I made my own woodstove for camping, primarily in my tipi. I used a side box for a large charcoal grill. It has worked like a charm so far. I have been able to sustain 500 degree temps very easily. We get tired of smoke in our faces when we go camping in the tipi. Couldn't see paying $300 and up. Thought you might want to see what keeps me going when it warms up outside!
