Hi folks,

Can anyone tell me what the typical accuracy of a decent pair of vernier
calipers is (when used carefully and correctly)? I just bought a dial
bore gauge and am wondering if I can reasonably set the zero point with
vernier calipers instead of having to buy a 3" to 4" micrometer. The
calipers are Etalon brand, heavy and made in Switzerland. The bore gauge
dial is graduated down to 0.0005". I'm not reboring an engine, I just
want an idea of the wear, so I don't need the highest accuracy. From
using these calipers, my own guess is that they're probably good to
0.002", but some of that might be my errors in reading them. I'd be
interested to hear what other people think.

Best wishes,

Chris
