We have a firewall! I started the riveting on the bottom of the firewall using the squeezer. Almost the whole bottom row of rivets can be set with the squeezer using the longeron yoke. Some of the rivets on the 601J angles are too close to the angle's bend, so they had to be backriveted. Sort of a bad picture here, but you can see the longeron yoke does a great job of getting around both flanges.
The rest of the firewall was backriveted. I used a couple of 2x6's to raise the firewall off the table, set the backrivet plate on one, and a piece of 1/4" kindling stake to level it on the other. Didn't get a picture of that though...
Rivet tape.
Here is the finished back side of the firewall. This side faces the cabin.
Here is a couple shots of the smooth front side. The recess will get riveted in later. This is so access is easier to the inside later on when the FW is in place.
