got grizzly?

[Doitlaynstyle]

Just got mine installed last night. Working over options for additional screening or some smaller bars between the big ones if needed. I am hoping to have this build finished by spring lol

looks like it should work!!!
If I werte to make 1 suggestion on the hopper (I know you didn't ask... ) it would be to put some type of diverter under the grizzly to direct the material back toward the head of the sluice instead of dumping straight down. Might stratify a little better.
Looks like it's going to be a sweet unit! What are your box dimensions & what do you plan on running for a pump?

Like this? The box is 10 wide by about 40 long, the header is 10 wide by about 16 long. I have v mat in front and miners moss under the riffles. The second video, right at the end, shows how tight the riffle assembly holds the moss down to assist in retaining the flour gold.

Did a lil more playin round' last night.

good idea with the other rods/classification!

What sort of spray bar assembly are you going to add to the hopper?

Be aware that when grit gets into the crutch tubes it makes adjusting the legs difficult

GG~

I haven't fully decided yet. I am thinking of bringing the supply in either from the right or the left of the downstream side of the header box with a garden hose takeoff on the opposite side. Then encompassing the rim of the header box with a drop in on the upstream side with a big flat spray pattern across the flat of the grizzly. The encompassing ring will have 1/8th holes directed into the box also. The idea of the flat bar of water is to help hold the rocks in long enough to get cleaned.


Make sense? Also I am glad you said something. They are cheap to replace but I will carry extra WD-40 w me lol

As I recall the old Gold King highbankers had only that spraybar above the oversize outlet like you are talking & it looked like it worked pretty well (never ran one). I'm building new spraybars for my Keene & intend to have spray on the upstream side of the header box along with both sides, but not on the downstream side (afraid it will blow stuff straight out the oversize/waste outlet. the Keene design looses enough water out there on it's own!).
Nice design!

Thanks! I think I will probably start with a mister size hole on the downstream side just based on your recommendation. I think with a wide flat spray on the upstream side any over-spray should be redirected. And after my test run I know I am going to have to run all of the ground around the box before I shut down because of the splash! LOL. I am even debating using sprinkler type nozzles to achieve the large flat spray. The hard part is going to be cutting a thin enough slice in the plastic to get a good flat spray.

Im not above hanging a rubber finger style flap over the exit hole either.

For $20 you cant beat one of these for doing a super thin plunge cut into PVC

Yup I will be picking one of those up. Been wanting one for my solar panel builds anyway. So I am thinking maybe this style of Spray bar for mine. The amount of water that I need will require two of them tho. Oh the gears are turning now see 15:40 in the video

I've more thing came in the mail today! Woot!

 

[Doitlaynstyle]

So I did the spray bar today. It's done now all glued. Here is the video of right before I glued it up.

 

[Doitlaynstyle]

So here it is finished and glued up ready for testing. One last thing to do. Build a punch plate and its done.
