Camp Gear | Hobo Stove
We have seen numerous DIY stoves and often thought about building one. We kept two different size coffee cans and some short 3/16″ rods from another project. Old steel tent pegs could be use (not galvanized or aluminum).
For the outer can we used a regular old can opener and punched several holes around the base, and metal shears for a larger opening on the side, about 2-2-1/2″ across.
We then drilled holes at 90deg from the opening, and at a height just above the top of the opening to suspend the inner can onto, this will act like a funnel for the heat/flames.
The inside can had both the top and bottom removed, this is used as a liner or flu for the heat/flames.
Next the outer can had holes drilled into the top portion for the remaining steel rods , these made up the top grill area.
TaDa your done… we seen several models of these stoves with sand placed between the inner/outer cans this is an option we did not explore but may see how much of a added value the insulation property would add to the over all heat and performance of a stove like this.
We managed to boil lake water in 1degC temperature in approximately 3-3-1/2 minutes once the fire took off.
