Hey Jack, what was the result with your clay? Did it pop through the wire, or is there anything else you can add as to why you think it's not quite right? It won't work properly if your wire is very stiff and stronger than the clay. There is a way around that problem where you build some thick bones with sculpey (that you've baked) first. It spreads the pressure on the arms/legs out so the clay doesn't squish as much. You need to round the sculpey into the jointed area so it can bend after you bake it. But that should help in a huge way if you still have problems after melting the clay to the wire.
