Lengthwise, the sluice box should be angled around 5-7 degrees to allow pebbles and other materials to pass through easily.

If the current is strong you may need to lay some stones against the edge of the sluice to keep it from washing away.

Let's talk a little about what happens behind the riffle in a sluice box. If you only run water over the box, it does not take very much water-flow to maintain fluid movement behind the riffle, because there is nothing solid to obstruct the flow. But the average streambed material (rocks, gravel and sand) weighs around 4 times more than water

The aluminum riffle cage and box are built to last and will stand up to many years of use. The expanded metal riffles help keep the gold in the box and prevent rocks from knocking it loose. The black ribbed matting in the bottom of the sluice allows for fast gold identification, followed by 36 inches of miner's carpet for added protection.

The recommended spacing between riffles is twice the height. Measure from the top of the leading edge of the riffle down to the sluice and double that measurement as the spacing between riffles. That 2:1 ratio is the formula for creating the proper vortex between riffles. (provided the angle of the sluice and the flow are adjusted accordingly)

In my favorite home built drop riffle the first 8" or so are 1/4", 1/8" deep dados spaced 1/4" apart. Imo it pays to have a drop riffle with a couple different shaped riffles. The plastic drop riffles that are just three feet of the same sized riffles never made much sense to me.
