After brewing a IIPA with 16 lbs. of grain crushed by cranking my mill, I finally decided to motorize. I looked at lots of versions with pulleys, but when I saw Rockytoptim's, that's when I decided to do it. Thanks for sharing your information bud! It appears to work like a champ. Next I plan to build an oversized hopper that I can attached and remove with rare earth magnets.
