This morning the right elevator skeleton started coming together:
Then the skin got clecoed on and match-drilled:
As did the elevator horn:
Oops! Here's the first mistake on the elevators. I followed the instructions and drilled through the counterweight into the E-703 and E-704 ribs, but the drill got off-center and the resulting holes in the rib flanges are too close to the edge for the nut that's supposed to fit there. I thought about elongating the holes, but decided against it. That means I get to buy a new counterweight and two new ribs on Monday.
Then I repeated the above steps for the left elevator, and it all turned out okay. So at least I don't have to redo the counterweight ribs on both elevators.
