    I either see some uncrushed grains or just some supremely intact husks.

    There is minimal uncrushed grains. I was afraid of going tighter.

    This one. Although I attached a drill to it. Screw that hand crank noise.

    Second pic is stuck mash city. First pic looks ok. I assume you are using something like a corona mill, not a roller mill.

    A roller mill crushes and won't chop up the grain like that second pic usually.

    Correct. Corona. To go from the first pic to the second pic (or rather second to first...) I backed out the adjustment screw maybe an 1/8 turn. Maybe that far. I think I need to condition the grain with a half cup of water sprayed over it and let it sit for a few hours next time.

    Conditioning should help a little. Anything to make the husk more pliable. But I don't think you will get much better with the corona since its more of a cutting mill than a rolling style.

    Maybe I crush it a bit finer and toss in a bit of rice hulls with every batch. I'm ok with that.

    i'd take the crush in the first pic over the stuck sparge in training in the second pic. have you tried running it through the first setting twice? that might give you a more thorough crush without shredding the husks as much.

    I have not. I actually never thought of that. I suppose I just figured that if I ran it through twice it would get crushed up more. Not necessarily crushed the same but more consistently. Either way, this is the second batch I've ran through this mill so I'm definitely looking for ways to improve.
    The efficiency on this batch wasn't good. Before blaming the crush I'm going to rule out the stupid thick mash I had today. I'm sure that hurt a little.

    I've pulled some of my best efficiency with a thicker mash, less mash water means you can rinse with more... as long as everything gets properly wetted and temps are stable throughout.

    As to you're crush: looks good to me. If it's not getting stuck try it a hair finer (or mill twice). Use a feeler gage so you know how it's really set. Measure the gap on three spots on the mill as those things are not built like jet engines. As you brew more than I; you can test things. Take the gap down .001" every time till things start run too slow.

    can you measure the gap on these? i thought that part was enclosed.

    The gap is open and could be measured. But the rotating plate is really sloppy. I'm not sure measuring is possible.

    This. Or if you have three sets of gages....

    I've been using a meat grinder with a grain mill attachment. I swapped around some hardware so it has some slop and it works well. I also have a stone flower mill, but that's useless for brewing. Just picked up the corona style and haven't played with it yet.

    Meat grinder isn't far away from the corona. It's a great mill for the price, but takes a bit a finesse to get it where you want it.

    Not much. You just need 2 burr plates instead of a blade and perf disc. Ain't happening.

    If it's a fixed plate grinder don't bother (i've tried, it only works if it's wet and not well even then). If the plate rotates then it's an option, not a good one, but it'll work (and you'll work more than you want too). Coronas turn up at flea markets (got mine for 5 bucks) and the going price on ebay is 17 bucks + S&H (they are hefty). I can't say if they are that good yet, but lots of people use them...

    I'd think a solid drill press, vise, and some careful measuring might do the job. Clamp and drill both end plates together to eliminate the need for extreme precision.

    true... i suppose. i have a small milling machine in my garage. It takes up a lot of room. A Bridgeport would take up a lot more.

    As I was making my coffee this morning I remembered that the standard electric coffee grinders they use in grocery stores are burr grinders, almost identical to a corona. but electric. I've taken them apart and they are quite adjustable.... I'm sure they cost more than a roller mill, but if you ever see a used one, bam.

    Very easy. Depending on what you want to do it can be as simple as a piece of mdf with a slot cut out in it for the base, and the hopper can just be a bucket with a hole in the bottom.

    adjustable gap isn't really all that necessary. it's helpful if you dont know what the gap SHOULD be... so at least you can tweak it until you find it.. but once you find a suitable gap, you typically just lock it down and run it forever... (until your 3yo turns the knob during your live brew cast)

    i have an adjustable roller mill from JSP. i have a factory scribed line on the bushing block and the adjustment knob. i've adjusted it narrower and wider than that scribed setting line. i get the best efficiency if i just set it at that line ant leave it alone. i dont even bother with it anymore.

    i also have the gear driven option on mine. that i would recommend if you can afford to add it. it ensures that you are crushing the grain between the two moving rollers, instead of smearing across the face of one roller which is moving slower than the driven one.

    This was the result of a double pass because I thought the first one was too tight so I backed it off. Conditioned grain creates substantially more stress on the drill than dry grain. I sort of like the conditioned two pass process. I might back the first pass out a bit and tighten up the second pass. Really, I need to toy around and then put some reference marks on the mill.
