Homemade Portable Gold Mining Trommel

[TheJogdredge] has been testing out his new gold washing machines that he made at home. By running dirt laced with rocks through this trommel, gold and precious materials can be filtered out. A video of the process can be seen embedded below.

The rig — which is meant to be easily lugged around from site to site — is powered by a Honda GX120 motor. No plastic parts were used in the system to help make it more durable. But foregoing the use of plastic means that this guy is heavy. The rig weighs about 240 pounds dry, and 265 when soaking wet with a sluice box attached. The rubber tires allow for the machine to be maneuvered from place to place without much hassle.

Although the parts are described on the website, no how-to instructions for this specific device can be found online. This is probably due to the fact that [TheJogdredge] is trying to sell his products and make some money. Releasing the instructions on how to build your own would most likely cut into the potential profits of his design. Regardless of which, this is portable gold mining trommel and perfect for those looking to step up their gold mining and prospecting game. The real question on our minds is: can you get more gold for less effort this way, or through electronic junk mining?

  1. “Roughly, the rig weighs approximately 265 soaking wet.”

    “The rubber tires allow for the machine to be maneuvered from place to place without much hassle.”

    Uhh? It still weighs 265 pounds. Rubber tires help make it able to roll around but it still weighs 265 pounds.

    1. So drain the water, disconnect the sluice box, and you’re at a managable… 240 pounds… So like a heavy wheelbarrow? Shouldn’t be too hard, especially if you have an ATV to haul it with.

      1. Ever tried getting out to a gold site? I found it surprisingly difficult when I went. Lots of big rocks in the river bed. I would make the CG as low as I can, that way it doesn’t fall over easily and you don’t have to lift the paydirt up as high.

    1. See the ridges in the output chute? Gold dust gets trapped behind them because it’s too heavy for the flowing water to lift. Most other materials get washed away.

    2. Dirt with gold flecks goes in the first hopper, the spinning tube uses differential in mass to separates the valuable stuff from plain rocks, the valuable stuff goes down the water slide (the sluice) and the heavy stuff (which is usually metal) gets stuck in the bottom of the track (which used to be made from left over carpet, and after you picked the carpet clean of tiny gold pieces and flecks of gold for several weeks, you’d burn the carpet to get the gold dust out).

      1. That’s exactly what my father did except the burning part. Carpet was too expensive for his cheap butt. I still have most of his equipment, most of which was handmade.

      2. That is not how it works.

        The trommel works by screening the small stuff from the large stuff. A gold nugget, if it too big, will simply go right out the end into the pile of “waste.” Mass of the object really has nothing to do with it.

        IMHO, dry screening is faster and easier than wet. But, you then still have to run the dirt through a sluice anyway.

  2. Reliable you say? I have that exact same Honda engine on one of my air compressors. It has been dead for years. I think it is the low oil sender switch in it that is busted.

    1. So your failure to fix one minor fault for years means it’s an unreliable POS? Not sure I follow your logic.

      I used to work at a karting centre running a fleet of maybe 50 GX160’s, we removed the governors to let them rev a bit and those things took abuse day in, day out, for years. Probably put more miles on them than most people put on a car engine. One got hit so hard in a crash the block cracked and you could see the conrod going up & down, still ran fine.

    1. It’s not a hack, it’s just some guys invention that he will eventually market and sell to desperate men thinking they’ll strike it rich with this toy.

      And that’s where the money is in gold mining – selling stuff to the marks. The real pros don’t waste time with this stuff.

  3. Might even make enough to pay for the hearing protectors needed to work around the marginal muffler on that engine (yes Hondas are great, but still….)

  4. You varmints! Dat dere is gold I tell ya! It is in the value of the rocks taken to yer local quarry. I should know I am The roughest, toughest, mean ol’ hombre to ever jump a claim. I’ve ventured far and wide in my travels, be it by air, land or sea. I’ve been a pirate, a prospector and a gunslinger, to name but a few. North, south, east, and west, it seems no matter where destiny takes me, there he be, the thorn in my side … that same ol’ long eared, carrot crunchin’ rabbit … goes by the name-a-Bugs Bunny.

    Great Honry Toads, that rabbut can jump a claim. I’ll be taking my gold (that he painted…) and collectin’ my obama money!

  5. Why not upsize the engine and run the pump and the drum off the same power source? Is it that the water source is too far away?
