Diana; I (we) do not make a lot of bread so, just keep looking at the Electric Wondermill model. (No thanks to the hand crank. ) It accepts other grains as well. I think they have a demo video of them running 1000 lbs wheat through in 10 hours without it over heating.
Wondermill Grain Mill
You might be able to get the grain locally at a Coop, but if not here are a couple of sources. There are more.
25 Lb Bag Hard Red Wheat
Khorasan Grains
Drive by English lesson! The word "Lady" has its source in the Anglo-Saxon hlaf+dieg, 'loaf-kneader' or 'loaf-deliverer' An Anglo-Saxon wife of a warlord. The term eventually becomes modern English lady. In Beowulf, Weoltheow is the hlafdig at Heorot. Also called a hlaefdieg, hladig, or cwen. (Queen!)
"The word "Lady" has its source in the Anglo-Saxon hlaf+dieg, 'loaf-kneader' or 'loaf-deliverer' An Anglo-Saxon wife of a warlord."That's why I love FR! We start discussing the land area required to grow grain and, along the way, the etymology of "Lady" gets inserted into the discussion!
You just never know what you are going to serendipitously learn from our FRiends! Thanks for that aside.
