I've done the drill thing but with a normal 5 gallon batch I have gone back to hand cranking. I just really enjoy the feel of the malt being crushed and the resistance against my turning the crank.I also like the sound, which I don't hear when I hook up the drill. For an ordinary batch, even though I put it through twice, I like hand cranking. In fact its one of my favorite tactile parts of brewing, it feels like I'm part of history.
