River sluice ideas

[Pawny]

Hey guys and gals im thinking bout making myself a river sluice for those situations where theyre needed or i dont feel like setting up the highbanker. So what im thinkig of is a river sluice that doesnt require riffles. Not sure if it will work but im thinking of a river sluice that has a small section of expanded mesh at the start just on it own ad then half way down maybe some rubber matting with maybe some moss? Any idea and thoughts onthis would be great. Im trying to make it as light and portable as possible but also least complicated as well.

Cheers Justin

Simple hint mate,
Remember Bob's sluice at the week end. ??
2nd Hint. Fred Simms. LOL

First thing expanded bare on ally will help stratify but gold can easily be kicled back up into the flow. Expanded over ribbed matt is great if its fine enought like 2mm expanded over 2mm ribb but you need to run a gap around 3mm between rubber and expanded for it to work well. Addi g a few riffles will help clear it out quicker but is not requieed. I reckon just have a crack mate thats half the fun

From another forum with all respects.

The Fred Simms Sluice is quite a good little sluice and very portable.

A lot of people play around with modifications, usually to the matting.

The large Slick Plate area is what helps with separation of the heavies.

You do need to classify your wash down, and in doing this it can help teach the new chum to inspect the tailings of each sieve before discarding.

By sieving your wash down to 3/16 or 1/4 inch the sluice will clear much better and you can often get a surprise in the sieve in the way of gem stones which would otherwise just wash through the sluice

I would buy an angus mackirk. Just remember the wider you go the more flow you need. The less you classify the more flow and so forth.

Great is great and can work out very economic. Great suggestion ticks all the above boxes.

Thanks for the response guys so after a lil research it might jut be easier to buy somethig already setup and built. Ive heard of the angus mackirk and alot of people swear by them? I found one i think its callled the alaskan by angus mackirk it looks good a it meant to be an all rounder.

mate the AM sluice range are great i wouldn't think twice about buying any one of their sluices, in fact i use one for my cleanup system at home for fine gold.

divert the stream, fit monster concrete sluice to the bottom of the creek with a good set of gold traps, divert the creek back over your new super sluice...clean out once a year..

 

[Guest]

Here's my sluice for the year' each section is the best of the last few iv built plus added a few extras....

Still some dremmel work to do but I'll give it a run first'
By far easier to buy but I enjoy building crap.

 

[G0lddigg@]

nice setup mate, i like the forward classification system in a sluice, bet that makes things real easy

 

[Guest]

I like the idea of being able to scoop creek gravel directly into a sluice' hard to wash dirt/clay tumbles out the end, this way I can scrape about with the spade or hand rake as everything gets saturated holding it back until it breaks up.
Dragging nice looking rocks such as Quartz up on top for inspection is also a good idea.

I like the classifying screen .
But it inhibits the flow of water ... i dont like messing around with water flow. i stopped shoveling straight into my sluice when i seen gold getting pushed down when my water was getting interfeard with big rock/blockages/ putting your hand in....

 

[G0lddigg@]

I tried a section on an am sluice but it slowed flow too much but the above design looks much better at working the slurry.

 

[Guest]

I don't dump directly in front of the classifier' I pour above the water line and slowly push the gravel down bit at a time' plenty of water flows around the sides and there's a big step after the first section making the gravel stop and the water smooth out.

Clay can be crushed/squished through, I hate double handling with buckets seems pointless.

Also designed to set up off a rock wall and use the legs to speed up or lower flow

 

[Marked]

Love the legs idea - I have found my AM Alaskan tricky to set up off a rock wall; there is never two rocks within easy reach the same height to keep the bottom end steady. I reckon a leg attachment for that might be my next rainy day project.

 

[G0lddigg@]

by the way have you ahd a look in the for sale section.... theres a bazooka on there for $200 self classifying awesome units

 

[Guest]

I saw that! Thought about building one but for that price why bother'

 

[Marked]

Unless you have access to one to directly duplicate every dimension so that it works the same, I doubt the trial and error involved eould really be worth it.

 

[MJB]

I saw grant selling his and thought I wonder how they work. Any one got any ideas or pictures on the layout of whats in th box at the bottom. Surely it can't be too hard to duplicate
