Step 2: Measure and Cut Wood Pieces

Measure and cut the plywood or MDF base to the desired size for your box joint jig. Then, cut two 1×4 or 2×4 lumber pieces to the same length as the base to act as fences for the jig. Next, measure and cut two hardwood guide bars to the length of the fences.

For cutting, do note you might want a guide on blade thicknesses, and here, we’ve provided it!

Step 3: Drill Guide Holes

Drill two guide holes into each fence piece and four guide holes into each guide bar. Make sure the holes are centered and square to the wood pieces.

Step 4: Assemble And Make A Box Joint Jig For Table Saw

Apply wood glue to one side of each guide bar and attach them to the center of each fence piece. Use screws to secure them in place. Then, attach the fence pieces to the base, ensuring they are perpendicular to it. Clamp the pieces together and let the glue dry completely.

Step 5: Cut Box Joint Slots

Place your wood piece to be jointed onto the jig and adjust the fence to the desired position. Cut the box joint slots using the table saw with a dado blade. Repeat this process until all the slots have been cut.
