WHERE pencil lines must be laid out parallel to a surface the usual method of using a rule or a straightedge can be supplanted by the quick and accurate method afforded by a trysquare prepared in a manner shown in the sketch.

A series of holes 3/32" in diameter should be drilled through the blade of the square at every 1/4" mark. If finer calibration is desired these holes can be drilled at every 1/8" mark. The centering of the holes must be accurate. In order to do this, center punch marks must be made at each division mark where a hole is to be drilled. If a burr is left on the metal after the hole has been drilled, it can be removed by using a drill of larger diameter as a countersink.

In use, the handle of the trysquare is held firmly against the edge of the stock and is drawn toward the user while the point of a pencil is held in the required hole.
