Thanks RR, it's very close to what I was looking for... How goes the hunt for your guy's dredge?
Another update/change: I think I'm back to doing a over/under box again. I will be going a different route though. The more I study Dave McCrackin's Double Screen Classification system
» Double-screen Classification System in Dredging the more I'm convinced that this is the direction I need to go. The gold here in Idaho, err well where I dredge is all fine, so I'm thinking that's what I need to focus on. In the past I must of missed this video segment:
I went the 3 stage route on my 4" because I did not like the idea of having to clean the whole recovery system out just to check my values. I think I take his example and modify it to fit my needs.
Yesterday I had to work on my truck, shocks and idler arm replacement, then shop for more parts so only got to work a little on my dredge. Started on the last attempt of a heater.
