This is my setup to help minimize the tug or strain on fine single strands of yarn while transferring them from a spinning wheel bobbin to a secondary bobbin for plying. The spinning wheel’s bobbin is placed on a kate (bottom left). The singles yarn is brought up and around a bar or rod (in this case the breast beam of my loom) and then wound onto a secondary bobbin. The secondary bobbin on the wheel is sitting on a spinning wheel bobbin winder. Spinning wheel bobbin winders are made to fit onto the flyer shaft or into the orifice. I use a similar setup to wind fine yarns onto bobbins for weaving. Instead of a kate, the fine yarn is wound from a cone positioned on the floor below the breast beam.
