I have put together something similar. I am going to use a 3"  Hydro-Force Dredge Nozzle into mine. I made hole in hopper 3 inch, and fabricated a 3 inch hose coupler with sheet metal which I mounted with bolts, so I could hook 3 inch dredge hose to. I go from grizzly to punch plate to expanded metal over low profile rubber mat. And rest of sluice is expanded metal over miners moss. I will try and post a couple photos of mine. Nice job,

I totally got rid of the grizzly bars and put in perforated steel sheet with 3/4 inch square holes. It does mean I have to rake rocks out by hand  a LOT more, but I won't lose  bigger gold or other stuff out the back so much, like coins, copper nuggets, arrowheads, jewelry, etc.

I also squeezed in 4 x 1 inch diameter spray bars so it pounds the gravel better from all 4 sides. I hardly lost any small pea size gravel and sands out the back like I used to with the grizzly bars. I would guess 95% under 3/4 inch size went into the sluice. In my sluice I have a foot of bare metal under the hopper, then 8 inch of Keene Miracle mat, then 16 inch of raised expanded aluminum over carpet and moss and just a few stream riffles.

It works better now than ever before, nice smooth water flow and no clogged riffles. I am just using a Honda WX15 pump and 70- gpm , might try my Keene P90 pump this year and 2 inch dredge nozzle and hose.

And I have the rear end mounted on 16 inch wheelbarrow floatation tires to make it easy to move. Had to weld an aluminum tube axle under the approx. center of gravity spot.

I can also mount the engine/pump on top of the sluice just in front of the hopper if needed. Vibration to settle out the heavies?

      I've been trying to come up with a unit to recover gems dry, but finally realized that the "granular convection" problem can't be defeated. In the process of building and trying various ideas, I came up with this unit. While the dry recovery of gems requires some very tight classifying, and thus isn't practical, I tried it for gold, and was simply amazed at its abilities for heavy metals. I have tried it on all sorts of raw materials, running bank feed at roughly 2" minus, and have yet to find a material it doesn't work on to one extent or another.
       I ran it dry...no water, on damp material at the LDMA Blue Bucket outing near Baker, Oregon a few weeks ago, and recovered flour and black sand from old tailings from previous outings. Running wet, the day before, on new material I recovered very near 100% on black sand and gold in front of several witnesses. They suggested re-running the tails, and zero black sand, or gold was found. Last weekend I attended a local club outing at Salmon, Idaho. The material was a heavy clay with lots of rocks....not a fun material, at all. At the common dig, one of the guys next to me, running a highbanker, mentioned that my little unit was handling the clay really well. I was the only person running 2" minus directly into the machine, and the rocks were agitating the material so the clay broke down, and the rocks were mostly clean before they went out to tails. The day prior to the common dig I went down to the locale the common material had been hauled from, and ran the material dry. This was  a nasty, damp material. I expected nothing and was surprised to see both black sand and gold when I did the cleanup. Certainly I lost quite a bit, but any recovery working dry from damp material is an accomplishment. This unit works wet or dry. Very little dust running dry. Very low water requirement when running wet...roughly 50 gallons/hour.
       The full utility US Patent has been applied for.
       You can see the prototype running at Bonanza Bar on the Snake, along with pics of the recovery here:

      Hi there RR, All this gadget is doing is mechanically classifying material into a gold pan. Nothing you couldn't do with a manual classifier over your gold pan which you could possibly get away with. I know with my sluice boxing I made & use a bucket classifier than can process a lot of material pretty quickly to feed down the box.

      Super Cool! If it can handle the punishment of Hardcore Diggers? Enjoy! Cheers, Ig

      I tripped over this extensive article, available as a free download. Here is the abstract:
      The article sets out to clarify the special character of the North American gold pan and why it remains so popular – in spite of widespread dissatisfaction and many modifications and innovations. The North American pan is distinctive in being circular with a flattish floor ringed by an outwardly sloping wall. Its identity is confused by over-use of the terms 'pan' and 'panning'. The North American pan gyrates in a distinctive orbital motion driven by both hands of the panner. Although many other motions are resorted to (tapping, to-and-fro, tilting, and tick-tock), it is the orbital motion and flattish floor that together distinguish the pan from most other hand-held gravitational devices. In spite of its enduring popularity, no scientific tests have been published on the North American gold pan or for any of the innovations covered by 30 US patents awarded since 1861. It remains unclear if the North American gold pan is more efficient at recovering fine gold and flat gold than is a lotok, batea, dulang, ninja bowl, grizzly pan, mat, bucket or any other sort of hand-driven gravitational device. Some innovations are long-forgotten but merit attention. For instance, bars to keep the panners hand clear of the water, cables to hold large heavy pans, and several pans designed for panning without any water. Traditionally the North American gold pan was a combined digging and washing device, but today most models are not designed for digging and require a spade to be used.

      I have been working on this for a couple weeks.  It's a collapsible, customizable, self-contained, super light, 3D printed sluice box!  I know there are other folding sluice boxes, but none of them actually fit in a backpack, or are light enough to carry in one hand.  This solution would be EXTREMELY helpful!
      I'm on my phone trying this, so when I get to my laptop, I'll write in a bit more.
       
       
      So I'm currently in the CAD stage.  I have a guy that does 3D printing for me, and his machine is limited to 12"x12"x15" so I might have to shrink the size of the project down to fit, as I don't have access to, or can even afford, a larger 3D printer.
      I have this up on Patreon to attempt to raise some funding to start getting prototypes printed, and boost this project towards the finish line!
