Things You'll Need
Instructions
Purchase the wood needed for the project. You will need one 1/2-inch by 2-foot board for the running board, handlebar uprights, a 2-inch by 3-inch board for the neck and a 3/4-inch think plywood board for the platform of the scooter. Pine works well for this purpose, but consider how you would like to finish the scooter to purchase the right kind of wood.
Put the handlebar and steering uprights together. Cut the 1/2-inch by 2-inch board so you have a 12-inch long piece for the handlebars and a 32-inch long piece for the steering uprights. Bolt two angle irons on either side of the steering upright tops and bolt the handlebar securely on the angle irons.
Drill a hole about 1 3/16-inches from the bottom of the steering wheel upright. The hole should be large enough to fit a 1/2-inch hexagonal bolt. Put the bolt through the wheels and the hole in the steering wheel upright. The wheels should be on either side of the steering wheel upright.
Place the washers on either side of each wheel. Secure the ends of the bolt with two nuts. The nuts will lock against each other to prevent any loosening from vibrations caused by the scooter in use. Screw two eye bolts on the inside of the steering wheel upright, with the first eye bolt about five-inches from the bottom and the second eye bolt about 5 1/4-inch above the first eye bolt.
Make the running board. Cut the 1 1/2-inch by 2-inch board down to 1 1/4-inch by 1 1/2-inch. Drill three holes in the top of the running board, with the first hole 6-inches from the left side, the second hole 16-inches from the left side and the third hole 22-inches from the left side. Drill three holes along the side of the board. These holes should be should be about two inches from each other and start half an inch from the top of the board. Repeat on the other side of the board.
Create the neck platform by cutting 1 1/2-inches by 2 1/2-inches from the board. Drill two holes into the side of the neck that are about one inch from the bottom and 1/2 inch from either side. Bolt the runner board to the neck and add two eye bolts to the side of the neck.
Create the platform of the scooter by cutting the 3/4-inch plywood into 22 1/2-inch by 5 3/4-inch pieces. Drill three pairs of holes into the platform. From the left to the right, the holes should be three inches apart and 1 1/4-inch from the edge. Bolt the platform to the running board with carriage bolts.
Bolt the neck to the steering uprights by lining up the eye bolts and threading a carriage bolt through the eye bolts. Tighten two nuts on the end of the bolts and consider increasing the neck strength with angle irons.
Insert carriage bolts through the eye bolts to add back wheels to the scooter. These carriage bolts should be inserted into the back of the running boards and the back boards. Screw a washer on both sides of the wheels and add two nuts to the end of the bolt
Build the brake with the T-hinges. Screw the hinge to the back of the platform so the long piece of the hinge drapes over the back wheel to stop or slow the scooter.
