Rudder
The rudder consists of a skeleton that is made up of the main spar and ribs on both ends. The skin of the rudder has small stiffeners attached to it to give it rigidity. The skin requires the trailing edge bend that was started at the factory be finished by the builder. The leading edge of the rudder must also be formed into a round shape.

May 6, 2001 - 4.5 hours
Trimmed and deburred the Rudder stiffiners. Started deburring the rest of the rudder parts.

May 9, 2001 - 0.75 hours
Finished deburring the rudder parts.

May 10, 2001 - 0.5 hours
Finished sanding the rest of the rudder parts.

There are a lot of parts in the rudder. This is fun!!!

May 11, 2001 - 0.5 hours
Ground off the what was left of the little guide hole on all the stiffeners. The more I looked at it the more it looked like a stress concentration in a fairly high stress place. See note.

May 12, 2001 - 2 hours
Etched, coated and primed all the rudder parts.

May 13, 2001 - 4 hours
Drilled all the rudder stiffeners to the rudder skin. Deburred and dimpled the stiffeners and skin and started back riveting the stiffeners to the skin.

Rudder stiffeners drilled and clecoed to the rudder skin.

Back rivet plate from Avery's that I set into a piece of 3/4" plywood.

May 14, 2001 - 1 hours
Riveted the stiffeners to the rudder

Rudder stiffeners riveted to the skin.

May 16, 2001 - 2.5 hours
Fabricated the little spacer that goes behind the rudder horn. Had to etch and prime it as well. Clamped the spar, reinforcement plates, lower rib and rudder horn together and drilled. Squeezed all the rivets that I could reach with the squeezer. I also built the homemade sheetmetal brake for forming the trailing edge of the control surfaces.

May 17, 2001 - 2 hours
Finished riveting the spar, rudder horn and lower rib together. Formed the trailing edge of the rudder and started setting up the V-block jigs.

Crunching (er. Forming) the trailing edge of the rudder. This works better than I thought it would.

May 28, 2001 - 4.5 hours
Finished drilling the rudder skeleton, set up the V-block jigs for the rudder, drilled and clecoed all of the rudder parts together in the jig.

Rudder in the V-block jigs all drilled and clecoed. Finally ready for some rivets.

May 29, 2001 - 3 hours
Deburred, dimpled and started riveting all of the rudder parts together.

June 1, 2001 - 2 hours
Finished riveting the rudder skin to the skelton. Formed the leading edge of the rudder. Rudder is finished, except for fiberglass and the counterweight.

Detail of the rudder leading edge and one of the rod end bearings that serve to attach the rudder to the vertical stabilizer.

Finished rudder attached to the vertical stabilizer. The funny looking coating is the contact paper that I put on to protect it.
