Using an accurate micrometer (not a caliper) that is of the range needed. 2 to 3" or 3 to 4' probably, measure 9 places on each journal. Start at the front of the crank, and make a spread sheet, or paper copy of the measurements. On each journal (rod and main) measure three places at the front of the journal at 120 degree separation. Then go to the middle of the journal and again measure 120 degrees apart. Then at the crank edge of each journal. These nine measurements give you taper of the journal and eccentricity (egg shapeness) write each measurement even if it matches the one before it. Be very touch sensitive when adjusting the micrometer. Assure it is flat front to back, and measuring directly across the diameter. Be sure to apply only enough pressure to just barely let it be stable and flat to the work. Practice measuring on the same piece of material (Like an old wrist pin) for 15 trys to make sure you are consistent. More than .ooo8 out of round (egg shape) and .0005 taper wil need to be ground.
