Today I riveted the ribs to the tank skin. The main ribs I used a bucking bar and rivet gun to set the rivets. I removed every other cleco and then dabbed sealant in to the dimple. Then set the rivet. Then removed the remaining clecos and repeated the process.
The end ribs I used the squeezer. I did the same thing as the other ribs, removing clecos and dabbing sealer.
Finally, I wiped down the outside to remove all of the smeared sealer.
