Abstract:
A gage set for measuring a characteristic of a part, said gage set comprising:a. a centerline hub comprising: (i) a body having a generally flat top surface; (ii) a post protruding up vertically from the top surface; and (iii) a plurality of positioning elements adjustably attachable to the top surface around the post and between the post and an edge of the top surface, wherein said positioning elements can be positioned around the post and attached to the top surface to hold the part by either an outer surface of the part or by an inner surface of the part and such that a center of the part is substantially aligned with a center of the post; and b. a gage comprising: (i) a support apparatus configured to straddle the post; (ii) a first block adjustably positionable along said support apparatus and having attached thereto an indicator with a spring-biased probe for contacting the part; and (iii) a second block adjustably positionable along said support apparatus and having a second probe for contacting the part; whereby when the positioning elements are appropriately adjusted to hold the part, and the first and second blocks are appropriately positioned and the gage is placed over the part and straddling the post, the second probe contacts the part and the spring-biased probe is biased against the part, such that when the gage is rotated the probes track along the part with the indicator indicating any movement of the spring-biased probe caused by variations in the part.
