With a little creativity and a lot of recycled materials, you can make this Tiki Rocket Stove for under $40.

A rocket stove is an efficient cook stove using small diameter wood fuel which is burned in a simple high-temperature combustion chamber containing an insulated vertical chimney which ensures complete combustion prior to the flames reaching the cooking surface. (Taken from Wikipedia)

The Tiki rocket stove came from the idea of combining a Tiki torch with a stone statue for a one of a kind back yard garden stove. It features a metal combustion chamber, deep charcoal concrete mass with a Volcano rock cooktop (of course).

Materials List:
Plastic bucket from local bakery - $1
1 Empty soup can – Free
1 Eight inch scrap metal tube –Free
2 Plastic paper roll end caps from sign shop – Free
1 9 x 12 wood board  1 ½ thick – Free
1 Counter top board – Free from estate sale
1 Bag CHENG Outdoor Pro Formula Mix Charcoal color - $30
1 Bag Volcano rock – Free leftover from gas fireplace insert
2 Bags (120 lbs) of  concrete mix - $8
20 Drywall screws
1 Roll Duct Tape
1 Gallon of water

Table saw
Jig saw
Tin snips
Pry Bar
Wheel Barrow
Rubber Gloves are a Must (your hands will thank you!)

Step 1: Step 1: Create Tiki Face - nose and forehead form:

• On the front of the bucket, measure 2 to 3 inches from the top and draw the nose and brow to use as a guide.

• Use the soup can to locate the opening for the mouth and draw this to illustrate the face.
This is really neat. I will try to scale this up a bit so I can use 6 inch stove pipe. I'll let you know how it goes.
I like that idea. I'm finding the three inch pipe works but think it could be better with more room. Just keep your mass around it thick to keep heat in. T
<p>very cool! I plan on building one for backyard cooking. these stoves are supposed to be VERY efficient. this might also be good for a camping trip. only one problem with that though, it would be very heavy to carry around</p>
<p>I'm a mason and have made manufactured stone. This is pretty awesome, I like the porous look but I wonder if you wanted it smooth and put some vibration to it would everything stay intact?</p>
<p>Some design considerations.</p><p>Contrary to what some think, &quot;heating up the entire mass&quot; is pointless and wasteful. What is needed is a graduated combustor - effectively a flue that is made from mostly inert material that has a low thermal conductivity, with an air gap and or or a low conductivity support / retainer / artistic rendition - to support the combustion chamber and flue.</p><p>.</p><p>This design as it stands is kind of like heating 50 litres of water, to make one cup of hot water.</p><p>.</p><p>Off the top of my head, making up a core of say 50% fire clay, 20% slaked lime and 30 sawdust, in a trowelable mixture, about 20mm thick, for the combustion chamber and to let that dry and set - and then a wrapping of mineral wool around that, and then insert this all into a cast TIKI statue, </p><p>.</p><p>.I'd also be using a fairly low density concrete mix, with lots of sand, sawdust and lime, to make it breathable, to help the block dry out properly, instead of a HARD cement block that will shoot out craters (internally) of hot steam driven cement chunks.</p><p>.</p><p>A fairly soft, low density cement mix, with lots of lime and fireclay etc.</p>
<p>How large a bucket is this? I'm thinking about a 4 gallon? I have some kitty litter buckets from a friend that I would be ok to sacrifice to the Tiki god. (sorry, couldn't resist.) They could then go in the recycle bin. </p><p>I'm guessing a cast iron pan on top would work well. I have a lid for mine so could do some thin crust/flatbread pizza, quesadillas, etc.</p><p>Crushed glass instead of the rock would look cool on top. You can buy 'beach' glass at the craft store so it doesn't have sharp edges. </p><p>I also have a 'collection' of rocks from digging up the lawn to make a garden. That would be a fun way to use the prettier ones.</p>
You should offer The Volcano Goddess Pele, Mystic Pork. Just lay it down on your Highway escape route before it's covered in flowing Lava.
lol if there was a way to upvote your comment....i'd do it in a heartbeat.
<p>I have made wood fire hot enough to melt glass, and thin aluminum, soooo unless it is glass meant for this I would think not, BUT you could use it in other places while making this. </p><p>Also an issue is rock in general. At the very least.. heat the rocks you are going to use a ew times in hot fires. If the rock is porous and has water in it (river rock can be nasty, fatal even) if can do the steam expansion and shatter. I had a sliver go through a pants leg when I was a kid. And no water was spilled on the rock. </p>
<p>This is a nice project I will make on in the spring. I made mine with a metal 5 gallon food oil metal can. That thing can throw a 2 foot plume of flaming fun. </p>
<p>Hi. Really enjoyed reading about your project! I made a tiki burner myself </p><p>http://www.instructables.com/id/Outdoor-fire-place-or-Chimenea-from-ferrocement/ some years ago. Got into rocketstoves after that, pizza ovens and now Rumford fireplaces. Check them out, maybe you can come up with a funky design for these awesome and superior fireplaces. Cheers, Thijs</p>
Just wanted to say congratulations on being a finalists in the Concrete &amp; Casting Contest! This was a fantastic instructable love the materials you used and felt I could make this myself! Good luck! :)
Very funny character, is put on a flower bed at the cottage
LOVE this! Did you remove the top end cap? I would think the heat would melt the plastic if left in.
Yes, the end caps come out.
Rubbing the inside of the bucket with petroleum jelly (something I learned in sculpture classes) might have made it possible to remove the concrete without destroying the bucket. This doesn't always work, and sometimes breaking the suction destroys the mold anyway, but it's always worth a try.
Thanks for the tip. Sounds messy. I think the end caps made it so hard to remove.
I love the design of it!
Have you done any tests to see how hot it gets up to? This would be great fun to use to cook small bits of meat or fish on--sort of like a fondue only with fire!
Really love it! <br> <br>And it seems so easy with your instructions. <br> <br>Thanks for sharing it! =)
Thanks for the inspiration! Definitely on the want to do list!
Great idea!
Tiki tiki<br/>Ps I even have a comic series for tikis I'm tiki man the god of all tikis
The smoking head is the best! :))
That is so neat! I love how you can use it as a stove. I enjoyed the sketches.
This was my 1st instructable, glad you liked it. Peace.
Nice, and it was featured!
Very cool concept and execution.
