Flap nose skin
Jeff. I built the ugliest aileron known to man! On my 9a.
I had to chuck it and build another one. The upward force
Of the pre-bent nose skin unclamped before riveting to the spar,
created upward force and tweeked and twisted the trailing edge in the worst way. When you bend the leading edge down to the spar, put a board the full length and clamp it down. Clamp the trailing edge down to a flat surface and glue with 3m 5200 quick cure purchased from HOme Depot. 5200 is an amazingly strong marine sealant. Use gloves! It's equally bad as pro seal to deal with. The trailing edge ends up straight as an arrow. My recommendation is glue
The trailing edge before riveting.
