The riffles in both boxs are 1" high & spaced at 3.25" but the 3" box they are 45 degree & the 4" box they are greater probably 60 degree like you said. The other day I made different sets of riffles to try in my 36" X 9" box.
This sluice has even been operated at a 45 degree angle and still captured gold, including fine gold. But for most purposes the angle of use should probably fall in the range of 5 to 15 degrees, depending on needs. (For reference, 1.5 inch per foot of length equals 5 degrees. 3.5 inches per foot of length equals 15 degrees) Steeper angles ...
approximately a 10 degree angle. a. The angle may have to be re-adjusted once the proper flow has been determined. The angle of the sluice to determine the proper flow is generally as close to level position as possible without allowing the gravel to build up over the riffles. If the sluice box is tilted too much the material will flow over the ...
Now, the rules of thumb on the sluice box is that the sluice box should have a one inch drop for every foot of sluice and that will create a proper flow now as far as the amount of water on top I see some guys run it a foot under water and it still works for them. Me? I like to have mine with about half way sticking up out of the water ...

Riffles cause small barriers to the water flow which creates eddies in the water, giving the heavier material (black sand and gold) a chance to drop to the bottom, behind the riffles. The "upstream" end of the sluice can also have a flare to aid …
The sluice needs to be angled correctly in order to allow the gold to settle into the riffles, while still allowing lighter material to wash away. The ideal angle can vary depending on the material being processed and the water flow, but a general guideline is to aim for an angle of around 5-15 degrees.
Early sluice boxes were nothing more than wood or fine clay troughs. Many different types of riffles were tried, stone, logs, grass, sticks, etc. The pioneer prospectors found that a rough wooden sluice with raised wooden slats worked best and was easy to build. The principal behind the sluice box is the same no matter what design is used.
I am looking for the best setup in my sluice box. I reckon I might be missing a little bit of the fine stuff whilst sluicing. Whats everyone's take on the mesh versus "straight bar " riffles.

This sluice went through several revisions and lots of tweaking before getting to this finished product. You can see the entire evolution of this project on my web site.
Here is a pic. Facing the wood stove, the chimney pipe would go up and out the left wall (The wall with the insulation in it). If I did use two 45s, technically I would come up 1 foot, go into a 45, go diagonally about 30 to 40 inches, go into the second 45, go about 6 inches horizontally and then continue horizontally with a 2 foot section of stainless steel double …
