Took a week off for the 4th - had to go up to Kansas to do the fireworks thing.
On my previous entry, I thought I was ready to rivet; then I remembered the trim tab was to be mounted on the one elevator that I had ready to go.
Drilled the skin using the trim tab hinge as the template; then up-drilled to #30. Completely disassembled the elevator to deburr inside the skin; cleco'd all back together. NOW I'm ready to rivet.
