(10-20 step 3):
Now that the stiffeners were done it was time to rivet the side
skins to the frames and bulkheads. I used the swivel set on these
and you really can't tell the difference between them & the
stiffener rivets that were back riveted. The sitiffener is the
horizontal row of rivets, the bulkhead is the vertical row.

came out and helped with the bulkheads in the rear. She shot, I
bucked. Once those were done I used the squeezer and set the
rivets in the aft-most bulkhead. Angela snapped this pic before
heading inside.

Angela
came back out and we tag-teamed the bulkhead & frame rivets around
the bend in the lower portion of the side skins. Here we found a
limitation in the swivel flush set. Since this is a curved
surface and only part of the rubber guard makes contact with the skin
I'm guessing that some of the buffering affect it affords is lost
allowing the face of the set to beat the skin slightly harder. So
we got that small dent in the skin around the rivet. We didn't
like this so we went the back rivet route instead. This was an
interesting feat trying to get the rivet being set to sit flat on the
plate... unfortunately we don't have any pictures, but basically I
would roll the tailcone until the rivet head was flat on the backing
plate and balance it there while Angela would rivet it. Quite
entertaining looking I'm sure. But it worked out well... again,
not the fastest thing in the world, but we like the results
better. Here you can see (barely) the difference between the
swivel set rivet (upper left) and the back riveted one (lower
right). It's more noticeable than the picture indicates.

(10-20 steps 4 & 5):
Next up was to rivet the bottom skin to the frames and
bulkheads. I back riveted all of these except for the F-1010
bulkhead rivets (my back rivet plate wouldn't fit between the side skin
overlaps) and the two rivets in the F-1007 frame that you can't get to
with a back rivet set due to the stiffeners. These were all
bucked with the swivel set. After that I began back riveting the
bottom edges of the side skins to the bottom skin. Only got about
30 of those rivets done before calling it a night. I'll continue
with those next time.
