I removed the gussets and did all the deburring, cleaning, priming and riveted on the platenut.
I finished the 902 bulkhead all the way to platenuts which included edge treatment, deburring, cleaning out the longeron grooves, sanding down the little flange by the 5/8 hole, cleaning, priming and riveting on the platenuts.
I also removed and prepared the F-719 stiffeners. I took them all the way to riveting on the clip in the forward end.
