Surface Marking Block

A surface marking block is used to scribe layout lines at a chosen distance parallel to a reference surface. Typically this tool is used with a measuring tool to transfer the dimension to or from a work piece. The spindle can be adjusted at any position relative to the base (typically a surface plate) and is tightened with a spindle nut. A fine feed screw is used for finer adjustments. The tool comes with a straight scribe and a curved end scribe. Between the two shapes, a wide array of angles can be achieved for marking work and the curved end makes marking near or even below the surface plate an easy task. Retractable pins may be extended and used to aid in moving the gage horizontally along the edge of the surface plate for scribing a horizontal line. The scribe can be removed and a test indicator mounted in the larger holes for checking parallelism.
