Mines is a 4" and that thing could suck on some dirt.. it uses 2 9hp high pressure pumps preferably diesel to put down the fuel cost. Where able is legal is the best way to go now in days because most streams are mined and in a lot of places most gold sits in the benches.. I just need to...

This is our homemade hydraulic elevator nozzle ..

Before you go all out i advise you to do a sampling program or have someone who have been in and out the river to better guide you. Normally here in the top part where the stream bed starts is where most larger nuggets are found at the end is where fines collect and inside bends while larger...

now in days there is veryy little virgen ground specialy in gold bearing areas.. having a understanding about if the area is heavyly mined is a good idea to know before hand because you dont want to be dredging others tailings... another thing is when you are not sure where a dredging cut was...

Wow thanks Reed. I have never seen that kind of scoop. I like the handle im the back something that i was thinking i could have placed in the design to have it towed by a crew.. Atleast to start with. That bucket seems used with be cattles or horses .? The scoop i was trying to design is...

This is exactly what im trying to work around..a motorized winch is something that produces a lot of strength and is very fuel efficiente. Having a properly having working bucket hoe could dig a large deep hole with enough cable.

The problem is we are planning on digging on a flat surface. .the place where we are trying to dig cant be dug by hand because it callapse. But there is about 30 plus feet to make it bedrock. The plan we had is to remove it with the Scraper bucket and hand dig the paylayer. If the...

No. What im trying to remove is just a clay material with some roots. I tried it with my first prototype bucket but it was not strong enough but my winch was working strong... Ima make it now with 1/2 slick plate now on the sides for it wont close in on itself. . But i know the winch...

Hello everyone.. I have been working on something to use to remove overburden with the use of two motorized winches. . A larger one to drag a scraper bucket and one to reverse the bucket to the new start possition. It should work something like a dragline but instead of carrying the...

i have not seen a large excavation made with these units as you see being done with Gravel pumps .. i have just seen shallow excavation made 8 feet and under. in my situation im trying to figure out an alternative to a gravel pump but i think a gravel pump is the way to go being able to lift...

About the same of a Vortex setup i believe.

This is exactly what i was looking forward to build but from the picture alone i could tell it takes a large amount of water to run from the jet inlet pipe and the suction pipe size. . it does looks simple to build. The throat isnt really nessesary since i have read some who made them without it.

Thanks for clearing that part for me..i would like to try to test one out. But i want something i could blast with a larger hose like a P180 and be able to have a elevator sucking up all the gravel. . Maybe ima need one larger then a 4" ... Does anyone have shared the plana behind the vortex...

To me i find it easier to make a metal one since i have more experience dealing with metal jet logs then in PVC one.

I have only seen the Vortex working in shallow ground . i could achieve that with just a normal dredge filling and unfilling a dredge hole. Im talking about using something that could shoot lots of gravel out of pit atleast 20 to 25 feet . The old times used hydraulic elevators that had a jet...

hello..have someone tried to build a hydraulic elevator ? how much water / pressure to run a 4" or a 6" ...

Hi Reed, I did get to build a clutch system and also a way to desengage to the drum from the motor. The reason you didnt get to see it is because the belt i got it too small and there wasnt any play in between it. i also didnt install the Pulley Bar because i needed a 5/8" screw to set it in...

Hello Everyone.. Dont let no one tell you you cant do it. i have build My Dredges and now My own Mechanical Winch. it could break in 3 pieces and be taking anywhere.

Hi Ratled & Reed .. Thanks for ya advices..im right now in a river that have been heavly mined and im trying to get into the more difficult part of the river to find more virgen ground. i have already started building the winch i have been trying to build a more stronger winch then the ones...

Sometimes you dont fall of the gold the gold just vanish out of plain sight. . Is pretty difficult looking for gold because of that. Then you have not another choice but to move on to a newer location which you dont know off.
