This WooLee Winder will fit the Ashford Electric Spinner 1, which is the triangle-shaped spinner. The WooLee Winder consists of the flyer and one bobbin and uses the whorls from Ashford so the ratios remain the same as with your stock flyer.
Note: The difference between the model 1 and 2 is how the flyer connects to the motor.
Model 1 has a U-shaped cut in the shaft. The model 2 has a flat spot on the flyer shaft.
