What do you use in the dome for support?
What do you use to support the dome across the top and sides to keep it from falling in?
If you used solid bricks on Steve`s dome, do you have the molds you used? Can you tell us how and what you used to make them and the design of the molds? What angles did you use to make the form a dome?
A properly built dome is self supporting.
I'm planning a build using airforms as the support in the very near future. You can follow my progress on YouTube.
