Rudder Rib and Brace Assembly

 

The aluminum rudder frame has been acetone-cleaned, 80 grit sanded and re-cleaned in preparation for Aeropoxy attachment of ribs and braces. Clear shipping tape was used on the table to prevent sticking, though I've read that two coats of paste wax on the melamine surface will yield the same effect.

Dry fit prior to cleaning

The foam is easily sanded by wrapping sandpaper around a tube to create the groove needed to mate with the rudder torque tube and trailing edge tube.
