Stanwood Needlecraft Large Metal Yarn/Fiber/Wool/String Ball Winder 10 oz This super high-quality winder is built to withstand heavy use. In comparison to competitors' models, our model has the following advantages: (1) We use special nylon material for cogwheels. They are super strong but make much less noise than the metal cogwheels, (2) Our model does not require tools to assemble, (3) Our frame is painted by electrostatic painting so the paint won't come off, (4) The edges of this machine are super smooth. It won't leave any marks on your table. This winder can handle about 10 oz. of yarn, which is 2.5 times of what our smaller winder does. It can be clamped onto a table up to 2 1/8" thick. It is best to be used with a swift yarn winder (Umbrella or Amish style, both available under Stanwood Needlecraft brand names). But you can easily replace a swift with other devices or just simply your arms. Effortlessly and flawlessly produce dozens of easy to manage center-pulled yarn balls. Our specific gears are designed to be both durable and flexible. Tough enough to handle high-speed winding, soft enough to ensure the gear noise is at an absolute minimum. Our yarn winder is constructed from 3-millimeter-thick steel with rust-resistant powder coating to ensure it will stay in place so you can organize your yarns quickly and safely. Trying to find a wrench to set up to wind is annoying, so we designed our winder to be set up without any hassle, so you can wind faster. CENTER-PULL YARN BALL, our yarn winder creates yarn balls with the string that can be pull from the center, making your knitting sessions convenient and neat. ULTRA HEAVY DUTY, our yarn winder is constructed from 3-millimeter-thick steel with rust-resistant powder coating to ensure it will stay in place so you can organize your yarns quickly and safely. REINFORCED NYLON GEAR, our specific gears are designed to be both durable and flexible.
