Well, like it says in the subject line, we are talking about
skin to spar rivets :) I didn't have any problem with
the stiffeners.
The bend in the skin bulges outward when you hold the
skin open, which then prevented me from generating enough
pressure with my free hand to keep everything pressed
onto the backrivet plate.

Paul,
I took some foam blocks and sponges and wedged open the skin so the top and
bottom were open about 90 degrees. The top skin was sitting on my back
riveting plate and the bottom skin was sticking almost straight up. I then
took the long rivet set that came with my Avery C-Frame tool, placed it in
my rivet gun and back riveted the spars to the skins. Contact me off-list if
you'd like to receive a photo of how I did this.

I did not back rivet the spar. I set the elevators upright in a cradle with
the trailing edge up. then reached in from the top to rivet the spars. I
did not have any problems, but I did not spread the skins apart at the
trailing edge any more than necessary to get my forearm in to buck the
rivets. I am having a hard time understanding how you would back rivet the
skin to spar.

I just riveted my right elevator spar to top skin and it came out OK. I first
hand squeezed as many rivets as I could (22), then I clecoed the trailing
edge of the bottom skin to the table and pulled the top up to 90 degrees. I could
then reach in with a bucking bar and rivet the remainning rivets.
Worked out great.
