Cleaned then primed the Firewall spars. Match-drilled the upper and lower, left and right side engine mounts. Assembled the components and secured them to the bench in an upright position to assist for riveting. I had just started on the riveting when Mike S. showed up to help out. It went much faster with two people; however, it was do-able by myself but slower of course. It was good to have the help. Now it's on to the next bulkhead behind the Firewall which should be the massive F-704 Center Section which is the heart of the fuselage where all things attach.
