    I’m thinking about getting a grain mill. Hand-crank is fine as long as it can be converted to electric in the future, either with a drill motor or dedicated plug-in standalone motor.
    Which parts can develop looseness over time or show detrimental wear?
    What should I be wary of, other than signs of normal wear and tear?

    Any other features that are a "must have", like 3-roller over 2-roller, gap settings, etc?

    Thanks in advance.

    These are of interest in case I come across a used one on the cheap.

    I use a old Victoria or, corona sty which is not popular on this site, but it works well, adjustable and I have a drill on it.

    Whatever you buy, after a while you will want the drill. Saves a lot of time.

    “Any other features that are a "must have"?

    I am uncertain whether it is an absolute “must have” but I would recommend that you buy a grain mill that is adjustable. There may be a time (e.g., differing grain types, efficiency optimization,…) when you would like to change up the gap settings.

    Cheers!

    Being adjustable and convertible to a drill would be my old concerns when searching for a mill. I have the cereal killer which only has a 7lb hopper. In hind sight I wish I got one with a larger hopper as I often make ten gallon batches that use 20-30 pounds of grain. But still happy with the 99.99 I spent.

    FWIW, I always do a double-crush; one at 0.060”, the second at 0.025”. All grains sail right through the mill (both times), good efficiency, no stuck spares.

    Sorry...no stuck sparges. Autocorrect (and a long week) got me.

    My first mill was a concerted pasta mill I picked up at a garage sale for 5 bucks and took a dremel to. Got 75% efficiency, ha!

    I’d say beyond adjustable gap, there are no ‘musts’.

    Accessories: 1) plan on mounting the mill to something that can take a soaking (it'll be rinsed each brew day). My mill came on a fiber-board platform that is slowly delaminating (and stinks). Get a heavy piece of Marine-grade plywood and be set for life. 2) a good feeler-gauge and lubricant to keep it from rusting-out. 3) my area has a corrosion problem, so went with SS mill . . . YMMV

    I would have never thought of rinsing my mill. I just occassionally brush mine off. Do you condition your grain before milling, or is the rinsing somehow related to living in a high humidity area? I'd be interested to hear if others rinse their mill. Cheers!

    No grain conditioning, but after every use I have a very noticeable layer of grain caked on the rollers and dust on the hopper, more so than a brushing will correct. If I set the base down on a counter-top it leaves a nasty grain-dust imprint. So, it goes straight to sink for a thorough rinse (top and bottom). I have no other experience than high-humidity milling . . .

    I don’t rinse, but I have the same dust / flour issue that #PortLargo mentioned. I brush it off, cover the hopper, and set it on a paper towel.

    Thanks all for the feedback.

    My original posts missed the mark of my true curiosity. Instead of “must have” it would have been better stated as “must look for if buying used”.
    Then I got to thinking that a grain mill is a simple machine, almost primitive…..a set of rollers geared to counter-rotate and powered by either human or electro-mechanical means. About the only bell or whistle is a way to vary the gap.
    It seems the main thing to look for in a used mill would be if the rollers turn and whether the gearing has excessive slop.

    I expect to eventually use a dedicated drill or standalone motor but will likely do the hand-crank thing initially (unless a killer deal comes along).
    The fact that you said “old” coupled with input elsewhere of folks who’ve had their mills for a long time, suggests they can have good, long life if treated appropriately.

    While I’m not averse to spending extra bucks for something that’s gonna last a lifetime, I like your early approach. It’s one that adds to the self-satisfaction of “doing it yourself”.
    Not that I’ll now look for a pasta mill in lieu of a grain mill, I'm curious what it was that you took a dremel to.

    Thanks for the marine-grade tip. My environment is pretty humid but certainly not as much as yours....plus I don't have the salt air to contend with. I’ll probably check my mileage before dunking, but the SS recommendation is great.
    Never even crossed my mind I'd need a feeler gauge....just figured there'd be a knob with markings or detents or similar.

    My mill has one “driven” roller, and one that free-wheels. I already had feeler gauges and a cordless drill, so no-brainer there. My mill’s adjusters have gap markings, but for the minuscule time it takes to use the feeler gauge...

    I think that if you get your own mill, you’ll be happy that you did. For me, it was clearly a step that helped my efficiencies up to where they should be and repeatable.

    No rinsing for me. I am able to 'clean it' via brushing.

    Cheers!

    I bought this one, regularly sold at $99, and remain pleased after about 4 years. More expensive ones are out there with a lifetime warranty, but I've checked the lifetables and figure I probably wont need one that lasts forever.

    Ya this is a good cheap mill. May not last forever but it was a good entry point.

    Thanks for the tip on the Cereal Killer. Just ordered it from AustinHomeBrew.com. Free shipping plus 11% off orders over $49, total for the mill $88.99.

    I brush off my mill and the same fiber board that @PortLargo mentioned. I oil it every so often and keep it inside so it doesn’t rust. I’ll change the rollers to SS when it is necessary but that’s an unneeded expense for now. The hopper is galvanized so I do spray that off and leave it in my garage.

    What type of oil do you use and what specific parts are you applying the oil to?

    Cheers!
