Here is where I screwed up. Welding the back side. Remember there is double lip coming up about an eighth of an inch, that why the weld looks to high. Anyway, I forgot what the hell I was doing and since the welding was good, I forgot to do a little at a time. So, I got some warping to deal with later. Back side pics.
