Another dying skill?

[Munroast]

Venier or Vernier Scale is a clever little scale that helps identify small measurements more easily

I would call the ones in your image "Vernier Calipers" where the ones in mine are the Vernier Micrometers (Micrometers with a vernier gauge)

When either have digital readout then they are digital calipers or digital mirometeres - even though folk insist on calling them "Vernier"


look at this stupid advert - there is no verier scale so they can't be vernier calipers !

Draw filing. I was taught to do that to heads and blocks on commercial vehicles as an apprentice in a Vauxhall/Bedford main dealer. Never seen or heard of anyone else doing it.

seems utterly mad - what happens if the file is slightly bowed ?
and the way he was doing it was asking for trouble, pushing down over fresh air on either side - no wonder he was just removing material from the edge. (those files don't flex much, but they do flex)

I'm sure you could achieve an improvement with a manual approach - but not like that, wet and dry stuck on some very thick plate glass ?

I'm with Motties post on the Micrometer and Vernier. I'm surprised no-one has mentioned the ' pocket bible' we all carried in our boilersuit pockets back in the day :- Zeus charts. ( bet there's loads looking that up now )

I have one in my garage ready for consultation at a moments notice. You can get them online now, progress eh!

Ssshhh

And I wondered if being able to read a Vernier scale is now a dying, soon to be extinct, skill, in the same way that using a slide rule became?

Vernier use is still being taught at an undergrad level at my old place - used more or less exclusively with travelling microscopes, or with those students needing to machine in the mechanical workshops.
It's not a skill that's dieing yet, but there is resistance from students to use these measuring tools, when digital readouts are available.

Made a couple of crossbows in school , does that count?

You should check out Joerg Sprave's Slingshot Channel on YouTube - he's made some interesting crossbows. He also reviews commercial ones.

Invented by M. Pierre Vernier almost 400 years ago.

The batteries in Vernier gauges don't go flat.

The batteries in Vernier gauges don't go flat.

Nor does the slide rule

Or the log & conversion tables

thats true, but the batteries that focus my eyes seem to have went a bit flat - need my extra strong glasses on to read the dam things

Indeed, and nor do they 'go wrong' ...

I still have vernier calipers, vernier micrometers and other vernier-based things and although I'd like to think I can/could use them today, I generally don't, since I now have equivalents with digital readouts.

I bought a (very cheap) 'digital' calliper a good few years back, and have been using that ever since. In the case of my vernier callipers, the only thing that can/could possibly 'go wrong' with it would relate to 'human error'. However, just a few weeks ago, something went wrong with the digital one which resulted in it displaying figures exactly double what they should be. Had I not been able to apply common sense and 'experience' (e.g. knowledge of the visual difference between, say 10mm and 20mm, I could have been mislead!
