How To Set The Right Sluice Box Angle (Tips & Tricks

A sluice box should be set with a 4-8 degree angle. Another rule of thumb is that the sluice should be angled to drop roughly 2 inches per foot of length.

Over time, as

I cut up the steel pieces without too much difficulty, even though I only had a hacksaw for the job. I don't have a lot of metal working tools
