Iain, unfortunately Hexagone had some imperfect geometry in it. I ended up
using the studless single angle beams at the corners. They are not exactly
120 degrees (my protractor says about 125) so I had to force them into that
shape a bit. The reason I stuck with this method is that it was so much more
rigid and compact than any of the other ideas. I started the thread Ross is
referring to when I first started building hexagone :) Most of the links to
the ideas people offered are broken now, but this one is still good:

If you have a lot of these hinge plates then you can build a hexagon with
perfect geometry.
The nice thing about a hexagon is that the distance between two opposite
points is an exact number. This makes it easy to attach the hexagon to a
turntable:

The other spokes attached to the turntable were the result of trial and
error. They seemed to fit nicely though.
