Starrett 103-C Adjustment
« on: August 04, 2013, 12:40:19 AM »
I inherited A Starrett 103-C 0-1” micrometer from my late father. It came to me without a case, instructions, or calibration wrench. Does anyone out there have one of these mics that could provide the instructions as to the calibration? I have a gage block set coming in a few days, and will be able to check its accuracy, but would like to be able to adjust it if necessary.

Chuck, see if this helps. If not google micrometer calibrations and you will get other hits as well,

My mistake, the mic is a Starrett #203-C, not a #103-C.

The dia of the barrel is .476” and the pin hole is a snug fit for a #52 drill shank. The Starrett measures the drill shank at .0625”.
