I have a longboard in the works.....first one I've made since 1995. This time I decided to make my own glass on fin. Layed up a panel this morning. 34 layers thick. Shaped it this afternoon. Came out absolutely perfect. Very fun little project. I may be making shortboard fins in the future. I can see how this could become addicting.
By the way, any spots in the pictures are not in the fin. I doused the fin in water and took pictures quickly to capture the effect of what it will look like glossed on a board.
