I finally got back to working on the plane after a month's absence. I continued to work on the left side elevator. I got the holes marked and drilled for the root rib. I also marked and drilled the hinge for the rib. I did a much better job this time as the hinge is straight for the entire length of the elevator.

Elevator hinge drilled and cleco'd to the elevator.
