Title: Starrett 103-C Adjustment
Post by: Chuck in E. TN on August 03, 2013, 07:35:15 PM

 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.

There is a book on Ebay about Starrett micrometers How to read, use, care for and adjust them. Check it out if nobody has the right usermanual for the 103

Thanks for the link, Sid. $6.50 is a decent price until you figure in $21.85 for shipping.
I think not...

Title: Was: Starrett 103-C Adjustment, Now Starrett # 203-C

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”
