Build a Surfboard Episode 1: Shaping

Step 8Shape the Rocker

Shape the Rocker
Johnny likes a lot of rocker. He says "Rocker lets you put your weigh forward on the board. It makes the board faster. You can't have enough rocker. Until you have too much. Too much makes the board slow."
Here's a masonite rocker template he made for a previous board. For the current board he shapes the rocker by eyeball.

There are fluorescent "sidelights" along each side of the room at elbow height. This light hits the board at a low angle and lets him see any bump or irregularity in the board.

That means planing a lot of material off the ends of the board to increase the rocker.
He checks the board for flatness and twist by raising and lowering on end while sighting down the bottom.
Another method is to put two levels across the board at two different points and sighting across them to see if they're canted.
