How to Build a Storage Chest

Set the blade of your circular saw to 45 degrees. Clamp a 1x6 skirtboard piece with the long edge hanging off the work surface, and rip a bevel along its entire length. Repeat on the other three pieces for the base. Then use the circular saw (or a sliding compound miter saw if you have one) to miter-cut the ends of these four skirtboards, as shown, to fit around the chest.
Next, take the lid you made back in Step 5 and clamp it overhanging your work surface. Use the circular saw to bevel the edges of the front and sides sloping in toward the chest.
