Highbanker angles

[TheFossickingKid]

Hey guys just a quick question regarding Highbanker angles as some of you have seen the Highbanker that I have been making I'm going to be getting put together soon and the question is what angle should it be? Thanks.

It's a difficult question to answer. You should use an angle that works best for your highbanker and the material you're running though it. You want the catchment system to clear out the lighter material leaving the heavies behind but not to the point of flushing the gold out. The best way to figure this out is by trial and error so don't be afraid to make adjustments to your config as you go.

Alright nugget thanks will put some pics up late this arvo tonight.

Flat, the angle should be produced by varying the height of the front and back legs. Just be sure when making your leg support to offset the angle - better stability.

few inches of drop per foot mate, use this as a guide then you can always raise and lower front and back. alot of people use adjustable legs i used fixed legs but use stones etc to built up or down if required. good luck. by the way its always going to change with different sediment levels and mineral types

Okay guys thanks for this information. I'm at school now and about to go start working on the Highbanker I about half hour.this lesson will be hoping to get the strips riveted to the hopper box the sluice box will be getting expanded mesh cut and most likely get the leg hold bits made if you get what I'm talking about. Will keep you all updated very soon.

different angles are needed for different materials gold and gems act a little different I have found when chasing gems I have the banker nearly level to catch the little buggers found out the hard way

Okay right thanks Richie. The materials that I will be running is the material at hill end if some of you have seen that material you would know. So anyone know the angles.

Adjustable is how you want it.
From a steep angle to pretty well flat. For both your top & bottom sections.
If you're trying to break up clay, you'll want the top hopper to be fairly level so your material has time to wash more.
Cleaner gravels can use a steeper angle so the big stones slide out the back easily.
Bottom section rule of thumb is one inch per foot. So make it adjustable from level to say 3 inches per foot - gives you plenty of variables

Alright sounds good agman will get that down in the notes. Thanks

There is no right or wrong, any sluice with any configuration will catch gold, you are the one in control of how it operates though. I do however keep my bottom half at roughly 15 degrees, but I made my sluice without measuring, all by eye, so its a very rough 15. 3 inches per foot as mentioned above is probably a better guide to stick to though

Alright this is great AtomRat thanks very much.
