We recently had a customer write in with some questions about powering their Country Living Hand Grain Mill with their existing KitchenAid. Other folks have made it work, so it is definitely possible. Although we don’t carry the parts, we thought this would be useful to spark come creative ideas. For measurements, the Country Living shaft is 5/8″ in diameter. There is a small key that is inserted to ensure traction, and at that point, the shaft plus the key measure 0.69″. The key itself is 3/16″ along each side, and 1 1/4″ long. Thus, with those measurements, you should be able to find the write adapters. Hope that helps!
