That's cool, I built the outdoor version. It's a movable recirculating system (Kind of a Keene Mini Max wanna be). But when I want to water the dead grass, I just screw the water hose to the head and sluice with clean water in the backyard. After a few buckets of sluicing, I move it to another part of the yard. I like recirculating systems, but when the water turns to chocolate milk, that sucks. Especially with the blue bowl, I always pan off the dirt and blond sands first. It's critical with a blue bowl because you have to see what's going on. 50 mesh Gold can be sent down the drain at full throttle. That's why you mark the sides for the water levels to work with 100, 50, 30 mesh, etc.

I am doing that very same thing at this moment in my wife's kitchen living dangerously. I have what is called the triple threat, a mackirk finish  sluice dumping into a blue bowl empting into a mini finish sluice for backup. I am running really clay bound material I crushed up in to 30 minus mesh and testing for clay separation and keeping the water clear. I have used the peroxide, tooth paste, soap which works pretty well, and then run pool clarifier that worked as well if not better and now am down to the run using the works toilet cleaner and it seems to be the best so far. I also use the wally world granular dish washer soap just pouring it in a corner of the tub in a small pile and it dissolves slowly. I am only using a single tub with about 25 gallons of water and two 500 gal. pumps. ran my table yesterday and about froze me out and today is 38 with a breeze so I will take my chance in the kitchen which will be okay as long as I have dinner ready when she gets home. only have about 15 days before she throws me out for Christmas. Thanks, Tom Glenn

could not get my picture to display but I don't do a lot of sluicing and when I do I use end to end calif. sluices off a trommel . if you use miners moss   you have to run a full v rubber matt under for full recovery but still a pain to clean because you either need warm water or have to dry it to get it clean. The angus mackirk work really well with a high recovery rate and 2 minutes to do a cleanup but most the time I sieve to 30 minus mesh and run all over a rp4 table and it catches it all right down to the micron stuff you need a microscope to see. I just run a 1 1/2 gal bucket of 30 minus and the water is pretty clear with The Works toilet bowl cleaner. Thanks Tom Glenn

pork chops, fried taters and cream corn did the job. I think my picture is to big so I will have to go next door and get my four year old great grand daughter to show me how. I do separate runs with different things so I don't blow my self up or make the house smell like rotten eggs. The TB cleaner has 9 percent hydro peroxide and soap and it is a pretty blue so much like the peroxide, soap, toothpaste and water formula. i did not use very much a couple squeezes in the blue bowl and a couple in the tub. my cleanup looks like it will be very god with visible gold in the box which is good cause most of this material is micron for it is tailings from a Chinese diggings but I think a Chinese tommy knocker followed me home cause I'm seeing new shadows but that's nothing for this old house. I wont run out of material anytime soon because I still have about a hundred buckets of material to run not counting 10,250 lbs of material from our claims on the diamonds that 5 of my 7 grand sons dug for me a couple years back Thanks Tom Glenn

a picture of the sluice.

Ben you are absolutely right about the platinum and other groups and this is tailings. I don't throw any thing away and probably am walking on a million dollars worth of 1/4 " I dumped on the ground in my shed, guess  I can always  scoop it up again. Have a lot of flakes but some are coated in mercury but the glory hole is a 3 ft. test whole I dug with my little one man auger I got from harbor freight and added a 1 ft. extension, puts me one up on todd Hoffman, I drilled test holes before I dug down a 100 ft. Beef stew tonight. Thanks Tom Glenn
