We have the Family Grain Mill as well, when we purchased the motorized version, the hand crank base came with it at no charge. We got it from
Pleasant Hill Grain. It works very well both motorized and cranked by hand. Baking with fresh ground wheat (and other grains, we have tried oats, barley, rice, dent corn not popcorn, and millet as well as legumes like pinto beans) is wonderful.
There is a bit of a learning curve if you are going for 100% whole grain bread--we've not mastered it yet so we usually add up to one third all purpose flour to most whole wheat recipes. Occasionally I make white bread/buns that are actually 1/2 freshly ground oat flour, my family loves them
