Re: Micrometer



Whoops!~ Sorry for the previous post.

Having worked for Intel in the incoming inspection area for many years, I
know something about micrometers.  At issue would be what is being measured
that would require the accuracy of a micrometer?  Paper thickness? Metal
thickness. The difference can be considerable. When measuring something soft,
sometimes a special micrometer that registers the pressure being applied to
the sample is required.  This, of course, isn't required when measuring hard
samples such as metal.   There is also the type of micrometer where the shaft
(?) doesn't rotate (most do) and this might be another feature you would want
for very fine or soft papers.

However, the bottom line with micrometers, or anyother fine-measurement
instrument, is that proper training (there are books on the subject),
calibration and maintanence are all essential elements for the best quality
measurements.  Without all of these, even the best-made micrometer will
render nothing but useless information.

With all of that said: you really can't go wrong with Starrett quality. I've
tried them all and invariably have ended up with Starrett since they seem to
holdup the best under hard day-in-day-out use.   I would also suggest
contacting a local company that specializes in calibration and have them
inspect and test your instrument on a regular basis.
