Dec 16, 2022     Ongoing work on Rudder and Vertical Stabilizer - (8 hours)       Category: Empennage
Working on Rudder. I have finished the internal ribs and had to manufacture the upper support for the counterweight and the lower bracing for the rudder horn. The part I had purchased was for an older version that housed the counterweight internally in the tail cone. Pretty, but it interfered with the rudder, trim, and the pulleys that will control the tailwheel. The new version places the counterweight on topof the rudder, extending out over the vertical stabilizer. To put this all in place and ensure the parts don't interfere, it's necessary to fabricate and fit the vertical stabilzer. This is a 2 part piece of sheet metal. The forward piece was previously bent and required fitting and cutting to it's final form. Once cut, it is held in place with clamps. 3 internal ribs are attached to the forward Vert spar and provide structure to the forward part of the stabilizer. The middle part is supported by ribs and the forward and rear stabilizer spar. The rudder attaches to the rear spar and is positioned to ensure the upper counterweight is level and has plenty of clearance. Lots of fitting and cutting. Thanks to Evan for helping me draw the rough lines to get the 4 angles and bend of the forward piece set up.
