Coby and the re-construction crew tested different methods for bending the poles into perfect arches. First, they placed two poles in the foundation and attempted to bend them toward eachother, tying the tops of the saplings together.
However, this method did not create the desired arch shape for the poles, making the arches too narrow and pointed for the dome-like frame.
Ruling out the first method, Coby and the team went back to the drawing board. They then decided to arch the poles before erecting them by bending them in a nesting jig.
Each arch consists of two poles meeting at the top.
