EXTEND HIGH BANKER SLUICE BOX??

[mumsituk]

Hi, anybody have advice on how to extend my box on my Gold Buddy high banker with 24" x 8" bottom sluice - or is this better idea to catch the very fine stuff? I thought maybe another 12" longer. And, yes I do classify cons and use a Blue Bowl later. Thak you in advance.

you could add a 12 inch slick plate before it gets to the riffels to help stratify the material.

Maybe I'll try that. Thanks RUSSAU

Why not just run a drop riffle riffle behind the highbanker like we do on my buddies Angu MacKirk dredge? It works great and we always find some gold in those riffles that the dredge lost.

good point!

Astro' I think you have the best Idea about running a Drop riffle after the highbanker sluice or Vortex matting
One thing to be careful of is water flow, you don't want it to be very fast and forceful.What size motor & pump
is your highbanker? You may have to tweek your water flow down a little If to much force you could blow your
fine gold right out the end of your sluice.If you are loosing gold slow down water flow or raise end of sluice. It
might be a good idea to run a see thru plastic damper This will help to make your gold lay down. Put damper at
head of vortex matting or plane rubber matting. I prefer vortex as it is the best you can get.
Lastly a magnetic bar at the top of your sluice to get all your magnetics out. I would like to hear how it has turned out.
Good luck (strech)

Strech is right! screening and water controll is the key to saving fine gold in any type of equipment!

Mumsituk I should have asked you first whether you are loosing any gold over the end of your
sluice ,If so how much-a lot or a few specks.This would definitley tell you If you should lengthen
out your sluice.Sorry Sterch

Sterch,
Don't know yet. Experienced in CA years ago, but new to the game in NY. Yes, New York. It is known that it some (and I mean little!) very fine gold in some areas - result of melted glacier "bring downs" from Canada. So I would think to catch the fines, I would extend sluice with miner's moss under a small and fine expanded metal.

Strech,
What do mean by "see through damper" and vortex?? Pardon my ignorance, but it's been 30 or so yrs.

clear plastic damper that attachs to the headend of your sluice and lays down over the 1st 12-18 inchs of your sluice. this damper will flaten your water and help remove bubbles, this will speed up the dropping out of fine gold.

Ressau,
Thanks. That makes absolute sense! Changed my mind for getting high banker. I ordered a 2" dredge with narrow sluice (6" X 36") by Treasure Emporium (demo model called "Jose Special"). I thought I'd put a punch plate for first foot or so, to classify entry material. Would I defeat purpose of the plastic damper by using both? or one ahead of the other?
When I dredged 25+ yrs. ago (Serria foothills, CA), my 3" Keene was basic - no damper, no punch plate, no expanded metal, etc. - just Hung. riffles + carpet. This is all new to me now! Let me be a real pain - could you describe the damper thickness (guess it can't be to thick/heavy) and a pic of it would be nice of you - man, am I pushing my luck!! If there is anything I can do for you, yell to me.

about .

the thickness needs tobe just thin/heavy enough to flatten the water (no bubbles,or wave forms)but still allow the rocks/gravels to move underneath the damper. if its to heavy/stiff, itll jam the rocks underneath it. this damper helps the retention of fine gold.
