ABSTRACT:
A gage that measures the size and out of roundness of the inside and outside diameters of ring-shaped parts comprises a centerline hub body together with a free style swing gage. The centerline hub body has extensible jaws that can be adjusted to position the body within the central opening of the part. A vertically protruding cylindrical post is located at the center of the hub body and is adapted to interface with the free style swing gage. The free style swing gage comprises a pair of parallel cylindrical rods that are adapted to fit over the centerline post. On each end of parallel rods is disposed a block, each block having a probe that protrudes downward from the block and is operable to contact a surface of the part to be checked. A front block is associated with a dial indicator connected with the probe to indicate any deviations in size or diameter of the part to be checked. The free style swing gage, together with the centerline post of the centerline hub body, allows the gage to be positioned at the actual centerline of the part. The free style swing gage is easily rotatable throughout the full 360 degree circumference of the part to be checked by grasping and rotating a handle on the rear block.
