If the 3 1/16" bore is .060 over I should have at least 3.1225". Think my Harbor Freight instruments may be sub-standard? Will get the hand cleaner as described.

UPDATE: apology to Harbor Freight, reading dial incorrectly

Its .060" over. Carry on.Get the hand cleaner and a flex hone and then you will be able to give sound advice as a de glazer by saying bin there done that."LOL"
