about what angle does a box need to run at and about gal per minute it needs to run correctly, and what size should i screen down to before i run it through the box ? ty Doc420

thanks guys, im in Missouri south eastern and gonna try up in northern missouri, i set my box up last nite in a long cooler and was using about that angle u suggested with a 1/6 hp sump pump and used some material from here with some lead in it, i figure thats the heaviest i got to work with at present time, the problem i had was the bigger stuff under a inch, just wouldnt go over the ridges in the box they are about 1/2 in tall, dont know if i like that, but it is carpet not moss also, it caught most of the fines but i had to put it at about 45 degrees for the rest of material to move. so u think that pump is big enough, had a pretty strong flow i think, any comments would be helpful, my box is 30 x 7.5 with about a 10 in mouth . ty Doc420

Basic guide.
level across the top and bottom.
1" of drop per 1' of sluice length to the bottom.
That is all I've ever done, for 20 years.
You don't have a level with you?
Throw in some test material.
If it gathers to 1 side or the other, that side is too low.
material should gather evenly behind each riffel.
That,s it.
