First step mark and cut your plywood/paneling to the desired width and length. 
(The sluice i built in the pictures is a mini-sluice for the dry conditions and small streams in wyoming.)

I suggest you build the sluice 3 ft long and 8 to 10 inches wide. But the demintions can be customized for any situation. 

1.measure and cut the bottom to size (paneling/plywood)
10" by 3' long

2. measure and cut 2 1x4 3ft long.
 

 
Now you should have the bottom and sides to your sluice box.
