Digital verniers

[Brian GParticipant @briang]

Is it time to accept that our language has changed over time, and accept that these sophisticated (but in which meaning?) calipers are called "verniers"? We could always go back to an older usage, still used in German, and call the Vernier scale a "nonius".

Perhaps we could then turn on Mitutoyo who use the term "Digital Micrometer" to describe their QuickMike, despite it using a linear scale instead of a micrometer thread? Should however Mitutoyo decide to give me one of these instruments, I would happily use the same argument in their defence

Digital verniers & digital rules are rare beasts indeed and about as useful as a digital sundial 😁

If you wander off to Thingiverse you will find plenty of designs to 3D print you own Digital Sundial.

On thingiverse you can probably also find things like a spring loaded bum wiper along with a laser fly swatter a solar powered torch and many more useless things that mankind doesn’t need .

All of those are just digital clocks that cast a shadow and how does it work in the dark ?
Now a really classy unit could be  made using a gps clock and a laser pointer on a classic sundial face and wouldn’t that make a different clock ! When it is dark a laser dot or line shows the time and when it is daytime it uses a shadow .

Now please tell me you own a rubber surface plate 😂

Haven't got round to one of those yet but I have some precision 3D printed V-Blocks

Someone on the net was selling a Time Projector on the net a year or so back. There were some people I'd've liked to project through time, so I thought about it for a while…

Just for fun, here's a real Vernier Caliper:

I've covered up the millimetre scale because that's too easy, but what's this vernier reading in inches?

[I.M. OUTAHEREParticipant @i-m-outahere]

29/32 ?

That is one weird vernier  – well it is to me anyways !

125/128" or .977" to the nearest thou from the Vernier scale, but the tape measure value doesn't make much sense against that. Unless it's in Arshins and Vershoks or summat…

Could it be a patternmaker's shrink rule?

Well went to booty this morning & spent £35 on this lot. Well pleased. pic 2& 3 can you decipher for me. Pic 4 anyone got an idea what this is. Have not got a clue what it is but it has a fancy screw & a rack that traverses vertical & horizontal. Thought I might be able to adapt it to do fine work on rings. He charged me £3 for it. Just had to have it.

Simply eighths, sixteenths, thirty seconds and sixty fourths in decimal format. No idea what 4 is, but probably off some sort of scientific instrument.

No 4 almost certainly from a microscope stage. Possibly Vickers looking at the shape.

An essential piece of kit for some! And why waste time 3D printing when you can get one for as little as £5.95 with VAT relief!

Sorry – but I ended up on that page at random yesterday looking for ways to store cables without tangling them.

@Michael Gilligan could tell you and might even make an offer for it.

It's a micro-adjuster for microscope slides, fits on the stage of the scope, the curved arm at the top holds the slide secure in the corner. You can move the slide very accurately to take exact measurements.

I suspect optical distortion – the exterior jaws of the caliper measure about 30 1/2 mm on my screen, whilst the inside nibs appear under 28, yet if the scales in inches the reading is undoubtedly in 128ths as there are 8 of these in a 16th, and there are 16 divisions between the 1 and the 2.

I've seen 128th Verniers often at junk tool stalls on flea markets etc., which IMO is the best place for 'em. I certainly can't imagine anyone ever actually using one, except maybe to mark up carpentry timber in whole inches or major fractions.

Oh, and setting conundrums to see if folk actually understand how to read such a scale.

No need for my input, Neil … Your description is adequate.

This type is usually known as an “attachable mechanical stage” … because it’s ‘bolt on goody’ to upgrade a plain stage. There’s a lot of good engineering there for £3.

[Stevie] If the action is stiff; thin the solidified grease down a little with ‘PlusGas formula A’ or similar … to save damaging the mechanism.

Edit: You will note, of course, that there are Vernier scales on both axes.

Correct as it does say Vickers instruments on a plate. The guy did say something about a Microscope.

Michael. The action is super smooth. I walked past it several times & kept going back for another look. My brain was going 10 to the dozen thinking what could i do with that. It was so well engineered it had to come home with me anyway. I am going to make some Mandrels to hold rings in the lathe. I thought of making up some way of mounting it to the cross or top slide, so I could hold small tools very accurately.

That’s a great buy then, Steve

But, unless you are doing very light work, I would advise against holding lathe tools on it.

There is no locking on the slides, and the gearing is light duty

… remember, this is designed for accurately moving a little 3” x 1” sheet of glass.

Sorry, I haven’t yet identified the manufacturer … but if you could provide a few more photos, I might.

[Michael GilliganParticipant @michaelgilligan61133]

Just read back, and found mention of Vickers Instruments

Sorry … I responded to Neil’s post rather than Steve’s

Vickers absorbed both ‘Baker’ and ‘Cooke Troughton & Simms’ … so there is still a bit of detective work required.
