Vernier Calipers... *LINK*

Dangit Rob, you shouldn't have done that...

>The more people who remain ignorant of how to use vernier calipers the better. I never could keep digital calipers at work - they always walked away. Verniers stay put because only machinists and old timers know how to read them.

>I have a K & E Paragon Jr. drafting arm that uses a vernier scale for setting angles. I still like them as there is a lot less to go wrong. (and no batteries to go dead;-))

>Pretty slick applet, Rob. It has been 25 years since I have used a vernier caliper (used to be a gearhead), and I was a little foggy on it.

So, got any nice calipers for sale? ;-)

>Very cool! Thanks for posting this. I always wondered how to read them. Now for a potentially embarrassing and probably completely stupid question: Can some one direct me to a resource that will tell me how to read a caliper graduated in thousands of an inch? I don't have any background or training in this sort of thing so I could use all the help I can get reading calipers, dial indicators, etc.

Not even all machinists, necessarily

>My younger son took one machine shop course at the community college and never went back because the instructor couldn't answer any questions about how to do things that didn't involve electronic measuring devices and CNC machinery. He figured out how to use his great-uncle's lathe (about 2-1/2 times older than he is) more or less by himself.

Cooll site and...

>Also guys you can use a set of dial calipers also. Not that much more $$. No batteries to dead replace and eaiser to read too.

>Brian -

For a dial caliper, you generally have to read from two or more places...

With many calipers graduated in thousands -

Read the "tenths" from the caliper beam, the "hundredths" from the major dial divisions, and the "thousandths" from the minor dial divisions...

I.e - read 1.2" from the beam, and .028 from the dial.... 1.228" total.

Cheers -

>... the same as for a vernier...

Read from the beam first, add the corresponding last digit(s) from the vernier scale...

>I've got an older vernier caliper that is graduated in quarters, eighths, sixteenths,and thirty-seconds. I love it, even if I haven't figured it out yet (it has this in common with my wife). I am familiar with how to work the inch-and-hundredths feature on 'normal' calipers, but I'm a little puzzled by this one. Anyway, I figure if I'm measuring that closely I shouldn't be doing it on wood. Mostly I use the bar measurements, or ignore the units altogether and use the measurement directly off the tool.

-who also has a 'regular' vernier, and a dial caliper that reads in inches and another in cm/mm that all get used a *lot* less than the 'odd' one.
