I am rebuilding my homemade gold dredge with a larger sluice. I wouid like the know whats the best riffles to make? How big,what type, how wide, and the best speacing in between. The 2.5'' dredge\highbanker will end up being around 8' long. where the riffles are wiil be 17''wide X 60''long. I am using 1/2 raised expanded metal over vortex matting where the riffles are going. The dredge is on youtube if want to see it. It has blue barrels.(My homemade Gold Dredge/Highbanker at Thermal City Gold Mine) Kelvin31901 Thanks
