Cleaning of the anvil was done at this time. While the oil was soaking through, light rotation of the spindle helps, like with any stuck screw. If a measuring tool can not reproducibly measure features to the appropriate precision, it needs repair or should be disposed of, as incorrect measurements may be more trouble than no measurement at all. Once the parts are clean and rust free, light machine oil, like watch oil, sewing machine oil, or, believe it or not, micrometer oil, should be used to wipe the inside of the thimble and the out side of the spindle cylinder. Even if it doesn't move, the force can help open up microscopic gaps that let capillary action do it thing.

Like other micrometers with the rotating sleeve, there should be a fair bit of friction from a flat spring between it and the barrel, and the sleeve may be move axially when it is rotated if axial force is applied. Question Cheap tools don't have the repeatability or precision to do good work, and are often unpleasant to use. It needs to be able to be moved without being so tight the wrench pin will break.

A well cared for micrometer can go decades without needing an adjustment, but due to slight mishandling, otherwise insignificant wear, and fumble-thumbed efforts to '"fix" a micrometer that just needs to be cleaned, many used units need to be zeroed. A minimum amount of light machine oil is appropriate. Be careful. You now have a functional, properly adjusted micrometer, ready for calibration and use. Had it been dropped?

With roots fixed firmly in Sheffield, England, the company began by manufacturing a range of calipers, screwdrivers, punches and other engineers tools. Using a set of gauge blocks, sized over the range of the micrometer and with size differences that bring the spindle to different rotations, I checked for parallelism of the faces and appropriate thread lead. You do not want to disturb the setting. Just no looseness or slop. It is a scrape and wipe job. This is a precision grind and polished smooth, not right off a bench grinder.
