Sluice drop

[wingmaster]

I'm making a stand to run my sluice at home and seen that you want 1" per foot drop, is this the most drop you would want I'm guessing? and you would want less with the more water flow you have running right? Would there ever be a time with less water flow where you would want more drop than 1" per foot? Thanks for any info

Make the legs adustable, box tubing with round stock, and a nut to tighten down the legs...

Depends on riffle height, water flow, and size of classified material being run.

It's all about creating a low pressure area and an eddy under the leading edge of the riffles so that the heavies drop out and are pushed back under the riffle and the light material continues to wash on down the sluice.

The 1" drop per foot of sluice is only a general rule of thumb. (check the mfg. suggested drop per foot for the model)
Some require more than that and some a little less to operate at maximum effeciency.

The sluice is a keene A51 and I made the sluice stand with a 3" drop that has an adjustment at the back for adjusting the drop to be less than 3", but I guess that I can make an adjustment for the front as well if I need more drop. I'm going to be classifying the material to 1/4" the gold will be really fine for the most part unless I get extremely lucky, I'm in Indiana so the gold is very fine stuff. Thanks for the info

Wingmaster, you are a good candidate for the Gold Cube. It works perfect with 1/4" and smaller material and will trap all that fine and flour Hoosier gold. Great to run at home as a recirculating concentrator. Also has nugget traps installed just in case a larger than 1/4" nugget gets run. It's also capable of running about a 1000 Lbs of material an hour!

I know it's a bit pricey but it's well worth the investment for the perfect way to capture that glacial gold.

From one Hoosier to another, it's something you may want to look into.

I hate paying that much for plastic as it seems these days companies are always trying to find cheaper ways of making stuff calling it new and improved and charging more for it. They look like they would work real good for fine gold but that is alot of money, If I dicide to get a plastic sluice for the fine stuff I was thinking maybe one of the Angus Mackirk sluice as they aren't very much. I was thinking of trying to go to Thermal city(I believe thats the name anyway) next year or some other place I'll have to ask around as money is tight and I want to get the best for my money. I seen some other places but I'm not sure if you need to be a member of the LDMA and if thats the case I won't be able to afford that. Thanks

I feel the same way as you that's why I built my own out of aluminum. Plus instead of a square (cube) shape I decided to make mine more of a rectangle which gave me more surface area to collect gold and allowed me to have a longer slick plate as well as eliminating any need for the optional fourth tier.......http://www.treasurenet.com/forums/g...-gold-daddy-mini-wash-plant-w-shaker-diy.html

What part of Indiana are you from? I know several GPAA clubs that are free to join.
