Geodome Project

  The completed structure  So.....In the words of Talking Heads....How did I get here. From earlier posts you will have seen the assembly of the polythene cover unit cells of Hexagons, Pentagons and 1/2 Hexagons......that allow the build to be easier to visualise and ultimately build correctly. Using the UV resistant mega strong tape and the gadget below (see earlier post) start connecting the unit cells into bigger fragments. (the gadget will take the strain of when trying to form a 3D structure from flat sheets). Its easy to get lost so I'd recommend joining 5 pairs of 2 hexagon cells as the basic 5 vertical stripes that you have to joing together via intervening pentagons. The repetition of this operation will hopefully result in less (0 errors) Gadget developed to join flat sheets to form a 3D cell. Once the whole structure is completed ....wait for a dry, windless day and go for it. I was assisted by my daughter who kept tension on 2 ropes straddling the top of the geodome whi

Well ...at long last the weather has improved, the mists of apathy have subsided and whilst covid19 still has a stranglehold on the world....Ive concentrated on what's really important.....The Geodome. Whilst the skeleton remains uncovered (waiting for a dry windless day!) ,it in itself is a personal triumph after all these months of trying to get everything right.    From the outside the view is more appealing and quite the feat , built single handed due to covid19 restrictions. How? Well a quick glance at the following video will reveal all. In summary, the structure is flexible and wobbly until it is complete and all joints are tightened fully. This is both forgiving in terms of breakage etc but aggrivating in terms of handling and manipulation. The task is to build a layer under the preceding layer by raising the structure on concrete blocks (4" at a time....at a number of points on the circumeference to minimise the stresses and strains within the framework.
