This invention relates to a tool to be used in connection with doweling jig(s) of my U.S. Pat. application Ser. No. 850,582 filed Nov. 11, 1977 now U.S. Pat. No. 4,145,160, to expand their utility. This tool provides support to hold the jig above and parallel to a flat surface such as a piece of lumber, plywood, particle board or the like for direct drilling of precisely positioned perpendicular dowel pin holes to mate with identically positioned holes drilled or to be drilled in an edge or end of another workpiece; said pieces forming a right angle when joined together with dowels. Another application of this tool, unrelated to doweling, is for drilling equally spaced aligned holes in a flat surface.
