Adjustable Box Joint Jig

Precision is critical when making box joints — and this Adjustable Box Joint Jig is designed to deliver perfect results every time. Unlike typical jigs that attach to a miter gauge (and suffer from bar slop that reduces accuracy), this woodworking jig fits directly into the miter gauge slots of your table saw. With both sides of the jig acting as runners, you get smooth, stable travel without any risk of racking.

For even greater accuracy, this jig replaces traditional adjustable index keys with a smarter system: removable fences, each with its own fixed key sized for different box joints. No more time-consuming fine-tuning. A built-in stop ensures each fence locks back into the exact same position for repeatable, reliable cuts.

With these easy-to-follow woodworking plans, you can build your own DIY box joint jig and start making strong, perfectly spaced box joints for boxes, drawers, and furniture projects. Take your woodworking to the next level with our detailed Adjustable Box Joint Jig plans — and enjoy the satisfaction of perfectly aligned joints on every project.
