I have attached some pictures of my home made sluice.
I started with a piece of heavy aluminum contractors flashing 24” X 36”. I bent 2, 6” - 90 degree sides on the 24” width, this gives me a 12” shoot with 6” high sides.
I next cut an old aluminum door threshold and cut in half long wise to use for the riffle frame. I purchased a piece 1/2” aluminum angle 6’ long, I cut this piece into 6, 11 1/2” pieces and notched each end to fit under the threshold pieces. I spaced these pieces 7” apart except for the last piece a spaced at 4” and pop riveted them together.
Next I took some old galvanized angles that came from a very cheap storage shelving and bent them over the 6” sides to make them stronger.
I purchased a 12” x 36” piece of miners moss and laid that in the sluice and placed the riffle frame on top of it. I drilled 4 holes so I could bolt the riffle frame to the sluice and hold down the moss.
Now this ain’t real pretty but in only cost me $21.00 to build.
I am sure that if I snag any gold it will be very fine so I didn’t add any expanded metal on top of the moss. That may be a mistake, but that remains to be seen.
It turned out to be stronger then I thought it would and should hold up well.
Next I will take it down to the stream on my property and anchor it down for a week or two and see what happens.
I will takes some pictures of the sluice in the stream.
The last photo shows the sluice after it painted camo.
Dude, promise we want you to have fun and find gold..
I will make fun of culvert hunting and leaving sluices because of the subject not the author.
cause it's been around for years and no one can wash the stink off.
Whats cool is that you kinda have a useable sluice now and can take it out the actual way you find gold...prospecting.
One issue and unfortunately because of the way gold moves. It's important.
You need to fix your riffles.
Any fine gold that makes the moss in the middle will get caught(you need vmat under it though)
But I noticed the way you cut your angle short of where you cut one side to attach. No biggie again cause of the moss.
But that side channel material with no sort of sto..gold WILL ride on out.
When you introduce material to the head of a sluice. when you see gold or lead you will see it push to the sides.
Not all of it but it builds up there. If that happens in your sluice making it into that smooth channel..
SHE GONE!!
Looks like you can build stuff so no doubt you can fab a fix.
If you want to keep it. Please don't leave it in the creek bed somewhere. it has better actual uses.
