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.

So I hesitated for a while before taking the plunge and using steel. But I decided it was high time I learned how to weld anyway. So I bought some 1/2 x 1/2 angle stock and some 1/2 x 1/8 flat stock. My intent was to use the flat stock as rails on either side of the sluice and weld the angle stock between them to make riffles.

You need some angle/drop to help clear out the drop riffles.
