Is edge rolling needed for the trailing edge of the horizontal stab skin when you rivet it to the rear spar? I know it's needed when skins overlap, but should I do it in this case? Thanks!
My opinion is that it's not required here but wouldn't hurt. I didn't roll mine, and the skin sat down nicely on the aft edge.
I'm sure you already know that edge rolling isn't all that aggressive. It puts a barely-noticable tweak (technical term) on the edge rather than a sharp bend.
