OK, anybody who's bored with fin construction details blame Keef, I'm doing this at his request.

Basil has sliced me up some more end grain palm, and it's seasoned a bit more since the first one I made, so is a bit lighter.
First thing to do is mark out fin profile.
Palm marked out with Gav's shaped stainless leading edge alongside




Then because the palm has very little cross grain strength, I laminate a layer of 4oz glass onto one face to hold it together while I cut it out and foil the other side.





Once the epoxy's set I can start shaping the first side, possibly get around to that tomorrow.
