| 摘要 |
This invention relates to a gauge device which may be used by a toolmaker or machinist to determine the squareness of surfaces on a workpiece. The device has a handle having a gauge mounted adjacent an end of the arm opposite the handle and an intermediate contact point such that the inner surface of the handle and the intermediate contact point define the planes of the surfaces of the workpiece to be measured. The device is easily used, easily transported, and capable of use with work-pieces having chamfered or otherwise altered corners, holes, slots or other imperfections that make determination of squareness difficult.
