I am at the beginning of making another rocket oven which has a longer oven inside. The original size that was introduced in Rocket Ovens DVD
was abit short for our summer camps. Now i will make one that has 60cm (24") long compartment so that i can bake three pans that are 50cm (20") long.
Since the volume to be heated is larger and since the volume of baked food is larger i am thinking of coupling it to a larger J-tube system, probably 175mm (7"). Thoughts about that are welcome.
Yesterday i opened two drums. In the next days i will start making it..
Oh, some photos of my previous oven can be seen here:
And final appearance with metal sheet cover:
Have a nice day,
