My original question still stands - does anyone have a solution for me?

Have you tried a Technic 3 blade rotor?  It's not *quite* what you are • trying
to build, but I think it should be workable.

A 3 blade rotor will give the same angle geometry but I don't beleive it
is what James is asking. I believe he is asking how to anchor something
to the top of this assembly that is connected to all three legs.
Geometrically, there is no arrangement that will work, as there is no
right triangle with integral side lengths that has a 60 degree angle.
The length of the hypotenuse is not a rational number if the smaller
side is 1.

Therefore to fix a rectangular plate at the top of this you will need to
use some sliding component somewhere.

:-/  That's pretty much the same conclusion I came to. Unfortunately, I can't
get enough stability from that with the current design. <sigh>

Back to the drawing board <grumble grumble bitch bitch>  I _liked_ that design
too. Maybe I'll sooth my ego by putting up a picture on my site.  ;)

Please do that.  I can't seem to visualize it with just text and ascii
descriptions.  With an actual picture, or maybe an ldraw rendering,
someone may be able to suggest something useful.
