27 A firewall held together with cleco

I would have liked to rivet the firewall together tonight but there is simply not enough time.

 Here we go again with the sticky stuff

 Putting the proseal into a dispenser was way easier than expected :)

 I decided to try and place the center piece in at the same time, it worked even if I had to remove clecos on one side at a time to put the tunnel sided with stiffeners in place

 Back riveting the first 5 rivets per the plans went great

 Then I found another mistake, four rivets done that should not have been, luckily it was possible to remove them without taking everything apart

 Match drilling

 Ready for riveting
