Pic Controllers

So this was our first project ever, and it came out impressively nice. I had an old early 80's WRV surfboard passed down to me by my Dad. Its an awesome board, but I came to find out they no longer made fins for it (G & S star system fins).

This is the original fin I used as a master copy... It is no longer made and I had to go to 13 different surf shops to even find this one... but only one. It was in a scrap fin box, but they still charged me $25... so I decided to try and fabricate my own fins.

This is the board, quite a nice looking board if I do say so myself... and i do.

This is the MDF fin we cut out and sanded. At this point we still had no idea how they would secure to the board.

The fin was then fiberglassed and sanded back down to shape.

And then they were painted, We are all quite big checker fans, and the blue blends so nicely with the board.

.... ya.

And now on the board.

So this was a failed attempt to later make fins out of plexiglas, not a good idea, they looked sweet and fit perfectly, but snapped on day 2.

First day of testin' them out, quite nice. They ended up lasting over a year, and only because the fiberglas eventually rubbed down and the MDF split, this has been since remedied by putting a little bit of fiberglas resin on the tips every now and then. I've also made a set of batwing fins that I currently have on, I'll post pics of them at some point.

beach fun.

Edit: (June 26, 2008) So apparently the locks I made for the batwing fins didn't hold up well enough, because I lost one at sea last time. I made another set similar to the original checkered ones, though these I didn't paint. They actually look kinda cool, you can see the weave of the fiberglas cloth a little, and they have a greenish tint. Quite sturdy as well I must say. These ones better stay in. I've streamlined the building process, but they still take about a day to go from blank mdf to fins secured in the board.

Edit: (August 21, 2008) The fins I made started bending because there was a small hole in the fiberglass that allowed water to get into the mdf and swell. I dried them out and sealed them up, but still wasn't too confident with the mdf… My new plan of action was to find a way to make the fins entirely water proof, thus removing the mdf core. A solid fiberglass fin makes sense, seeing as that’s how most of them are actually made, but the fiberglass I can get a hold of is not as strong as the what real fins are made of… A compromise was reached. First I vacuum formed the first set of fins (the checkered ones), creating a lexane mold. The good thing about this is that each sheet of lexane is about $2.50, so they're pretty much disposable if they don't make it through the entire mold process (One ended up surving, and one cracked in the mold release stage, but the good one was so gunked that I trashed it anyways). So with the molds I used petroleum jelly as a mold release, coating the insides of both of them. I then layered the molds with resin and cloth. I used 2 sheets of cloth per fin, so I layered them with resin-cloth-resin-cloth-resin… then placed a sheet of wax paper over top to get a clean surface. The entire process suprisingly worked quite well. The mold release worked pretty decent, though I wasn't to worried about breaking the lexane to get the fin out. Once I pulled out the fin I scrolled off the edges that needed to be straight, with vacuum forming its quite tough to get 90 degee edges, but no biggy, just needed a little cleaning up. I then tested them for strength, they seemed to bend a little easier than I liked, but seemed quite tough, so my solution was to cut them down. Now that I think about it I could probably make the lexane fins again, but make them a little shorter as well, its worth a shot. Either way, I've successfully made a fully water proof set of fins that look sweet and have survived a 3 day surfing camping trip with no complications. If these ones last a year without any problems like the first set I'll be happy. I'll give the lexane fins another shot eventually. Oh, and on a side note, I saw an old twin fin Challenger surfboard at COS surf in Jax beach with two perfect clear G & S Star system fins… but the owner had it as a collector board, not for sale! I just about flipped out, the only complete set I have ever seen with my own eyes, and they were unattainable. He said the only valuable thing about the board were the fin box/ fins… ya, tell me about it.

Well I'll put up pictures soon of the whole process, and the final fins on the board. As well as posting the SNES controller pictures soon.
