Frozen micrometer

[JScott]

Tom, good tip and I have contemplated doing a heating and cooling expansion/contraction cycle with a hair dryer and upside down canned air. I was hoping it was just congealed lube in the threads but this thing is locked down tighter than Dick's hat band. I mean it doesn't wiggle or budge. I tried turning the barrel using the little adjustment spanner and felt no give in either direction. I have done a little reading and research and apparently the thimble can be pulled off the barrel. It might require some tapping though. The program now is Kroil until the weekend and then the wrestling begins!
