Schacht Bulky Bobbin for faster whorls in double drive

thingiverse

This bobbin is designed for use with Schacht wheels that can take advantage of double drive capabilities, as well as for spinners who want to spin and ply large amounts of finer yarn using the fast and high speed whorls. The ends are interchangeable, simply screwing onto the core, offering versatility in terms of spindle usage. The fast bobbin end pairs seamlessly with the fast whorl, while the hi-speed end is perfectly matched for use with the high speed whorl, enabling efficient double drive plying. Additionally, I've included a plain end without a whorl but featuring a groove for use with tensioned Lazy Kates that can be placed on the orifice end of the bobbin if desired. To further expand spinning options, there are also orifice reducers available in 5 mm, 10 mm, and 15 mm sizes, accommodating spinners who aim to produce finer yarns.
