GoldiBox Fluid Sluice Box (Model #6) - Bazooka Style

thingiverse

This is model #6 from my GoldiBox series of sluice boxes and prospecting tools. This is a full sized Bazooka style fluid sluice box and is a workhorse. When I know I am going to process a lot of material, this is my go to sluice. This GoldiBox is 33.5 inches long and is 12.5 inches wide at the flare so it is capable of processing material extremely fast in medium to heavy flow. This GoldiBox model recovers fine gold and coarse gold. In the picture with the pan and heavies, you can see the amount of concentrates in the trap after running your unclassified material. The classifier is convenient for running clay and mud laden material and is also helpful when you do not have fast flow and want to run smaller material. The fluid box will boil in slower flow but only if you reduce the size of the material. That's when the classifier comes in handy. But if you have strong flow, just shovel away without the classifier. All the pictures in this posting showing gold were taken using this GoldiBox. The gold was recovered in Butte Creek (Magalia, CA), - just a few miles from home.

Print orientation & part quantities: Please refer to the image for correct model orientation on the build surface. Post Printing: The flare pieces and main body have integrated biscuit joints to join everything together. The joints require 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 All parts are printed in PETG. Black, dark blue, dark green and purple provide the best contrast for gold. The classifier requires (4) M5 x 25 mm bolts which serve as the legs. In the photos, you can see I used clear acrylic for the top shelf instead of "part 9-Top Shelf". I wanted to be able to see what was happening in the trap. This is optional. If you do not use acrylic, then print (1) "top shelf" piece and epoxy it in place. I sourced the acrylic from Home Depot. The end piece (wall) needs to be epoxied into the main body/trap. There is a groove in the trap to accept the rear wall. Install the pipes before epoxying the rear wall in the trap. The trap requires (3) x 8" pieces of 1/2" PVC with (3) couplers and (3) threaded end caps. The couplers are slip fit to threaded male nipple. The end caps are threaded to screw on the ends of the couplers. Only glue the couplers to the PVC. The end caps just screw on. This design allows for rapid cleaning of the pipes should they become clogged with debris from the inlet side (small stones, moss, etc). Simply unscrew the endcaps and wash through with water. Holes need to be drilled in the PVC pipes. I recommend 0.20 inches holes spaced 1.5 inches apart facing down in the trap. That seemed to create the best boil effect. Do not drill the holes through both sides of the pipe. Drill only one side of each pipe the entire length. The pipes are fitted into the openings of the main body rear wall and front wall with the drill holes facing down. Refer to the image showing the completed installation of the pipes. If you print this, please post a picture or video of your make. It will encourage me to continue developing new ones. Also, please click on the 'like' icon.
