Finished riveting right leading edge ribs to the main wing spar. Like I thought, the last few ribs weren't so bad. The outboard most two could actually be squeezed. There are still 2 rivets to get to after the aluminum angle that is supporting the spar to the wing stand is removed, after I've moved the wing to the new wing stand. Then I riveted the skin to the main spar. Squeezed all of those rivets in a jiffy. Did another tank test and I'm not sure I've sealed all the inlets and vents and fuel cap completely. I'll get a spray bottle and see if I can see where I need to seal better. Or, I have leaks and I'll find those. Bummer.
