Made this jig to drill cribbage boards, but would work for anything needing evenly spaced holes
I used a box joint jig to create 1/4” dados 3/8” deep in 3” x 24” 4/4 poplar. I glued a “cap” on top to hopefully keep the fingers from breaking off and glued that to a scrap piece of plywood.
To align the jig I butt it against the Drill press fence and move in to give the line I want to drill. The jig is then moved back and forth along the fence to the desired starting point and then clamped down.
The stop block has 2 fingers on it that engage the dados and “lock” into place. For 1/2 inch spacing the block is moved one notch. For 1/4 inch spacing the stop is flipped for the next hole (the width of the stop is 3 inches and one side does not have a finger).
It works well, but as always I managed to get a couple of Wonky holes. A friend says not to worry, “consider it a signature of sorts”.
