After working on the longeron and the clearance for the spar bolts I spent some time making spacers for a few rivets on the tailcone. There are a few spots that had a slight gap between the skin and the bulkhead flange. These gaps need to be filled with a spacer so the skin does not pull down and pucker.
There is one spot where I did not catch the gap untill after I riveted the skin down. I drilled out the rivets, but the hole got a but oversized so I will have to put a larger rivet is this spot. Not a big deal.
