I stumbled on this thread when I found a UDS video that Bigmista posted a while back. I'm inspired! I looked at a couple of food grade drums today, but they were closed top and and I'd rather go the easy way if I can. Still, looking at sfbbqguy's finished product is making me think I should just grab the first drum I see. I'm sure I'll run into some snags along the way, but looks like every question is answered in this thread. I'll post back when I get myself painted into a corner.
