AHA! Another gadgeteer trying to re-invent the wheel, eh? ;-)

I can't see much wrong with the idea, although I think it would be kind
of cumbersome. You'd probably want it on a turntable (lazy susan bearing
thingy) since you'll have to tighten each rod a little at a time, evenly
all around. The ends of the rods may want to put a twisting force on the
segments as the pressure is increased, but a clamp disk on top will help
deal with that. Instead of flat ends on the rods, I'd grind them with a
rounded point or maybe just slightly convex would be good enough.
You'll need to somehow keep that clamp disk from being glued to the
segment ring--wax it, or?
Shouldn't take more than a couple hours to slap together, I say go ahead
and try it. But there are other ways, less cumbersome--many segmented
turners use band clamps, large hose clamps, or rope tournequets. If your
segment angles are right on, that kind of circumferential pressure will
do just fine. You may still need a clamp plate, but will only have one
screw or twister-stick to tighten instead of 12.
