A hole drilling jig

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”.

Fantastic idea. I have been pondering a new drill press table for some time. I will incorporate this idea into the design. Thanks for the idea and the great pics.

If you don’t mind I would like to incorporate this spacer system in a jig for my over head router table to space the grooves for a CD/DVD rack.
Have been trying to work out a system for spacing.. now I have it.. thanks for your fine idea.

This is great! I can see other applications forming in my mind as I look at it. I might even make one to make a cribbage board sometime. Thanks for the post.

I wonder about drill wander on this ? would you not be better with an engineers centre drill since these are not through holes (I suspect ) your drilling .So heck it might be worth a try. They make very even and accurately round holes .Alistair

I usually use bradpoint bits, and they do work better, but this particular board is very thin and I was afraid the bradpoint would penetrate all of the way through.
