I did a search and I couldn't find any specific write-ups (could have just been oversight), so I thought I'd share how I motorized my Victoria Grain Mill using a hand drill. I would assume that the same parts list would work for a Corona Grain Mill, but since I don't have one of those, I can't verify. But after one use and grinding 13# of grain by hand, there was no way I was going to go that route again. Here we go:
Parts List (all from Home Depot):
1 - 12" x 5/16-18 Threaded Zinc Rod (Part Number: 030699170104) - $1.17/each
1 - 5/16" Lockwasher Medium Split (Part Number: 0000-590-832) - $0.17/each
2 - 5/16-24 Hex Nut (Part Number: 0000-721-825) - $0.11/each
Step 1: Remove the hand crank from the mill
Step 2: Thread the Rod into the Crank Screw position (hand tighten)
Step 3: Thread the first Hex Nut onto the other end of the Rod until there is enough room on the rod for another nut
Step 4: Place the lock washer on the rod
Step 5: Thread the second nut onto the rod, tighten firmly with adjustable wrenches
Step 6: Using a 1/2" socket on your drill, you can now have a motorized Victoria Grain Mill!
