Here is what I'd do (and might do.) Get some 3/8" rebar (10' => $4 at Menards) I'd bend 6' into a circle (details left as an exercise for the student.
) and weld the ends to make a ring that would fit where the top grate fits. I'd take a couple more pieces and bend them so that they could be welded to the ring and make a couple supports that would extend about 6" into the dome to take advantage of that space.
Then I'd have to figure out how to make some hooks to hang meat from. SS would be nice. I wonder if a bit of SS bar could be purchased ...
