Well,here's an odd one. I was assembling my new Barley Crusher Grain mill & looked at the instructions. Lubing the bushings with a couple drops of veggie oil twice a year sounds understandable. But why in the world would they say,the first time it's used,or after the mill has set for an extended period,to run a half pound of grain through it & discard,brush off rollers,& continue with your grain bill?? Isn't this something brushing the rollers clean should take care of?
