Had to remove te firewall and bottom fwd skin to install the fwd section of the 704 bulkhead. Deburred the firewall while I had it off. CUt my fings in 4 places on this stainless steel. Fit the F713 auxiliary longerons to the sides of the fwd fusleage, and marked where they need to be trimmed to fit next to the 704 blkhead. Trimmed the 713 longerons. Drew a centerline along the 713 longerons. Clamped the longerons to the side to where the centerline showed threw the holes. Drilled them with the skin as a guide.
