Dial Caliper?

[papajoe222]

I saw the need for another caliper and decided to go 'old school' and get a dial vs. digital. My question is how exactly does one read the measurement? I read this as .334. Is that correct?

 

[geo.ulrich]

yes sir thats correct

That's not OLD SCHOOL !!!!!
Get a set of vernier calipers and learn to read them.
That's OLD SCHOOL LOL.

It's gets easier with experience but even after all these years I double check myself.

 

[DShortt]

After a second look and not knowing the picture angle I'd be inclined to call that .3345.

Someone will probably be along directly to tell us how obtuse I am.

 

[DShortt]

.3335. Guilty as charged.

I've been using a Lyman vernier caliper that looks to be identical to yours for . . . at least 3 decades. I love it.

There's something about a precise, beautifully-engineered yet simple mechanical device that I find irresistible.

That is a dial caliper, not a vernier caliper. This is a vernier caliper. Picture from Wikipedia.

Using that one is also an eye sight test.

Next thing we'll talking about slide rules.

Now that’s a true relic. I have one stuck somewhere, but it has been since I was in Physics Class as a senior in high school that I used it.

I do not care for electronic mic’s or calipers. I’m not old school. I just don’t like them.

Parallax is a PITA for dials, so learn that well to not fool yourself. Know what angle you are looking at, even as the dial moves across the face

The official method for reading anything with ticks is that you can do 0, 1, or half. The image above is 3.335. Can't be 3.334 because not a valid measure for a machine-era measuring system.

When you get really, really, realllllly experienced at it, you can start trying for subsidiary fractions, but not everyone gets there.

I still have one from back in the 1960's.
Three (3) significant figures of accuracy at best.
That was good enough to send men to the moon and build nuclear reactors

I use the dial calipers mostly but do have a digital laying around somewhere, at the rate my eyesight has degraded I’ll be needing it soon enough.

 

[dave@aDave]

I believe the actual reading is 0.340.
The gray line on the dial is the needle's shadow from the light

lol .340 and the needle would be down there over the 40

I think you found that first 3 on the computer keyboard. I don't see it in the picture.
Computers are the real PITA.

I stole the pic but it's what I was using in my early day's.

Yep had these right here in my desk . Still use them everyday . I'm in the steel and machining buis.
