Micrometer Or Digital Vernier

[The Old One]

Which one should I buy?
It will only be used for measuring cam shims
Maybe for crank and cam bearing journals

Cheers

Hi Tony,

I am 'old school' to prefer micrometer's find you can a get a better 'feel' when measuring thicknes of shims and diameters of cranks ect but that was the way i was taught i guess. Just need to remind myself sometimes what micrometer i have in my hand, everthing at work is metric and at home is imperial.
Some measuring jobs a vernier is best

Cheers John

Like everything else it depends. Micrometers are only made in 1"(25mm) increments. 0-1", 1-2", 3-4" ect. ect.(Ok I know you can get a set that has a range of extensions and calibration standards that will go up to many inches or feet)

Calipers can be bought 0-4", 0-6", 0-8" ect. I have a 24" set at work.

Micrometers are always more accurate than calipers(guess sticks). An experienced person can accurately measure with a micrometer better than .0001". That is what you would want for crank or cam bearing journals.

Calipers will measure things that micrometers can't of course. Just because the resolution of the caliper is .0005" doesn't mean it is that accurate though. To measure with a pair of calipers one must be familiar with that set of calipers and have experience with calipers in general.

So as I said...it depends.

Calipers would be good enough for pallet shims.

I have a good quality set of calipers, with digital inch or metric read out, which I find quite good. They do not reach far enough to measure a big crank, & some other stuff.

I still use a micrometer for serious stuff, & find I get more accurate results with them.
