Motorized Dirt Soil Screening Machine

[SkunkWerX]

Defective is correct, I cannot verify I found any sweet spot.
I was in a hurry, in the evening, just to get it installed.

Rather than drag the screener back to the shop, I removed the old assembly and mounted the new discs while out in the woods, using a hammer, duct tape, screwdriver, and bubblegum.

Just eyeballed what looked like 1/2 way, tightened it down, and started it up (at low RPMs) and viola, it vibrated pretty good. Quite similarly to the old flywheel.
No luck involved, just coincidence.

Larry, I don't see these discs "slipping" out of the set adjutsment.
After hitting them with the wire wheel they were pretty slick, but now that they are painted, the painted surface is providing plenty of friction between the plates.

It will probably take some sort of measureable testing to actually find the sweet spot, if there is one. We may find it just vibrates in proportion to how far it is adjusted toward off balance in conjunction with engine RPMs.

More news to follow.

Certainly seems to be doing the intended job.

I suspect you made it a little too tall tho...unless your FEL can reach higher, you're going to eventually bend the poor thing.

Wow.... truly a wonderful tool..... now can I get one?? Thanks for posting the details... am saving this thread for when I feel creative

Not too tall, that is actaully it's highest rear setting. The FEL can go a bit higher, I was running between video cam and joystick lever to do the dump.

When/if the FEL hits the screener, it depresses and rebounds on the coil springs.

very nice video. It seems to work the way you have intended. You have done very good work. only downsize i see is its a tad too tall ? or was this intentional ?

It's fully adjustable for height, front and rear.

it's not too tall.

I could have adjusted it lower, but then it would not have shown up as well for the video. I adjusted it close to it's highest setting to make it easier to see the debris falling down the screen.

SkunkWerX,
Your dirt screener works pretty darn good. Especially impressive is the speed at which the rejected material travels down the ramp. OK now what in the world are you going to do with the good screened material and the spoil? Could it be modified to pan for Gold? Oh and the spring action provided by the shock absorbers at the top end seem to absorb the energy from bucket contact, that part WerX good too, very nice. What's next?

Actually, in searching the web about screening and sifting, I did see info relating to gold panning, gardening (of course) and archeology. Even here on TBN I think someone mentioned sifting for arrowheads? here on the east coast we might find Civil War mini-balls and such.
I'll just be making clean soil/compost for gardening and landscaping, unless I lose my car keys, if i know the area, I can "sift for the keys".

Next up? funny you ask, I was just pondering.
Workshop clean-up is high on the list. Still have the hydraulic adjustable hieght for Tiller Project to look into.
Keep pushing that one back as I am still not 100% sure of the design.

How about you? Rake is complete and working, what's next?
(Besides chopping monsoon weeds?)

Very nice!! Around here making your own topsoil is like finding gold

When I built mine it was a little higher than I like so I simply put the first couple buckets down as a front wheel ramp and then it's about right.

Again good job and thanks for the video!!
