I'd like to see it handle a really big, modern load like it was designed to do...
When I see the direction the augers turn in relation to how the spirals are impressed in them, I would have thought they turned so that the flatter, "paddle" side would lift and flip the load. Instead, the augers turn so that the load is shifted back and forth, and for the speed the augers turn, the load doesn't seem to roll at the same rate.
Very interesting indeed! Sure beats the impellers-on-steroid machines that are out there now.
