Drilled out the worst rivets from yesterday's go at the seat ribs to F-905 to baggage ribs. Used pop rivets in a couple places and one hole was so far gone that I used another AN3 bolt. Some of the rivets are marginal (a bit of clench-over), but I elected to leave them as-is given the difficulty in drilling them out without hole damage.
With Karl's help, bucked the rest of the rivets satisfactorily--ctr section skeletal rivets are done.
