Well, you can go from J tube to horizontal batch rocket. , that's already an adjustment variable. Then, your heat riser needs to be insulated, and in a metal radiator, thought, you can also use a bell. , ok, you might need a more reactive heat riser in a bell. Ie, first third of thin refractory, and the rest made out of stainless steel. Realy well insulated. While on a J tube, with a barrel with the proper gap, the draft might be increased by the "radiator" (barrel) therefor you could be a smidge more lousy on the heat riser insulation. Or have more mass , ie, heat riser made out of bricks. . Then, your bench can be made out of cob, and pipes, but also from half barrels to form a bell. Or else, a proper brick bell, which is diferent, but will still work in the end. Let say, you use a nice stainless steel, polished or engine turned compressor tank, for the barrel. And you don't have a oil drum in your living room anymore. If your mass is big enough, you wouldn't have a high enough temp to scorch wood, so you could use wood panneling to hold your cob. Or may be bricks. Or else, stones. Then may be you want your mass bench to be a bell, and use concrete blocks, which you could cover with teracota tiles, or floor tiles (i don't know how to translate faience) Cover your mass with portuguese azulejos for example. The ultimate limit is "does it still fit with the desingn of a rocket stove? " ans what can you afford? Or what will your imagination be able to come out with. Frankly, you can do pretty much anything, providing you provide enough thinkinh into it. And you're not too short on moneyy. So you can't escape the scavenged materials. Even tho, scavenged stuff, if you put enough time looking for parts, can look wonderfull too.
