Hoser John said:Sounds good to me thats what ya want. Too slow and you see air bubbling up and blowing out gold,too fast and flat as a fritter. Different gravels need slightly different feeds. Nice round is ez like a dredge but those slate filled feeds can be problematic. Paint some lead shot weights red and see where they end up in the riffle bed. Like a dredge/sluicebox should be in the first 3-4 riffles. On the punchplate seperator is there a foam backed tape dead spot where the riffles matchup that kills air flow under riffle ? Jim Straight is a great author who has published some great books on drywashers,methodology and prospecting in general. He has pictures of the first,and best,offset weight elliptical vibrating drywashers made by my company PESCO back in the day. We changed drywashing forever with my invention and absolutely refused to patent as all I ever wanted to see was others get more gold. A good quality facemask is a absolute necessity as Desert/ Valley fever abounds now and a horrible way to die just to dig for some gold-tons a au 2 u 2-John
