Guide for Drawing Parallel Lines
H
ERE IS A TOOLused by old-time patternmakers and draftsmen to
lay out parallel lines. Strangely enough, I don’t think this tool
was ever commercially available; the old craftsmen just made their
own. The tool is simply a flat, 1-in.- to 2-in.-dia. steel, aluminum, or
brass disc with^1 ⁄ 16 -in.-dia. holes drilled around the edge. The space
between each hole and the edge of the disc determines the distance
between the drawn line and the fence guiding the disc. I bored
my holes in from the edge at points that mark the decimal equivalents
of fractions commonly used in woodworking. The^1 ⁄ 16 -in.-dia. holes
are just large enough to accommodate a scribe point or sharp
pencil point.
