2 hrs. forward center fuselage work.

A whole bunch more rivnuts installed.

Starting to rivet the skin to the assembly.  For the outside lines of rivets you should draw lines to understand which holes can be riveted now and which are used later to rivet the inner side skins (thanks Gordon!).  I only riveted the "rivet now" line until the crossover point, because I wasn't absolutely sure if it was ok to rivet those.  I'll check my trove of factory photos (thanks PeterC!) to see if it's OK to rivet more.

Another view.

All cleco'ed up and ready for riveting.

Most are done.
