Simple wire stretching exercises were performed. The wire is approximated to have to be well past its elastic limit bearing 50 g weight. A thumb screw threading two washers going into a threaded stand-off (long nut) provided a nice 4.8 g weight that can clamp wire. So a wire loop is created by clamping the ends of a wire segment between the washers by tightening the thumb screw.
