Step 5: Join the form edges

Set the base of the form on your work surface. Stand two of the sides upright to create one corner of the form, with the wider piece overlapping the narrower one. Use a -inch bit and a drill/driver to make three pilot holes through the face of the overlapping board and into the edge of the other one. Secure the joint with 2-inch drywall screws. Repeat the process for three more corners to form a box.
