That looks exactly like my crush. I have my barley crusher turned to about the 2:00 position. Never had a problem with lautering and 80% efficiency every time. But the only few batches I have done with the new crusher are in the fermentors so no word yet on "husk tannins" but I have never had a problem with that before.
PS where in VA are you located?
