I have the bucket grizzly and have already thought of setting it up like this.

It does seem very expensive though.

Bucket Grizzly $59
Sluice approx $125
Stand $40

This does not even come close to $299. If anything you should be getting a discount for buying the package. $199 would be a fair price.

Edit: WOW did anyone see the price of the sluice and stand alone below the first green machine.

I will talk to Angus about this.

Shay,

See if you can carry the individual parts, I wouldn't mind getting the grizzly and highbanker mount for the AU Trap I have.

Thanks for the info, I will go with my own plan and make one for the AU Trap. I have everything to bend some plastic to the proper size and shape. Now I just need to get the grizzly. Sounds like a trip to Shay's sometime in the future. I might be able to use a 5 gal bucket; heat it up and spread out the sides to fit the trap.

No need to do all that to mount the grizzly... HDF or High density fiberboard coated in waterresistant sealant works great. just make the template after you have the buckect grizzly the whole idea is just to make a plank that holds the grizzly, 5/8" hdf sheet from Home depot should work great. long enough to fit the top and mount sideways like the pic's so the 1/2 tailings go off into the water. use small c-clamps to hold in place.
cheap and easy. i think, please correct me if wrong... Twisted Evil

LOL

I like the grizzly thing on those, but I dont like that it classifys the material out of the water. For clay or saprolite, that is going to add a lot of work.

Theres got to be a way to do it that submerges the material in water while accepting bank run material like the bazookas do, without interfering with the sluice operation. Perhaps even a sluice upstream of the main sluice that's only job is to accept bank run material and classify it, and then feed the oversize off the sides. I think I could make something like that but it might (ok it most likely would!) be a hassle to setup two sluices and it would certainly need adjustable legs like the setup they show. But the benefits might make it worth it.

Interestingly enough, The clarkson study (that study is 31 years old now!) also backs up something I found from testing my owns sluices. On page 22 and in the section on punch plate it reads:

"...If punch plate is too close to riffles, the slurry velocity becomes to slow to power a vortex, and the riffles will fill and pack. Riffles located below punch plate are much more sensitive to changes in slurry velocity (IE surging) and once filled take a long time to clear."

Can read more from the study here:

Basically Clarkson is saying he found back in 1980, the same problems I am having now. Though with that study, they were looking into gold recovery methods for commercial mining operations, and not trying to design just a sluice box that accepts bank run material. But the problem is the same for both!

I spent two hours this morning making an attachment for my AU Trap. I used a leftover piece of Plexiglas, and a 5 gal bucket. I bent the Plexiglas into a bat shape to assist with runoff and slide onto the Sluice. I cut off the top 4 inches of the 5 gal bucket. Then I cut out a hole in the plexiglas to match the bucket top, and welded them together. The end result looks ok I just need to get the grizzly to test it out.

I still don't think it will out match my DIY Gold Trap, but it would give it a run for its money.

Well have you tried this yet? How does it work out?
