Gold Sucker Pump

Post  gray.nomad on Fri Mar 27, 2009 6:57 pm

Hi all,
If anyone here is interested to build his/her own "Gold-Sand Sucker" (see http://www.youtube.com/watch?v=FKDaGuK_cJA&feature=related), I designed and build my own pump and it works a treat. The plans are absolutely free for the asking. Smile
Just pm me.
My pump is a self cleaning double check-valve action, cheap to build and better then what you see in the movie.
Total cost app. $50.00.
Have a look at the YouTube movie first, then if it's of interest, email me.

See you up them thar hills

My own Gold N Sand Hand Dredge which I purchased this year to evaluate.

Technically this is a hand dredge. The video you linked to is the actual Gold N Sand model and the maker of this device assures me that there's a few illegal knock offs which 'don't work quite as well as the original'... more on that in a moment. The Gold N Sand is/was USD$99 and I purchased a Gold N Sand pump system from the US a couple months ago, expecting it to work nicely. Mechanically it appeared to be quite sound. But the system of leather valves and the distances involved between the valves and the outer nozzle meant that mine was not ideal for small Gold - which tends to fall back out before it makes it into the hose. Even some of the smaller gravel didn't make it into the hose. Part of the reason is that the Gold is too heavy for the distances involved (between components) and also the amount of suction produced is not strong enough. I ended up removing the lid from the bucket and placed it directly into my panning dish and weighed it down with a rock. Then I pumped directly into the pan but neither setup worked flawlessly. In fact I crushed the webbing between my thumb and forefinger at one stage... did it again too. So watch yourself if you use one. It did transport some sand and debris but the results for me were more satisfying with a modified yabby pump. If it was twice as powerful (suction wise) as the one I used it would be a winner. And the construction is actually quite tough. Several interchangeable heads with filter came with it as well (see picture).

The seller was straight forward, fast to ship (it arrived internationally in UNDER 5 days!) and took the time to explain to me why his components were designed to work well and would be long lasting. Unfortunately, I wasn't as happy with the results as I thought I would be. There is a "running in" time for the leather seals which expand in water and are superior to greased washer-system. But by the end of the tests I don't think it worked as effectively as I had hoped it would. I'll give it another test later to see if the valves have been broken in properly and work more efficiently.

Not sure you can produce and sell it here in Australia because the Gold N Sand is ALSO disctributed by several nominated dealers (according to the manufacturer) who will either report you for doing this to the Federal Police (the same squad that visits the local Sydney/Melboune markets looking for illegal, unlicenced knock offs) or find you personally and work you over for damging their livelihood. It seems to be a case of "Monkey See- Monkey Do" in the Prospecting community... and that's the way it was in the 1800's too. Make your own by all means but don't go selling these knock offs to the public by directing them to videos of the original product and then offering them your own under the guise of yours being "as good as the real one" (not that this is what you are doing... I'm just saying "be careful"). I can assure others that it will cost a LOT more than $50 to make one of these though. At least twice that if you look at the valve mechanism required in order to shift sand into the tube. I gather you didn't see the thread last week on violating overseas design patents in the Prospecting community?

Cheers,

Marco

hi marco,
i know a bloke that had the same problem, to give it
more suction he put some stiff rubber beneath the
leather so it was more firmer right out to the edges.
might help

Gold Sucker Pump

Post  gray.nomad on Wed Apr 01, 2009 7:54 pm

Hi Nero,

Please read my first post again.....
The plans for my pump are absolutely free, but for the asking for it.
I do not ask any money for it, I do not accept any donations for it, if anyone wants to have a "go " at me, bring it on....
My system is different then to the "gold and sand" pump that you have bought and which I referred to in my first post. Mine works similar, but better, due to a "almost" non-clogging and self cleaning check valve system.
I made several pumps, they work ok, if you're after flakey stuff.
The reason why I made those plans available is simply that I want to help others, if they want to build a good, reliable hand operated dredging system, 'cause that's what it is.
See you up them thar hills
Frank

Hi all,

Thanks to detrackozi I have come across "file Sharing". Thanks also, Clarrie, for the WA files.

Gold-N-Sand

Post  gold-n-sand on Tue Oct 27, 2009 5:55 am

Wow, I just came by this and I'm glad I did..what a great forum! My name is Red and I make the Gold-N-Sand hand dredge and am very interested in responding to any question that you may have regarding the hand pump. I have made these pumps for almost 2 years and have made some changes that seem to relate to some previous comments. The pump now comes with two plastic tension washers inside each leather cup which allowing them to swell tighter against the 2" wall tube. As the cups absorb water a swell, it may be necessary to remove one of these to allow for less friction. I've notices that the kits seem to cause most of the problem because the ABS plastic pipe that must be purchased elsewhere sometimes is inconsistent with what I get here in the States. I am embarrassed that I didn't think of this before but time has a way of slappin' sense to the brain. You can easily make these plastic washers by taking a lid and cutting them out with a 2" hole saw and placing 2 in each cup to start.

Another new design note: When using the pump it is quite easy to pull the plunger completely out of the tube causing some frustration and bad words. Please be patient and try to visualize a hand saw instead of a pump. This technique will create "muscle memory" and you will not fight the plunger anymore. Draw the plunger minimally at first until you are used to the length. Also, I bevel the inside edge of the tube now to make it easier to insert the plunger. Thank you all for your business and hope to continue a good relationship with you all.

Gold Sucker Pump

Post  gray.nomad on Sat Nov 21, 2009 6:41 am

Hi guys,
I had a few requests lately for the info of how to build your own gold sucker pump. To make it easy on all, here is the link to it.
http://www.4shared.com/get/124743104/896b0085/Pump_Instructions.html

Total costs app: $ 50.00 Aust. and 4-5 hours time in the shed.
The instructions are comprehensive, but if you get into any problems, I am happy to help, just PM me.
The self cleaning check valve system is my own "Inventions", which I am happy to share with all prospectors.
The instructions are FREE, as opposed to other plans (usually US) for similar things on the WWW.
The pump can also be used for other purposes, I also use mine for cleaning out the crap in my fish pond.

Best regards
Frank

Gday Frank and all Ive personally seen this invention and It is of great design and simplicity just 1 of GrayNomads inventions when I took Frank around to a little local spot he gave me another of his creations an external amp speaker which I have since used and even found a little .3grammer with just yesterday.Keep up the great work Frank Ill catch up with you soon and who knows what we might find >Cheers Dave

Hello Dave,
Thank you very much for showing me around and thanks for those kind words.
I am very happy that you could use the external speaker with success. I am certainly looking forward to
get some serious detecting done. Hopefully, my plans will come to fruition, in which case you will have some
more recruits for the CFA.

Thanks again and best regards
Frank

Yabby Pump mod.

Post  joe on Sun Dec 27, 2009 8:36 pm

Hi All,



I’m an amateur when it comes to prospecting; I’m also new to this forum and enjoyed reading your posts. Interested building or modifying my yabby pump to something of similar concept here.



Has any one of you built this pump I have found on YouTube?
