Hello all, Could some one please explain to me why you get different readings on a bore gage ( .0001 resolution) set with a set ring verses gage block or a micrometer.My brain ( or lack of it )just cannot uderstand why there is a difference.Given the set ring is round, but still a tangency point is a tangency point, only one point of contact.Has anyone ran across this before? Or was it me setting the bore gage. This was quite a while ago , so I don't remember the exact difference. Any input would be greatly appreciated. Thanks and have a great one, Hal
