Quest Aerospace One Part 8 Step 18 - 19 Dowels

Jumping ahead:
I glued the dowels onto the wing and rudder pieces.

The instructions simply say to glued the dowel to the top edge.
I glued it on so the back end overhangs a slight amount. (Top rudder)
This way I could sand the dowel end to fit the trailing edge of the rudder.
(Lower rudder)

The joint was filled with thinned CWF. (Top rudder)
The CWF was sanded with sandpaper wrapped around a dowel. (Lower rudder)

Note: The dowels on the rudders sit forward on the outside edge.
The dowels on the wing are reversed, the ends hang over the trailing edge.
