This WooLee Winder has a 3/8 orifice making it compatible with an Ashford wheel with the standard flyer bushings. It will fit the Kiwi, Traditional double belt, the Traveler double belt, and the Elizabeth 1 and 2.  It uses the whorls from Ashford so the ratios remain the same as with your stock flyer.  The WooLee Winder consists of the flyer and one bobbin.
