    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.

        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.

        If you already knew this expression, here is chapter two:

        Account for the width of the blade.

        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.
