    They put quite a bit of work into getting the angles right on the bluebowl, I have yet to see a homemade one work right.

    I've never actually used a bluebowl, so I'm not sure what angles you're talking about. I did a test run yesterday and considered it a small victory that it didn't leak, lol X4 is right though, it needs a few tweaks...walls need to be a tad higher or shave a 1/4'-1/2" off center cone because I'm seeing some overflow. I love fluid dynamics...an interesting thing happens when it's perfectly balanced - the same thing that forms on the sluice when you get the water perfectly balanced - you kind of get those 'V' waves throughout...I don't know if it's just cross currents or what, but when the bowl and flow are setup just right, it looks like a petunia of water. I'll try to take a picture, but the glare and fact that the water is clear might make it tough to see. It's also when the bowl is the most efficient at removing materials.

    I will say that I added some flow controls that are making a HUGE difference with run #2 tonight. It's just finishing up, and while I don't want to jump to any conclusions, there is some yellow colored stuff at the bottom.

    Added the flow controller, but like N-Lion mentioned...some of the angles need to be updated

    Making progress Turns out the angles aren't all that bad after all. Properly classifying the material and turning down the water flow so that the vortex could do it's job proved to be a big step in the right direction.



    Here's the way the bowl finished up...pretty happy w/ the results (would have been happier if there had been gold in the bottom ):

    You need a pump that runs 2000 -2500gph for your sluice. This playlist will give you a few ideas on your bowl. The son of the guy who originally patented the blue bowl is a member of this site.
