you remove moisture while you roast, which won't happen from grinding. btw, Arie X also roasts his coffee - he has a nesco roaster. what kind do you use?
if you put in 16 ounces of grain, you should get 16 ounces of flour minus any small amount that sticks to the mill stones. i've been grinding my flour in a coffee grinder, but i can't get it fine enough. when i put in a couple of ounces, i get a couple ounces of flour if i scrape under the blade.
i have friends with the electric wondermill and they love it. i wanted to get an electric mill, to be honest, but my husband wants something that will work with no electricity, and i can always get the drill attachment.
I have a Huky roaster. It roasts one pound at a time.
A decent quality burr grinder should be able to get you to the consistency of flour. It'll take some time and work, but you can get there.
We grind for Turkish coffee now and then, which is about the consistency of flour.
