That sounds like an interesting project. I know I have seen the
formulas for calculating geodesic strut lengths in all those books
that were published in the late 60's and early 70's. I am sure there
must be a wealth of information out there.
You may find this article helpful:
http://sci-toys.com/scitoys/scitoys/mathematics/dome/dome.html
Which describes building domes out of simple materials. The drinking
straw example, I thought may be relevant to what you wanted to do,
since the diameter of the straws is close to the 1/4 diameter tubing.
As an aside, I am interested in people doing mathematics and
sculptural - architectural projects. I am an metal and wood tinkerer
who is interested in finding design inspiration through mathematics.

Primary material would be the small sized (about 1/4 inch) copper
water pipe
that comes pre-coiled at about 36 inch diameter; the coil diameter
would be
used to establish the basic ball diameter and I will set up a jig
to fairly
accurately cut the pieces; which will (with flattened ends) then be
pin
jointed.
Assuming a coil/ball diameter of 100 I need to find the chord and arc
lengths for the pentagons/hexagons.
I have been trying to extract the information from the Bucky Demo
script but
am not having much success ... help would be appreciated.
Thank you
David
