No more excuses. Time to rivet on the final skin. It is the forward top skin. It covers up the avionics. After this is rivetted on you can only access the avionics componenets from undeneath. There is plenty of access from underneath if you don't mind laying on your back with the wing spar in your back and holding your head up with neck muscles.
I looked for ways to rivet this from one side to the other by myselft but no go. It really needs to be riveted from top down on each side. So I riveted as many rivets as I could reach thru the access holes. These rivets show below. Now I need to get a helper.
