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).

• 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

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.

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.

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.

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.

Hi. Really enjoyed reading about your project! I made a tiki burner myself 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

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.

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!
