Types of Wheel Drives
Single Drive Wheels
This type of wheel has one drive band around the flyer wheel and the flyer whorl. There is usually a separate brake on the bobbin using an adjustable brake band or a tension wire (The Scotch Tension brake system), for the purpose of regulating the speed by which the yarn winds onto the bobbin.When spinning, a brake is used to hold the bobbin still while the flyer continues to rotate. Increased tension on the brake will cause the yarn to pull from your hands and to wind quickly onto the bobbin. Single drive wheels are the best choice for beginning handspinners. The Scotch Tension brake system is easier for beginners to operate and understand. The tension on the flyer and bobbin can be set at separate speeds, which provides numerous adjustment levels for the beginner. You will be able to spin a variety of yarn types; soft, lumpy, novelty, etc.
Double Drive Wheels
This type of wheel has the flyer whorl and bobbin next to one another on the same side of the spindle. The drive band is doubled and forms a figure eight that loops onto both the bobbin and the flyer whorl. The spinner decides where the drive band is placed on the whorl depending upon the type of yarn to be spun. When spinning, both the flyer and the bobbin are rotated by the drive band. The bobbin whorl is smaller in diameter than the flyer whorl, therefore, it will spin faster than the flyer if there is no brake being used. Because of the high degree of twisting efficiency, beginners who have a problem with overtwisting the yarn, will find the double drive wheel difficult to use at first.
Bobbin Lead Wheels
The Louet spinning wheel is a good example of a bobbin lead wheel. The whorls are located on the bobbin instead of the flyer. The drive band goes around the drive wheel and one of the bobbin whorls. There is a single leather brake band that lays across the end of the flyer. It has an adjustable sleeve that can be tighten or loosened, to control the speed of the flyer. Bobbin lead wheels are a good choice for a beginner spinner. The tension is easier to control, and there is more traction created by the force of the drive wheel, which allows heavier, bulky yarns to wind onto the bobbin.
