Building my first rocket oven. Need your help to doublecheck measurements of rocket unit.

Hello my fellow rocketeers!
This is my first post on this forum just 5 minutes after registration. Have been a lurker for a while though...

I have built smaller portable rocket stoves before with success. but now I need and want to build one with a pizza oven.

I did a simple mockup of the plans. Please give me your thoughts! They would make me happy, and hopefully a better oven.
The most important measurements should be there...

It's the widths, lengths and that stuff I need you thoughts on.

Aside from what is in the picture some kind of diffuser plate and other details like a peter channel and stuff will be used as well. I will probalby also build a small insulated door at the the wood-end of the burn tunnel, coming in from the side. For easy cleaning and experiments with air intake.


Thanks from Johannes, working at the guesthouse DoneRight in Cambodia.

The results will of course be posted here. Sharing!

Hey Johannes, how did it go? I'm about to build something very similar. What did you mean 'peter channel'?

The peter channel or p-channel is a slot that delivers fresh air to the top of the burn tunnel in a J-tube, introducing turbulence and mixing oxygen into the hot gases. Together with a "tripwire" which is a small ridge in the top of the burn tunnel, it increases combustion efficiency. Search for those terms for many good technical descriptions and illustrations of them.
