How to Build a Fun Box

Fun boxes, or grind boxes, come in myriad types and sizes and are among the easiest and least expensive skateboarding obstacles to build. Fun boxes make skateboarding fun in urban areas and add depth and dimension to the sport. Building a fun box can be a daunting task, especially for someone who lacks a strong background in construction or carpentry. But, with the right tools and materials, you can construct a fun box with relative ease.

      Construct the sides of the fun box. Cut the two 8-foot 2-by-4 boards into seven 8-inch pieces. Use the drill and wood screws to attach the 8-inch pieces as joists to two of the 10-foot 2-by-4 boards about 18 inches on center, creating a rectangular box for the first side. Repeat this step to construct the other side of the box.

      Turn the two side pieces into a box by framing them together. Cut the 2-by-6 board into 10-1/2-inch pieces. Use four of these pieces to attach the sides of the box at the inside corners of both ends. Now attach the middle of the sides using two 10-1/2-inch pieces.

      Surface the top and sides of the box using the sheet of plywood. Plywood, even when treated, isn't weatherproof. To make the ramp waterproof, add a layer of Skatelite over the plywood. Some people add even more protection to the plywood by placing a layer of tar paper under the Skatelite.

      Add the corner pieces to each side of the top of the box. Using a special drill bit for metal, punch four holes in the metal corner pieces and countersink them. Attach the corner pieces to both sides of the top of the box.
