As winter sets in and my fingers get numb in the Streams and Creeks here in Northern California, A winter project comes to mind !
A small portable high banker or trommel/ sluice set up that could be set right in the Creek I would be working a pump to wash material and run the Trommel powered by dual water wheels ! No more classifing in to buckets and a uniform water flow for the sluice. no batterys to haul no buckets to carry a time saver cutting steps from my current program. guess its time to get the welder back out and go with green power !
WINTER DREAMS !!!

It works like hydraulic riffles/ fluidized bed (ossenberg e-tower, quicksand concentrator, bazooka gold tap, schimdt etc). 2 spray bars,top one for washing gravel, bottom for keeping the trap liquidized as a slurry. Bottom spray bars need about twice the pressure as the top ones. Heavy stuff sinks into the slurry, lighter tailings discharge through side ports.
I will watch for the pictures Astro !!
Why not just a bucket highbanker like I made? I will get some pics up shortly.
How about a rough drawing of it so we can see what you have
in mind? You know the old saying " one picture is worth a thousand words "
That way you might get some helpful feed back.
Another old saying " No one is as smart as all of us "
I built a trommel in welding class one year it worked pretty good ended up giving it to my brother inlaw who did some tweaks to it and is using it in Montana. I have some pics on my blog.
if not 3 at least please show us some pictures ok.
If you make one, Make 2, I want one!
