Often on the shop floor you would like to verify the settings of the gage you are using.There are several simple methods to ensure your settings stay correct. Today’s tip covers the MRP® crest diameter and ovality gage and coupling inspection.

When using an MRP® crest diameter gage to inspect crest diameter on a coupling, mark the location of the MRP (the edge of the blocks and the position of the arm) of the 1st machined part, and record the gage reading.

Leave this 1st machined part nearby to verify between each additional machined coupling that the gage is still set properly. You can always use your rod standards to double check or reset the gage.
