No thrust on the walls, either?

Is this like building something twisted to its furthest extent, there for it can't go any more? Take common rafters for example, but they exert thrust on the walls. If you release them from their accepted form by twisting them into this new approach, there you have it? Could torque be involved? Where does the energy go?

Don, was it a complete wrap of the wire and twisted off? Did it relax under your load, stretch to tighten up, just a bit?

I may have to give this a try.
