Glen,
Like you I'm buying some measurement equipment needed for blueprinting
the first of my V8 engines.
Given the choice between a 0-1" micrometer and a 0-6" dial caliper I
would always choose for the dial caliper.
Of course the question is what do you intend to measure on a regular
basis.
For engine building one needs larger micrometers for crank journals and
pistons and the like.
As for accuracy. Proper measuring is an art in itself. They nearly all
reed to 0.01 mm but with analog
readings you can measure thousands of a mm between the stripes.
Now I have a question also.
In the various (american) magazines and books I have on the subject of
blueprinting
engines there is always mention of snapgauges for measuring internal
diameters.
After measuring the internal diameter the snapgauge is locked and then
the snapgauge is measured in a micrometer.
These snapgauges are much, much cheeper then a dialcalipergauge for
internal diameters.
Can any of you give me a brand name or web site or prices for these
snapgauges?
Lex.

Onderwerp: Micrometer vs Dial Caliper Tool Question
I'm looking at spending some of my limited tool budget on some
measurement
equipment.
I just bought a dial indicator and stand for checking runouts, but now
I've
got a bit of a dilemma.
I am probably in a position where, for the time being, I will have to
choose
between buying a
0-6" DIAL CALIPER and and a 0-1" MICROMETER.
The dial caliper seems to be a much more flexible instrument in many
ways,
although I suppose the micrometer would be better for an absolute
measurement of something very thin, like a shim.
So the question is, how much can I really do with the dial caliper vs.
the
micrometer in general automotive work?
I'd appreciate any comments.
