[quote="MollyHatchet"]I started using my BC this past spring, and have done 8-12 grain bills through it. The only problems I encountered was after trying to run the grain bill through the second time, it would slip, and I had trouble getting the rollers to grab the grain. I took my fist and pushed down on the grain and then it would grab and pulled the rest of the grain through.
The black O ring on the drive roller broke off of mine with in two or three batches. I stopped brewing a couple of months ago (20 kegs and four cases of bottles filled), but I am getting ready to get brewing again. I think I'll take tome down time and give my BC a good cleaning in hopes of another year of good service. If I remember correctly, I keep my BC at 0.032 (?) :cheers: [/quote]
I keep mine at .030 and only do one pass crush.
I guess maybe the lesson is keep some of those o-rings on hand?
