Monster Mill 2 Crush?

[taekwondd]

I use an old rectangular cooler with a CPVC manifold that is slotted on the bottom. I would get between 70-80% efficiency depending on who crushed my grains. Last summer I bought a Barley Crusher from another brewer and he had the gap set at .025". I've never had any trouble sparging on the 15 batches I've brewed since I bought the crusher and I have been averaging 85-90% efficiency.
