Tonight I set out to rivet the left elevator. First I studied other builders sites for good hints on how to bend the skin tabs. I found Brad Olivers site especially useful for this.
Here I have marked the bend line, and applied doublesided tape to the bending block.
The block in place and the whole thing clamped down to the table.
First I bended the lower tab (elevator is upside down) with a piece of wood, then I finished the bend with a big mushroom-head set in the rivetgun. It was much easier than I had anticipated.
Then I bended the upper tab the same way, and drilled holes for the poprivets that holds them together.
With that all done, I could rivet the elevator together. Still need to roll the leading edge and build and install the trimtab.
