I brewed my first two beers today with my new Barley Crusher instead of the LHBS crush and saw a drop in efficiency. Everything else being equal I went from 74-75% efficiency with multiple LHBS batches to 70-71% on the default factory settings for Barley Crusher. The dial settings for my crusher have one at 11:00 and the other at 12:00. Is this normal? I was assuming I would get better efficiency crushing my own grain. Obviously not the case here today.
If it is recommended that I use a specific gap setting I can pick up a gauge at Lowe's what are everyone else's default or custom BC settings or gap?
Side Note, there is a black rubber band looking thing about 25% onto one of the rollers. Looks out of place. Is this normal? I'm going to post this in the equipment forum as well.
EDIT: Found plenty of info on the black band / O-Ring. Looks like it's a non-issue and wll eventually fall off.
