I think you will be fine. Try using the minion method so it doesn't get too hot. Basically looks like this:
It's crazy how the Smokey Joe fit. It puts the coals at dang near the exact same height as the original coal tray with the same gaps around the sides. I was curious about that gap myself when I bought the ECB aswell as the lack of a coal grate and air holes for the coals. But it was almost like the smokey joe was designed for this purpose....
I'll get some pictures of it during it's inaugural smoke...And mine... (Doing baby backs and a butt, by the way... Also gonna try them Wicked Beans I found on here...)
I like the legs on the coal tray there Duke. Looks like it meets the purpose. Did you drill any air holes in it? I am worried about temp control this weekend....
I throw an old soup or veggie can in the middle (NO LINER) and throw wood chips/chunks in there to make sure I keep the smoke going.You can be sure that the Butt will need three or four adjustments to the charcoal in the pan.
Are you doing 2-2-1 with the ribs? Best way I ever found!
Don't forget to take lots of picks and do a post on all of it. Some folks do it as they go along!
