Ocean-themed decor brings the beach into any home or office. Recycle that treasured surfboard that you started with by transforming it into a bench. A retired board may also be found in a secondhand shop when scouting out unusual finds for making furniture. Surfboards vary from a 5-foott, 8-inch to 7-foot shortboard to longboards that range from 9 feet to a 12-foot, 1-inch length. The flat middle section needs to support the seating area of the bench. Choose 16- to 20-inch-high posts for the desired height of the bench when shopping at the lumber yard.
Measure the length and width of the surfboard from end to end and side to side to locate the center point. Make an X with a marker on the center point.
Turn the board upside down on a flat surface. Place a level vertically across the center point to ensure the area is level.
Measure and mark a 14- to 16-inch-wide by 3- to 6-foot-long rectangle on the bottom of the board. Measure away from the curvature of the rails or edges of the board to the flatter, level bottom surface. The rectangle should only cover the level surface of the board.
Cut four 1-by-4 boards to the length of the rectangular shape. Cut four more 1-by-4 boards to the 14- to 16-inch length of the width of the rectangle.
Attach one of the longest boards to the top of the sides of two of the 4-by-4 support or leg posts using 2-inch deck screws. Attach another of the longest boards to the other pair of legs to make the two sides of the support system.
Attach one of the shortest boards to the top sides of two of the posts with screws. Secure the sections together with clamps to hold the sides in place. Attach a second set of the long and short boards 5 inches down from the bottom sides of the first set of boards. This provides further support to the open box shape of the system.
Tear off four strips of painter's tape and apply it to the surface of the board where the pilot holes will be located. Mark the point on the tape where the screws will insert into the board.
Hold the drill bit against the painter's tape. Drill slowly through the wood or resin-coated fiberglass covered top of the board and down into the polystyrene or polyethylene foam interior. Keep the pressure consistent and slow to prevent cracking the board. Remove the tape.
Center the board over the posts or legs of the support system. The holes should line up with the center of the top of each post. Insert a screw into the first hole. Use the drill to securely sink it into the board and into the wooden leg.
Cut two to four 1-by-4 boards. Secure them in place under the flat section of the surfboard by attaching them to the horizontal side boards of the support system with wood screws.
Apply a coat of resin to the four holes in the top of the surfboard to cover the tops of the screws for a more finished look. Follow your resin product directions.
