Started riveting the RH side skin. The plan is, rivet the RH skin as much as possible solo, then get a friend (Son) to help with the ones I can't reach (which will be the lower line between the middle three bulkheads) Then I will put on the LH skin and reach up to rivet as much as possible solo...then get my son to crawl inside to buck the rest Also, I added nutplates to the aft baggage compartment bulkhead wall.
Top row of rivets going in
Top row completed
By the way, the longeron was backriveted to the skin prior to installation.
