After a long and hot couple days at Oshkosh, Chris and I finished the bucking of the firewall supports. Shannon helped hold the parts while I squeezed all the rivets I could reach. 10 hours seems like a lot of time, but there was a number of parts to fabricate and fit on the support brackets. Looking forward to the center-wing box. Just when I am anxious to make progress, I have a business trip this week. ugh.
