Schacht's hand bobbin winders are available in single-end and double-end
models. The single-end winder has a tapered shaft that will accommodate
bobbins up to 6″ long. The double-end winders can be used for bobbins, pirns, and large-flanged spools up to 9″ long and 5-1/2″ in diameter. A clamp incorporated into the base means you’ll never have to hunt around for a “C” clamp again. They are belt-driven with self-lubricating bronze bearings.
Shaft too large in diameter for cardboard quills and Ashford plastic bobbins.
Bobbin is not included.
