My best friend and I seen this on UTUBE so I will not take the credit for it, who ever did come up with it was quite smart. I did improve on a few things though. One thing I could not find was a 3"X 1 1/2 "Y" so I used a 3X3. Worked out fine but I have a 6.0 vacuum otherwise I might be loosing too much vacuum out the top. I used old arrow shafts to act as the tumbling aids instead of buying wooden dowels, "I'm cheap!"
The vacuum breaker on the top is just a cap that I drilled through the cap and the short PVC extension. I just turn this to expose more or less holes, when you stop feeling corn getting sucked up the hose, your there!!!
Enjoy the picture and steal the idea folks, it works great!

i use the same setup to clean pellets. nice

If one was to build this what would the shopping list look like?
