Plans say rivet forward and rearward from the704 so today I decided to rivet forward on the stiffeners. I'll rivet these to withing about 8 inches of the firewall. I will still be able to pull back the firewall to apply sealant.
I noticed however on the F719 stiffener that the aft end had an indentation in the skin due to how the stiffener bends up on top of the angle. So I made some shims to smooth this out.
The auxillary longeron uses 1/8 flush rivets. I had to turn my pressure up to 60 lbs to get a good fast shop head.
