Bent the closeout tabs on the trim tab skin and drilled the trim tab horn parts to the skin and spar.
On the elevator, I had trouble with the inside bending block slipping, even though I had two strips of double-sided tape on both sides. This time, I tightened the clamps with channel-locks, and the bending block didn't budge. The increased clamping pressure made the taped blocks a bit challenging to remove, but not so much as to bend the skin.
Outboard end ready to bend.
Outboard end complete.
Inboard end complete, and horn drilled to skin and spar.
