HI Art,
Just thought I would share this with you. If you have the patience & time, for a simple, small time, nothing elaborate that will not take up a whole room,
a deep well Miller Table is the best way to go for fine gold. I built my own to my specs, about 1 1/2' flat surface at the top & about 1 1/2' V mat on bottom, it's amazing how the gold stays on the flat surface, well most of it, that's why the V mat to catch the rolly polly gold. It's a low water flow and washes away the black sand slowly and most of the gold stays at the top and you can brush the gold into the deep well or like me I drill a hole on the side & brush it in there, I've changed my design a few times & to fine tune it I bought a few bags of Nome beach pay dirt, one of the hardest to work and out of one bag I recovered probably a good 97% of the gold after running it through a few times, you can't always get it all, but I find it's good for me. If you don't build your own you can buy them. There's someone on YouTube that has a "how to build your own deep well Miller Table", look up " Utahavalanch " he's really good, check him out. I use a bluish green chalk board paint for the flat surface, you can see the gold good. Hope this helps.
