While working on a cabinet, I needed a quick way to square up the corners of some fairly large pieces. I found the answer in my scrap box.

Starting with a piece of 34 " hardwood about 3" wide and 6" long, I centered a 38 "-deep kerf down the length of the piece to snugly fit the legs of my small framing square. Then I crosscut the blank in half.

To use the supports, I simply fit the blocks on the square, where shown, and clamp them to the two pieces being assembled. This setup frees my hands, too.
