A year or so ago I saw some posts from those having Barley Crusher problems--specifically grain hanging above the rollers rather than being drawn through. Now, after about 500 lbs, mine is doing the same thing. Gets worse with each use and is a colossal pita. I sent the BC people an email several days ago, but no response. I've searched the old posts on this which suggest the problem may be either worn rollers or an incorrect gap. I've experimented with gaps, reversed the free turning roller, cleaned, oiled, etc... no help. Is there a solution other than new rollers? Does BC stand behind their "life-time" guarantee? Do they eventually answer email?
