Brief Description: Prepared Faux-Firewall for installation
Prepared the Faux-Firewall for installation. 1st off I needed to cut out 2 additional points where the 6 point motor mount contacts the original firewall and the underlying braces/attachment hardware. I did not want to sandwich the faux-firewall and it's insulation between the motor mount and the firewall hardpoints. Then figured out where to place the rivets to attach the faux sandwich to the original firewall. Match drilled and clecoed all of the rivet attachment holes, Then disassembled and deburred everything I could reach (The rivet holes on the bottom are under the floor and are covered) I dimpled the holes across the top of the FF for AN4 426 rivets. I couldn't figure a way to dimple the remaining rivets so I'll attach them w/ CS4-4's. All of the rivets are on the perimeter except for a few to insure contact between the 2 pieces and the Fiberfrax. I polished the Faux firewall with some MetalAL and then glued the FiberFrax to the back of it. I'l let it dry over night. The 'glue' is NOT very sticky and dries to a 'crust' I roughed up the stainless steel somewhat but it's not the best surface for adhering this type of high temp glue. I really only need it to hold things together while it gets riveted. Tomorrow I'll rivet the 2 pieces together. Oh yeah, I should mention the reason I'm doing this is to create a heat barrier between the engine compartment and the cockpit, to mimimize the potentioal for Hot Tunnel Syndrome HTS!
