I finished with the clecos on both rudder skins to the rudder assembly, match-drilled some holes for the plan, and focused especially on the trailing edge. The trailing edge of the rudder has a small wedge shaped strip that extends from the top to the bottom. It fits between the two skins, so it terminates as a strong edge.
The holes in the trailing edge of the skin, going through the trailing edge strip, had to be match drilled perpendicular to the chord. It took some work moving the cleco'd assembly but I eventually got it to sit at an angle such that the chord was parallel to the deck.
Once drilled, I disassembled, removing every cleco and marking orientation of parts as they were removed. I then dimpled every piece that would contact the rudder skins using mostly the DRDT-2 instead of the squeezer, because it makes for faster work.
Next session I'll dimple the skins and countersink the trailing edge strip. Then debur everything. Then prime. Then rivet.
