I removed the handle on the drill that was 1/2" pipe. Ran it through the ply wood. With a little space to match my MM-3, a nut on the bottom, and it was like having a direct drive motor for $20. I can't believe I fought the drill in one hand, grain scoop in the other for so long. I'm making a hopper addition for the big grain bills and I'll be set. If it had variable speed, all there would be is make a mount. It really did improve the crush.. If I batch sparged, the finer crush and flour wouldn't matter. That causes problems when fly sparging.
