Go karts, known as "soap box cars" in the USA, are simple racing carts made of wood and used for racing games. The simplest go kart is made of plywood, has no steering and can move only if pushed, dragged or released down a hill. The most complex car has steering, looks like a scaled-down model of an actual car and even has pedals that allow the driver to move the vehicle. With a few basic materials and some tools, you can make a simple wooden go kart in an afternoon.
Place a 90 cm by 1.2 m (3 by 4 foot) plywood board on the floor for the bottom of the cart.
Attach two 1.2 m by 60 cm (4 by 2 foot) boards to either side for the side panels and two 90 cm by 60 cm (3 by 2 foot) boards for the front and back of the car. Use a staple gun to attach each plywood board to the bottom of the cart. You should have a 1.2 m (4 foot) long, 90 cm (3 foot) wide, 60 cm (2 foot) deep plywood box.
Attach a 90 cm by 60 cm (3 by 2 foot) plywood board to the top of the box at one end, making sure it is flush with the side panels. You should have a box that is covered on one side and open on the other. The front of the car will be the covered end.
Flip the soap boxcar upside down and attach an axle rod to the front and back of the car. Use notched 15 cm by 90 cm (6 inch by 3 foot) plywood boards to hold the axle rods in place. The notches should be small enough to fit the axle rods tightly but big enough so that the rods can spin. Staple the notched boards to the bottom of the cart.
Attach the wheels to each end of the axle rods.
Smooth the entire outer surface of the cart with sandpaper, and decorate the cart with paint as desired.
