Step 6: If looks could kill

I'm sure that when I was asleep, this is how it worked then....Only what I dreamed had a pistol-grip attached right to the barrel and didn't need a shop-vac. Why can't this work! Doh! And yes, I put the barrel in backwards on purpose. I at first thought, considered that the holes for the porting would provide enough entry for airflow, but on looking at it, I didn't even try. I didn't even want to try just opening the hopper fill hatch and let the air go through all the balls in there, traffic jam sort of thing I suppose.
