Evil Mad Scientist offers an easy hack for using industrial-sized spools on standard home sewing machines. Using an old computer fan and a short length of copper tubing, they created a spool spinner that can adapter.
They say, “In practice, the fan bearing turns freely enough that the sewing machine can spin the spool as needed, but not so freely that it starts to turn and then unwinds the whole spool, so it works quite well.”
