Dome frame question
I just discovered you domes. As one who is leery of introducing any nore
pvc into the envioronment, are there any other tubing materials (and
joiners) that would work? I assume you have investigated this.
You can use bamboo, branches, wood strips, aluminum tubing, fiberglass (solid rod or tubing) or any material with sufficient stiffness to flexibility relationship. To get the right stiffness compare to one of our PVC poles of the same length. You will also need to make connectors that your replacement poles fit into with about 1/4″ of slack and with the same bending strength as your poles. Connectors are 6″ with a hole in the middle (two per pole intersection with 12 for the ground level.
