Started by drilling out and replacing some rivets in the bottom skin that were either grossly overdriven or bent/sheared.
Then there was a small triangular section of the bottom skin and side skins that still needed riveting. Picture shows top rivets not yet set, and bottom rivets (except for one), already set. Looks like another bent/sheared rivet I may replace. Bucking bar control is a little hard in some of those tight places.
Then I riveted the small aft bottom tailcone skin in place to the side skins and bulkheads. This went much easier than expected, enough room for a small bucking bar held through one of the lightening holes in the forward bulkhead of this small aft bottom skin.
