The most important part of the dome is the base ring. This needs to be perfectly circular and strong enough to support the roof. This web site describes the process of making a base ring from plywood using a router.
I tried using a couple of CAD programs to design the dome but found them to be too complicated for me. I ended up using graph paper and a compass (guess I'm getting old!). The frame is made of ½ inch ply and was put together in 6 bits, as my garage was not big enough to house the dome complete. The frame was skinned with wire mesh before glass matt and resin were added. I did the fiber glassing in January so had a few problems keeping things warm enough to go off. Also the wet matting would slide off the frame if the quadrants were not laid on their side.
