sub surface dredge Interact Reply Quote Report To Mod Last Posts Ignore User Global Ignore Whisper What size nozzle could a vw with a p1500 run as a sub surface dredge?

Re: sub surface dredge Interact Reply Quote Report To Mod Last Posts Ignore User Global Ignore Whisper 10" if it's legal, or a ten inch hose ringed to 8". Depends on the VW engine. 56HP no problem, but an old 40HP probably wouldn't pull so good. There are better engines available than the old VW's. Can't imagine anyone using one of those things nowadays.

Re: sub surface dredge Interact Reply Quote Report To Mod Last Posts Ignore User Global Ignore Whisper you would have no problem running a sub 12" if you build the right jet log you might get a 14" to work. i have a 60hp vw and the same pump and no problem running a sub 10" bill-cr

Re: sub surface dredge Interact Reply Quote Report To Mod Last Posts Ignore User Global Ignore Whisper Whichever size dredge you go with, the pump & eductor still have to be a matched set ... in other words, whether you are powering an 8 inch surface dredge, or a 10 inch Subbie, they would still use the same eductor (jet-log), because they are powered by the same engine & pump.

Re: sub surface dredge Interact Reply Quote Report To Mod Last Posts Ignore User Global Ignore Whisper Have you guys ever used a jet nozzle with a 4 inch check ball valve, for a shut off? That way you could kill the water supply for a plug up. Im looking at a 8 inch Scott

Re: sub surface dredge Interact Reply Quote Report To Mod Last Posts Ignore User Global Ignore Whisper Scott, I think the Schmidt Bazooka was the only successful, completely underwater 8" dredge, that would catch much more than small nuggets. It was very awkward and hard to handle and no longer in production. Trying to work with small gold totally underwater has always been a problem. Your V W is plenty of engine for most normal sized subbies.

Re: sub surface dredge Interact Reply Quote Report To Mod Last Posts Ignore User Global Ignore Whisper I was going to try Glens big yellow beast. With the extra hose Im hoping to clear a much larger area of overburden.

Re: sub surface dredge Interact Reply Quote Report To Mod Last Posts Ignore User Global Ignore Whisper Your VW should have no trouble with that since it was designed to use a VW as power. Problem is there is a lot of small gold in the overburden that you will just blow out the other end.

Re: sub surface dredge Interact Reply Quote Report To Mod Last Posts Ignore User Global Ignore Whisper What about a " fine gold screen/sump" built into the bottom floor of the sub, the sump screens and lifts the fines up to a small surface fine gold ( popandson ) surface sluice, The screen and sump could be placed at the rear of the sub box/tube, the bigger gold has already settled in the front riffles of the box/tube, ??. maybe a removable attachment fitted to a existing sub,??. screen could be on alot more angle then sub sluice/riffles to ensure "no" build up of rocks on the screen, ??. Run the sump jet ??. (4 -5 " ) off the big VW p1500, ??. :confused:.
