Back riveted stiffeners onto bottom skin. Fabricated Gusset and match drilled to rib and trim spar. Riveted 903 and 904 together, after discovering I forgot to dimple the forward most holes in the counterweight skin rib locations in both ribs. Drilled out the two rivets that weren't quite setting right, until I discovered the lack of dimples, dimpled them and re-riveted those, and the rest. Riveted the servo brackets to the trim cover plate, and then the servo to the brackets. Used 4-4 rivets on those. Access was limited, but rivets are acceptable, especially to hold the servo in place. Next will be the spar to the skin, or the counterbalance assembly to the spar. I haven't decided.
