Firewall Modification for Viking Steel Spring

Drilled out and added doubler to 7F7-1SP firewall upper channel to accept Viking "steel bungee". Installed upper nylon bearing into upper channel with 4 AN3-6A bolts.

Firewall (7F7-1) Layout for Viking Steel Nose-Wheel Spring

Firewall & Viking Steel Spring Nose Gear Components (Powder Coated)

Cold-snap. Worked in office on firewall components lay-out. Scribed firewall (7F7-1) reference lines. Scribed rivet lines on vertical lower channel (7F7-2C), vertical top channel (7F7-3) left & right firewall stiffeners (7F7-5), and top channel stiffener (7F7-7SP). Scribed rivet locations and bungee pin holes locations in left & right channel doublers (7f7-8C). Verified pre-drilled left & right gear gussets (7F7-9C). Since I am replacing the elastic bungee supplied with the Viking steel bungee, laid out locations for 9mm mounting holes for the upper viking gear assembly on the upper channel (7F7-1SP). The upper channel supplied with my kit came pre-drilled for the spring/gear-tube assembly. Dis-assembled the Viking spring assembly, primed, and painted mounting legs and spring.

Port-Inboard Slat (7F1-2) Skinning

Port-Inboard Slat (7S1-2) Underside Skin

Laid out and inserted center slat rib into Port-inboard slat skin. Cut slots in skin end ribs with mounting flanges. Critical dimension 1204mm flange to flange - will match slat mounting flanges in wing. Drilling for center rib requires 2 sets of hands to hold bend while drilling. Thanks Brett
