I looked, but couldn't find a thread on this one, so hopefully other folks have the same thing to post with a couple of pictures. I went to a restaurant supply for a 2 quart stainless steel container, seemed about the right size for the 25 lumps I need. The coffee can type will rust out over time, but this should be good "forever" for me. It's about right for my 12" DO. Went to a hardware store for some bolts & nuts. I drilled the stainless with a few holes in the side & bottom, used some scrap tin for a heat shield, cut a hunk of 1 1/4" closet rod for a handle and here's what I have. Had to use small carriage bolts to make the "legs" to lift it up for better air-flow.
