Yes, a meat grinder followed me home. Been looking and can't find anything about the universal #73. How do you clean and maintain this beast? (aside from opening it...) What lubricants are safe and helpful in the long run? Which blade chops what? I have looked up the instruction manual, and found nothing yet. Point me in the right direction. At work I like motors and am very grateful for electricity, but in the kitchen, I like a good work out- am sure the other mechanical grinders are awesome, but am interested (at least for now) in some of the non-electric appliances.
