[QUOTE="Goldtarget, post: 81884, member: 2152"] The Walbanker is similarly sized, but a sluice wont always have that sort of volume or pressure, using it as a guide and its principles will help. I have built several projects at 1200, including a sluice, but use multiple configurations depending on material and flow. The trick here (and I'm not taking a shot at the breadcrate, I've just never used it in a sluice) is to get a decent amount of liquidity happening on the slick plate, the better this happens the better the capture. Vrib and expanded (raised) do a great job and some moss is also a great option. In moderate flow with classification to 1/2 inch I would run on a1200 system at least 500 slick to 400 moss with ribbed or backed matting (the expanded if flat will be fine on is own) and 400 with riffles or expanded and moss here to if not already in it. Alot of thought goes toward no moss after slick plate but i find if you use it upfront under expanded it will capture just a much as without. So to recap, 500 slick, 400 expanded to floor vrib or moss, then the rest either expanded or riffles over moss with vrib underneath or backed mat. That's my 2 specks worth others may disagree, but a Doc says, you can't have too many interruptions or capture points, expose the gold to as many variations as you can. [/QUOTE]
