How do I set up dredge punch plate/classifier?

[Hoser John]

great dual size ramp for over/under classification with a riser to set height over riffles(2) on top and it keeps oversize from ever getting to the under at the same time.John

I agree with John. The punch plate actually creates a vacuum and pulls the heavies down. I trap plenty of small gold under mine! Nuggets will either drop out in the back corners or the first ripple.
