Well, I picked up some plastic bolts and wing nuts from Home Depot and they seem to hold the two halves together fairly well, but I now have additional challenges ... I've been trying this, but I find the chocolate sets pretty quickly and I don't get a very even coverage of the shells (sometimes it sets so quickly that it doesn't cover the entire shell). Even vigourously shaking the molds doesn't seem to move the chocolate. I'm considering filling the two halves separately, dumping the excess, and trying to put the halves together before they set (and hopefully without losing too much chocolate from the top half). Does anybody have any other advice on a good way to ensure the mold produces nice shells? Cheers, Chris
