final set up: new removable wooden fin and i used the dremel to cut off the side fins, and then sanded the areas down, and hot-coated those areas
so i went from this set up: removal middle fin, and two glassed on side bites.
6th step: after hotcoating both side, putting in the pin up front, and drilling the hole down the back section, it's done! psyched! now i just have to hope it's strong and the two fiberglass sections dont separate from the wood. it fits almost a bit too snug into the fin box so i think it'll be good! if it breaks off, i hope it floats so i can get it back...
5th step: done with building up the missing sections, and then i put on a couple layers of cloth over the whole fin on each side, and then a couple wrapping up from the bottom to seal the bottom
4th step: here's me after building up the fiberglass cloth in the missing sections. it's a mess, but it got it done!
2nd step: foiled it down to give it the widest point at about 1/3 the length from the fin. the rest was eyeballed really. just try to make the plywood lines look good and reasonable basically. i wish i had more layers to play with and give it more of a dramatic look, but oh well. free wood is free wood. i cue off the bottom front and back because there will be a pin through it in the front and a hole in the back. these would be points that i'd have trouble sealing to be waterproof, so i figured i'd just build up fiberglass cloth, with lots of layers, in these areas and then just deal with that to put the pin through and hole and it'd still be waterproof. this toook a while- i have no idea how many layers of cloth it took to build it up.
1st step: rough cut of the outlinefinally! this took much longer than i thought, but it's all done. here's a few pics of it along the way:
