2x4 Drill Jig for 5mm Dowels

This is a simple and sturdy jig I made to align 5mm dowel holes on various furniture builds I do. It can be used on any board with a 1.5-inch width. I have a version with a center peg you need to predrill a small hole to set it in and then you get a perfectly stable position with no wiggle. There is also a version with no peg, and you would tape this one down. And each version has little tabs along the center line of the outer edges to help you match it to a specific measured point. I do recommend a drill press, but I have used it with a hand drill on the edges of long boards I simply can't get under a press. I recommend a wider hole in that case to allow for any wiggle in your drilling. Then to make things shore up on those wider holes I use JB Weld Clear Epoxy in each hole before inserting the dowels, then add clamps to ensure a straight alignment and lock everything down with a rock-solid join.
