The Pollywog wheel can be ordered with an accelerator head which raises the orifice height and gives you 7 more ratios to play with!
This removable piece attaches between the base and the head of your Pollywog wheel, and does two things. It raises the height of the orifice of your Pollywog and gives you additional speeds for spinning finer weight yarns. Adding this accessory to the Pollywog is perfect for filling the 4 oz bobbins with finer yarns.
The Pollywog has 3 speeds without the accelerator: 1:10, 1:4.5, 1:2.5
With the accelerator, there are a total of 10 speeds: 1:22, 1:17, 1:15, 1:13, 1:11, 1:10, 1:8, 1:7, 1:6, 1:5
