Want to tell you about some domes we have made. I figure we may need them for personal shelter and to store some of our possessions in. With clear plastic they could be used for growing plants, of course.
Both are made of schedule 40 PVC in three quarter inch size. Hubs were a problem at first. Then someone suggested using lids from 5 gallon pails. Someone figured you could wire the struts to the lids using twist wires. I bought a little tool at the hardware store, a hook that swivels on a handle. It is used to secure rebar before concrete is poured. The lids are very strong and flex to give you the curve the domes need. Also, the lip at the edge of the lids gives you an angle too.
The second dome uses sections of 4 inch diameter PVC pipe for hubs. Holes are drilled for the struts using a 1 and 1/8 inch spade bit. Each end of a strut has two holes drilled through it and galvanized nails are pushed through the holes, one inside and one outside the hub. You can put this design together without any tools. Seems like it would be loose, but the curved form of the dome creates tension and makes the parts lock up.
What do you think G? Could these little shelters be used by the New American Peasant?
If anyone is interested I can supply details.
