Love the table; I may have to steal that idea. I'm even more intrigued with your RF plate, though. I'm doing a small-ish (24" dia x 55" long) smoker, and I've been avoiding the idea of the drip channel because I really don't want to cut up my 3/8" plate, especially not to weld in a skinny little piece of angle. Your bent plate, though...I love it. How's it working out? How did you figure pre-bending dimensions? How deep did you groove behind the bends, and how wide was the kerf? I'm toying with scoring on top instead of on the bottom, then welding it back up to keep the shape.
What do you figure the weight to be? With the material I'm using for mine (all 3/8" plate), and a double-walled firebox, I'm expecting it to come in at about 1500 lb. I can't imagine yours is any less than that, given that you're using 1/2" plate, even without the double-walled firebox.
