Measured, drilled and deburred the flaperon trailing edge rivet holes. Ted came over with solid rivets, a rivet cutter, and a rivet squeezer. He cut most of the rivets and I installed them in the first flaperon before lunch. I worked alone on the second after lunch and finished the trailing edge rivets. Then I measured, marked and drilled the holles in the flaperon counter balance weights and then marked their location on the flaperons. I test fitted the end caps, which will need a lot of work to make right. Got the landing lights today, and came up with a mount idea in the wingtips.
