When you get it set, don't read the post Mic, but read the OD, of the post Mic, with an outside Mic.
We build bearings every day, and can't afford to be wrong, even once.
They make smaller ones also, that we use, and also other designs, that are a 3 leg type, spendee, but so are mistakes.
Last point, There has never been an instant, for us, in 54 years, that any kind of cylinder bore mike, reading, has been accurate enough, to read bearing sizes, or oil clearance, and there has been countless instances.
Thanks,
