ABSTRACT:
The invention provides a gage for measuring the center height of a cylindrical workpiece. The gage includes an elongate body having an arcuate face portion with a plurality of numbers in sequence thereon indicating a value of the diameter of the workpiece. The face portion also includes a plurality of substantially vertical lines, each line corresponding to each one of the sequential numbers and a horizontal centerline. A plurality of horizontal indicator lines extend above and below the centerline, each line indicating a value corresponding to a distance above or below the center height of the workpiece. An indicator consisting of an indicator arm positioned along the centerline and a pair of feeler arms is pivotably mounted on the body. The gage is slidably inserted in the recess of a cut-off tool holder and moved alongside a workpiece. The indicator arm will then move upwardly or downwardly. The intersection point of the upper horizontal surface of the indicator arm with the vertical line following each number corresponding to the workpiece diameter will indicate the distance the cut-off tool is below or above the centerline of the workpiece.
