This WooLee Winder will fit the Fricke E-Spinner and all the S-160 models and has a 3/8” round orifice. It uses the whorls from Fricke so the ratios remain the same as with your stock flyer. The WooLee Winder consists of the flyer and one bobbin.
Please Note: The bobbin ends for the Woolee Winder are made of maple hardwood and are therefore NOT boilable. They have the same relative capacity as the Fricke bobbins.
