hey there.

$1 a brick is pretty awesome. My acquaintance is wanting to build a BBQ pit and bricks make the thing REALLY expensive.

There is a technique, or family of techniques, for making cob/adobe strong enough for the fire box of this thing. I am studying it myself (and trying to raise a little money for the cause).

the techniques are related to or are a member of geopolymerization. The only “exotic” component is sodium hydroxide, which can reasonably be made from natural ingredients itself, depending on the geology of the area.

(contact info for me on that site)

I am trying to raise money here: http://www.kickstarter.com/projects/410996349/making-geopolymer-technology-accessible

thanks!

The pipe is embedded in the cob, so there shouldn’t really be any leaks… as for creosote, the stove is very clean burning, so there shouldn’t be much build-up. But I should be able to clean out the stove through the t-joints when I do need to do that.

Not to be paranoid but, what about creosote? And, what about leaks in the joints.

Jason: I’ve got three t-joints in the flue so that I can access the innards to clean the pipe. One is at the very beginning of the pipe, and the other two are at each 180 degree turn. Hopefully this will be sufficient to get in there and clean.

Hello, I had a question about cleaning the flue. How do you clean it if it’s making twists and turns for warming benches and such? Or maybe I’m not understanding how the bench was warmed in the video?
