Looks awesome. And for 1000 $ it better be! Can you rig up a V-belt drive?
Some philosophy and commentary from the peanut gallery:
Grinding your own grain simply can't be easy AND fast. There's a certain amount of energy that it takes to crack wheat and there's no way around that. If easy or fast are your objectives, grinding your own flour may not be the way to go. In the past I would make a big batch of bread every few weeks and freeze half of it for later use so it didn't go stale. But grinding 12 C of flour takes time and effort. Since then, I've basically cut out most of my bread making (because I don't need the carbs for my level of activity) and haven't ground more than about 2 C at a time. That's more manageable but it still takes a certain amount of self-control to do that instead of breaking into the pre-ground flour. And, unless you're violently opposed to cake, you'll still end up buying some flour anyway.
I suspect that the reason everyone likes these higher-end units is because they feel good and smooth when you crank them. I have the WonderMill Junior which has no flywheel and doesn't feel like quality, despite being perfectly serviceable. Those of you who tried it in the store probably didn't have to grind 2 C flour ASAP for buscuits (timing is everything in the kitchen) without AC. So although it seems great in the store, it's like trying on a pair of shoes or taking a car for a test drive. When you use it exclusively (as we have) for several years, new priorities emerge. (Sounds like marriage, doesn't it?)
