Advice, building my first dredge Options

[jimmyrig]

Hello all,

Need a little input. I'm building my first dredge. I have a 10hp 3" trash pump, A52 sluice, 2 inflatable pontoons from a large one man fishing pontoon, I'm building a frame, I have a suction nozzle and hoses. help I need: What do I use or where do I get the flare, dampener flap, and do I need a jet nozzle on the flare since I have a suction nozzle already? What else am I missing...

Keep going; good discussion. Trommels have been on my mind lately after working Chris' claim's clay if you want to discuss the merits thereof as well.

I have been working on a trommel setup for a long time. Personally, the efficiency and ease of use of a trommel far outweighs a crash box type high banker setup. That being said, a floating dredge in the right setting is the ultimate in personal material movement. It would be cool if nothing else to have a floating trommel :)

Since my A52 already has a stand I am going to start this setup as a high banker to make sure this pump can move material properly. Also another question came up in my research. Keen says the A52 with dredge riffles can handle up to a 2.5" dredge. I have a 2" nozzle but my pump is a 3". Needless to say none of my scrapped up pieces match. Should I just go with a full 2" setup and scale down the pump outlets, or should I get 3" hoses and a new nozzle and use the A52 for now? I can't financially get a bigger sluice and buy a new nozzle and hoses. My 2" nozzle I purchased from gold n detectors and have never used it so maybe he will let me trade up.
