The Pollywog Orifice Riser raises your SpinOlution Pollywog's orifice height by 3 In, useful for taller spinners and for matching a specific chair-and-wheel setup. The kit includes the riser block and the Extended Drive Band, the longer band needed to span the new drive path. How It Works The riser mounts to the existing Pollywog frame in place of the standard flyer mount, taking the orifice from 19.25 In to 22.25 In. Standard hand tools are all you need. The included Extended Drive Band replaces the Standard Band so the longer drive path tracks correctly. If you ever need a replacement, the Extended Band is also sold individually as a variant of the Pollywog Drive Bands product. Compatibility Designed for the SpinOlution Pollywog spinning wheel only. The Orifice Riser is not recommended in combination with the Pollywog Accelerator; the two accessories alter the geometry differently and don't stack cleanly. Specifications Adds 3 In to orifice height (19.25 In standard becomes 22.25 In with riser) Includes Extended Drive Band (replaces the Standard Band while the riser is installed) Material: Baltic birch Pollywog-specific (does not fit other SpinOlution wheels) About SpinOlution SpinOlution spinning wheels and accessories are designed and crafted in the USA.
