So, indeed off topic, but I've seen your frustrations...My Barley Crusher died after only 2 years (and 60ish batches). The knurling wore to the point that I'd have to triple crush, starting at .050 or more just to get it to grab. Adjusting down as I could. Some runout due to bearing wear as well. My own frustrations after spending about an hour each brew day adjusting and readjusting to mill for each batch, led me to buy the SS Brewtech mill and cart.
I know, I know...very expensive, but worth it to me. I now just measure my grains the night before, wake up and light my burner, mill my grains (15 lbs or so in 3 or 4 minutes), and go
. For those interested, -4 setting for rye or oats, -3 for everything else. I BIAB. Today I hit 80% efficiency (compared to 68-70% prior).
