try adjusting the spacing of one inch angle iron in your transparent sluice box. see if it does make a difference. try one at one inch two inch and three inch. contact me at my email if you do a video . i would really like to see it. you do a great job on your videos. robbiesrock@hotmail.com
@JINGLEBOMBSS okay, well the plexiglas sluice isn't all that big, and the riffles you see in there are only 1/2 inch profile riffles, about what you would be using in a highbanker, hand feeding material to it, size or profile of riffle dictates the spacing, water flow dictates the slope or pitch of the sluice, and a combination of these two plus the size of grizzly classification generally is instrumental in the type of gold recovery to be expected, example, with 1/2 inch rocks bouncing
@JINGLEBOMBSS your riffles you wouldn't or shouldn't expect to have the fine gold recovery that you would get if you were only having 1/4 inch or 1/8 material running through the riffles. have tried a number of configurations, and have found that the 3 x profile height works about the best for my applications, later this winter will most likely redo the how riffles work series, but a longer more in depth set of videos, still figuring out shooting and editing, only have 1 1/2 years, on computers
if the angle iron is one inch then what you are saying they should be spaced three inches apart. other studies that i have read says that three inches is to far and the material will be blown out by the flow of the water. i love how you made the sluice so we can see the flow of the material. i have made many riffle designs and have found that the one inch angle iron at 15 degrees tilt upstream spaced at 2.5 inches apart seems to work real good on fine sand. see if you can play with the spacing
your riffles should be 1.5 inches to 2.5 inches apart. look up the yukon sluice test for full study on the riffles. this is a great demonstration you are doing
Looks good man

the riffles need to be more than one inch apart or less than 3 inches apart to create the correct vortex

if the riffles are less than 1 inch apart they do not create the vortex and if they are 3 inches apart the streamline takes the material out and away
