I decided I wanted to make a surf board. I was bored and thought it would be a fun thing to make.
I started with a glued up walnut slab that I already had (My company makes wood countertops)
Since I have virtually no knowledge of surfboard design I winged it and drew it up in CAD after a little research.
I then threw it on the CNC and got to cutting. All this could be relatively easily shaped by hand as there aren't a lot of curves, would just be a little more time consuming.
Made a rough cut and then switched to ball nose and made a final pass. Walnut sands pretty easily so I didn't bother going super fine on the cut as the cut marks sand out easily. For a harder or more close grained wood you can step down the stepover on the bit and get an almost smooth surface, it just takes a lot longer.
From there it's a bunch of sanding. A bunch of sanding .
A little epoxy to fill any cracks and imperfections:
I then epoxied the whole things with a light layer to help with sealing. As a first go I didn't want to go to the trouble to glass it.
From there I CNC'ed out for a center fin (board is too shallow for the side fins using these Futures fin boxes)
Then sprayed with a Urethane clear and tossed on some grip:
First test was fairly successful, it's a little slow but very stable and easy to ride!
