Leak test
All good this time; one screw in the inspection hatch was leaking but a quick tighten and we were done
 

Fuel tank bolted, torqued and the screws fitted to the fuel tank
 

Dimpled all the ribs for the top skins (dimpling of rib holed for bottom skin still to do)
 

Scarf joint
I was a little more brutal this time around and it go the job done quicker.  It took ages last time.
 

Inboard top skin clecoed on and riveted
You can see from the second photo how many rivets that myself and Bob managed to do before the end of the day.  A couple to drill out, but the 3lb bucking bar and large offset back riveter work a treat on this part of the job
