Just received my crank and stein 2s (4 inch rollers) I am going to be building my hopper when I get off work today. I got my general design. My question is, how big should the hole be that feeds the grain to the mill? My friends mill looks to be about 8 inch rollers but there is only a 2 inch opening. Is that fine? Or can I get more grain crushed with a bigger hole? Or can that jam up my mill rollers?
