You can use the Schmidt design to build your sluice.  Just print out a copy of the diagram and then measure the diagram dimensions.  From those measurements you can scale up to any size sluice you want.  I find it easier to do this as I can then build the sluice using the materials I have on hand, the pump I will be using, and the material I expect to move through the sluice.

Robert, I came up with the following when I was in the planning stage:

Prospector:
30" x 6" x 13" tapering to 9"
Trap: 5" long x 3" deep x 9" at the end of the sluice.
Grizzly-Gap Height: 1"
Grizzly Length: 3"
Taper 1.6" per foot

Miner:
48" x 6.5" x 21" tapering to 14.4"
Trap: 8" long x 3.25 " deep x 14.4" at the end of the sluice.
Grizzly-Gap Height: 1" ?
Grizzly Length: 3" ?
Taper 1.65" per foot


I made a guess about the Miner's dimensions based on the fact that Astrobouncer reported that the Prospector's trap is 5" long. I used the equation, 5 inches is to 30 inches (Prospector's overall length) just as X inches is to the length of the Miner, which is 48 inches. The equation I used is: 5/30 = X/48. I came up with 8 inches. The Miner is 6.5 inches high, so I have to assume that the trap is 3.25 inches deep.

It would be nice if someone had one to measure, but the company seems to be on the skids, since they don't answer their email or phone calls.

I hope this helps!

Hey guys,

Just in case anybody needs it, I have some pics of the Schmidt product. Someone was selling one online and took these pics, so I doubt that this is copyrighted material.

The pics weren't downloadable from the site where I found them, so I had to take screenshots....

Guys check out my buddy Indy's video, this is the guy who's letting me borrow his Bazooka so I could test it out and build mine. Him and his buddy Nugget made a highbanker out of the schmidt and also they have a schmidt dredge they show here.

Thanks for the video.  Every time I see one of these sluices operating I want to try one for myself.  The ease of operation and no classifying are a big pluses.

Glad to see one of those in action. I wonder if it really has the baffles in there or is the trap open, like the Bazooka?

Imagine this:

A piece of flat material that is exactly the shape of the intake opening of a Bazooka sluice and it would fit just inside it.

Now imagine that this piece of flat material is mounted to the outside walls of the sluice intake by a horizontal axle.

Now screw a small lead weight on the bottom edge of your flat material.

Now imagine water running through the sluice and the piece of material starting to rotate like a waterwheel, which would make the water pressure halt for a slit-second on each rotation.

Wouldn't this be a water-driven jig?

Well, you guys inspired me to get started on my Power Sluice/Highbanker.  I decided to put a fluid bed gold trap at the end of the sluice.  The first section will be 4' long with 18" of slick plate, then 30" of reverse angle riffles.  Then a 3' section with 2' of slick plate and then the fluid bed at the end.  Flud bed dimension will be 4" tall by 16" wide by 10" deep.

The images below are the start of the manifold going into the 4" deep fluid bed.  I put a pressure gauge on it so I can keep an eye on the pressure in the bed. Haven't drilled the holes yet.

Hope to have it all together this week and heading up to NC next weekend.

Putting the finishing touches on my Bazooka replica. Gotta say, I'm proud of myself for not spending the 300+ dollars... Just putting the sheet metal slick plate on and a few more coats of truck-bed liner paint and it's off to the cold cold water!

Thanks, Astrobouncer, for the specs and advice from your field-testing and experience.

Thanks Yicke, for starting this thread!

RGecy, somehow I missed your topic reply on your new equipment. Looking good!

I finally have some free time coming up with Spring break so my prototype is hitting the water this weekend. Will get pics and videos, and also I will have another sluice behind it to check tailings.
