Brief Description: Dimple and start riveting structure to firewall
Dimpled the firewall and countersunk the angle pieces that attaches to the aft section of the firewall. Started riveting the pieces, which proved a little difficult to back rivet with the bend in the firewall causing lifting. After drilling out 4-5 rivets I bucked the top row, except for the nutplates. I suspect the lower rivets will not be a problem.
(Still waiting on the 2 sections of 13 holes that listed to hold off on match drilling and riveting for the longerons)
Structure on aft firewall
Flush rivets on the forward firewall
I love how crisp the dimples are on the Stainless Steel
