Work continues on preparing the internal stiffeners, doublers, ribs, and other parts for the rudder. Many of these parts come joined to each other as a result of the manufacturing process, and I need to use the bandsaw to separate them and then grind down the rough edges. A few of the curved ribs needed fluting to allow them to rest flat. Additionally, some of the corners of ribs and the rudder horn needed to be ground down to make them less sharp.
Once the parts were all separated and smoothed, I started assembling a few of the pieces together with clecos to allow their shared holes to be match-drilled, though it seems all of the holes were already final sized from the factory.
What's next? The rudder skins need some additional prep work, then probably some dimpling.
