Basically the process starts by making a jig (to form the rocker shape) and then you use the jig to build the board.
2 x 4 lumber (for the jig)
Cheap 1/8" plywood/ particle board (for the jig)
1/8" sheets of fine woods (for the board) - I used 4 [2' x 4'] sheets of 1/8" birch and 1 [2' x 4'] sheets of 1/8" mahogany for the centre of my board.
Marine Epoxy (Comes in 2 chemical parts you mix together then apply) - I have a picture of my epoxy before we started using it
Paint (I used metallic car paint, got a sample from an auto body shop)
Grip Tape (available at most board shops, anywhere they sell skateboards, West 49 etc)..
Wakeboard Fins (I used Ronix fins)
Step 1: Cut Out Rocker
[*The rocker is the curvature of the board, there are lots of different types of rockers, each will give the board a different feel, and different pop off the wake]
Draw the rocker shape onto 2 [2 x 4]'s that are 4 feet long, then cut along the line.
I hammered a few nails into the 2 x 4's *away from the cut line* and cut them both with one pass on the bandsaw
KEEP BOTH HALVES OF THE 2 x 4 YOU CUT, YOU NEED BOTH
You will end up with 2 'negative' pieces and 2 'positive' pieces.
I decided to make my board mimic the rocker of the Liquid Force 2008 Faction because that is what I had ridden before. So for me, it was easy to trace the rocker straight from the board then cut it out. You can design any rocker shape you want
