<DIV>What you require is a multi-anvil micrometer. I have been =
using one for
many years to measure the strings in the piano. It is particularly =
handy
when you are dealing with a broken bass string, since you can =
measure the
cover and core diameters of the adjacent strings in the piano =
without
letting the tension off.</DIV>

<DIV>The above image, of the Mitutoyo 117-101, 0-25 mm metric =
micrometer
(they also make an Imperial measurement version), was taken from =
the
Mitutoyo website at;</DIV>

<DIV><BR></DIV>
<DIV>These micrometers come with a round and flat anvil. The round =
anvil is
used for measuring tube wall thickness. They are more expensive =
than a
standard micrometer, but you'll have it for the rest of your =
working life.
My multi-anvil is a Starrett, but the Mutitoyo is better =
made.</DIV>
