Yesterday I decided to purchase a blank center fin for the purpose of sanding it down and creating a center keel fin for my new fish. While at the surfshop I decided to go for "Plan B" and shape my own.
I used wood from our fence, planed it down using my neighbor Chad's planer, cut out the template with a jigsaw, sanded it, glassed it with three layers of cloth, sand it again, and sprayed it with laquor for a nice finish.
It took a day to create and I'll try it tomorrow. Lots of work but a lot of fun!
