I finished riveting the bottom skin on the left ring. I didn't rivet the rear spar line yet at the Aileron (can't do the flap yet anyway). I can get that with the squeezers. I was able to rivet the rest of the bottom skin with out lifting the panel. My arms are long and skinny enough to get to all the rivets :-). Even getting up through the rear spar lightening holes was no problem.
