This is a how to video on how to build a PVC sluice stand. It is simple and easy to build. This stand can be easily modified to fit most any sluice, miller table etc. A stand can be made for a particular sluice and the sluice can be bolted to the stand for using in faster water so that it doesn't get washed off.
I also use this to make adjustable camera and lighting stands which I use to shoot my videos.
UPDATE:
I have since updated this stand and now instead of only one bar down the center, I have added another one which gives it a lot more stability with larger sluices.
