<p>Hi I want to make a geodesic sphere fom bamboo as its free no cost, strong and light , i plan to carry it on a bike trailer, it will serve as a bedroom for me as i will put a bed in the centre. storage underneath. It can hang in the trees too. </p><p>I need to make it big as possible but not bigger than a road so this is perfect size</p><p>To join the bamboo together I have researched methods and cut off pieces of hose pipe seem the best idea. I will not be able to make bends in the bamboo</p><p>Do you think it will work if I use your measurements of lengh and then use as the hubs , hose pipe pieces bolted together, to connect. Im trying to make this all for virtually no cost, so i can not download the instructions as it costs, but I should be able to work it out from the measurements. </p><p>Any help advice happily recieved, merci ,</p><p>my email is thestageship.com, </p>
Might have just figured out the answer: did it just come out that way because all the struts are the same length?
The struts are 2 different length.<br>Dimensions for the real sphere:<br>To build a sphere with a radius of 4.25 feet requires:<br>70 Struts 2.63 feet each bend angle 18o<br>60 Struts 2.32 feet each bend angle 16o<br>52 Bolts, 52 Nuts, &amp; 104 Washers :)<br><br>
Actually it comes out that way because the struts are DIFFERENT sizes. its deliberate to make the structure stronger and stop the vertices popping inwards under stress.<br><br>www.Desert domes.com will show you how to make this.
Is there a structural reason why each pentagon is &quot;domed&quot; with the center joint higher than the sides?
Yes, for keep the sphericity. If they are flat, the object don't look like a sphere.
Very nice!
Thank You :) and less than $200 :)
