Micrometer or digital caliper? A digital caliper is good for what it's intended for, but you can't get a precise enough measurement on a crank with one. They're usually only good to half a thousandth ( 0.0005"). You need something that will measure to one ten thousandth (0.0001")

These are what you need (if you buy from HF):

The listing says it goes to one thousandth, but the pictures shows one ten thousandths graduation (what mine is, the same set).
