I'm having problems with the split ring staying separated too. It's also very difficult to split the ring then work it around the swivel and the spinner blade. I'm working with the pony head jig, size #0 split ring(from Do-It Molds) with the small Texas Tackle split ring pliers. Do ya'll use a fly tying vise or just hold the stuff in your hands? Will a better quality split ring be easier to work with or just not bend easily? I purchased one of the Ott magnifying lights and that helps a lot as far as seeing this tiny stuff but it's another thing to hold on to it and put it together. I hope you don't mind that I resurrect this thread. I appreciate any tips. Thanks.
