I got a 2 roller Monster Mill last week and am having a bit of trouble with the crush. It’s pulverizing much of the grain and leaving some seemingly whole. Click the thumbnail below for full size.
I couldn’t leave it at the factory setting, because it shifted during shipping. I’ve got it set at .046 now (used a feeler gauge), which seems about right from what I’ve read. I know some people set theirs even lower.
I think milling speed is the problem. The MM site suggests 150-250 RPMs. I use a normal corded variable speed drill that’s rated at 0-4000 RPMs under no load. It’s very, very hard to obtain and hold a low speed.
I’m wondering–those of you who use a drill to power your mill, what kind of drill do you use and do you have any tricks to hold the speed low enough to get a good crush? I’m thinking maybe I need to get a cordless with a lower speed setting, but hate to spend the money if I don’t need to.
