Build a Surfboard Episode 1: Shaping

Step 11Block Sand the Outline

Block Sand the Outline
Use a block of wood with a piece of 50 grit sandpaper wrapped around it to sand the edges of your blank smooth. There are some scratches in the blank from sawing it.
To sand them out Johnny says "Sand everything AROUND the scratches. The scratches make that foam low-density, and it comes off real easy, so if you sand there, you'll get a big divot. Put the pressure everywhere else. The foam with no scratches is solid. You need to lower it to the same height as the scratch, to get the whole thing to come down together."
Check the width of the board at the foot marks and the middle to make sure it's symmetrical.

So far the deck of the board hasn't been touched. You can see the yellowish skin on the front half of the board. Sunlight makes it turn yellow and then brown. In the background there's an old Clark blank that's turned brown.
