Spacers let you locate drilling positions
Having worked for more than forty years as a printer, WOOD. reader Bill Lacey is familiar with the process called step and repeat. In printing, images, for instance a business card, are reproduced in rows and columns to fill a full sheet of paper.
Because he builds toys in small batches and needs to quickly and accurately repeat drilling operations, Bill adapted this idea to his woodworking.
The jig has two components. The carriage, equipped with rear and end fences. And the spacers, which allow you to position your workpiece.
Build the carriage as shown in the drawing. The size of the carriage can vary according to the size of pieces you are drilling and the maximum reach of your drill press. You can cut spacers to standard widths ahead of time, or custom-make spacers for each different job. Bill took the first approach, cutting spacers in widths from 1/8" to 1" in 1/16" increments, and from 1" to 6" in 1" increments. Cut all the spacers of the same width at the same time to ensure uniformity.
The photographs demonstrate using the jig to drill holes in a cribbage board. We positioned the workpiece by inserting spacers between the fences and the piece to progressively move it away from the end fence and out from the rear fence. The green spacers move the piece in 1/8" increments; the yellow spacers in 1/2" increments.
