My main hobby is knifemaking. To that end I have a fair stack of offcuts of pretty looking wood that I plan to use for fins by sticking them back together in some odd arrangements.
Aside from that, I also have made my own micarta handles for some knives and wondered about that process for fins. For those who don't know, micarta is essentially cloth (cotton, canvas, linen, etc) that is layered up with resin to form a solid and tough material. It's much the same as G10, which I know is used for fins, and that also gets used for knifehandles but the cloth is fiberglass.
So I'm wondering if anyone sees any reason not to lay up my own panels of micarta using scrap cloth and polyester resin, as I've done before for knives, to then shape some fins out of. I would suspect that after cutting and shaping it would need more sealing (or a fiberglass layer) but not sure if there is any other reason not to play at it.
To give an idea of what I've done before, see here:
