Get started by cutting the parts

The first step is cutting the plywood parts to the right size. Follow the Cutting List at right and the Cutting Diagram on p. 75. You can get great results with nothing more than a circular saw and a straightedge guide. With a guide like this, you just make two marks on the plywood for the size of the part you’re cutting. Then line up the guide with the marks and clamp it The only trick is to make sure the guide is on the side you want to keep. Then run the saw along the guide’s fence to make the cut.
