I recently purchased a corona mill for grinding corn for my all grains. I followed a vid from you tube for a few mods and a build I thought would keep things neat. See the post here:

I knew there were probably better mods out there ( and in here of course) so I went looking. Usge had a great post a while back but all the pics are gone so I took his info and went hunting. All the credit here goes to someone else... specifically to many of the folks over at homebrewtalk.com with reference to this specific post:

I have since changed my mill and will give you the most common recommended mods form here and from homebrewtalk as well... there are only a few but they are gold.
My original mill had the grinder above the rim of the bucket with a half bucket covering the top:
- Messy...
This didn't control all the mess and I still had dust all over. From reviewing the homebrewtalk stuff I sank the grinder into the bucket:
- Cleaner
This allows the top of the bin to be just about flush with the rim of the bucket. Now I can put a easy remove top on it with a hole cut for the hopper. Then I took a second bucket with a lid on it. I traced the bottom of my grinder bucket onto the lid of the bottom bucket and cut the lid enough to allow the top bucket to snugly fit into the lid. Now the whole thing is enclosed!
- Enclosed...
As far as the actual mill; the knockoff corona I have is some kind of craftsmanship... what kind exactly I don't know... From the recommendations there are a few big changes that are quite simple and make a big difference.
The first is the grinder disk cover (the guard over the two grinders) is poorly fashioned with a few wing nuts and tiny washers. Buy a few washers (2 to 4 has been the most common range of numbers I reviewed) and place them on both sides of the cover. I chose 3 #8 washers:
- Snug and even
The second is the cotter pin used to mount the feed auger to the revolving grinder. It's crap. The revolving grinder was wobbling all over the auger making even grind near impossible.... I got a very mixed bag of grind this way.
- Garbage
There were a lot of fixes here and many mentioned in the homebrewtalk. I chose the replacement screw. I pulled out the pin and replaced it with a 8/32" machine screw and a few washers and a nut. Be sure to align the adjusting collar correctly. It has two settings. One was just as wobbly as the pin and one was just right! (sorry... no pic since I put it together and forgot beforehand... check homebrewtalk).
The final big mod would be for replacing the handle with a motor of some sort. Unscrew the crank screw and the handle comes right off. Then place a 1/2" bolt in the auger to turn the screw. Some people use the whole length of screw, some just a small part... pick your poison.
- Screw Drive
Just thought putting all this info in one easy place could be useful. Please add what you think is valuable.
