The sport of Parkour was first introduced in San Francisco in 2005. Parkour involves movement of the body, including running, vaulting, flipping, balancing and climbing. David Belle, free runner, states, "Parkour is an art that helps you pass any obstacle to go from point A to point B using only the abilities of the human body." Many obstacles are used as platforms to move from one place or height to another. The vault box is one of these obstacles. Brian "Nosole" Orosco designed the vault box and uses it in his own Parkour activities.
Create the end trapezoids. To do this, use two 24-inch boards as the top and bottom horizontal supports. Two 28-inch boards serve as the vertical supports at 90 degrees. After attaching the vertical boards to the horizontal boards, you will have an excess of the vertical boards, which will be located inside the box. These notches are for the 56-inch boards to rest in.
Attach four of the 36-inch boards on each side. You will do this twice; two boards for each side of the vault box.
Connect the end trapezoids. Use all four 56-inch boards as support pieces and connect them lengthwise between the two end trapezoids. These boards will fit in the notches of the 28-inch boards that had slack from Step 1.
Insert the last two 28-inch boards in the center of the lengthwise support pieces, going in the same direction as the previous four 28-inch boards from the end trapezoids. Align the two 20-inch boards with the middle 28-inch boards and make sure they are horizontal, just as the 24-inch boards from the end trapezoids.
Create the box facing supports. Measure the positioning of the last two 36-inch boards. You will add them to the outside of the box. These should be located 26 inches from the ends. Once you have located the position of the boards, connect them on each side of the box.
Add the 26-inch and 28-inch boards, which will support the plywood facing outwards. Connect them between the triangular bottom, tilted slightly to follow the angle of the trapezoid. The inside bottom edge should be flush to the ground.
Create the box facing. Finish the sides and ends to close of the box with 3/4-inch plywood. The ends are optional, but highly recommended for added stability. Add the ends and the sides before finishing the top. Trim the plywood so that it is flush with the ground and flush with the top of the box. Use 1-inch plywood for the top. Trim as necessary so that it is flush to all the sides of the vault box.
Saw holes into the side of the vault box to use as handles for easy mobility. Paint the top of the vault box or cover with different textured materials for ease of vaulting and to prevent wear and splinters from occurring in the wood.
Serious injury can occur by not following directions and not using safety equipment. Always use safety gear, including gloves, helmet, and goggles to prevent injury.
