Hi,  I am starting to think about doing some milling.   I see there is a grain mill attachment for KA stand mixers.   This is so much less expensive than a standalone mill, so I was hoping to hear from people whether these are useful or not.   I would be interested in milling say around 1-2 pounds (500+ grams) at a time.   So I am wondering how long that would take, and whether you can control the grind well enough to get for instance high extraction flour.  I have had my KA for years - since long before I started making bread - and I use/abuse it a lot.   Can it stand up to milling?   Thanks so much for  any info you can give me.  -Varda
