Hi all,
The last weekend was quit successful, here are the results of the past days:
Here is a picture of my original box:
Too much stuff inside so let's get funny and cut things out:
As mentioned before I taped one half of the holes (1/8) and drilled new one (2mm / 0,08 inch?).
Additionally I drilled 1/8" holes into the end of each tube:
Next day I put everything together and tested again:
I found that the diverter baffle is mandatory so I did a prove of concept:

Now the efficiency is as I imagined at the beginning of that project
Than I got cocky and feed my tool with the semi-classified material (<1/2"?):

A slick plate helped a bit:

Better than the first run, but definitely not what I expected.
The outcome was that I had to attach a classifier.
But how should I do that?
Just putting a classifier on top of the fluid bed makes no sense.
Needed some pump or stream driven feeding mechanism.
The solution was a slick plate with an attached punch plate.
Additionally I reused the cover from the box and cut out a bit.
Here you can see the diverter baffle:
I still hat no glue to assamble the pieces.
The solution was to use some old metal sheet, riveted it to the slick plate and glued (plastic pistol) it on the cover.
The punch plate is also glued on the cover.
Tataaaaa! I created some kind of bazooka without intent, just evolution
With 4 screws i am able to detach the cover and plate so I can use the fluid bed as before.
I used my second 1100 gph pump and attached it to the slick plate and did a test run.
Unfortunately I have no video nor picture as it was dark already but I will create one later.
As far as I could see, it worked pretty well. Just the bigger pebbles, sorted out by the punch plate did not pass the "sluice" like the bazooka because all 1100 gallons got sucked by the fluid bed ^^.
So I had to clean it by hand after some time.
At least, it catches the swimming flaky stuff I am dealing with in our region.
Explicit loss tests will be done another time.
Now it's time to go to the river!
I'm looking forward to any comments or improvements you have.
