I've had my Barley Crusher for about a year now. I've put at least 300 lbs of grain through it now. I've calibrated the roller spacing with some feeler gauges so that the gap is 39/1000ths of an inch. I have a hell of a time sparging. So much so that I started using rice hulls in every batch about 6 months ago. I still have some problems.
For those of you who have barley crushers, what do you set your gap at? I'm thinking I'm going to have to bump mine to 41/1000ths for my next batch.
