Knitting with a KitchenAid stand mixer:

Faced with winding 30 some skeins of Jamieson & Smith 2 ply jumper weight into center pull skeins, I decided to search the web for an easier method than a swift and a hand cranked ball winder. Not wanting to pay for an electric winder, DH and I figured out there had to be a way to attach a small motor to the ball winder. NOT! So what other small motors were in the house that allowed a circular wind motion? Why an electric mixer of course!!! Having had surgery for carpal tunnel once, I prefer to save the hand motions for knitting rather than winding.

Google search brought up these sites from knitters who already had the idea:

So out came the Kitchen Aid mixer with the dough hook. I found that cutting a 4" square of lightweight cardboard, taping it into a tube and slipping it over the dough hook worked perfectly. There were no empty cardboard cylinders in the house at the moment but I will save some paper towel cardboard. I think they would be even better than thinner cardboard tubes.
The first couple of skeins were a bit comical as they looked more like children's tops than balled yarn but what the heck. It saved a lot of hand winding. Kitchen Aid stand mixer run on motor speed 6 balled a skein of yarn in about 45 seconds.

Lesson learned - Google is your friend.
