Section: 27
Hours: 4

I thought about how to get to the rivets next to the tunnel walls last night and here's my solution. The long flush rivet set to the rescue!

The area where the center panel ties into the other panels was the hardest to rivet. It was hard to get the back rivet plate / bucking bar into the corners to make sure the rivets stayed flush.

Here's the nicely curved tunnel face at the firewall.

All the rivets are flush on the front side of the firewall.

Here's what all those rivets are for- lots of structural angles on the back of the firewall. That's it for section 27!
