Would you prefer it was moved to the Grumpy Old Bugger thread? What's wrong with a bit of fun?

Possibly it's an advanced caliper piston pusher....

I think in this instance a younger less chilled out me would have written

I would happily hedge to win or loss knowing that

I was “right and justified”


Now I’m old and jaded id just tick a and move on

Dunno, just found it on the net and threw it up for ****s and giggles.

I assume it’s meant to show that most don’t take the time to check the detail.

First look I didn’t realize it had six segments instead of five.

It looked close enough to three which match the answers.

as expected some put the serious hat on…..

Had some fun in other across the globe with out North American colleagues given it was in metric. And other that had never had to work out the scaling on a micrometer.

Not all Gav, I assumed it was a diagram, if it was supposed to be a micrometer I'd have used it as a G clamp as it's not much use for anything else

Image 1. The 0.5mm marks on the barrel are incorrectly spaced, there are 5 divisions between major units on the thimble.
Image 2. The 0.5mm marks on the barrel are correctly spaced, there are 5 divisions between major units on the thimble.
Image 3. The 0.5mm marks on the barrel are correctly spaced, there are 4 divisions between the major units on the thimble

Good googling…..image 2 would be the correct on for teaching or testing.

Sure had the desired effect

You're right! The most accurate caliper piston pusher on the market!
