Winter has really set in and I am looking foward spring as so I can get back up the river. I mainly detect now but cant seem to rid the bug of sucking up the paydirt once in a while. Thanks again Steve

Enters tube at a 15 degree angle 6in from the end. Eductor is 2in OD then tapers to 1 and 1/2 OD. Last 6in of eductor are cut on a taper until it runs out and welded in place. Eductor does not have to be 2in. some are 1and1/2in although 2in delivers more water. Overall length could be shortened to 30in. Get back if you don`t understand something...hard to describe.

I too enjoy designing and fabricating my own equipment, I am building it so that every thing/hoses,motor,nozzles,jet etc, can be carried all at one time. Sluice box has a 2ft slick plate, then a small drop riffle system followed by carpet and miners moss under #9 expanded metal, still going to add some riffles in case a big one rolls through, will be testing it out next weekend.

Have you seen this Nozzle, it has an extra little pipe on it with a turn on/shut off valve fitted. open the valve and you can divert some of the pressurised water flow into the gravel to break it up a bit, or create a little puddle on dry stuff to suck it up.

God, You`ve got some pretty impressive gear for this prospecting game. And at least 6 detectors. Must have cost a small fortune to acquire that lot! Heavy to lug around? Well,all credit to you in this venture, you deserve success!!! its good to see somebody as keen as you are, I wish you the very best. A bit different from in my day, when we had to make do with what was at hand,and even then, some of that wasn`t very efficient, plus there were no 4wd vehicles to get into the rough stuff, we walked for miles. I quite like your method of using a garden hose to distribute water from th pump, as it a bit more flexible to use than the nozzle that I came across whilst surfing the net. Cheers---Colin

Winter has a firm grip at the mo but I am heading up the river next week to help keep the fever at bay. Cheers for the ongoing input Steve

Impressive setup, I bet that lot sings along beautifully. I should have mentioned before, “No flies on you mate” you do things properly! I’m jealous. : ) I never had anything like that, but perseverance helped a lot. There’s heaps of others out there that should take a leaf out of your book. How did I know you had a few detectors? Lucky guess, I guess.(where’s the Gold bug 2.) Another guess is that your missus has auburn/red hair too ? Cheers---Colin, you take care too.
