I have just stumbled upon this while searching about Transit's and rust area's. I am not a nasty person, but I would seriously be worried about the structural integrity of this/these projects. Seriously 10 out of 10 for effort and not running away after seeing the size of the rust problem, but your metal work and welding skills literally worried me. The welds look bubbly and are probably hollow, if it was just a patch or two it really wouldn't matter, but just due to the sheer scale of the repairs I pray that this vehicle stay's in your possesion and it's never involved in an accident. Even the rear hangers made of the 2mm plate on the bench is bad, you dont even have a holesaw. I was 18 once, full of enthusiasm and loved working on my cars, I too did some bandy repairs but not on such a large scale.
