Well, my corona knockoff arrived today (thanks to Revvy's kick in the pants), and WOW you guys weren't kidding when you said the manufacturers had no idea what the word "tolerances" means. Can't wait for my next trip to LowesDepot to pick up stuff to uglify this thing!
Did anyone else's smell strongly of petroleum (oil/gas) when it came out of the box?

well reading this thread made me forget about getting a $$$ mill and trying the corona. i hope this is worthy of ugly rig status, i'm completely copying off of the water jug-in-the-lid design... i will be getting a 3 gal water jug in the next couple days to finish the deal.
i replaced the cotter pin with the 8/32 bolt, but left it loose for some play. i also added the 2 washers. i threw this together with two 5 gal buckets in about 30 min, its completely uneven, totally ghetto and on the whim with what i had laying around... and i made sure i didnt measure anything. i wanted to make sure i was paying more attention to my pints than the beauty of this piece. i have the 2 hunks of 2x4 on the sides almost at the bottom of the top bucket, allowing the entire bottom bucket to be filled. when finished crushing i will just take off the top bucket and the lower will be full and ready for the mash. the longer, vertical piece of 2x4 is there to stabilize the entire thing... the weight of the mill wanted to tip it all backwards.
i'm going to be picking up a sack of pale ale malt either tomorrow or friday and i plan on doing a few smash recipes to dial in some effeciency. i'll post up the finished product when i get the hopper set up. cheers.

That's so ugly it's purdy, Defenestrate!!! 
Since I'm off between Christmas and New Years I am going to re-do mine and go with the 2 buckets + water jug design with mine. Good by ugly choo choo, hello double bucket design.

i am anticipating a little uneasiness with a loaded hopper added to it, so i might add a hunk of 2x4 perpendicular to the bottom of the lower bucket to give it a kick stand effect. i think that will really top of the ugliness. next is as many stickers as i can find.
They need to cover it in oil so that it doesn't rust while sitting in a warehouse. I couldn't get the bolts in because none of the holes where lined up. However. I could get the plate the straighten up by jamming the pin in further and turning it 180 degrees.

DAAAAAAAMN! THAT's horrific! WAY beyond UGLY... BUT! great idea! I sometimes grind in livingroom (hell recently single if i make a mess WHO CARES) looking to ways to expand my texas flag hopper to take all grain & any suggestions on motorizing. not looking to hand crank any more than a mild since i'm making the jump to all grain...
may have a line on a spent cordless drill which only holds a charge for 1 hour... $10
will do da job! help me rig it!

Hey everyone -- here's a video of my kids helping me grind barley with my Value Village $15 score:
[ame="http://vimeo.com/8424072"]http://vimeo.com/8424072[/ame]
Why am I adding it here? Well, it's hard to see in the video, but I don't need no stinkin' washers to keep the spacing right...I've used pennies instead. I figure that's gotta qualify for the thread, right?

Here is the sexiest Corona mill ever:
That's right. 45 degree cut on the end of it, and it's long enough that I can put my leg on one side and my arm on the other to stabilize. the 45 degree cut is where I rest my foot.
Tin foil covers the area where the grain drops, and i bend it so that the grain doesn't go everywhere.
Ya know, I always thought that it was just a *RUMOR* that you could strap a board across somethings ass so it wouldn't fall in. Damn, it's TRUE!

Oh nooooo you don't qualify for ugly junk status, your kids are waaaaaayyyyyyy too cute. They just take you out of the running for anything with ugly in the title.
Great video, thabks for shariing.
I don't the pennies will work for too long though, sounds like Eli wants them.

So today I make the switch over from the "Choo Choo Train" ugly junk to the internal 2 bucket system. I went into HD to get a couple homer buckets only to find that they are priced reduced to $2.50 a piece.
I'll snap a couple pics.

How many are you going to buy before you get a barley crusher? Going cheap is good, going cheap again and again... is expensive.
30 bucks for me and I have crushed 200 lbs of grain no prob so far.
Revvy you are gonna love that bucket in a bucket. I do 21 lbs at a time, my Dewalt in low gear and trigger pulled all the way seems to be working perfect. I have to switch batteries half way through, but pull out the top bucket, turn it slightly sideways while still over bottom bucket, hit it a few times to knock grain off 2X4 and throw it in the MT.

I wasn't going to respond to this post until I had a number of batches through my Victoria / Corona rig:
https://www.homebrewtalk.com/f51/my-ugly-junk-corona-mill-station-90849/index21.html#post1408147
Well, now that I've done a half-dozen batches, and am getting a great crush and beer to match, I am. I can see no reason why this mill wouldn't do TONS of grain. It's crude, but simple, and there's not much to wear out. It's results that matter, and I'm getting them. Therefore, spending $100+ on a roller mill of some kind, making it by far the most expensive piece of brewing equipment I own, makes no sense to me.

Revvy I got some ugly junk!
and the resident brew assistant vacumning up flying bits. still need to put a cover on the front. but i have brewed 3 1.5 gallon AG test batches with it, with about 75-78% eff all three times

No they where from my boots it was a particularly messy day at work had a cummins motor throw a connecting rod thru the side of the block. oil everywhere and i apparently didnt clean the boots well enough.
She put the kiabosh on fixing stuff in the house after i had to buy a new dishwasher after using it to wash a fuel pump for a Powerstroke. (she gets a lot of flowers)

Absolutely! fuel pump got gummed up with crappy fuel from some little podunk station washed it on pots and pans with a Bunch of PBW (is there anything it cant do I use it in all washing en devours) cleaned it right out but diesel eats soft plastics quite quickly

I have an equally ugly Corona mill set up. What I also have is an old huffy stationary bike. What I am thinking of is pedal power. I was never taught to be the most mechanical person in the world. Could anybody on here with a mechanical inclination get me started?
I would imagine I would take the front wheel off and run the chain to another gear box that powers a belt. The belt would somehow spin the corona.

you can go on You-tube and look up grain mills. There is a bike powered mill on there somewhere.

I don't know the mechanical advantage in a standard bike gearing (I suppose you could always use a 10-speed!), but I think what you describe is too complex. I'd be looking for some way to direct-drive the Corona mill off the rear hub....if you have something like a 4:1 advantage, using leg power, I imagine you'd just be able to grind away the miles.....
I've got a new corona (the grizzly brand) mill, and the outer grinding plate doesn't fit flush on the shaft. Good qa/qc... Has anyone else had the same problem? I get a really inconsistent crush and haven't quite been hitting my numbers, so I think the problem is the outer plate not sitting flush with the inner. I tried the bolt in the front of the mill and it keeps the plate solid, just out of true. So, are you guys just JB welding the outer plate to the shaft and then quickly reassembling and tightening the mill together so the plates sit flush together?? Before I go through the trouble of JB welding I'm a little unsure as to whether or not the hole in the shaft will still line up with the lock nut.
Thanks for any help guys. mug:
Tough to say without looking at your mill. The bolt may actually be holding the grinding plate crooked. Somehow you need to have enough play in the grinding plate so it can spin true to the oppisite plate. Maybe filing the outer hub, or drilling the hole larger will allow the plates to align.
Not really sure the JB weld is needed. If the grinding plate is free, it might just self align when the mill is tightened.
Did you try and just tighten the mill for a finer grind?

I never jb welded mine but made the adjustments ( see pics... just haven't bought the jb weld from harbor freight, lazy i guess) Had someone here do my efficiency... (orfy? maybe ? would like o give credit where credit is due) he calc'd my efficiency at 75% on a partial mash.
Done a few all grains and came up with 75-78% efficiency! just need to cement it in place! or leave it go to tighten/lossen and get more out of it!
Look back in this thread it's there BO! It Works!~ I'm so happy I found this board... yeesss I'm Happy I'm drinking one of my high gravity beers! Honey coriander Steam (hcl) mmmmm happy! 75% efficiency brew! with lots of dry hop coriander!

I've tightened the mill pretty tight. I get a fair amount of flour, but I've never had any problem with a stuck sparge. I use a 48qt Igloo cube with CPVC manifold that has a center drain. That thing will lauter like crazy.
Do you think I should just crank it down till I get a stuck sparge and then back off a little?
If I had to guess, I have up to 5% of my grains that don't appear to be cracked. I just brewed an ESB and missed my OG by 4 points. Total brewhouse eff. was 65% (I'm not sure that I've figured out my boiloff rates well yet, so that could be part of the problem). Dead space in the MLT is almost nothing, maybe 1 cup or so. Sorry for the long-windedness...
If you still have have uncrushed grain, yes by all means tighten it up. Do so with a bit of care, if the mill binds and locks up, it could break I guess (surprised me). Is the bolt holding the grinding plate crooked. You might be better off w/ a smaller cotter pin so the plate will true up as grain is fed through.
The outer plate won't seat on the drive shaft squarely. There are the two nubs (sorry for lack of terminology) on the shaft the fit into the outer plate and I think one of them is longer than the other. Therefore one side will grind tight and the other will allow a few grains through uncrushed. I've been hesitant to crank it down to far and shred husks and create too much flour. But as I mentioned before, I have had no problem yet lautering. I'll just crank 'er down and see what happens. Is the tannin extraction from husks one of those homebrewing boogeymen/myth things??? Or is that pretty real?
I wanted to provide an update re my situation with a not square outer grinding plate.
I followed wilserbrewer's recommendation to put the cottoer pin back in (the pin holding the outer plate to the shaft). This worked really well and I saw a 10 point jump in my OG. The crush came out really even and had minimal husk shredding.
To summarize, if you're outer plate does not spin true to the inner plate, don't put a bolt in there as previously recommended in this thread! Doing so will only exacerbate your problem. Leave the oringinal cotter pin in, and crank 'er down.
Many thanks to those of you who provided advice

I too kept screwing around with it, and finally came to the realization that the tolerances in the shaft and body itself make fussing with alignment mostly unecessary and possibly counter productive.
As the grain starts going through, the shaft position is changed so that all that alignment is changed. Keeping the cotter pin in, wobbly as it may be, allows the plate to somewhat self align when grinding.
I kept going down on the adjustment until the plates would touch at some point, but not until they totally stuck together if you moved the shaft. The plates would hit just spinning by hand, but not with grain in them. This proved to be about the best grind, and got me to 75% on IPAs (maybe more on lighter beers) without stuck sparges. I'm good with that.

I put cotter pin in, Jb'ed the heck out of it, tightened it up (tight) for a little over twenty four hours. Woo Laah! I don't have efficiencies to post, but ground over a hundred pounds so far. husks end up in three pieces, less than 1/8th of the grind is flour. No uncrushed grain.
