Pocket hole joinery has been around a long time, but it was the Kreg Jig that made pocket holes quick and simple to do. Invented in the late 1980s by Craig Sommerfeld, the jig allows a woodworker of any skill level to build reliable, strong, and rapid square joints that hide the screws. From there, it’s an endless world of projects that you can knock out without having to wait for glue to dry. Build picture frames, cabinet boxes, shop jigs, face frames; assemble coffee tables, benches, bed parts, etc. You’ll find thousands of home projects built with the Kreg Jig on how-to websites like Ana White and Kreg’s owner community.
The jig itself is the blue thing, about 3″ wide and 10″ long. While it’s manufactured with a smart notch for clamping down to your workbench or table, sometimes you want to do better than that. The mount you see here is just a piece of 3/4″ thick Baltic birch plywood cut to 20″x16″, an arbitrary size. The key is to have a workable surface that can be clamped down and that can support a long workpiece like a cabinet side.
