I arrived yesterday to find the grain mill was not working. There is a hand mill that is tough to use for one person, so mill your grains at Beer Camp/Brew n Grow before your brew day. I'm not sure what is wrong with it.
Quick guide to use the hand mill. Attach the drill to the small extension on the right side. Attach it tight. Adjust the crush level on left (it should be ok, but double check it), set the mill on top of a bucket, get the drill going, and pour your grains in at a slow steady rate. It's a pain if you're alone, but it works. Thanks Matt for helping me figure this out last night!
