Aug 18, 2012 Stainless firewall with lip riveted in place - (30 hours)

Category: Firewall

We cut the firewall out of sheet stainless steel, very thin. Then cut strips of the same stainless with notched tabs which we bent in an riveted to the firewall using monel rivets. Doug has started installing electrical connectors as well as a fuse block. The vertical slots we cut to allow the nose gear supports to sllip through when we pushed the firewall into the shell and against the tubular CrMo cage structure.
