The Inside Bend Device

This is a downward corkscrew of corrugated tubing that quickly captures really fine gold and nice pickers. From 3/16 of an inch down to -100 and smaller. It can process a quart of concentrates in 5 minutes. You can build it in different configurations, but there are only two that I built like this. When it's finished there's a teaspoon on concentrates, easiest clean up without loses.
