Instructions
Set two 48-inch boards on edge, parallel so the outside surfaces of the boards are 20 inches apart. Position a 32-inch board against each pair of ends on the 48-inch boards. The ends of the 32-inch boards are 6 inches away from the sides of the 48-inch boards. Screw six screws through each 32-inch board so three screws enter each end of the 48-inch boards. This is the frame to your Waverunner roller.
Turn the frame to your roller over so the 32-inch boards are off of the ground. Screw two swivel wheels to each 32-inch board, one at each end of the boards so they're flush with the ends. Turn the roller over again so it's resting on the wheels.
Fold a carpet piece over the top edge of each 48-inch board so the ends of the carpet are flush with the ends of the boards. The 48-inch edges of the carpet will touch the top edges of the 32-inch boards. Staple the carpet pieces to the 48-inch boards using a staple for every 3 inches of coverage on each side of the boards. The carpet will keep the bottom of your Waverunner from being scratched.
