ABSTRACT:
A gage and method are disclosed for measuring the inside or outside diameter of a product at a selected distance from the end of the product. The gage has a pair of blocks slidable along a pair of parallel vertical guide rails. Each block has a bearing pad which can be positioned against the end of the product to be measured. An arm extends horizontally from each block and is slidably mounted in an aperture extending through the block. A contact depends vertically from the end of each arm. One contact is mounted on a vertically reciprocable dial indicator plunger. The contacts are first positioned horizontally and vertically using gage blocks which correspond to the specified diameter and distance from the end of the pipe. The gage is then positioned against the end of the product and the contacts are brought into contact with the surface of the product at diametrically opposed points thereon. The dial indicator displays the deviation of the actual diameter from the specified diameter. This gage and method are particularly adapted to measuring pitch diameters of internally or externally, tapered or straight, threaded products.
