Spinner's weasel


Spinner's weasel or clock reel is a mechanical yarn-measuring device consisting of a spoked wheel with gears attached to a pointer on a marked face and an internal mechanism which makes a "pop" sound after the desired length of yarn is measured. The pointer allows the spinner to see how close she/he is to reaching a skein. The weasel's gear ratio is usually 40 to 1, and the circumference of the reel is usually two yards, thus producing an 80-yard skein when the weasel pops.
spinner Charlene Parker demonstrates how to transfer thread or yard from a spinning wheel to a spinner's weasel.
Some reels or skein winders are made without the gear mechanism. They perform the same function, but without the "clock" or pop to aid the spinner in keeping track of the length of thread or yarn produced. A niddy noddy is an even simpler version.
The clock reel is a possible source for the word "weasel" in the nursery rhyme Pop Goes the Weasel.
