Did it, do it, and so does anyone else that has to heat structural steel, to
either induce a sweep or chamber into a beam or to remove such after being
damaged.
See, that's what I do, structural steel fabrication.

Which clearly shows you don't know what the heck you're talking about.
However, if I can dig up a digital video recorder and I have some time to
waste perhaps I will do so. Because unlike you I know what the results will
be because I've already done it and not dependent upon my ignorance as you
are.
