Semroc Wac Corporal Build, Part 5, Fin Shaping C

After doing the taper from the root edge - 

Start the leading and trailing edge tapers.

I've again marked the first high point with pencil.

Round off the sides to an rounded taper. The center area is the high point.

On the left is the root edge view, 

on the right is the leading and outside edge view.

The black ink remains for now. 

Each fin took 35 minutes to shape up to this point.

Here's all three, the shaping done.

The fin on the left has had the remaining ink sanded down with 400 grit.  

The edges are lightly rounded with 400 grit. Keep the root edge square.
