I am interested in trying to make some thick/bushy dubbing brushes like the EP crustaceous or shrimp brushes for tying saltwater flies. I have a dubbing spinning block and know how to do the fine ones with regular dubbing and wire for freshwater nymphs. I have tried using about 3/4" segments of poly yarn instead of dubbing but the wire will not twist very tightly and trap the yarn before the wire breaks. Does anyone know how to make this type of heavy/bushy dubbing brush? Any help is appreciated.
