I just got this mill recently, but have had problems with the drills I've been using. The first drill was just not powerful enough, so I got a corded drill. I was too nervous to give it full power, but this drill wouldn't start the rollers without giving it full power quickly then backing off.... eventually both drills started smoking and I finished the grist off with the hand crank. What do you think? A drill with more torque?
Cordless drill no good (usually). After much
experimentation I've found that running the drill flat-out at 3000rpm all the time produces the best results. And it doesn't start smoking LOL though I got that with my Black&Decker 18v.
Really, the main problem I see with the BC and it probably is true with most mills (WAG) is that the variations in grain's kernel-size coupled with fluctuations in humidity often requires gap adjustments just to get the stuff to feed through. I grab the chuck and work it back and forth till I feel the grain "bite" and then I let it rip.
Finally concluded I'll just back off on the gap permanently since a dubious couple points in efficiency no longer matter to me. I just want the brew-day to go smoothly.
