Small Diameter Spindle
The Small Diameter Spindle (SDS) is an optional spindle for the ball winder. It is used to make a ball with a smaller center hole and as a result, a smaller ball in general. Most often used by people who make yarn kits for resale. All ball winders manufactured from around 2009 or so included the adjustable arm and post systems. However, units prior to that may not have included either the newer arm, post, or know. Most people buying this spindle DO NOT need these options. Contact us if you need help.
