I got the patch made and welded in. That was a job i wish to never do again.
Welding upside down, in a confined space, laying on cold concrete, having to reach around the driveshaft, swaybar, and exhaust pipe, all while the spatter rains down on you is no fun. No my best welding effort for sure.
I made the panel and then put a gentle bend in it to match the transition between the two floor panels.
Holes were punched down it's length for the spot welds.
I then temporarily screwed the panel in place to clamp it as there is no other way to hold it in place. This pic is when I am about half way done installing the screws. This also help flatten the panel down to it final shape.
After all the screws were in, I went about and flatted the flange anywhere it wasn't laying completely flat against the existing body structure.
I went around and pulled out one screw at a time and then welded hole shut. So basically plug welding the two panels together.
When done, this is what it looked like from the top side.
I sprayed the patch panel and the area around down with some primer. Once that cures, I'll go back and seam seal the outside of it.
Also, I run some seam sealer down the inside of that groove where the rust line was to protect it, before putting the replacement wood in place.
It's done, and let us never speak of it again. I also have a work shirt that is now swiss cheese from the welding spatter.
