I have a question about building wooden cored fins. I used some 1/4" cedar off cuts from another project and cut out fins from it. I hand shaped the foils with a piece of 100 grit paper, while sitting on the beach waiting for the tide, over a two day period.
As soon as I started foiling them, I realized I had cut them out wrong. The grain of the wood runs horizontally across the fin, instead of vertically up the fin. I figured I would use them for practice foiling and continued on.
After finishing with them, I have grown kind of attached. I really want to glass them and put them on my next board.
Is the core where a fin gets it’s stregnth? Or the glass?
Is the wood inside just a good looking, light weight filler material?
They are pretty flexy. Actually really flexy. But they are tabbed for FCS plugs, should I just glass and try them?
