Lots of tricky rivets

I had saved some tricky rivets on the ends of the top skins and then there was the end ribs... I think it was 24 rivets done tonight, took almost 2 hours!

Tried ti find a way to use the C-frame, no luck

Could it be back riveted, maybe but it would be at least as tricky as normal riveting

Ended up using the back rivet set against the man. head, result: only a small dent in one of the four places

Then the swirly mushroom set on the edge rivets

Next are the end ribs, can you fit the squeezer there? no...

Ended up using the extended back rivet set from one side and a bar on the other side (even ut beeing 470 rivets)

Ok here where I could fit the tungsten bucking bar

Here you had to go from the other side as my bar would not fit, used the bolt to make sure the parts stayed alligned

Did set the bottom one first as it could be driven from the "right" side
