Once the frames are part assembled and covered you are rady to start building the dome. Knock a stake into the ground (or fix a point on hard surfaces) to mark the centre of your dome, mark a circle 2.4 meters radius.
Place the base sections on the ground in the correct order (see base assembly diagram) starting with an “A” section where the door will be.
There should be 14 base section beams, 4 that are level, 5 with a slope to the left and 5 with a slope to the right. All the base beams have a chamfer on the top edge that slopes towards the outside of the dome.
Tips: Use an ''A'' section base beam where the door will be, mark the ground and remove it when you need to for the last ''A'' section in the base.
