Permaculture Our Urban Design Part 8 - Rocket Oven Pt2

Part 2 of 2 in the construction of a rocket stove cob oven. This is an attempt to replicate an oven put together by Jon and Flip in a video here on YouTube entitled "Rocket Oven.mov"... link http://youtu.be/uR-LqOquLZA.

@mrsadoisland Message me if you post clips of your block in Japan... I'd be keen to see how things are done there...

Hi there, thanks for your excellent high quality video! You inspired me to build something similar too. The only thing that makes me doubt is that you are reaching only such low temperatures. For pizza's, I need about 500'C. Is it maybe that your rocket stove is too small to heat up the whole mass? By the way, I am considering to use rebars and chicken wire to reinforce the construction, does that sound smart or stupid? Thanks again! It was a pleasure to watch!

@xWintermutex Hey there... Ta... Your right, for us the temperatures are good but more similar to a normal oven... lately we are growing accustom to cooking at 200 deg C because the oven seems to hover there with the lest amount of monitoring… The original posters… DateFarmer have had theirs up to 1250 deg F! Either way, so long as you are able to make the stove removable it can be easily experimented upon… It also seems logical that a larger rocket stove should produce more heat… Chris

@xWintermutex Secondly...If you build the cob as thick as we did I don’t believe the dome itself needs reo…But I would strongly recommend reinforcing the doorway in some fashion…We used 50mm by 3mm flat bar, it was pretty cheap and really easy to work with…We originally put single pieces of 12mm reobar above the doorway but with out a solid reference point they gave little strength…Our flat bar on the other hand had its foundation in the preset cob base and worked like a treat…Chris

Forgive me but I believe there is linseed oil that is placed in cob to make it water sealed.its a all-natural alternative to other sealants and such.

[MrChrisTowerton]

@spiritualinsight Hey there... I've read that linseed can be painted onto the cob, we did consider this but we also wanted to try lime render...Maybe we could have sealed the cob first, then rendered it? But I guess the linseed would need to be reapplied some time in the future? Whereas the driveway sealant will probably last two years and can be reapplied directly to the render.... Any other location and we would have just built a roof over it....:-) Chris

@AOHCalgary Ta... The barrel was made of plastic. We cut it with an angle grinder in two locations, one each side of the door aperture... Some sand was then dug out leaving the rest of the drum easy to removed...As stated in the clip though, the doorway needed to be quickly supported, as it began to sag straight way... Hope this helps... Chris

Awesome Video!

We need to move our old Cob oven and this gives me a great idea for our new outdoor kitchen. My question is how did you get the metal drum out when you were ready to remove the sand?

cheers
