Ugly Drum Smoker/Tandoor Hybrid?

I've been reading the forums and the DIYs and all that and I'm intruiged by two concepts - the Ugly Drum Smoker, and the Drum Tandoor.

What I'm wondering is if this sort of thing could be hybridized in some way.

See, here's the deal - I've wanted to own/build a small tandoor for YEARS. I've also wanted to own/build a good smoker for roughly the same number of years. So after seeing a few different things I thought, hey, I could build one of these! But I can't afford to build both. So I started wondering if maybe I can do a 2-for-1 kind of deal, with the right design. Might not be 100% perfect in either capacity, but since I'm on a budget and it'll like outclass anything I own in either regard, I'm willing to make a few sacrifices.

I realize they're almost polar opposites in terms of concept, but since things like kamodos exist that can do both with teh right kind of cajoling, it strikes me that it really comes down to an engineering question of heat-retention and airflow.

So I was thinking, with a 55-gal drum, I could set up a tandoor-like clay/refractory chamber with an adjustable air inlet, in the bottom half, which could conceivably get really hot (maybe not actual tandoor-hot, but a lot hotter than any other grill I own), or if I'm doing my sums right with properly managed airflow stay at the right temp for a good smoulder, and then above that chamber suspend the smoker racks. Since I'm not a competative BBQer I really only need enough space for a few items, so if I'm reduced to one rack, so be it.

So, am I thinking clearly on this or am I perhaps out of my mind? Has anyone ever tried anything like this? Any advice?

Sort of. The first one, the "flower pot tandoor" gave me the idea. I realize the two are very different, but instead of using the clay oven for the *whole* thing, essentually using a small clay oven as, well, a small clay oven on the bottom half, and then for smoking purposes basically using it as a glorified firebox.

(not at the same time, of course. It's an either-or proposition at any given time)

Again, not entirely sure if this'll work. Conceptually it seems like it might but I might be missing something obvious, as I've never built either before.

you're going to lose a substantial amount of heat if your tandoor "chamber" is like a box with no lid - all the heat will escape. i have a chamber built -that became a wood fired oven- using firebricks on the top which are hinged with 316 S/S brackets and bars. Pretty much like an old fashioned trunk. Used to get up to 500deg C after 5-6 hours of firing

I'd use a tapered chamber for the firebox, so it'd look more like a tandoor in that regard. Hopefully that'd help minimixe the heat loss out the top of that, but then I'm not sure if that'd work against me for the actual smoking part of it.

I'll see if caliking has any advice! Thanks!
