This 3 speed bobbin is clear lacquered to match the finish of the S10, S10DT and S51, S51DT wheels but will fit the S17, S15 and S75 as well. The bobbin has a sheave with three settings on one end to obtain three different spinning speeds. The ratio's for these wheels are controlled by the bobbin and are: 5.5:1 for slow spinning and heavy yarn; 7.5:1 for medium yarn; and, 10.5:1 for fast spinning and fine yarn.
Bobbins will hold approximately 180-250g of yarn - a very large capacity.
