Sky Hook Build Part 2

I've always like the look of the Sky Hook fins.

There's subtle angles, a rounded trailing tip and a very small concave notch where the trailing edge meets the body tube.

The instructions tell you to round all edges except for the root edge.

That small notch at the bottom of the root edge would disapear or be broken off if I were to try and round it.

I used the angled edge of my wooden sanding block to get into the notch. I'll leave it square where it becomes the root edge.

In the picture the trailing edge is against the block. That little notch is against the angled wedge of the wooden Warner sanding block.
