Shop-made guides make easy work of spacing holes
A recent project required drilling a large number of holes 3⁄8 " from the edge of a workpiece. It wasn't possible to use a drill press and fence to drill the holes, so I pondered a quick and accurate way to mark a line that distance from the edge for locating hand-drilled holes. Then I built the guide shown from scraps of 3⁄8 "-thick wood and 1⁄4 " hardboard. It worked so well, I made a set for other common dimensions.
