Estes Saturn V Fin Fix, Part 2

Immediately after the wedge piece was glued on, I ran the edge down a rut in my corrugated cardboard cutting board.
This straight dip in the cardboard helped raise the sides of the glued piece up against the corners of the trailing edge.

After sanding down the overhanging plastic you can see a slight edge seam.
This will be easily filled with some primer filler.








Here's a fin before (on left)
and the reinforced trailing edge on the right.

The reinforced fins feel twice as strong as before!
