Mill did what it was intended to do. I like being able adjust grind on my own and experiment. For the sake of it, I attempted to use hand crank, big mistake. To secure handle to drive rod, a Phillips head screw is provided. it will not hold handle in place securely. The drive crank rod is made of mild steel, and set screw damaged drive rod. Not a big deal, I used a 1/2” drill and in few minutes my grain was ready to use. I’d buy this mill again, but through the handle in the trash and use a drill.
