Skateboarders will use just about anything to perform tricks on, but having a well-constructed piece of equipment always makes the sport more exciting. A grind box, also called a grind ledge or a fun box, is a relatively small box that can be transported easily. It is used to do a number of skateboarding street tricks, including grinds, ollies and board slides. The key to building a grind box is solid construction, otherwise the continued wear that comes from slamming into it with a skateboard can cause it to break and lead to accidents.

Things you need
- 4 pieces of 96-inch, 2-by-4 pressure-treated lumber
- 12 pieces of 21-inch, 2-by-4 pressure-treated lumber
- Wood glue
- 2-inch galvanised spiral nails
- Measuring tape
- 6 pieces of 12-inch, 2-by-4 pressure-treated lumber
- 3/4-inch plywood, 96-by-24 inches
- 3/4-inch plywood, 96-by-12 inches
Set two pieces of 96-inch 2-by-4 pressure-treated lumber parallel to each other with the wide sides facing one another. Place a 21-inch 2-by-4 between the two pieces at both ends and directly in the middle. Cover the ends of the short 2-by-4s with glue and attach them to the long 2-by-4s, then nail them in place to create a rectangular frame with a support in the centre.
Create a second rectangular frame in the exact same way the first was built. Add an additional 21-inch 2-by-4 every 12 inches, so there are seven in all. The finished rectangle should look much like a ladder.
Take the first rectangle and set one of the 12-inch 2-by-4s inside each of the four corners. Glue the 12-inch 2-by-4s to the corners and nail them in place. Nail from the inside of the rectangle out. Place the remaining two 12-inch boards against the middle brace, on opposite sides. Glue and nail them in place.
Set the ladder-like rectangle on top of the other rectangle so the top of the 12-inch boards are flush with the top of the rectangle. The boards should line up tight against the corners and the centre brace. Glue and nail the 12-inch boards to the ladder-like rectangle.
Glue and nail the large piece of plywood to the ladder-like side of the box. Place glue on all the edges and run a thin bead of glue down each of the centre supports. Nail down the plywood every 12 to 16 inches.
Attach the small piece of plywood to the side of the box. Place a liberal amount of glue down each of the long 2-by-4s and nail the plywood in place with a nail every 10 to 12 inches.
