This cook stove is a valuable piece of equipment for any camper,  hunter, fisherman or outdoorsman.   It is rugged, portable, and compact.  It eliminates the need for propane, liquid fuel, electricity and large stacks of firewood, or wood pellets.
NOTE:  For Outdoor use ONLY!

Parts Needed:
1 – Wall thimble for 4 in. ID pipe
1 –10 inch long connection T- pipe with cap
2 – 3 inch extenders
1 – 4 inch adapter for connecting to 6 inch vent
1 – 6.5 in. diameter gas range burner grate

Tools needed:
None

Assembly:
•    Place the wall thimble on its side, on a level  9 inch square surface.
•    Slide the T-pipe into the top opening , with the clean-out cap facing down.
•    Twist the 3 inch extenders onto the top and T (feed tube) openings.
•    Twist the 4 to 6 inch adapter onto the top  of the 3 inch extender.
•    Place the gas range burner grate on top of the 6 inch extender.

Starting a fire:
Remove the burner grate. Feed the initial combustibles down through the top, making sure that there is two to three inches of fuel from the bottom.  Use a stick if needed to push the kindling down.  Do not tightly pack the kindling, keep it loose.  Leave space in and around the kindling for air flow. Wad up one or two sheets of newspaper, or  use dry straw, dead leaves, dry grass or other combustibles, as you would for tinder when building a campfire.   Once done, feed in kindling (smaller twigs, less than 1 in. in diameter,  12 in. or less in length. No more than a total of 2 inches thick) also through the top.   Light the kindling from the side feed (T- extender) opening with a match, lighter, or magnesium fire starter.

Maintaining the fire:
Once lit, begin feeding more tinder into the fuel feed tube.  Once the fire is established,  place the burner grate back on the top.  Then feed more fuel, up to 2-1/2 inch in diameter, only into the fuel feed tube.  Keep the fuel length close to 12 inches in length, and feed it into the fire as needed.  You can use sticks, fallen limbs, scrap (non-treated) lumber, pine cones, charcoal, coal, nearly any solid combustible.

Cooking:
Cooking is similar to a kitchen stovetop.  Temperature is controlled by varying the diameter and amount of fuel used.  Larger diameter sticks burn slower, therefore generate less heat.    Do not over-heat, as this wastes fuel.  


Emptying ashes:
Since the depth of the T-connection is longer than “conventional “ Rocket Stoves, you can normally cook for about 2 hours before needing to let the fire die and emptying the ashes.   Be sure to let all the embers die out and cool before opening the cap and dumping the ashes.  
NOTE:
DO NOT empty ashes onto dry grass, or exposed tree roots, as this may catch fire if all the embers are not dead.  Be sure to douse ashes with water, then stir to make sure all the embers are out.  
Repeat  this process three times, to ensure all embers are out.

Operating TIPS:
•    Face the opening of the feed to toward the wind, to take advantage of natural convection.
•    Control the cooking temperature by varying the amount and thickness of the fuel, and feed rate.
•    If you cook on the grate without a pan, be sure to prepare it with vegetable oil first.  Turn meat frequently.

Care and maintenance:
•    Empty the ashes after each use.
•    When not in use –
1.    Store in a shelter (garage, barn, shed, camper, etc.)
2.    If the connections become difficult to twist, clean with a lubricant (vegetable oil), wipe clean with a paper towel (save for use as tinder  for a later fire).

 
How do you know how fast it boils water if you haven't built it yet?<br><br>Also what is the insulation here. Rocket stoves work because the burn chamber is well insulated.
<p>MrSteele10,</p><p>Excellent questions, thank you. I have a small backpacking stove from 1969 that boils water in less than 4 minutes, this has a similar heat profile diameter, plus the intake pipe facing the wind will heat up like a bellows for a forge. What? If it takes 6 minutes its no good? LOL! </p><p>The pipe is double walled. I have the same pipe on my pellet stove, and I can grasp it with no heat transfer to my hand when it's working full-out. Same pipe, same principle. Go to your local woodstove store - and talk to the sales people there - let them show you the double-wall setup.</p>
Awesome! Where's the finished product?
If you've priced the component parts, you'd know. It's well over $350 plus tax for all the pieces ... so it's still at the Stove Shop! Probably THE most expensive portable, but cool to the touch, rocket stove ever designed. Just not cost effective.
I wasn't asking about the price just about a complete instructable. But since you brought it up why in the world would it cost $350?
Sorry .... it is a one-page instructable - since the components basically just screw into each other. <br> <br>The parts themselves (double-wall stove pipe) are pricey - the T-elbow with cap alone retails for about $79.00 USD. The least expensive piece is the gas range burner grate .... for around $7.00 USD. If you can find less expensive pieces - definitely get them. We have a pellet stove at home as a supplement to our home heating system. When I went to the stove shop, and put it together from pieces they had there - my stove guy was amazed. When I priced it out - I was flabbergasted! LOL. You can also make one from triple-wall pipe which will cost even more, and be heavier. <br> <br>The &quot;rocket stove&quot; functionality concept is the same, regardless of what it is made from. If you know of a store that makes ceramics and has a large enough casting oven, you can even make one from terra cotta clay (like the chiminea sold at the Lowes and Home Depot stores, but on a smaller, more portable scale).
Awesome! I have made a small rocket stove with a cooking oil can and a heat duct elbow, and it takes a few tools and measuring. Strong hands required! :) In the oil can type, you feed the kindling and other wood in the bottom pipe, but in yours you add from the top. I'm not sure why. Have you found this to work better? Less smoke?
Earthlove, <br> <br>Thanks. No, you only START the fire from the top. Once it gets burning, put the cooking grate on, then feed from the elbow. The inspiration for this style comes from &quot;the Deadwood Stove&quot; http://www.deadwoodstove.com/ <br>I like their style, but the entire stove gets too hot to touch, and can be a hazard. I've been a wood burner / pellet burner to heat my home for over 3 decades. When I saw theirs - I immediately knew what my design should be. <br> <br>It can boil a quart of cold water in under 5 minutes.
