Step 1: 1000 Mile Hiking Begin With Small Step
Because I like to be/sleep in warm. and winter camping is (could be) very cold, well i must add a heater in the tent.
But which one. It in a common sense to burn wood and cook and heat yourselves on site. But open fire is open fire and you need a ton of wood to hold through night. Better and good efficiency is a stove - save wood and generate heat and you cook with clean pots.
Best combustion have a rocket stove, practically without smoke/sap, Must be small but save, Well, so it be.
I made my own idea drawings and start to assemble a stove.
A common packing metal tape was used for small L shapes which are with popup rivets bonded on the inside part of first triangle. All others triangles and forms are prepared as this one.
Step 2: Assembling...
In the rocket stove in the combustion chamber (burning place), wood burn totally fast and chamber achieve a very high temperature. Therefore I decided to make this chamber from two layers of metal sheet to get roughness and durability. Then I make holes inside chamber to have vortex air flow and cut out an opening for wood entrance.
Step 3: Assembling
All parts are equipped with "L" pc's and with 3mm popup rivets connected to both sides. Bottom and back plate are 2 cm wider then inside sides, to achieve distance and lower temp.- security step to avoid accidentally possible contacts sleeping bag or other camping fabric with hot insides. Therefore I have a heavier stove.
Step 4: Assembling...
At last, outside cover is bend and with 3 mm popup rivets connected to main body. Dimension of this cover is also with air distance 2cm from both stove sides. Small square throat shall be added to hold a chimney.
Step 5: Assembling...
Adding a part which troat hold square chimney on stove.
Step 6: Assembling a Chimney
Square chimney was difficult to prolong (stack) and it was to heavy. Also it shall be difficult for cleaning, So, after first field test, I decide to make a round tube chimney made out spray cans, Collecting same diameter, same steel material. cutting, rolling. point welding... assembling.
Well, this was a first my attempt in this skill and I learn very much, correcting mistakes, so today I have great respect for this profession.
Step 7: Assembling Tent Wall Heat Protection
Inspite that the chimney have about 80 C surface on 1.2 m high at normal draft, I decide to add a can which can slide and made a distance from tent wall fabric and chimney when he pass through tent wall. Later at testing, I measured can surface heat about 30 C...
Step 8: Assembling - Adding a Candle Heater to Stove
What about sleeping in hot tent.
If you add every 15-20 minutes an wood in stove to keep fire running, you can not go to sleep. If is outside snow, you load a wood in stove all night. I was thinking that I add/attach a part (candle drawer holder) to the stove from outside. which can hold 8 hours tea light candles. 3 x 5 candles shall bring about 450 Wats in the stove and ALL CO/CO2 shell past through chimney... see pictures. Material was 0,5 mm metal and unnecessary heavy....but for test was OK. And it works!
Step 9: Rocket Stove on First Burn...
So, late autumn, outside temp about 12 C I tested rocket stove with square chimney. Everything was as predictable. It was easy to collect small wood max dia 3 cm and it burn correctly. Stove was warm and no smoke. Perfect.
Another day test was inside tarp with out +6 C ... we reach comfortable +16 C inside, but with no wind outside.
But - every 10-15 min - wood is burn out.
Stove is a little bit to heavy for backpacking ( about 4,2 kg) as seen + 1.5kg for candle part.
Material which I used for stove ... steel cca 0,5 mm thickness. Sttove should be made out 0,25 mm thickness metal plates.
As always, better material - higher prices.
It shall be continued....if / when snow came.
