The shape of the iron clad prevented me from using a break to bend the 90º so it was TIG welded using a corner joint.
A corner joint on 14 gauge is pretty darn small and the smallest filler rod I had was 1/16". I wanted to use filler because
autogenous welding would have resulted in a radius corner after blending. I wanted a one piece look when done.
This ArcZone tungston grinder does a fine job prepping tungsten.
The weld joint was close to 74". To maintain the corner joint small autogenous tack were done every 6-8".
The welding was done in back step fashion to prevent warping keeping each bead about 3-4" long.
A close up shows the weld joint compared to the filler rod.
After blending, the corner joint presented with a nice sharp corner giving the ironclad a one piece look.
The same three holes were transferred to the ironclad with the center hole indexing onto the pin (headless nail) still on the header.
The right end fit with paintable silicone sealing the entire edges.
The left end. These small 1-1/4" screws were used to secure the ironclad until the silicone cured.
A view of the bottom return.
I sourced some old school square head 5/16"X 1.5" lag screws as well as five cast iron star washers.
Each screw was removed and the metal was drilled to 5/16" and pilot drilled for the lags. Prior to setting the lags the holes were filled with the same silicon to prevent any water from entering.
A close up of the lags and star washers. you can witness the silicone seal around the heads. A bead formed under the star washers in sure because I pumped a generous amount prior to driving in the lags.
The overall ironclad installed. This will be left to rust naturally and will match the four front garage doors. The star washers give a nice focal point to the main entry. I no longer will have to worry or paint that header.
My wife idea, my execution.
Next up, delete 8 exterior window and replace all exterior doors with commercial steel frames and doors that swing out.
The front main door will also be upgraded. Im still designing it. The house is undergoing hardening to keep parasites out.
