Love it...enjoyed seeing the firebox forming progression. For some reason I thought you might have had a metal break for forming the firebox base flanges...you used good old piece of steel and clamps to accomplish that...something any of us "should" be able to do.
Will follow til the steamup!!

I do have a small metal brake, & ironically I have been looking at a dedicated metal brakes today, I think a 12" would be big enough, they all seem to be one form or another of the same Chinese Mfg. I have decided that my Jensen collecting would focus primarily on older brass tag, black firebox Jensen's & I need better tooling for the firebox's if that's what I'm to build more of in the future.
