Step 3-5 in Sect 9-12: Built the Elevator Trim Pushrod. Key is countersinking both sides, and performing "double" flush riveting. Pleased with result, but I used slightly longer rivets... -4 instead of -3.5. The shop ends filled the countersink better (not sure 3.5 would have even worked !).

Step 6: Trimmed away excess material on Trim Tab Horns, and deburred. Dimpled ( after first cleco'ing to Trim Tab Skin and final drill the #40 holes)
Sect 9-13 Steps 1-3: Cleco together top and bottom Trim Tab Skins with 2 Foam Ribs, TE, and Trim Tab Spar. Insured Close Out Tabs on top were on outside. Dimpled 3 holes each end, then drilled to final size with #33 drill (for blind rivets...later).
