Fix a Very Broken Surf Board

Step 18: Feather it in

These little abrasive disks from the autobody supply store are great. They screw into a little rubber backing pad on a die grinder. Sand the edge of the new glass until it's so smooth it won't cut your arteries.

Flip the board over and use the orbital sander to smooth anything that grossly sticks up from the rest of the new glass. Don't cut the fibers of the cloth under the 4 oz. Don't even cut that if you're really an artisan.
