Assembling the new roof

I started to assemble the roof today. I created four 2.4m x 2.4m square frames , and laid them out on the floor. The structure is very weak, so to strengthen, I then cut four right angle triangles for each corner, four equilateral triangles to bridge the four frames together, and one diamond to link the centre points. These are all fixed with four to six screws to make sure the structure is robust. Because the total size is much bigger then the ceiling height, I can’t flip the roof over. This causes a problem because I wish to line the underside with seamless paper, however can’t get underneath to do so, as the roof must stay facing downwards so it can be picked up and floated onto the installation itself. To get around this issue, I propped up the roof in nine places with cut off block of wood, and ran a long piece of wood through the tube which the paper came on, which I then wedged behind two breeze blocks, so when I pulled the paper, it unraveled without moving. I pulled the paper out and underneath the structure, moving the wooden blocks accordingly so the structure still floated over the surface. When the paper was in place, slightly overlapping the halfway point due to being 2.8m across, I made sure the paper was flat, then folded the edges around to the top of the frame. I stapled thoroughly along the edges, and secured the centre beams with masking tape. The next half will be attached Tuesday, followed by placement and the dome mirror.
