I have been trying to find a wood/alcohol stove that would nest inside of my current pot. I primarily use the IMUSA four cup aluminum mug and have not found any stove combination that fits inside of it nicely.
Recently, I was looking at Jim Wood's site and came across his Fire Bucket Stove System. I really liked the concept of a dual purpose setup that could be used with an alcohol stove or burn wood. My only issue was that it still would not nest in my pot. After playing with it for a while I came up with this design. It is two strips of four inch wide flashing that can be used separately as a wind screen or nest together for burning wood. Tomorrow will be the big test to see how well it works.
