Brief Description: Finish Drilling Longerons, Hang Firewall
Drilled the #30 holes in the forward ends of the longerons. Marked the centerline on the flange of the firewall support. Made the four F-704 straps per the plans and drilled them to fuselage. Marked min edge distance for the upper end (longeron end) of the strap and used that to position and drill first hole. Cleco'd in place and match drilled other two holes with fuselage. Repeated process for all four straps. Clamped firewall to forward fuselage to check fit. All looked good and I removed firewall. Began prep of lower skin by removing blue plastic.
