I compress the edge brtween a 5mm balsa on top and 2,5mm below.
All pieces are covered with tape, so they don't stick together.
Because of the curvature I had to use elastics to hold it in place.

I glued 2mm balsa sticks, where the ailerone will be and covered the top with a piece of plate.
When ailerons will be finished, I will fit everything together.

When building aileron I first place rectangular profiles. Then I place a lath, which serves as aligner for the ribs.
I also placed bottom part of balsa cover plate.

Control handles glued in and a lath which served as aligner removed.
In this case only, steel rod is used for the aileron because it's so thin at the end, usually I also use a bearing.

Sanded a half circle on the wing and covered with 50g glass fibers.
On the aileron, rounded part covered with epoxy + microballons.
