Step measurment and China Export was new for me. Thank you very much.

That's an urban myth. CE is self certified anyway, and the wrong spacing is just a result of Chinese exporters not even giving a crap about putting the logo on correctly.
When I started in engineering I “could” read the vernier callipers tenth by naked eye, when I retired I “could not” read a digital vernier without glasses. 😂😂😂😂😂
When I started work, I was taught to interpolate the 1/64" graduations on a rule to thirds of 1/64", which is pretty near measuring to 0.005". I was pretty sceptical at first, then after a while, found it really worked. (with relatively young eyes) I expect others reading will be sceptical, too... In engineering, there are a lot of oddball personalities. Advice to the youth. Watch the older guys, maybe especially the quirky ones, see who produces most with least sweat... They've got the trade sorted. They're the ones with useful tricks to teach... If they like you... They're the ones who have all the oddball bits of kit whose purpose isn't immediately obvious... Until you see it in use... Often they gauge, rather than measure, for speed. With some oddball piece of kit...
Not only. Some calipers are simply hard to read. Grey writing on slightly different grey steel. Workbenches may be well illuminated - but calipers are often used elsewhere where lighting is not optimal. The digital ones have a clear advantage there. If they have a display with a reasonable contrast. Many have dirt cheap displays with low contrast. And if you have to use a digital one at below freezing temperatures - good luck. Some LCD displays simply become super slow or entirely unusable at low temperatures. If the measurement electronics are still working accurately enough, that is. And mine drains button cells quickly even when not in use. So there are good reasons to keep a vernier one around.
@@ralfbaechle Notice however, that calipers are "measure and take" instruments. Simply close them on the measured part, take them off, and read in better lighted place.
I few months ago I asked a guy at a bearing supplier why they had Vernier calipers on the counters; the answer was "The Boss wouldn't pay for the batteries, dial-calipers were a bit fragile, and anyway, they kept disappearing out the door! The sort of 'Scrote' who nicks digital calipers doesn't know how to read a Vernier, so he leaves these ones alone!" She's a great world we live in!
@@sunriseboy4837 : You can't beat quality! I admit I have three cheap Chinese calipers, scattered around the house and workshop, and never had a failure. I buy batteries from a cheap, reliable On-Line supplier, and keep a spare in the case. They are absolutely fine for times when absolute precision is not needed... if I am machining something for a sliding or press fit, I am quite happy to use them until I get close, and then swap to a micrometer. Ageing eyes makes the readout welcome, while the micrometer's Vernier requires serious squinting! BTW: I have a good quality digital caliper, bought when they first appeared. It cost about twenty times as much as the Chinese "throwaways", is not a great deal more accurate, and has much smaller numbers. What I hate about it is that if it times out, it does not retain its settings... you have to zero it each time, which can be a disaster! I doubt if I will ever use it again!
Another trick I use when using a digital caliper when facing many parts to length in a lathe or mill (or any measurement for that matter) is to set the caliper to the desired length and ZERO the readout there. When you measure any parts, it will take the guesswork out of how much needs to be removed to get the parts to final size.
or to determine the hole spacing of two identical holes: measure the hole, set to 0, measure the hole outside/outside with the inside measuring jaw and you have hole center/center
Good old fashioned engineering will never be bettered by a computer as engineering creates the computer. Why do we teach young children (not kids) to rely on a battery tool - the Victorians had no batteries, Vernier Callipers, Slide Rules if the computer is broken the older generation will use old fashioned tools like a multimeter to effect a repair. Above all your times tables are sacrosanct if you can - play darts and use mental arithmetic for the answer if you know maths the rest is easier, no maths then you are up a creek without a paddle. Never, never throw the baby out with the bathwater. This earns do not forget where you have come from.
Yes. Now I've got to go look my tools over to see if I've got any China Exports. It never ceases to amaze me how those with less quality try to pass themselves off with deceptive markings.
I'm 75 and have used vernier calipers and digital calipers for many decades, yet you were able to teach me a few things. Good job! Thanks for taking the time and effort to post this excellent video.
Yeah, I've been using all types of calipers every day in my occupation for over 20 years and I still learned several things in this video that I never knew!
I'm 82, and overnight I (in my dreams) decided to do bore measurements to determine the correct size of a bore for a minnie ball. Yep, you guessed it. Received a Euroarms M1853 Enfield. Hot dog. Fortunately I have in this room a mechanical dial caliper and three Verniers (1 being micro). I also have four slide rules and...a magnifying glass.
I'm a retired machinist, instructor and process engineer. I found your information to be very sound. the only thing I will add is to be very, very careful when relying on the depth rod as it's easy for inaccuracy to creep in. The other thing I'll note is that my Verniers are more difficult to use than they were 50 years ago when I was 20 (all you older guys are chuckling over that, I'm sure). On the plus side. I dropped my verniers in the bottom of a screw machine- a very dirty environment. They made a soft landing in the carpet of chips. I fished them out, dunked them in mineral spirits, wiped them off and they were none the worse. My boss did the same thing with his dials. They were toast.
Inaccuracies creep in with age and wear... it's just that in our case the age and wear is not necessarily the caliper! I 100 percent get where you are coming from! 😜
Also, with the dial calipers, you can get dirt etc in the rack and it will put them out of zero without you realising. The dial needle won't read zero when the caliper is closed. I prefer a vernier caliper with fine adjustment.
@@thomasdecker7631 we chuckle because we can relate! I had a magnifying glass in my toolbox. When I was in an area of the shop with poor lighting, you need the extra help!
@@Funco1979 That's why long ago I got in the habit (a habit I always shared with students) of checking zero before taking measurements and again when I was done to make sure that hadn't happened during use.
65 year old engineer here. Lots of great information in this short video. I use a vernier caliper simply because it needs no battery! I was also taught to never touch the measuring surface without wiping it clean. Sweat is corrosive and can cause corrosion pitting although these days they are so cheap maybe this is not so important anymore. Thank you!
64 year old quality engineer here, today they are made of stainless steel, so don't worry about sweat, but it's good practice to keep them always clean so you can rely on your measurements 😊
I got a digital calliper a while ago. You know, step into the modern age and all that. But the battery dies on your when you need it the most, and the digital measurement is very flaky. I got fed up with it pretty quickly and got a good quality vernier calliper instead. Bombproof, accurate, and never runs out of batteries.
@@CristiNeagu you get what you pay for 😄 Buy Mitut.... and the battery will last years and is so accurate, tested with gauge blocks mostly 0 deviation or +- 1/100 mm..... you'll never need a replacement....
@@anthonywalsh6605 we mostly have Mitu.. in the factory, some Mauser...., so reliable in harsh conditions, I got lazy and replaced my 150mm at home with Mitu.. Digital, only the long guys are traditional as I use them rarely..
That's a superb explanation, I didn't know about step measurement. In our Polish workshop we have old “Made in USSR" calipers that we use daily, after all the years of use, they have surprisingly little amount of play. But for anything that requires proper precision, we use digital one. Also, a small bit of trivia: In Polish it's called "Suwmiarka", which roughly translates as "Glide scale".
As you mentioned about 'Play' good Mitutoyo Vernier caliper, made in Japan, have a thin plate on the sliding member which can be adjusted with two fine screws to compensate for any wear and tear. Also an additional sliding member is attached to the main reading piece with a Thimble and screw. This is for fine adjustment while measuring. Thanks.
I started using caliper on my RC car when setting up the steering, suspension and camber of the wheels. Ever since doing so the handling is out of this world. The RC car I race is in 1/12 scale and I can use real world set ups by scaling down. I also used them to construct a aniti roll bar for the suspension on the front and back of the chassis and this has given me a car that handles like a dream. Because it is front wheel drive i now get that lift off over steer just like the real thing.
Note that resolution and precision is not the same thing. The digital caliper has a resolution of 0.01mm, but not necessarily that level of precision (check the datasheet). Also, a lot of measurements are tricky to perform by the operator. There's a thing called MSA (measurement system analysis), which is used to determine how reliably an operator can make a certain measurement
True, but often times resolution is more important. My primary use for calipers is that I zero them to some reference and then use it as a comparator relative to that reference. This renders the precision far less important than the resolution and repeatability.
38+ years machinist here, one thing I would add, when using the blade type calipers, use only the blades when possible. I have measured a plug gage with the blades, then on the heavier flats and gotten a .001" difference. I unserstand that sometimes it can't be helped. Also, search pictures of the Starrett vernier calipers, the only have the main jaws, and they aren't bblades, but nibs that are flat and parallel on the inside (for OD measurement), and radiused on the outside (for ID). There are seperate scales for ID and OD so you don't have to compensate. You didn't mention mechanical dial calipers, no battery and easy to read. Last year I had to replace my 20 year old Browne & Sharp 6" dial calipers when they decided to kiss the floor. I would have sent them for repair, but my company bought me brand new ones. Now owned by a Swiss company, Tesa, and still the same excellent quality. Some regular micrometers also have a vernier scale for measuring to .0001".
A machinist taught me to always check that the caliper reads zero when closed. If it does not read zero, then it is likely that there are tiny metal chips on the jaws. Also the zero on a dial caliper can be adjusted by loosening a set screw and turning the dial face slightly.
4:45 - I have been using this type of caliper for many years and have known all but one of the features of the tool you've shown in this post. The one I just now learned from you is how to use the notch in the depth rod and it make perfect sense: for flat bottom holes, place the gap along the wall of the hole; for conical or pointed bottom holes, place the gap away from the wall of the hole. Thank you for providing detail on the usage of this versatile tool!
There are also calipers with a dial, I have a Swiss-made Tesa accurate to 0.02 mm. Otherwise, the CE = China Export story is just an urban legend, there is even a section about this in the Wikipedia article on CE marking. In any case, the CE marking is only a sworn statement made by the manufacturer, not a certification mark.
@@blechtic Once again, this is not a certification mark, it is solely under the responsibility of the manufacturer. Also, they are calipers, there's no safety risk involved... Regulation (EC) No 765/2008, article 30: 1. The CE marking shall be affixed only by the manufacturer or his authorised representative. 3. By affixing or having affixed the CE marking, the manufacturer indicates that he takes responsibility for the conformity of the product with all applicable requirements set out in the relevant Community harmonisation legislation providing for its affixing.
Thank you! I have had a set of digital callipers for YEARS and didn't know about the depth or step measurement options! This is going to make my model making so much more accurate! :)
My father was a master machinist. His children were raised with micrometers and dial-indicator verniers, working on iron cast machines. There was no CNC. If you lost your zero working on a job, you were basically screwed. This was about 1972. Today, computer control makes these tasks quite a bit easier. My father taught me never to store the verniers completely closed, and never slam the verniers closed, as a sudden impact might affect the accuracy of the instrument. I still have a pair or two of the old dial-indicator verniers. They are still accurate, and I use them for my woodworking.
I've been in QC for 45 years and that's one of the first things I learned but it's even more important with 0-1" micrometers and never leave gage blocks wrung together. All it takes is the right amount of moisture and they fuse together. I have seen it happen more than once and even if you can get them apart the gauge surfaces are pretty much ruined for any true precision usage.
@@robertc8134 : Your father would have collapsed in shock if he had seen me trying to use a Vernier caliper as a wrench! I was pre-school aged. My father spotted me in time to avoid disaster, but I did get reminded for many years afterwards! 🥴
I was a metrologists for many years and find the video informative. The real test comes at the hands of an experienced machinist. Technique is everything!
Thanx for the review, and the reminders and the "new" info. My father was a Civil Engineer and he taught me to read the Vernier scale on his K&E Mountaineer Transit when I was about 14 years old. I still have the pocket magnifying glass he gave me to make it easier to read.
I have the 530-104 Mitutoyo calipers. Back when i started engineering school, my dad had an older pair of Mitutoyo's i could use. I loved them, and when *HE* lost them (unknowingly) and blamed me for it, i gifted him the 530-104. ... Then he found his old calipers at the bottom of his toolbox, and he hasn't stopped apologizing since. He gave me back those gifted calipers as an apology. (at my own literal expense :P) In school, everyone had digital calipers. Except for me. And i couldn't have been happier. Say what you will about digital. It works, it has its benefits... But it also replaces a lot of hardware it doesn't need to, and ends up inducing error or reliability problems that doesn't belong there. Analog will fail you when you break it. Digital will fail you when it breaks. The difference is small, but measurable. Well, _given the right tool of course. ;)_
@@mikewatson4644 And almost all of you couldn't drive a Model T Ford because technology has surpassed the need to know how. No one needs a slide rule now except to measure their black and white RCA picture tube and find some weird level of superiority over those that couldn't care less.
@@booifojoe Can't agree with that. i am a retired pilot and we use(d) circular slide rules. We called them 'whiz wheels' and they are easy to carry, cheap, reliable, rugged and can do all kinds of calculations. Not sure i've seen a calculator for doing that but there may be. The vid was amazing as i had no idea about the finer points
@@booifojoe There are lots of slightly modified slide rules used for things today. For example, there is one that is used for calculating how much concrete is required for a slab. I was helping to pour a rather large slab recently (required 5 truck loads) and we were getting down to needing the last load. We measured the area that was left. 1 guy pulled out his cell phone and started to use the calculator. Another guy pulled out the modified slide rule and started to slide the dial around. I did it in my head and beat both of them. To be fair, I had a head start because I started to figure as soon as we started to measure.
In tradeschool they would only let us use vernier scale calipers and conventional micrometers. Nowadays I work in a high volume CNC machine shop, we only use digital everything. At home I use the midground between vernier and digital, dial calipers. Easier on the eyes than vernier and doesn't need batteries.
It's an urban myth that's hard to kill. It was all over the European tec community 15 years ago. It's been debunked a lot of times, even in the European Parliament. Links to debunk on the Wikipedia page en.m.wikipedia.org/wiki/CE_marking
@@nilshagness8055 It's hard to kill because you always end up with some new person with an audience thinking its real. It is incredibly ironic that this is a growing problem in the information age where information is more readily available, but apparently so is misinformation.
Still rocking the dial Starret vernier caliper. Those and the Mitotoyu 0-1, 1-2 and 2-3" mics set are still going strong after 40 years. Buy good tools and take care of them and service when needed and they will last a lifetime.
2:50 The advantage of digital calipes is that i can read the numbers without using glasses as thick as bottle bottoms. Becoming old is a hard business ^^
Working in Machining since the early 70's this is a great video. I have used Vernier Calipers that were 3 and 4 feet long. Still own 12 " ones. This all we had at one time.
5:28 dam. i learned something today. i have always used the depth end to measure steps. now i just need to keep that in mind when next time using calibers
1:10 I recently did a project where I made a large number of accurate measurements using calipers, both digital and vernier. In the end I switched to digital calipers because it reduced the mental labour required.
That was the best explanation on calipers I have seen. I bought a digital calipers but always afraid to use it because of the lack of any knowledge. Now I have an idea I can now at least try out using mine to learn and rewatch your video to compare what I found and what I may not have correct. Brilliant job
Thank you very much! As a student, I had a choice of Marching Band or Shop. I was in the Band and missed out on loads of vital skills. I have frequently found myself in my shop attempting to solve the puzzle of accurate measurement. This video is clear, concise, and extremely helpful in understanding the proper use of my calipers!
I like my Mitutoyo digital calipers. The action feels smooth and the battery lasts a really long time in them compared to cheap chinese calipers. I really like dial calipers but I've had the rack and pinion mechanism fail due to debris ingress. There's nothing to go wrong on vernier calipers, as long as you can read them.
What an awesome channel! Crisp and detailed information precisely explained. That is pretty rare nowadays. Thanks for the great job and keep up the good work.
Pretty nice tutorial. I never used a Vernier Caliper much but I still have my Starrett dial calipers. 40 years and still working perfectly. If I had known how it operated i might have used one instead. simple durable and your battery won't die at the worst possible time.
Not to mention that digital calipers are essentially automatic reading verniers that use varianle capacitors on the slider caused by alternative conductive and isolating strips on the ruler (under the label). Electronoob's video on digital calipers was really inspiring
Excellent Instructional Video!!! Quick and to the point. My only criticism being the fact that some parts are quite vague offering minimal information, however, as a whole, this is a highly efficient and an excellent piece of work. Thank you for making it available to the community.
I was in a technical school more than 40 years ago before the digital age caught on. We learned to read verniers and micrometres and how to set up and use shapers. The new thing for me is step measurement. Nowadays you are the man if you can program CNC.
I didn't think I could learn something new from this video, but the step measuring was new to me. I just used the depth measure to measure steps. Great and informative video, keep up the good work
Thanks for this info. The step measurement was also new to me. I also prefer the vernier calipers, as my digital one burns through the battery quickly.
China Export calipers are usually (electrically) very bad designed and use 1 battery per 3 months (if you are lucky). I invested in a Mitutoyo 10 years ago and never have had to replace the battery...
WOWZA!!! Like others, I thought I knew how to both read and use a Caliper. I did not, until now! Most excellent! I am sending to many gearhead friends. Good job.
For years I used digital calipers for 3D Printing and CAD but it always struggled to geht designs to fit vor geht accurate prints. Two years ago I bought a analog one and instantly everything fits perfect first time. Comparing the analog with the digital it is a huge difference in accuarcy and consistency
Did you just have a cheap digital? There isn't a really good reason for digital to be more/less accurate (it actually just uses a conductive vernier scale on the back to measure)
I use calipers daily and I'm a little amazed that we aren't introduced to them in school. I use everything from cheap plastic verniers (for times when damaging the caliper is a real possibility and high precision isn't critical) to our usual cast of characters. I usually grab dial calipers since it's relatively easy to read and doesn't take batteries. Next is vernier -- again, the battery thing. I usually only go digital if 1) I have batteries since it's probably gone dead since the last time I used it; 2) I have a lot of things to measure since reading the screen is so much easier. All are used and useful.
I was taught how to use a Vernier caliper (and Slide-rule) at school... admittedly that was more than sixty years ago. These days, that lesson has probably been replaced by "How to use an Electon Microscope"! 😜
@@PiefacePete46 lol. Know what you mean. I was the last slide rule practitioner at my school. I had to stop when they 1) requested more than 3-1/2 digits of precision; and 2) stopped allowing log and trig tables for test taking. Ti-30 to the rescue. Nowadays I just use the 'rule on my desk for funzies when I feel like going old school.
@@terpcj : We are talking about everday items from not too long ago that todays youngsters could puzzle over for hours! Not long after I left school I worked as an aircraft Load Controller. The balance of the aircraft was calculated with a rudimentary Circular Slide Rule... Today, Google would probably work it all out for me if I asked nicely! 😜 I still have a slide rule in the drawer behind me... I must check it out for a giggle.
Do please continue to show us usefull things and details that are hard or time consuming to find out. That is a automatic like and comment from me every time!
I think this is the best video I've seen on using these tools properly. 🙂👍 I use the Vernier Calipers in Locksport and although I've used them reasonably right, but now I realise that I need to tweak how I use them. Like many others I thought the calipers that were non digital were nowhere near as accurate, thanks for clearing that up 🙂👍
I remember... I seem to recall they had "Switzerland" as well, for "Made in Switzerland" watches. They also added one jewel, so watches could have "Jewelled Movement" printed on the face. The solution to that was that watch faces had to say how many jewels were in the movement... The answer to that rule was watches with "0 Jewels" on the face! Of course it was only a matter of time before Japan moved on from this nonsense, and started producing some stunning high-class products. "Made in Japan" no longer had a stigma attached to it... I guess China will follow this path very quickly.
@@PiefacePete46 What I've learned is that the "NO (0) JEWELS INSIDE" was put there on watches with non-jeweled movements to avoid the higher import duties for jeweled movements put in place to make customers choose domestic watchmakers.
@@ZacabebOTG : That makes sense. My version came from my father... it could easily have been his own interpretation, or a story being spread at the time. "Misinformation" is not as new as we think! 😉
@@PiefacePete46I don’t think Chinese companies need to really care about the quality of their products. They have much less competition than Japan did and operate primarily in environments that reward deception, like Amazon’s marketplace.
Worth watching even if you thought you knew all about calipers. The CE issue was the best explanation I've seen, and I now need to go and check all my stuff!
The whole China Export myth has been debunked already but it keeps popping up. The CE marking on products manufactured in China actually corresponds to the European CE marking required on some products but it looks different due to changes in dimensions and typography. There is no official CE logo specification. Also, the European CE marking only indicates (but is not proof!) that the manufacturer claims to have passed the required quality controls (which is always the responsibility of the manufacturer). This is often the case but not always. And the reason they put the CE logo on there is because the European Union demands that for a whole slew of products that manufacturers want to sell in Europe. Just search for it and they are easy to find.
"There is no official CE logo specification." Actually, there is a very specific set of criteria for its relative dimensions. And length over all can't be shorter than 5 mm. (in those cases it can be printed on the packaging and/or instruction manual, or other documentation if applicable.) It is literally part of the CE directive itself. However, the requirement that the two circles should overlap has been misunderstood by a few manufacturers that has ended up printing it incorrectly. One being Microsoft, having the compressed (and thereby incorrect) version on their wireless Xbox 360 controllers.
Most electronic versions even turn off . Still use a tiny bit of battery life. So if used infrequently. Pull out the battery. Ready to put back in the next time you need it. Nothing worse trying to use it , only to find the dead battery.
Great guide on how to use the very versatile calipers! Straight to the point with clear explanations. The step measurement was new to me. I've been using the depth guage, but it's sometimes hard to get it straight. And if there is a slight gap in the step, the very slim guage can slip under it.
Calipers are a Must Have Precision Tool for Everyone. You didn't show a dial caliper, which are great for reading ease and no battery (I'm still using the Brown and Sharpes from 1983). The downside with dial calipers is that they are either metric or standard. I'm sorry but standard vernier calipers are too time consuming and difficult for new users. My favorite calipers are 8" Mitutoyo Digital, they are super smooth and accurate. The batteries last 1 to 3 years depending on use. Great video ;keep up the good work. I'm a retired tool and die maker from Honda.
Hi James, just what I have been looking for as confirmation of how to use a set of calipers - absolutely brilliant, thank you so much! A friend told me how to use them, but I never quantified his advice, you have just done it!! An absolutely great, no nonsense video with clear and concise information and advice (esp the bit about Chinese made rubbish). Many thanks. Regards from the UK.
Kids these days. They need internet for everything. There are few tricks he doesn't know tho. Meme about young generations: "when you have a smartphone, but you're not smart".
@@GrandePunto8V The older generation had to learn from somebody too, unless you are inventing everything you use yourself. Like Issac Newton said, "If I have seen further it is by standing on the shoulders of Giants". The only difference between the older generation and the younger generation in the learning category is that the younger generation have a lot more people to learn from thanks to the internet, which generally would make people smarter. But young people are always reticent to heed the advice of the old.
I’ve had a set of Mitutoyo calipers for about 25 years. They still have no play in the jaws and were used extensively during my time working as a mechanic on heavy machinery. I’ve been retired for 10 years but still use my vernier calipers all the time in my home workshop as well as a Mitutoyo 0-1 inch micrometer for really accurate measurements. I was brought up using inches but systems changed to metric in my younger days. I still like to measure fine measurements in thousands of an inch rather than using my metric mics.
Before this video, I didn't know about the depth measurement possibility at all! I have a $10 AliExpress digital caliper for home use and it has always served me well. Thank you for a very informative video.
Using vernier calipers is the only time I actually appreciate being near-sighted. Once those glasses come off, my eyes have magnification built in... ^.^
Yeah but the accuracy comes down to users eyesight. Let's say digital is more accurate in that the number displayed is the number you use, where as with verniers you could be out because you couldn't quite see a distinction between which line was closer.
I dropped and bent my Vernier callipers so I thought I'd splash out on a pair of digitals , I now wish I'd bought another pair of Verniers , the battery doesn't run out when you need it most . I will be buying a Vernier and a dial calliper next .
There was a joke from half a century ago that claimed that (Japan) (China) had named a city "Usa" so they could honestly say it was "Made in USA". Now they're doing it. Sigh.
I use a dial indicator caliper and I love that tool. The cheap digital ones don't have proper power management when turned off, so your battery will not last long. Even the proper CE label only means that the manufacturer claims that it conforms to the standards given, but no one ever checks it, so you need to trust every Chinese backyard shop not to lie about it. IMHO, it's completely useless.
Suggestion for the presenter: If you're pointing at very fine lines (such as what is inscribed on a caliper) avoid using your finger (which is a couple of orders of magnitude thicker than the lines). Instead, using something of similar fineness, such as a sharp pencil or the tip of a pen. Thanks.
I got an education on how to use calibres. I just use them for my guitars' nut measures & model railroading coupler mounting. Never knew you can use for so much more, Thank you.
What amuses me is the price range of calipers. A 12-inch caliper can run anywhere from under $20 to over $1,000. While the $1,000 caliper is extremely accurate and precise, the $20 caliper is still good to 0.001" and suffices for most applications. To be told, I do have a number of high dollar, high accuracy and precision instruments, but they are not used every day and are primarily used for inspection. Needless to say, no one touches them but me. Did you know that if you are trying to do high precision work, how you hold your measuring instruments can affect their accuracy.
Yes and a 1 or 2 degree temp change from inside machine check to outside on table changes size and reading and calipers good to .005 or more anything smaller needs mics. Have indicators and mics down to .00001
2:07 Holy crap! This is high-value info here. I don't pull out the calipers often, and when I do it's a digital caliper but after this video that my change. Digital calipers are frustrating and finicky at times, at least mine are, but I've put up with them due to my belief their accuracy and general ease of use outweighed their flaws. What I learned from this video in just the first 2.5 minutes has changed my mind. And made me hate button batteries even more!
Also take a look at dial calipers, they're my favorite type of calipers, but a bit harder to find. They're faster to read than Vernier calipers, but still no batteries.
very handy, I did not know about the step measurement. I'd been measuring things using the very tip mostly- I'll be using the base now, I'm surprised I didn't reason that out on my own. That CE detail will come in handy for all sorts of stuff too. Great vid!
One thing i dont like to see is when people use a vernier caliper as a marking out gauge. I have seen people scribe lines on a rotating part thats rotating in the lathe chuck.
@@grandpasbarn2806 But if you do that you still show that you don't respect your tools. Why would anyone use any fine instrument (or even a cheaper one) to a job it wasn't intended to be used for (Scribing marks on the work piece).
Hey man, having learnt micromechanics in switzerland, you are acurrate in every way wich is nice to see for once, and you even confirmed a few things that i was pretty sure about but that i know anyone else could have known about. Great video, i hope you keep going in educational material like that. Best of luck to you !
