Around two years ago, I found a really sweet piece of walnut. It was someones off-cut, clear as day, being weirdly thin and not quite rectilinear. The lighter edge will tell you that this piece has a splash of outer layer wood contrasting the dark heartwood grain. I was able to sketch a fin on this gold piece of scrap, create a diagonal cut, and insert my own walnut and oak endgrain checker pattern. The 21 1/2 squares are blocked by thin maple stringers, clamped between the walnut. Great project, but only time will tell if this fin ever sees time in the ocean. For now its a cool show piece.
