Abstract
A measurement tool adapted for measuring surfaces of a known desired curvature and specifically grooves, holes, chips, gouges, chafing and/or out of round areas therein. The measurement device is constructed with an attachment member having a curvature matching the "set up" curvature of the part to be measured. The measuring member or probe, is sharpened to permit it to extend through an aperture formed in the attachment member for facilitating its initial setting relative to the attachment member and the surface to be measured. Any movement of the probe during measurement is then a manifestation of a deviation from the original "set up" curvature.
