I'm building an over/under and I was wondering what the school of thought on using ribbed carpet or miners moss in the lower section. I'm leaning more toward carpet because of concerns of loading up the moss with way too much in cons. But, I'm looking at the expanded sitting on my carpet and worry about the occasional gap that might let the heavies slip through. So, I'm kinda perplexed. Would the gap under the expanded that let a piece through get caught by the next section of expanded that was sealed up and so forth? Or am I just over thinking this?
Thanks for any comments on this.
You have expanded under your dredge riffles-now thats been costing ya. Expanded is ONLY for a sluicebox with a hungarian(lip to seal at the bottom)and not a modified hungarian(lip at top)dredge riffles. Just take a flashlight and shine it on them riffles--see the light underneath--thats where your gold has been escaping through and outta your box. Ribbed carpet excellent for a under-we spent many years(over25 now)utilizing our unders and keeping them outta the water is a must also. When submurged the garbage fills up and blonde sands adios you righteous oro puro. Moss- good to clean your boots on,thats about it for me. Pain in the arse cements and impacts way tooooo easy for me. Thats why we engineered the o/u tech to eliminate and simplyfy and increase fines retention. Different strokes for different folks BUT KEEP IT SIMPLE-the more garbage you pile on the more % you lose as NOTHING is 100%-tons a u 2 u 2 -john
