I must say these pictures are an inspiration. I can weld, and I can do work like shown (almost), but I rarely have the patience to do it that great in a place where it can't be seen. I remember fixing a floor pan on my orig Camaro, spent more than one day bending to get the right profiles, and nobody will ever see it. Is it worth it? Not if you do it for a living, but if you have time to do it on your own pride and joy, that's great.
One question. Some pictures indicate that you haven't fully welded on mating surfaces, only spot welded, or was it just WIP? I always weld fully, is there a reason not to, can it get too solid so it'll twist other things?
