Gulf,

I wished I would have thought of that. I did mine with rebar and wire and it was a bitch. Yours is incredibly symetrical...

Thanks Les,
In all of my experince with building (born as an endentured servant into a construction family ), I have been taught to rely on measurements, levels, strings, speed poles, templates (the list goes on). I did not trust my "young eyes" so I definately don't trust this old pair that I have now .

The chicken wire seems to be to hold the blanket in place. If you are using vermacrete as insulation for the dome you can skip the chicken wire.

I probably, could have saved that step (and $) for the render . I am planning to install a layer of stucco wire in the render over the vcrete. I will be laying 1/2 concrete splits over this to finish.

Neil,

I used the wire over the rebar to form the dome. I slopped vermiculite / portland in between the wire and the blanket.

Most just shape the vcrete by eye and do great work. Some have used templates. I can't swear that it is easier to use a template but here are some pics of mine.

I would like to hear some ideas for the easiest way to shape a vermiculite concrete dome over my modular oven. I have blanket insulation and want to finish it with a stucco dome, from my reading, the simplest way to do this would be to shape vermiculite concrete over the top. I have seen several different people make rebar armatures for their oven and place the concrete on the that, I have also heard that all you need is the vermiculite concrete to shape the dome. I am worried about maintaining a decent looking dome shape with this approach.

I know many have done concrete vermiculite domes but I am having trouble finding good builds and photos from my searching.
