Obviously, I know very little about cutting steel. You say one can use a circular saw? What kind of blade? And a cutoff wheel is mentioned - do you mean a cutoff wheel that one might put on an angle grinder? Or can you put some sort of cutoff wheel on a circular saw? Thanks!
Best part about angle grinder is lack of heat keeps warp down. Don't try to cut through on first pass. Etch on the first pass all the way around then go a little deeper on each consecutive pass. Leave couple inches from corners on top and bottom uncut until door hinges are mounted. I also did not cut all the way through the sides full top to bottom until hinges are on. helps holds tank and door in original shape.
