Julia, This is wonderful. I'm inspired to make some cob after a cursory look about how to make it. Here in central Texas we have a clay rich soil.

Question. (or two)

Around your firebricks duraboard I notice you have some sort of masonry? Are those just concrete blocks? Also, what are you using to cement them together? I do see some sort of bonding material between the blocks.

I like how you later-on covered the entire J tube in Cobb. I hope to reproduce that since we have access to hundreds of thousands of pounds of clay rich dirt and sand.

Thank you for helping answer my questions!

Hmmm...Until someone with experience pitches in it looks to me like a stand is necessary to suspend the barrel containing the oven over the J tube.



I figured I could just build something out of wood... But how do I clean out the ash? I feel like Im trying to reinvent the wheel overhere.

I bought the plans and have been cutting into my steel drums and it is tremendously helpful to have step-by-step help, even with how to operate a grinder. It is Idiot proof.

But there are 4 MAJOR deficiencies that are NOT idiot proof and I'm stumped with how to solve the problem.

1. I don't have a clue about how to build the J-Tube. There is go guide with the DVD I bought and not even dimensions with the companion guide. On the site there are some details about building a J-tube, but it requires welding! I'm lucky enough to be able to operate a metal grinder. A welder is wayyyy outside my skillset. What do I do? Just stack up bricks or something? what dimensions?

2. The DVD and the companion guide tell me to use Duraboard. I have no idea where to source it. One place sells 1 sq. ft. pieces of something like it, for $30. Can I just use firebricks?

3. I barely know what cob is let alone how to make it. Is there some sort of high-temp concrete that I can buy from Homedepot or something?

4. How do I mount the oven on the J-tube? Do I build some sort of stand? How high?

I thought if I bought the DVD I'd be able to build a functional rocket oven. I can only build the oven, the J-tube is a mystery. Can anyone help please.

Is there  no-weld version of this?

I have just purchased the DVD streaming. How do I get the companion guide?

Edited: I just paid the $5
I love the video. Except

I don't understand how to build the J Tube. What are the materials? I have no idea from the video.

How do I stand up the oven on the J tube? Do I build a stand out of wood?  Won't it burn?
