GoldiBox Fluid Sluice Box

Last crawled date: 4 years, 2 months ago

I've designed and tested about 13 different sluice boxes. This is the GoldiBox Fluid Stream Sluice and it's one of my favorites. It is a medium size fluid sluice box for gold prospecting. It is 22.5" in length. It comes complete with an inline classifier and printable indicator matting. The GoldiBox Fluid Sluice can process quite a bit of material and when you're done running, you are only left with heavies and concentrates (i.e. black sand & gold) in the trap.
This version is based on a Recon sluice I use to own but unfortunately, it got washed away. So instead of buying another, I designed this. Simple to set up and operate, this version recovers coarse gold as well as fine flour gold. It has been extensively tested for the past 3 years and works well. It can process about 4-5 buckets per hour depending on the type of material you're feeding it. For muddy or clay laden material, the classifier is very convenient as it allows the water flow to break up the material without washing it straight out the sluice. All gold pics are of gold that was recovered by the GoldiBox in Butte Creek. (Magalia, CA) - less than 2 miles from home.
The trap and the flare have integrated biscuit joints to join the sluice together. The joint requires epoxy. I recommend using Gorilla Glue Epoxy or some other 2 part epoxy when joining the pieces together. The Gorilla Glue 2 part epoxy has proven reliable and effective in the joints for the past 3+ years under heavy use.
There is a pocket (indentation) on the surface of the sluice to accept the indicator matting. The mat fits flush in the pocket and needs to be glued in place. I use a light coating of epoxy on the bottom of the mat but silicon would work just as well. Whatever waterproof adhesive you choose, you only need a little. Apply a nice smooth surface under the matting to avoid bumps. The indicator mat is not intended to be removed.
All parts are printed in PETG. The mat is printed in PLA but you could use any material. Black, dark blue, dark green and purple provide the best contrast for gold.
The classifier requires four M5 x 15 mm bolts which serve as the legs. There are four holes modeled in the classifier to accept the bolts.
All parts but the mat should be printed vertically in the following orientation:
1) TRAP - The end of the trap should be placed on the build surface so the joining end (to flare) is at the top of the print.
2) FLARE - The end of the flare should be placed on the build surface so the joining end (to trap) is at the top of the print.
3) CLASSIFIER - The classifier should be printed with the front wall on the build surface so the open end is at the top of the print.
4) MAT - The indicator matting should be printed flat on the build surface.
If you print this, please post a picture or video of your make. It will encourage me to release my other designs and to continue developing new ones.
Happy Prospecting!!!!
