Gravity Dredging, Practice Makes Perfect
Вставка

- After learning about gravity dredging and running two test trials to check to see if this would work for us, we are going forward with this experiment. We have committed a weekend to running our gravity dredge to see if we could move enough material to get gold.

We wrapped the hose around a handtruck and duct taped the crap out of it. We wheeled it down the trail with a guy pulling from the front and another on a rope at the rear to keep it on the trail. It now lives in a job box on our claim so the only dragging now is up the creek to a new work area.
Excelente trabajo guerrero
Love the fact you can't hear a engine screaming at you!
Good job.!!
There's something called bernoulli's principle akin to the vacuum created by an open window in a moving car. I ponder a suction hose powered by a cone on a bottomless bucket into a pvc y for a prototype. The funnel is somehow secured in the rapids. No idea if it can be made to work. If somebody has input let me know please. Gravity dredging looks interesting but that hose is huge and you have only spots with a huge drop to work. Kudos on the gravity dredge.
if you are not using hose as a sluice, why not run straight hose? may be gold in hose riffles???
I guarantee you expelled most of your gold out the sluice, you had it too submerged in water, a mistake ALOT of people make, more water in the sluice equals less pressure, and thus, less vortex for the gold to drop out in. Try less water in the sluice with a bit steeper angle. there is a few good videos by howtodrillawell that will help better explain this, Good luck and happy hunting!
what size hose are you using? how much footage of hosing is good enough to operate? great advice on the floaters, Thanks!
can you tell me what kind of hose you used and where i can get it?
Hi.
Did taking the dips out of the pipe increase its effectiveness as a dredge?
Thank you for sharing.
very good nice set up
Hit the white water spots. That is a gold drop
What kind of hose is that please
What type of hose did you use? It looks like dredging suction hose and that must have been expensive!
Rick I used to work with a mark sharp. Any relation? Doesn't matter, just saying is all.
nice job guys ,john willard stop trash talking and show us your fekin go
