>"I am more positive about your stove than you are."
Thanks Derek. Don't get me wrong, I think this stove (help need a name) is definitely superior to the bushbuddy for me. It's more compact, lighter, more effective in the wind, and easier to use with the bigger fire box. Plus it's cheap and easy to make. Others will decide for themselves.
>"My concern with your stove is whether the Aluminium outer will soften and collapse if the fire is prolonged."
I think it should be fine. I've been playing with different designs for the fire box for several months. But I used the same aluminum outer the entire time. Unlike the bushbuddy there is no heat conducted from firebox to outer. The only connection is the titanium stake touching and that doesn't seem to be enough. Aluminum definitely doesn't work for the firebox (tried this and it burns away).
>"I would make the outer taller to encompass the pot and increase the height of the chimney."
The height of the outer is as tall as possible while still fitting in my pot. I could do a split design to extend up the side of the pot. How much difference that would make? Would it be worth the extra fiddliness of having another piece to the stove (there are 5 pieces so far including 2 stakes)?
Hi Herman, I've followed the debates/tests of double wall stoves. While I haven't seen anything conclusive I see no evidence of any advantage for the outer wall to justify it. The design here is different though. The outer wall of my stove provides a windscreen, chimney, and pot stand for about 1/2 oz. I think that's well worth the weight. I also doubt the aluminum oven liner producers have noticed the uptick in sales based on my efforts. :)
