This hole-spacing jig RULES
Like many others, I used to use pegboard to drill spaced holes in cabinet sides for shelf pins. But I never liked how the drill bit would wallow out the pegboard holes, so I made my own drilling jig from a durable aluminum rule. Using a fence at the drill press, make the jig by drilling a straight line of 1⁄4 " holes at every inch mark on the rule.
To drill shelf-pin holes, simply tape the rule to the workpiece and have at it. The rule still works as well as ever at its usual tasks.
