*The extra slow whorl cannot be used on the Sidekick wheel.
**A high speed bobbin is required for spinning with high speed and super high speed whorls in double drive. (High speed bobbins are not required for Scotch tension mode.)
Whorls are available in maple or cherry wood to match your wheel.
Whorls allow the bobbin to turn at a particular speed in relation to the revolutions of the wheel’s drive band. This relationship is given as a spinning ratio. A slower (bigger) whorl will slow down the bobbin and produce a yarn with less twist; a faster (smaller) whorl will speed up the bobbin and produce a yarn with more twist. Each Schacht whorl has a bigger and a smaller ridge into which the drive band can sit, so each whorl gives two possible spinning ratios. The ratios are listed with the individual wheels.
