Cut and Assemble
Cut the top or face of the scoreboard. Use the 1/2-inch thick plywood and make a rectangle 24 by 48 inches.
Cut the cornhole. The cornhole is a 6-inch diameter hole that is centered 9 inches from the top of the board and 12 inches from either side. Use a hole router or jigsaw to cut this hole. Use a file or sandpaper to smooth the edges of the hole.
Cut the back. Use 1/2-inch thick plywood and cut a piece 24 by 11 1/2 inches. Attach this to the bottom of the scoreboard at the end with the cornhole. Attach with glue, screws or nails at a 90-degree angle.
Optional: For a portable scoreboard, use a hinge to attach the back. Make it so when the hinge is fully open, the back is at the 90-degree angle required for play, and when it is closed the back folds neatly under the face of the scoreboard.
Cut the front. The front of the scoreboard should be cut from 1/2-inch plywood, 2 by 24 inches. Attach this at a 90-degree angle to the other end on the bottom of the face of the scoreboard using glue, screws or nails. You can hinge this similar to the back (explained in Step 3) to make the board lie flatter for transportation.
Cut the sides. Place the 16-by-47-inch board flush with the edges of the top, back and sides. Mark a line from the bottom of the back to the bottom of the front using a long ruler or a straight piece of wood. Cut along this line. Repeat with the other side. Attach the sides with glue, screws or nails. Sides are optional and usually not included on portable scoreboards.
Finish the scoreboard. Smooth the edges. Use a file or sandpaper to smooth the edges that have been cut and joined. Paint the scoreboard with a high-gloss latex paint, preferably white.
