Estes Little Joe 1, #7255, Build Part 3, Fin Assembly

Here's the fin assembly from the bottom.
I wish the tabs were a little longer so they would stick above and could be sanded to surface. On these built up fins there is always something to fill with more CWF.

The leading edge is sanded to a taper to match the root and outside edge pieces.
The lowest line of the taper goes into the top of the "O" cut outs.

Here's the before and after:
On the left, the root and outside edge pieces are sanded to match the bottom pieces.

On the right, the top fin is before sanding the leading edge wedge.
Below is the sanded leading edge taper.

If you don't have one - GET A GOOD SANDING BLOCK! You'll never be able to get a sharp taper with sandpaper wrapped around your fingers.
