3d Printable - Stackable - Modular Gold Sluice System V2

Recommended Posts

OK, so this time around, I have made things a LOT easier to work with, and expandability is key here.  Sure, it's not huge, but for a portable system, this should work great.

The key thing here is that I wanted a system that could be printed with little to no waste material, and yet have the structure and strength to hold up for a long time.  This is what I have come up with so far.  This will likely be my last design for this version.  I'm only tweaking a few dimensions here, as well as making new modules that can be added to it.

 

Features:

  • Modules are 276mm long by 104mm wide, max height of 106mm
  • (virtually) unlimited stackability
  • Use modules in any order you want
  • Use whatever sluice mat you want (to a point)
  • Best used with a 5 gallon bucket (self-recirculating water system)

Current Modules:

  • Feed hopper
  • Mat tray
  • Bottom Support

 

Key note here is that those modules, even with the tilt, print FLAT on a printer, and unless something drastic changes, will require NO supports.  That means nothing to clean up after the print is done.  Pull it off the printer, and use it right away!

The cutaway view shows you how it currently operates.  I did away with the "G-Force" drop whatever that the Gold Cube has.  I wanted better flow, and didn't think that part was completely necessary.  Some of those angles might change by the time the final version rolls around.  I am still waiting on my four 200GPH water pumps so I can physically test flow rates.

I know this is still very small compared to a lot of the others that you can shovel hundreds of pounds a day into, but this is meant more for fine cleanup or to run pre-classified material through, although this should be able to do a bit of classifying on it's own.

Also, as I design more modules, I might include a couple modules that will spray wash and classify before sending down the smaller material to be run over the mats.

I would also like to design a sort of trommel as one of the modules.  Would have to be geared to run off of some water pressure, so I don't have to include a motor and all the electronics and extra building parts that come with it.  This is one part that would have to be made from metal, as anything printed would get destroyed very quickly, so I'm still contemplating this one.  Remember, this system isn't meant to drop boulders into.  I'd say you can safely feed in no larger than 8-mesh material.  Depending on water flow, you might get away with 4-mesh, but I wouldn't count on it.

More info coming as I get more work done, and get a chance to print some physical models.

OK, so I added a feed hopper that takes 4x 16mm ID (19mm OD) hoses running off of a couple of 12V submersible pumps.  You don't have to use all the feed holes in the hopper, but you can if you want.

I'm headed back to my other house tonight to get my big 3D printer.  These won't print on my smaller one that I have here.  Once I get them printed, I will set up a video, and test out water flow.  Should be self contained with a 5 gallon bucket, so it's recirculating.

If any of you have any ideas, suggestions, or possible changes/additions to the modules, let me know.  If you'd like to design one to fit the system, I'll forward you an STL of one of the pieces so you have something to work with.

      Hello,
      So I am a beginner and amateur, but interested in finding gold as well as old coins, old bullets from muskets etc, relics, etc with a metal detector in Sweden. I have many thoughts about this, which I hope you can help me with, so I would be very grateful.
      I list my thoughts and questions below.

      1. I was thinking about hearing what you think about the possibility of finding natural gold (gold grains, etc.) in Sweden in, for example, streams, etc., with a metal detector adapted to search for and find small gold grains?
      I found a website that has an article on it: http://www.detektorist.se/metalldetektor-guld/
      If I understand them correctly, they mean:
      - The gold you find in Sweden unlike, for example, the USA and other countries (where you can often find the whole gold nuggets, unlike in Sweden where you find mostly small gold grains if you are lucky?) Is too small for a metal detector to find or almost impossible. It needs to be at least 3 milimeters for a metal detector to found it and may only be a few cm below the ground.
      - And that gold is not flattened in Sweden, which makes it even more difficult to find.
      - That gold is most often found in mineralized soil, which makes it difficult for the metal detector to get real signals, distinguish gold from other metal, etc.
      With that in mind, do you think it's worth it? Or waste of money? Or do you think it is wasteful and almost impossible to find gold in Sweden with a metal detector even if it is adapted for it?
      I am also interested as I said to find old coins etc. Should I put down the idea of finding naturally gold in Sweden, and buy a cheaper but good detector that is more focused on old coins, old bullets from muskets etc, than one that is most focus on finding natural gold?
       

      2. Here I can buy in Sweden, "Professional metal detectors - metal seekers for prospectors looking for gold and minerals": https://www.guldstrom.se/sv/guld-mineralletning
      The metal detectors for seeking gold is:
      - Minelab Equinox 800
      - Minelab Gold Monster 1000
      - Minelab GPX 4500
      - Minelab SCD 2300 Guld detektor
      - Garrett ATX
      - Minelab X-Terra 705
      - XP ORX metalldetektor
      - Gold Rush tour 2020 Australia
      - Minelab GPZ 7000 Gold detector
      - Minelab GPX 5000
      - Fisher Gold Bug 2
      - Garrett AT Gold

      Would you recommend any of these?

      3. I did send the swedish company an email and they answered:

      "Without a doubt, the best detector right now is the Minelab Gold Monster 1000 so this is the one to look for if you want to look for gold in Sweden.
      It also manages to find mineralized stones and it can differentiate between mineralized stones and solid metal.
      It is also excellent for exploring in streams and streams and the search coil is waterproof so it works great. The GM 1000 automatically adjusts itself so there are no knobs or buttons to turn on but just "whip and drive".
      You can find a really small gold grain -1mm in about 5 cm
      A larger gold grain of 3mm can be found in 10 cm
      A large gold grain of 4mm can be found in about 15 cm"
       
      If it is true on detektoristen.se that a gold grain must be 3 mm in Sweden, then the Minelab Gold Monster 1000 finds a gold grain of 1mm of 5 cm, 3 mm of 10 cm etc., so it does not seem to be a problem? In addition, it seems to be adapted to find gold in mineralized soil.
      So do you think it can work well to find gold in Sweden with a metal detector like Minelab Gold Monster 1000, or what do you think?
       
      Thank you very much.

      Since we cannot get out into the field to prospect properly right now, figured we'd share with you a piece of equipment we use for testing in our garage and also in the field for hard to get to places. Its great for hiking in, testing several locations and then coming back with larger equipment!!

      Hope everyone is well, stay safe!

      Along with working on the house this winter, I finally got around to drawing-up, and building a new driver for my shaker table.
      I really like Wilfley's designs, and wanted my driver to have the same adjustments as his. Working about 4 hours/day, it took me about 2 months to get it drawn and built, along with a few modifications that arose during the build. Finally finished yesterday, and made a video. I'm still polishing up the plans, and will probably have to disassemble it to take pics for the build instructions etc. I'll be selling the plans and, instructions at some point this spring, for the DIY clan.

      Hey Guys,
      One day I didn;t have my pan so I used my shovel to pan, and it worked quite good.

      I'm not much of a sluicer. I'd rater be looking for nuggets with my detector. I like gold I can pick up with my fingers lol. My wife bought a small Keene sluice box several years ago and we set up a recirculating system at home where we could run some dirt at our leisure just for fun. I never really liked my home made set up. Although it worked it was slow..It was like a mini high banker made with stuff I got at the local hardware store. I  was wanting something more efficient. In my search I found Gold Fox USA. There is also an Australian version that is the same company with a dealer who distributes for them in Oz. 
      I wont go into a lot of boring detail...you can go to their web site and face book page or youtube for that...However I would like to say that so far I am very happy with this little set up. I can run unclassified material through this sluice extremely fast. The trommel is five inches in diameter. I've only used it three times so far and time will tell on how durable it is but it seems to be very well built. The company has many different sizes and options available. They are fast and get the product to you when they say they will. If you have a question Kelly the owner will get on the phone and answer it for you. 
      The Lil Monster Deluxe comes with a 12v 2000 GPH pump. You supply your own power. I am using a RV deep cycle battery that I had laying around. I also bought a 700 GPH 12v pump and am using the two pumps together. The reason being is the material I am running is mostly clay and I wanted more water to help break it down. The only thing you have to watch is that the jets that supply the trommel will get plugged with organic material. They are easy to clean. In fact if you turn off the water supply to the hopper so it feeds the jets only...the water pressure is enough to flush them clean most of the time.  Give them a look.
