Made from 3/4" plywood

1 - 8" x 8"

2 - 4" x 4"


Step 1: Cut the Three Pieces

Out of 3/4" plywood but one pice 8" x 8" and two pieces 4" x 4" on your table saw or miter saw. I made four of these jigs at one time and batching them out was very simple.

Step 2: Assemble the Jig

Using wood glue and 2" finish nails stack the two 4" squares on top of one another and then attach them to the 8" square. They should be flush to one corner and avoid putting nails in the center of the small squares.

Step 3: Drill Hole for Clamps

Using a 2 1/8" forstner bit drill a hole in the center of the 4" square. The whole should be approximately 1 3/4" deep.

Step 4: Cut a Channel for Glue Squeeze Out

Mark and cut out a 3/4" wide channel from the inside corner of the 4" square. This channel does not have to be precise in width or placement and is used to clean off glue squeeze out when assembling miters on the jig.

Step 5: Use the Jig and Assemble Some Miters!

Now you can use the jig to clamp miter joints in place during glue up. Sometimes it takes a little adjustment to get the correct pressure on the joint but this jig works really well! As always thanks for following along!
