Grain Mill

There is some benefit to a 3 roller, what the 3 roller does, well the third roller, is it just feeds the grain more evenly into the 2 rollers that do the crushing, it doesnt do more crushing than a 2 roller. You can totally without issues get away with a 2 roller, the 2 roller is easier to set if you're into using feelers to measure gaps. I suggest only using grain, because thats what you're crushing, not feelers or credit cards, but people do like to use them.
Millmasters are extremely expensive yes, I can say I've not none anyone to were out a normal mill, you got to think they don't used much 5mins each batch you do. Maybe 10mins a month, its not much. Mine is still running solid, I cant remember how many batches and years I had it, but its been many.. If money is no object go for it! Cheers

I wouldnt get a maltzilla for another month or so, think they are doing an upgrade. I prefer my normal mill at this point in time, but that could change with the new maltzilla. One thing you know is a normal mill is a very simple device, couple of rollers and a crank..

These are really cheap even if you just need something until you decide you want something else, think the base boards are cheap too. bit.ly/2RollerMillKL

Sorry mate didnt see this reply.
yep free rolling and yes you can use a drill, but slow is the key, some "normal" drills dont like going slow, not enough torque.

You can use whatever you have there, just examine your grain of course. Cheers!
