The Schacht Bulky Flyer Package adds bulky-yarn and plying capability to any current Schacht spinning wheel. The standard flyer's orifice and bobbin can't accommodate chunky yarn, multi-ply combinations, or art yarn at scale. The Bulky Flyer's wider 7/8 In orifice and large-capacity Bulky Bobbin handle yarn that would jam or overflow the regular flyer.This is the wheel-specific package: select your wheel from the variants. Each variant ships with the Bulky Flyer assembly, one Bulky Bobbin, and the wheel-specific Bulky Front Maiden and bearing. Made in Boulder, Colorado.What's in the package Bulky Flyer assembly with sliding hooks for even bobbin filling Large round guide hooks for chunky and art yarn One Bulky Bobbin (about 8 oz capacity) Wheel-specific Bulky Front Maiden and bearing Whorl ratios are unchangedSwitching to the Bulky Flyer does not change your whorl ratios. The same whorl set works at the same ratios whether you're spinning singles on the standard flyer or chunky yarn on the bulky flyer. No range is lost when adding bulky capability.Bobbins on the bulky flyer shaftStandard, Travel, and High Speed bobbins all fit on the Bulky Flyer shaft. A spinner who owns the Bulky Flyer Package can use existing bobbins without swapping flyers. Only the Bulky Bobbin requires the bulky flyer; it will not fit on a standard flyer.Choose your wheel Sidekick, Ladybug, or Flatiron: one package each, no further selection needed Matchless: requires identifying the front-maiden style.
