  1. Just finished this project, figured somebody might like it around here.
  2. This is a 3D printed blue bowl version 1, it worked amazing for doing my last big clean up and sucked the sand away very quickly. I didn’t want to pay an arm and a leg so I built my own, leave an e-mail if you want the file. The whole project cost me less than 30 bucks or so. Parts: -172 GPH Pump -3/8 Tubing -On/Off Valve -12 #10-24x1in Screws -9 #10 Washers -Rectangle Tub -Small Bucket -Printed Parts
  3. I have been working on this for a couple weeks. It's a collapsible, customizable, self-contained, super light, 3D printed sluice box! I know there are other folding sluice boxes, but none of them actually fit in a backpack, or are light enough to carry in one hand. This solution would be EXTREMELY helpful! I'm on my phone trying this, so when I get to my laptop, I'll write in a bit more. So I'm currently in the CAD stage. I have a guy that does 3D printing for me, and his machine is limited to 12"x12"x15" so I might have to shrink the size of the project down to fit, as I don't have access to, or can even afford, a larger 3D printer. I have this up on Patreon to attempt to raise some funding to start getting prototypes printed, and boost this project towards the finish line!

  4. Does any place still make and sell the rubber Knudsen bowl liner? Google seems to just lead to a bunch of spam pages. I acquired an old bowl and the previous owner thought there was a store in Reno that made or sold them but I haven't had any luck locating said store. Also semi-related I am rebuilding an old jig, never used one before, and I was wondering what people use for shot? Do you just buy steel shot in bulk like from an ammo place or is there something cheaper and better to use specific to jigs? I see tungsten shot available for jigs but it's the same density as gold more or less so I'm having trouble seeing how that would work, especially if I want to save the black sands too. I'm curious what people use here?
  5. My sister ran into a fossiker when out camping who was having an issue with tiny shot while finish panning. He was sucking the shot into his snuffer bottle when trying to collect the gold. Any suggestions? I have a feeling he's not the first person to be annoyed by this.
  6. I ran 2 Ozt of my -50 mesh, black sand concentrate through the Blue Bowl. It came out to .5 gram. This was 2 oz dry concentrate off the top of the container, I suspect the bottom my be richer after all the jarring around for the past 2 weeks. I'll send the Blue Bowl tailings and about a couple lbs of concentrates to Rege in PA to see what his Miller Table can do. If I could fill the back of my truck with this stuff it might be worth something, but as it stands not really a game changer. Still waiting on Rokon parts, then back to Gold Country. I've got a new plan, of course. 118 degrees here in Sunny Yuma tomorrow, but it's a dry heat. Yeah great!
  7. I tripped over this extensive article, available as a free download. Here is the abstract: The article sets out to clarify the special character of the North American gold pan and why it remains so popular – in spite of widespread dissatisfaction and many modifications and innovations. The North American pan is distinctive in being circular with a flattish floor ringed by an outwardly sloping wall. Its identity is confused by over-use of the terms 'pan' and 'panning'. The North American pan gyrates in a distinctive orbital motion driven by both hands of the panner. Although many other motions are resorted to (tapping, to-and-fro, tilting, and tick-tock), it is the orbital motion and flattish floor that together distinguish the pan from most other hand-held gravitational devices. In spite of its enduring popularity, no scientific tests have been published on the North American gold pan or for any of the innovations covered by 30 US patents awarded since 1861. It remains unclear if the North American gold pan is more efficient at recovering fine gold and flat gold than is a lotok, batea, dulang, ninja bowl, grizzly pan, mat, bucket or any other sort of hand-driven gravitational device. Some innovations are long-forgotten but merit attention. For instance, bars to keep the panners hand clear of the water, cables to hold large heavy pans, and several pans designed for panning without any water. Traditionally the North American gold pan was a combined digging and washing device, but today most models are not designed for digging and require a spade to be used.

  8. Check out my new setup for those remote areas where gas powered engins aint allowed
  9. OK I am new to gold panning but I want to purchase one so I can do some sampling around my property have searched the web for what would be best for a beginner there are so many different types on the internet that for a beginner gold panner it is pretty confusing what does everyone suggest for a beginner at panning I know panning is not easy at first and there is a technique to it its a learning process as everything is thats new to someone just looking for suggestions I figure a gold pan would be the easiest way to sample and see if there is gold here and the cheapest to start
  10. Has anyone tried one of these? Looks like a versatile piece of kit! I'm wondering what kind of run time you would get out of the electric pumps on say a 29 series deep cycle battery... https://keeneeng.com/mini-max-power-sluice/
  11. Hello, my first post. I purchased a deceased prospectors never used, no brand name, no manual spiral wheel recovery system (and other goods from the son). I can add that it came in a Rubbermaid protective ultility case marked "ActionPacker", is about two feet tall when assembled on a frame type stand with control panel.
  12. I'm looking to get a plunger style magnet for removing black sands from concentrates when finish panning. I've seen a couple which are labeled 8 lb and 16 lb respectively. Often bigger/faster/stronger means better, but not always. Any suggestions? Does the choice matter if the material is dry (as in bone dry) or wet (as in submersed in water)?
  13. How she look ? Dose this look like my punch screens will work great and giv the material more time to wash? Giv me poiters to please!!
  14. Hi Everyone Im trying to find Angus Mckirk sluice boxes on the west coast, has anybody got any ideas who sells the and where to find them.Even a few second hand ones will do Thanks
  15. So its puzzled me why panning classifiers are solely made for gold prospecting.Surely the manufacturers must be going out of business to make these items solely for the prospecting industry.Well this is not the case.I did some in depth investigation and spoke to a friend of mine in the plastics industry in China and showed him a pic of a classifier.What he came back to me with was quite interesting. Classifiers are actually made for the pyrotechnic/firework industry hence there manufacture origin in China.Kaboom and off it goes.They are used for milling black powder and other pyro ingredients.So if you want a set of classifiers and don't want to pay $24 a piece, then check out a pyro supplies store on the internet and you will be pretty surprised when the exact same classifiers /screens we purchase for prospecting cost around $12 a piece or cheaper.
  16. Ok, I'm a newb, and maybe a bit impressionable, but this really caught my attention. It's a long video by Doc of Gold Hog, but if you jump to about 20:00 you'll just see it in action to see for yourself. It's essentially a small short sluice that is hand operated. He processes a bucket in less time that it took me to do one pan (first day of panning). I figure this is a good way to run some material quickly, without the sluice. I'm just beginning and hope this isn't a hoax, but it sure looks to make a lot of sense. Maybe someday I'll have a dredge or high banker, but this sure beats the pan for concentrating and suits my budget. Hope you enjoy the vid as much as I did!
  17. Mods to try to catch some fine gold... Cut box down to 3', added ribbed mat and punchplate. built a new inlet. Will try it out this weekend.....
  18. I understand that there are multiple reasons for panning especially when you include professionals all the way to occasional, recreational prospectors. I'm definitely near the right end of this spectrum, but I'd like to get better, faster, more efficient. To be specific, I want to find all the gold in my bucket, and I'm not trying to make a threshold cut at return per time spent. Here are some questions I have: 1) Does classification help enough to make it worthwhile to buy, carry, store one or more in the first place? (If 'no' then I guess the rest of these questions are unnecessary.) 2) What sizes should one use? I know there is an array of sizes, but how many of those are useful? 3) Do you stack multiple sizes in one operation? 4) Do you still investigate the materials that the classifier rejects as too large? For example, with the wire mesh types do you dump the contents onto a clean, metal free area and run a detector over them to make sure there isn't a nice size chunk of the magic metal in your rejects? 5) I know the GPAA sells a set of screens that you swap in/out of a single housing. Is that the best direction to go if you are going to use multiple sizes? If I've missed any important points, please enlighten me on those as well. Thanks in advance for your answers.
  19. Hi Folks, say you hypothetically had a fair amount of crushed ore to process, and due to the amount of mustard gold in quantities worth recovering, what would you recommend and why? Water can be a problem so recirculating would be good, portability is a big want, will be using mercury and a retort due to the mustard gold. Open to suggestions. Many thanks, Steve
  20. This is not exactly new since it was announced last October, but I was wondering if anyone has seen or used these yet? The new Garrett 14" gold pan has a asymmetric design and fixes one of my pet peeves, which was the small bottom area. The Garrett gold panning kits now include these new pans. Here is the new pan next to the old design for comparison...
  21. On a side note Steve, I bought my first sluice, a Keene A52 hand sluice, from AMDS back in 2010 when on my first and so far only trip to Anchorage. You built an awesome store, and the staff were super friendly and helpful. Definetly a good reason to go back there, once the exchange rate improves. Cheers! It's now the secondary recovery section on my wash plant setup.
  22. I'm wanting to recover CW Bullets faster and easier from the cracks, pockets and holes on the river beds. I'm wanting to build it out of plastic as not to interfere with the detector. It will have different sized and shaped tips depending on the size of cracks if needed. This would be an intermittent pump just for bullet extraction. It will have a longer wand that would enable me to suck lead standing in 4 feet of water. I would build a simple catch area for the outflow. It looks like Keene's smallest pump is 100 GPM/6000 GPH for their 2 inch model. I am looking at a 12 volt system and have my eyes on the 4000 GPH Johnson Bilge pump. Now my question is do you think I can build an electric dredge that can suck big lead to the surface? Any and all ideas are welcome such as size, nozzle design etc....
  23. Quite often l have seen detectorists arrive at a new spot full of enthusiam and upon arrival jump out of the car, grab their detector and race off hurrying here and there like a headless chook swinging aimlessly in their excitement to find that first elusive bit of gold. Only to be dissapointed at the lack of gold finds and quickly ready to write the area off and move on. I speak from experience because l was one of those. However several of those spots kept calling me back. And when I did return it was with a contolled enthusiam. Instead of jumping out of the car and racing around I took the time to look about and read the ground. I took the time to get the detector running smoothly and most importantly I took the time to carefully detect the area I had chosen, thouroughly working the area in a unhurried manner. And on most occasions I was rewarded with gold. Yes gold from an area I was too quick to write off initially because I was in too much of a hurry to properly access the potential that was right in front of my nose. So all l can say is slow down, plan you attack and have patience and work the area properly and don't be too quick to write a spot off or you will leave it behind.
  24. Just was wondering if you nugget hunters find fine gold/flakes in the same dirt you find gold nuggets in? Do you go back and drywash/highbank those areas? Just curious. -Tom
