring clip to hold plates on my dumbbells curve bar is not going to work. 🙃 My bar is 23.5 mm and the clip I ordered is 28 mm. Too big will slide off bar.
In millimeters is easy! But in inch?!
I'm guessing you are in America? :) Out of interest, how does that work?
No, I'm in Europe, and my interest is the knowledge. After your video clip, I looked for how to measure in inch, not with 1/200, 1/500 or 1/1000 precision, but with 1/64, 1/128 (for example, how do you get a result of 2 73/128"?). Without paper and pen seems to be very difficult to get the real value from the vernier! Metric system is marvelous!
This is also how to read a sextant.
If the USA would drag its arse out of the stone age, we'd only need to read in metric !😎
We still use mph in the UK for speeds.. 🇬🇧😁
