Glad to see your interest to build the best you can. Good video. The miner Mose should be at the top with a great over it. It if not feed to fast will grab a lot of the martial slow it down and let the gold drop out into the Mose. P.S Put thin carpet under the Mose so the gold won't wash down. I have run my dredge configured many ways. I have gold hog matts / Carpet and riffles and more. Avenge. Gold hog matts clean faster and less cons. Carpet and riffles. Little more gold BUT a lot to cons to clean out in the end. Most of the gold will be in the top 1/3 to 1/2 of almost any descent 48 '' long sluice. I have done test with 8' sluice and fine specks after half of the first sluice. Don't over think it. You can build one out of wood with just 1x2 boards as riffles and catch gold. Build what works for you and makes you fill best. Good luck.

I like the way you made it

pretty cool
