ABSTRACT:
An improved measuring and gauging instrument is provided for determining concentricity, out of roundness, flatness, diameters, thickness, and the like dimensions, of a workpiece for checking or comparing the accuracy of the workpiece. The instrument includes a stand or frame having a bar upon which is mounted one or more V-blocks, or mounting blocks, with each V-block having a fixedly mounted indicator dial and each mounting block having a floatingly mounted gauge. The fixedly indicator dial is used to check a workpiece for concentricity, out of roundness and diameters. The floating gauge has an anvil for engaging an undersurface of a workpiece with the contact point of the gauge engaging the workpiece at the opposite side thereof whereupon the thickness and out of roundness of the workpiece is checked. The floating gauge may be used on bench-center gauges, indicator stands and the like.
