geodesic hub system

these hubs can let you construct a geodesic dome with 1/2 inch rod such as pvc or wood etc. for the struts.

this works because the hubs will bend allowing the end to match up.

with the 3p hubs you will only need 1 size strut.

with the 5p and 6p hubs you will need 3 different strut lengths.

in addition you can make any frequency dome, 2v, 4v,5v,etc.

to get the strut legth you will need to use the geodesic dome strut length formula which you can find online. try here: http://www.byexample.net/library/calculators/geodesic_dome_calculator/index.html
