After watching at least 20 videos on making Rocket Stoves, I decided to try my own design. I scrounged up enough scrap materials laying around the shop to make one that works really well. I used A 10 inch piece of 3" stainless tubing
and a short piece of 1-1/4" sq tubing about 5 inches long with a 45% end.
I also used some 1/2" nuts and bolts in case I wanted to level it or use it on a picnic table top and not scorch the wood.
Or I could use a scrap piece of wood in between the rocket stove and my jeep bumper.
