Can I get the TL;DR version? I want to know if I can get the plans for a rocket oven like yours. What caught my ear was the phrase "fifteen-hundred degrees." I'm thinking that this, or a variant, may actually make a good forge.
I have a 4-dvd set called "Wood Burning Stoves 2.0" - on DVD4 we make something to compete with a turkey cooker. And then a blacksmith stops by and says "I think that would work as a forge. So, in the video is the turkey cooker competition (rocket wins) and then about 20 minutes of using it like a forge.
