Brief Description: Countersink/dimple firewall parts, begin riveting
Dimpled or countersunk the firewall and firewall structure parts as required. Taped the called out rivets in place, minus the recess and weldment rivets and then back-riveted all the firewall stringers. I am reserving the recess at this time so I can install eyeball passthroughs instead of snap bushings for the control cables. I will continue with the weldments at the next session.
