[QUOTE="Mikecr, post: 636832, member: 1521"] I agree that runout is not the same as concentricity, and that too many tools are merchandised incorrectly. As to confusion; You state that any shape can be concentric(centered), I agree. Yet you contend that an outside 180deg comparison is required to measure it. Well, how would your indicators subtract to leave only eccentricity, if opposing sides are not the same distance from your center? I contend that w/resp to your method of measure, concentricty is qualified only with diametric stock (lathe turned, etc). [/QUOTE]
