On May 27 my father and I started working on the Firewall since we did not have enough time remaining prior to their departure back to South Texas to finish all the rivets in the Mid Fuselage Ribs and Bottom Skin.
Quickly we had the Firewall assembled with clecos. Then my help left so back to a one man shop :( I worked as much as possible on the Firewall during the weekends and finally got it finished except for attaching the heater vent valves that require the Biotherm 100. Besides the firewall stores nicely sitting on its face until it gets attached to a larger piece! 20 hours time.
