geodesic dome hubs

hi everyone i have been wanting to make a geodesic dome for a while now and i dont want to spend money ond conduiting which looks easy to do and all the angles associated with timber domes seem over complicated so i thought that pvc/ plastic pipe might be cheap enough though i find the hubs extremly expensive so i thought up a design that is in between almost all homemade hubs. the center of the hub is circulat like the pic and the bolts potrude at all apropriate angles then on the bolts is a rubber sleeve that snuggly fits into the inside diameter of the tube you are using then when you tighten the bolt the rubber is squished and pushes outwared on the tube so the hub stays on the tube just thinking that someone here might be able to improve the desighn and or make it. thanks for your ideas.
