FAQ Project Notes Project Summary Guestbook Other Stuff | 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. Trimmed and deburred the Rudder stiffiners. Started deburring the rest of the rudder parts. Finished deburring the rudder parts. Finished sanding the rest of the rudder parts.
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. Etched, coated and primed all the rudder parts. 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.
Riveted the stiffeners to the rudder
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. 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.
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.
Deburred, dimpled and started riveting all of the rudder parts together. Finished riveting the rudder skin to the skelton. Formed the leading edge of the rudder. Rudder is finished, except for fiberglass and the counterweight.
