Step 2: Cutting the platform.
The shelves will become the platform of the segway. First, take one of the shelves and cut it in half. After it is cut in half, cut a rectangle out of the cut side, about 6 inches deep. Leave the side walls of the shelf. You should end up with a sort of U-shaped piece.
