what kind of maker do you have? I have a zojorishi....as long as you can open the lid while kneeding to add flour if needed it should work.
I've always made mine in the bread maker because I hate the mess, and it's always turned out delish!
Are you wanting 100% whole grain or would you use a small bit of white flour? Are you using commercial yeast or trying to do sourdough?
I don't actually measure much, but about 4-4.5 cups of flour is a good sized 2pounds loaf. I make two 1.5 (about) pound loaves at a time in teh breadmaker and bake in the oven....I use about 7 cups total flour I would guess
I don't have time to fully explain my process right now....I use spelt btw this is basically what I do I can try and get a more exact recipe if anyone cares

I think for mine you have to be willing to sprinkle a little unbleached white flour or unsoaked flour ( I do white, probably a cups worth for 2 loaves) because it jiust works better
I melt the butter, I do half buttermilk half warm water (you could use yoru whey), add the flour and stir, don't use the full amount of flour you'd need fo ryour loaf....next day dissolve yeast in a small amount water and your honey, let foam/proof. Add your soaked flour, salt. This is where the white flour comes in. I've tried to do 100% soaked in the breadmaker it just doesn't come out good, and actually even if I do it by hand I don't like it. I find it turns out better if I do as I said above, and after the yeasty proofed water and soaked flour are combined start sprinkling white flour untill it's a dough ball, then let it kneed. If this make sense I can try to get a more exact recipe (as I've been meaning to do anyways).
