Very nice, and should last a long time to boot.
I too feal that nothing is scrap (just ask my folks, they call me sanford
) At any rate I've been thinking of building a OWB using an old fork truck wheel that we're scraping out at work as the fire box. The wheel's 30X36X1.5 thick (no tire pressed on just the steel rim) and the best part is I can pick it up cheap. I really enjoy building and looking at stuff like this, really gets ya thinking about just what we spend our money on and just how much of it can be had a lot cheaper with a little time and some imagination.
DO IT!
