i built a similar style stove that works for wood burning and for a wind screen w/ alcohol stove. mine is just a cylinder that fits around a snowpeak 900. I can boil water on a hand full of twigs in about 5 min, and it takes about the same to boil with my pop can alc. stove. i will have to get some pics taken soon. It is about 10 inches tall and has vent holes, and a place for me to add wood when i need it, the pot sites all the way down and rests on the rolled rim around the top.
