DIY Grain Mill ideas? (homestead forum at permies)
A rolling mill. They use much, much less energy than grinding, so handcranked should be OK. They don''t have wear surfaces like most mills, and are mechanically fairly simple. Rolled fine enough, sourdough can be made without any grinding. Rolled a little coarser, you can make hot cereal...if I understand it correctly, rolling your own fresh and coarse enough has all the benefits of steel cut.
