Build a Surfboard Episode 1: Shaping

Step 9 "Skin" the Bottom

After shaping the rocker there's still untouched blank in the middle of the board. The foam that was in contact with the mold has a yellowish skin of higher density urethane with traces of mold release on it. That needs to come off. To take that off without messing up the nice curve he put so much work into, Johnny planes 1/8" of the whole surface of the board. He rests the front of the planer on unplaned surface for the whole stroke. That reference surface makes the operation quick and easy. You can hear the sound get louder as the blade hits the higher density skin foam or the wooden stringer.

Speaking of loudness, Johnny wears a pair of "Peltor Worktunes" hearing protector headphones with a built-in radio while he works.
