I've been wanting to build a small geodesic dome
out of some trashpicked leaky hose. Up until today, it was mostly going to be just for fun, so I hadn't been putting much effort into figuring out how to do it, but then when I got invited to help out with a community garden in my neighborhood, I realized that the dome would be a perfect trellis for the climbing plants, while offering a bit of protection from wayward bicycles and other larger creatures wandering around the area.
The main idea is to cut the hose into about 1 foot long segments, and assemble all the segments into a 2/3 Bucky dome. But, I'm not quite sure about how to do the "assembling" part.
So what I'm looking for from you folks are some possibilities for connecting several hose segments to each other. (Up to six segments of hose have to come together at the points!) The hose is pretty thick, but can definitely be cut with scissors and drilled with a drill. I don't really have any money, so I kind of need to use something that I can trashpick or recycle. I originally thought of running strips of bicycle tube elastic through the hose and tying it, but it doesn't give enough structural support to hold something as heavy as a bunch of zucchini. If worse comes to worst, I'll beg, borrow, or steal some really long bolts and nuts, and just hope for the best, and hope that the thickness doesn't cause too much of a problem.
It seems like there should be something obvious that I could do, though, but I'm just not imagining it. Any ideas?
