I received a grain mill for Christmas, it is the barley crushed mill that is quite common. I have not reset the gap from factory setting but my question is if I am using a power drill to run the mill, could the speed of the mill shred the husks to much? If so what's the easiest way to get the right speed dialed in? I ask because I am having some clarity issues and believe I am extracting far to much tannins. Thanks guys!
