DIY Rocket Stove for Camping
John Fischer packs his portable rocket stove every time he hits the trails outside of the German city of Stuttgart. By designing a detachable feeding tube, combustion chamber, and grill grid, he produced a rocket camp stove that packs down just like his tent.
Materials: Large pressurized canister; 4 pieces of scrap metal for supply shaft; insert tray; 2 metal legs; 2 nuts, washers, and bolts; bolt with pointed head; short cable.
• Empty a pressurized canister completely and measure its length and diameter.
• Fashion a square supply shaft from scrap metal so the elbow “crook” allows for 1/4 inch to 1/2 inch on either side, and so the shaft is approximately 1/4 of the canister’s overall length.
• Cut off the canister’s top, and cut a hole the size of your wood supply shaft in the side.
• Fashion a supply-shaft insert, such as a cut HVAC vent cover or grilling tray, and place it into the vent at the bottom of the shaft to allow unobstructed airflow.
• Use nuts and bolts to fasten 2 support legs to the supply shaft’s end to create a slight feed angle and to correct for uneven terrain.
• Weld a long bolt with a pointed head to the bottom of the tank for added stability.
• Form the grill grate by notching 2 pieces of angle iron to fit together at a 90-degree angle.
• Cut the bottom corners of the grate to seat it within the combustion chamber.
• Paint the entire stove with high-heat paint.
• For additional stability, add a notch to the top of the feeding tube and to the corresponding side of the combustion chamber. Measure a short cable to cross that gap and secure with crimped cable ends.”
