DIY gold mining equipment lets you work more ground for the price of a few trips to the hardware store, and honestly some homemade gear outperforms the budget commercial stuff because you build it for the exact water you’re working.
I’ve built most of these rigs myself over the years, broken a few, and fixed the designs. This is the practical version: what to build, what it costs you in effort, and the mistakes that cost me gold before I sorted them out.
TL;DR
- Start with a homemade pan and sluice. Both are simple builds and together they’ll recover most of the gold in a creek.
- Riffle spacing is everything. On a sluice, space riffles about their own height apart, roughly 1 to 1.5 inches, so each one rolls the water into a trap.
- Set sluice slope near 1 inch of drop per foot. Too steep and gold blows out the bottom, too flat and it packs with sand.
- A highbanker is just a sluice with a pump. Build the sluice first, add the pump and hopper later.
- Check the law before you build a dredge. Suction dredging is banned or permit-only on many waters, so the build is the easy part.
- Miner’s moss under expanded metal beats bare riffles. The carpet traps the fine gold the riffles bounce loose.
Make your own gold pan
The pan is the simplest piece of DIY gold mining equipment, and a homemade one will get you through a day if your store-bought pan cracks in the field. All you really need is a shallow, wide container with a flat bottom.
A plastic dishpan or a metal pie tin both work. Plastic is better because you can cut riffles into it easily and it won’t rust, but a pie tin does the job in a pinch.
The build is short. Cut or file two or three shallow riffles, about half an inch of relief, along one side of the pan, spaced roughly an inch apart, and those ridges catch the gold when you swirl toward them.
Tips for using your DIY pan
A homemade pan usually has a slicker surface than a molded commercial one, so break it in. Rough up the inside with sandpaper to kill the shine and let the gold grab instead of sliding.
Work the pan low and slow underwater, tipping just enough to wash the light sand over the lip while the riffle side stays deep. If you see color leaving the pan, you’re tipping too hard.
Build your own hand-fed sluice box
The sluice is where DIY gold mining equipment starts paying for the effort, because it processes buckets of material while a pan does spoonfuls. A hand-fed sluice sits in the current and you shovel classified gravel into the top while the water carries the light stuff away.
The body is simple: a channel about 36 to 48 inches long and 8 to 10 inches wide with sides 4 to 5 inches tall. Aluminum flashing, a length of vinyl gutter, or a wooden box lined with pond liner all work as the base.
The riffles are the part that catches gold, so build them right. Aluminum angle stock cut into cross pieces makes solid riffles, and under them you lay a strip of miner’s moss or ribbed rubber matting to trap the fine gold that tumbles past the riffle faces.
| Sluice spec | Target | Why it matters |
|---|---|---|
| Length | 36 to 48 in | Enough run for gold to settle without packing |
| Width | 8 to 10 in | Matches a comfortable one-person feed rate |
| Slope | ~1 in drop per foot | Fast enough to clear sand, slow enough to hold gold |
| Riffle spacing | 1 to 1.5 in | Each riffle rolls water into a trapping vortex |
| Water speed | Fast walking pace | Classic field test, no meter needed |
Step-by-step build
- Cut the channel. Form your base into a U-shape, or line a wooden box, giving it smooth sides so material flows without snagging.
- Lay the matting. Cut miner’s moss or ribbed rubber to fit the floor and hold it in place, this is your fine-gold layer.
- Add expanded metal. A sheet of expanded metal over the matting creates turbulence that drops gold into the moss below.
- Fit the riffles. Space aluminum angle cross pieces 1 to 1.5 inches apart over the metal, angled slightly downstream so they don’t pack.
- Set the slope. In the creek, prop the sluice until water runs a fast walking pace and shows a gentle boil behind each riffle.
- Test with lead shot. Drop a few pieces of lead shot in the top, if they hang up in the first third of the box, your gold will too.
Check the sluice every twenty minutes. If sand builds up and buries the riffles, they stop catching, so pull it, rinse the concentrate into a bucket, and reset.
The materials list stays short. You’ll want your channel stock, a strip of miner’s moss or ribbed matting, a sheet of expanded metal, a length of aluminum angle for riffles, and stainless screws or rivets to hold it all together. Skip anything that rusts, because iron staining in your sluice makes it harder to spot gold in the concentrate.
One field lesson that cost me gold early on: classify before you feed. If you shovel raw gravel into a sluice, the big rocks tumble down the channel and knock gold loose from the riffles as they go. Screen everything through a 1/2-inch classifier first, and your recovery jumps noticeably.
Watch the head of the sluice too. The first few riffles do most of the work, so if you see them staying clean while sand packs the lower end, your slope is a touch too flat and the box is choking. Raise the tail an inch and watch the flow even out.
Design and build your own gold dredge
A dredge vacuums streambed gravel up through a suction hose and runs it across a floating sluice, which lets you work underwater ground you can’t reach by hand. It’s the most productive DIY gold mining equipment on this list and also the most legally loaded.
Before anything else, know the law. Suction dredging is banned outright in some states, permit-only in others, and restricted by season on many waters to protect fish, so a homemade dredge you can’t legally run is just a heavy raft.
Designing your dredge
The core is a suction system: a water pump feeds a jet that creates suction in the hose, pulling gravel and water up into the sluice. Match the hose diameter to your pump, a 2-inch dredge is a sensible DIY size, since bigger systems need serious pump power and get heavy fast.
The sluice on a dredge works like any other, so the riffle and matting rules from the section above apply. The difference is that it floats, usually on a pair of pontoons made from sealed pipe or foam, with the pump and sluice mounted on top.
Building it
- Build the flotation. Two sealed pontoons, spaced for stability, carry the sluice and pump above the water line.
- Mount the pump and jet. The pump pressurizes water to the jet, which is what actually creates the suction in the hose.
- Rig the suction hose. Connect the hose to the jet and to the sluice head, keeping bends gentle so rocks don’t jam.
- Set the sluice. Level it on the floats with a slight downstream tilt, matted and riffled like a hand-fed box.
Even where it’s legal, dredge only what you’re permitted to and never disturb spawning beds. The hobby stays open because prospectors respect the rules, and one careless operator can get a whole stretch of river closed.

Plans to build your own dry washer
When there’s no water, a dry washer is your recovery tool, and it’s one of the more satisfying DIY gold mining equipment builds. Instead of water, it uses moving air to lift the light material off while the heavy gold settles into a riffle tray.
The heart of it is a bellows or a small blower that pushes air up through a cloth-bottomed riffle box. The material has to be bone dry to work, so screen it and let it sit in the sun if it’s holding any moisture.
| Dry washer part | DIY material | Function |
|---|---|---|
| Riffle tray | Plywood box with cross riffles | Traps gold as air fluffs the load |
| Air cloth | Tight canvas or cotton drill | Lets air through, holds fine material above |
| Bellows | Plywood and leather or vinyl | Pumps air up through the cloth |
| Frame | 2×2 lumber | Sets the tray at a shallow downhill angle |
Troubleshooting and tuning
If you’re losing gold out the bottom, your air is too strong or your tray too steep, so ease off the bellows or flatten the angle. If nothing moves and the load just sits, you need more air or drier material.
Run a known amount of fine lead or a few tiny gold pieces through as a test, then check the tray. Dialing in a dry washer is trial and error, and every batch of ground behaves a little differently.
The air cloth is the part people get wrong. It has to be tight enough to hold the material above it but porous enough to let a steady stream of air puff through, and a tired old bedsheet won’t do it. Cotton drill or a good canvas gives you the even flow you want, and if you see the cloth billowing in one spot and dead in another, your air isn’t distributing and gold will escape through the slack section.
Feed a dry washer slowly. It’s tempting to shovel it full, but a thin, steady feed lets the air work each grain, while a heavy dump smothers the cloth and buries gold before the air can lift the waste off. Patience here is the difference between a full riffle tray and an empty one.
Build your own gold highbanker
A highbanker is a sluice with a hopper and a pump, so you can work gold-bearing dirt away from the creek by pumping water up to it. If you’ve already built a sluice, you’re most of the way there.
Add a hopper at the top, which is a bin with a spray bar that washes your shoveled dirt through a classifier screen before it hits the sluice. The pump pulls creek water and feeds both the spray bar and the sluice flow.
- Hopper: A sheet-metal or plastic bin angled so material slides down onto the classifier screen.
- Spray bar: A capped pipe drilled with small holes, fed by the pump, that breaks up clay and washes fines through.
- Classifier screen: Expanded metal or hardware cloth that drops the fines into the sluice and sheds the oversize rocks off the side.
- Pump: A small gas or 12-volt pump sized to keep steady flow down the sluice without flooding it.
The highbanker’s advantage is that it frees you from the water’s edge, so you can dig a rich bench or an old bank and haul buckets to the machine instead of only working what sits in the current.
Build your own gold shaker table
A shaker table is fine-gold finishing equipment. It uses a slightly tilted, riffled deck that vibrates, and the combination of shake, water flow, and gravity fans your concentrate out into a stripe of gold you can pick clean.
This is an advanced DIY build because the motion has to be right: a fast, short stroke along the deck’s length, driven by an offset weight on a small motor. Too violent and it throws everything, too gentle and nothing separates.
| Commercial table | DIY shaker table |
|---|---|
| Precision-tuned stroke and frequency | Offset-weight motor, tuned by trial |
| Machined riffle deck | Glued or routed riffles on smooth board |
| Higher cost, plug and play | Low cost, needs patient tuning |
| Consistent fine recovery | Good recovery once dialed in |
For most weekend prospectors a shaker table is overkill, but if you’re processing a lot of black-sand concentrate and tired of losing flour gold, a homemade one recovers what a pan can’t.
The deck angle matters as much as the shake. You run a slight tilt in two directions at once, a gentle downhill for the water and a slight cross-slope so the vibration walks the heavy gold across the deck to one edge. Get those two angles balanced and you’ll watch a clean band of gold form along the low side while the black sand rides off the end.
A wiper motor from a junked car makes a serviceable drive with an offset weight bolted to the shaft, and a variable speed controller lets you tune the stroke without rebuilding anything. Start slow and bring the speed up until you see the concentrate fan out into distinct bands, then leave it there.
Make your own hand-powered rock crusher
If you’re working hard-rock gold locked in quartz, you need to crush the ore before you can recover the gold. A hand-powered crusher breaks the rock down to a sand you can then pan or run through a sluice.
The simplest version is a heavy steel pipe and a matching steel rod used as a pestle inside a thick-walled pipe mortar. You drop chunks of quartz in and pound them down to grit, screening out the fines as you go.
- Pipe mortar and pestle: Cheap, effective for small batches, hard on the arms.
- Lever-arm crusher: A hinged steel jaw you pull down over a plate, better for volume.
- Screen as you crush: Run crushed material through a fine classifier and re-crush the oversize so you don’t over-grind and lose gold to dust.
Crush outdoors and wear eye protection, because rock chips fly. And crush only ore you’re sure carries gold, since pounding barren quartz is a lot of sweat for nothing.
Build your own gold rocker box
A rocker box, or cradle, is old technology that still works, and it’s a great DIY gold mining equipment build for ground with limited water. You rock it side to side while ladling water and dirt in, and the motion plus the flow drops gold into a riffle tray below a screen.
It uses far less water than a sluice, which makes it ideal for a small seep or a creek that’s low. The build is a box on curved rockers, a top screen tray, an apron of cloth to catch the first fines, and a riffled bottom.
The rocking is the skill. A steady, moderate rock keeps material moving and settling, while jerky motion bounces gold out, so find a rhythm and hold it.

Putting your homemade kit to work
Building your own gear teaches you how gold actually behaves, because when you set your own riffle spacing and watch what it catches, you learn recovery in a way no store-bought box teaches. Start with a pan and a hand-fed sluice, get those working, then add a highbanker or dry washer as your ground demands.
Build simple, test with lead shot, and tune in the field until the gold stays put. Do that and a weekend of hardware-store parts turns into a full recovery system, which is the whole point of good DIY gold mining equipment.
Frequently Asked Questions – DIY Gold Mining Equipment
What DIY gold mining equipment should I build first?
Start with a homemade pan and a hand-fed sluice box. The pan gets you finding gold immediately, and the sluice lets you process far more material, so together they cover most creek prospecting before you build anything fancier.
How do I set the slope on a homemade sluice?
Aim for about 1 inch of drop per foot of length. In the water, adjust until the flow runs at a fast walking pace with a gentle boil behind each riffle, then confirm it holds gold by dropping in lead shot and checking that it hangs up in the first third.
What should I use for riffles and matting?
Aluminum angle stock makes solid riffles, and under them lay miner’s moss or ribbed rubber matting to trap the fine gold that tumbles past. A sheet of expanded metal between the two adds turbulence that drops more gold into the matting.
Is it legal to build and use a suction dredge?
It depends entirely on your state and water. Suction dredging is banned in some places, permit-only in others, and often restricted by season, so check current regulations before you build one, because the machine is useless where you can’t legally run it.
How does a dry washer recover gold without water?
It uses air from a bellows or blower pushed up through a cloth-bottomed riffle tray. The air fluffs the dry material so the light stuff blows off while heavy gold settles into the riffles, which makes it the go-to tool for desert ground.
What is a highbanker and how is it different from a sluice?
A highbanker is a sluice with a hopper and a pump added, so instead of only working material in the current, you shovel dirt into the hopper and the pump feeds creek water through it. That lets you work rich banks and benches away from the water’s edge.
Do I need a rock crusher for gold prospecting?
Only if you’re working hard-rock gold locked inside quartz. For placer gold in creeks and rivers you don’t need one, but if you’re chasing vein gold you’ll need to crush the ore to a sand before you can recover the gold by panning or sluicing.
Is homemade equipment as good as store-bought?
For pans, sluices, and dry washers, a well-built homemade rig performs right alongside budget commercial gear, and you can tune it to your exact water. Precision equipment like shaker tables is harder to match at home, but even those work well once you dial in the motion.
