This model is custom made under the brand name of "Stanwood Needlecraft". The quality of this machine is superior. It is heavy duty and built to last. Comparing to other 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 metal cogwheels. (2) Our model does not require tools to assemble. (3) Our frame is painted by electrostatic paiting so paint won't come off. (4) The edges of this machine are super smooth. It won't leave any marks on your table. We are very proud to finally offer this large model. It can handle about 10 oz of yarn, which is 2.5 times of what our smaller winder does. The winder can be clamped onto a table up to 2 1/8" thick. 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. Tough enough to handle high-speed winding, soft enough to ensure the gear noise is at an absolute minimum. 10 OUNCE CAPACITY, our winder can handle more than 2 times the yarn a conventional winder can handle, which can reduce your workload by half. TOOL-LESS SETUP, 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.
