Wow! That’s a creative way to use a caliper.
That’s why teaching children about metrology basics is so important.I remember when I first applied for a job in a fabrication/machine shop. One of the questions in the interview was “Do you know how to read a tape measure‽” followed by “demonstrate that you can use a tape measure” along with some other fun ones like “what is the difference between these two pieces of material” (one was aluminum, the other stainless) and other such things. I remember being surprised/disappointed that there were grown people who couldn’t read a tape measure.
I’ve worked in machine shops and drafting offices for years now, and I’m no longer surprised by people who can’t use basic measuring tools. Still disappointed though.
There’s a great test for programmers called FizzBuzz. It’s an extremely easy task - print some numbers (maybe 1 to 100), but replace them with Fizz if they’re divisible by 3, by Buzz if they’re divisible by 5, or by FizzBuzz if they’re both.
Many reasonable people consider it way too easy - if you can write this, it doesn’t mean that you can write complex programs, or that you know the applicable languages, or that you know anything about the business domain.
But interviewers know that it’s a great test because a lot of so-called programmers still fail it.
We did a fizzbuzz interview with a candidate. He passed but I had a weird feeling about it so we asked him to do another one with 7 and 21 and he couldn’t do it even with his old code right there
Damn, dude managed to literally memorize code without having any idea of what was going on. Meanwhile, I’d spend most of my time trying to figure whether it’s div or mod that i’m supposed to use to check for the remainder of a division, I always forget which is which
Omg!
Oh I could see how that would trap someone. It would trap me but I’m not a programmer. 😆

It’s good for a young dev IMO because that problem has many solutions and shows the programming style of the dev as well. But I agree that having a problem that is related to the actual work is better.
It is great because it allows you to eliminate bad candidates very quickly. It can’t be the only test, but it’s very useful as the first one.
I very much prefer every product of multiplication of 9 up to 3000 in a descending order.
Ypu get to see a lot more than the fizzbuzz. And still very easy task. Then you can ask about processing and memory optimizations.
OK - now I’m curious, what were the most common mistakes people made reading a tape measurer? Because I’m having trouble working out how someone could screw that up lol
We had a guy we called “10/16” (ten sixteenths) because he was told to grab some 5/8" (0.625" or 16mm) steel plate, but he couldn’t find any he could only find 10/16" and 12/16".
People will count the little lines on the tape and not remember if they are 1/32, 1/16, or 1/8.
I think metric would help this.
Oh OK - that does make a bit more sense. Still not exactly Nobel prize material, but fucking up the fractions at least makes more sense than not knowing how to read numbers and count lines lol
Metric would help with everything lol. I dream of the day we finally make the switch
Yeah, fractions are dumb. Or I’m dumb and fractions are easy, but why don’t we split the difference and switch to metric?

I worked with a girl who would say “4 and 3 ticks!” meaning 1/8ths. We laughed at her enough that she tried to improve and started saying “4 point 3!” that lead to a discussion about decimal inches. I really blew her mind when I showed her the scale in 12ths on carpenter squares.
Some people dont know why the metal bit riveted to the end moves…
Or they even say this is a sign of wear and means you should throw it out.
And because I enjoy sharing knowledge more than boasting I know more than others: the reason it moves is to account for the thickness of the metal hook itself.
It makes a difference if you are hooking it onto the back of something and measuring from there, OR butting it up onto something and measuring from there.
If you want accurate and consistent readings in both of these situations, the hook has to move. It basically pivots around the true point you’re measuring from.
Everywhere I’ve worked, you’d “burn an inch” or “burn a foot” meaning you don’t use the metal tab, you hold the 1" or 1’ mark at the start and measure from there.
Measure twice cut once is a saying for a reason.
If you already knew this expression, here is chapter two:
Account for the width of the blade.
Ahh our good friend, kerf!
For years I just drew a line and then sawed down the middle of it. 🙄
At least for me, that has more to do with misremembering what I measured than mismeasuring it
Can’t count how many times I the workshop I measured something, made a mental note of it, walked back to the workbench, only to have to walk back and remeasure it because now I’ve forgotten what I just measured lol
I got in the habit of writing that shit down on scraps of paper or wood. And then, of course, I got in the habit of dropping those scraps of paper or wood into the growing pile of scraps of paper or wood back in my shop and picking up the wrong one when it came time to cut.
And this is why I always have a bunch of marking and numbers and other vandalism on whatever board or piece of material I’m using.
“what is the difference between these two pieces of material” (one was aluminum, the other stainless)
Did they expect you to identify which metals they were, or just that they were different metals?
I was expected to know that one was stainless steel and the other was aluminum, but not the specific grades of stainless or aluminum. Stainless and aluminum can look very similar when they’re dirty, and 300 series stainless won’t stick to a magnet just like aluminum won’t stick to a magnet. But if you pick them up or even rap on them with your knuckles you can tell the difference.
After having a customer chew us out for something that wasn’t our fault he had us follow him to another room to discuss some more work. He borrows my tape measure and tries to measure something on the wall and the tape keeps falling over and flexing. It finally hits him in the face and hands it back to me and says “I’m not familiar with this type of tool”. I think he saw our faces turn red and eyes water up as we were trying SOOO hard not to laugh.
I want to wholeheartedly believe the caliper has the size the customer wants and the pipe is bigger, therefore inappropriate. I’ve never met anyone who would use a caliper this way, I’ve seen people trying to eyeball it or use it as a ruler but not like this
Oh jeebus fucking christ. Sometimes the dumb hurts and then you get the existential dread knowing you’re about to have to call this moron. And, even better, they usually make more money than you.
Ikr, should’ve pushed them all the way in so it’s a repeatable measurement ffs.
Anyone who works with clients can appreciate this one
Next time, chose a smarter client.
They don’t exist.
Bold claim, also very true
I am a certified blithering idiot and even I feel like a high society intellectual compared to this picture.
Two of them did this.
Just for the fun of it: i’m making it 3 in my head. 1 extra to take the photo.
Probably. And not one said “hey, thats not the full dimension of the hole”.
please close and reverse the tool, then grip it tightly and drive it into the skull of the complaining customer
Judging by this, even if it’s the right size, they’ll probably install it wrong anyway, so why bother?
I hate that I have blurted this out during meetings before.
They were trying to design a caliper holder that fits the jaws in that orientation, obviously. They need to fix this, send it back.
A normal set of calipers has 3 basic modes of measuring things: inside, outside, and depth. It is amazing to me how many people in this thread don’t know at least one of those or use them wrong.
Til the calipers I use, almost daily, can measure depth. Now I’m less annoyed about the stick protruding from the end lmao
Haha same.
Tbf I use mine daily and had to pause a second thinking what would be the third mode. (never use it to measure depth)
At least it makes me feel good that I only just got a set for the first time last week and figured all those out within 5 min of actually using them.
You can also use the top back side to measure steps. It’s more precise than using the depth gauge.
What? Tell me more!
Tbf people my age and younger (barely below 1/2 the population) typically don’t use them in most careers or even learn about calipers in High School. My work was the first place that properly taught me how to measure internal diameter and depth.
So these guys are smart enough to read Vernier calipers, but dumb enough to measure like this?
Tbf it’s simple substraction
Must’ve forced a facepalming intern
Showed this pic to my co workers (steelworkers/blacksmiths) and only the old guys knew what was funny about the pic… Gen z think that calipers are toy guns…
I use calipers frequently and didn’t realize it was upsidedown until reading this.
I thought it was a joke about clients always sending shitty low resolution pictures where you can’t actually verify their claim.
Oh, I thought the joke was that the hole the customer was complaining about was the hole this pipe was supposed to fit into, and that they were measuring the inner diameter rather than the outer.
The joke is they’re supposed to use the end with the spiky bits to measure the inner diameter of the pipe. It’s even more baffling they’re using a mechanical readout when a digital display would be easier to measure with IMO.
I dunno, a lot of gen z and millennials probably use them when fabricating parts for things that you can’t get them for. I know I do for my printer.
Well… im an old millennial and know what it is and how to use it properly…
I feel like a boomer/millenial trapped in a young body when I read stuff like this 😭
How do gen z-ers measure distances finely, then?
Realistically, how many people need calipers in their life? The vast majority never used one because a ruler or tape is enough for pretty much anything in a house.
Looks like that hole chamfer is wrong. Doesn’t properly fit the measuring device.
