Well... about a week of evenings and I've got a working prototype.
Roughly 10.25" diameter. Current stove pipe is 8' long but that may get trimmed once fitted to the shelter.
Sorry for the crappy cell phone pictures here
Glowing Red. I wasn't able to really get it cranking due to limited time, though the whole body did glow red at one point.
Burning away
Shot of the stove fully assembled except for the pipe. The dual air control was an experiment. A single plate would be much easier to manufacture and allow for a larger door. The leg arrangement allows for the use of a snow platform that can be attached to the legs if needed.
Lesson learned... don't clamp the cylinder too tightly. I didn't allow for thermal expansion and the stove body picked up a couple of creases where it caved. It may also be a good idea on a larger diameter stove like this to up the thickness from .004 to .005 or .006
Next on the list... make a stove jack and install it in the tarp. Do some more burn tests and boil tests to see how it really performs... maybe make a stack robber. Think about a baffle. Get a weight for you guys. The body and current mega-pipe come in around 1.5 to 1.8 lbs without the ends or rods. So I'd guess around 3 to 3.5 lbs total.
