This worked too, but was too slow for me

That’s some really nice DIY engineering @99PerCent!
I received my package over the weekend and just barely got enough time to open it up and get it going.
This the box ready to be filled and it filled with frozen Sour Diesel that my old buddy Mud gave me over the weekend.
I placed the cap plate back on the tumbler and place it in the freezer with the power cable hooked up.
The final thing to do is adjust the twist dial so that it spins slowly, just fast enough to hear the material tumbling but not clinging to the sides when it spins.
I’ll experiment with different durations as we go. I’m expecting some green in the sift, because the Sour Diesel was in a sealed jar for almost two years.
Ladies and gentlemen,
The results are in and the used up Sour Diesel 
has been placed in a jar just in case we missed any tasty trichomes.
Damn! I’m awestruck by how well it worked. I’ve got tons of blond dry sift. 1 hour in the freezer spinning at medium low produced almost white dry sift and 2 hours produced twice as much, but more blond. No green or brown at all!!! I’m sad now that I’ve spent so much time trimming stuff I could have just dry sifted with almost no work.
The product design is deceptively simple. The motor in the bottom is little more than a cheap radio shack motor, but hot damn it works perfectly. The micron screen cylinder is very well constructed and appears to be tack welded into place which means it should last for years. I’ve spent a lot of years being disappointed in overpriced cannabis products, but I’m giddy with this sifter. 
It’s perfect for running about a half ounce of inputs. I filled it to about a third full and broke up the frozen buds with a metal skewer rod I kind of swirled around in the jar before dumping it in the sifter.

Yours should work better than the other, more screen surface area.

Pro tip for all of you tumblers. If you want to clean up your farmers grade, you can put it in a jar of cold water the resin glands will sink to the bottom and the contaminant will float to the top where it can easily be removed. Decant the water and dry like you would water hash.

Good thing I’m growing 100% organic with zero sprays! 
I’m going to do the ice water test on some of it just to see though!! 
You’ve got me curious now.

Gonna link to my Dry sift tumbler build (it’s so hard not to type Tumblr lol)
In case anyone searching wants to see a DIY

Works with dry ice hash nicely I’ve heard.

@Jellypowered I wish I’d seen your tumbler when I was searching for DIY sifters. That’s a really impressive and professional quality recycling of an ice cream maker.

I’ve never thinked about to do that with an electric “tumbler” lol Make sense.
The output is top grade damn.

3 gallon bucket.
Bungee chords to hold lid in place.
4 eye screws for bottom, 4 for top. (Used to hold the bungee chord into place! )

These with ranging micron sizes 75, 100, 200, 400 micron.

How does the bucket sit on the base? Unit is 9-3/4" (I am assuming base is less as this is probably the total with - chamber is wider) and I believe the base of a 3 gallon bucket is about 11 or 12 inches.

There is a screw bolt in the middle. It’s secured and will not move. The bungee chords are to hold the lid in place.
@I_thewindcries Merged your topic into this one as it’s relevant.
I Like it. If you find that harbor freight vibratory tumbler is too loud for you,
I have Hornady 050202 M-1 Case Tumbler, 110V and it’s so quiet you forget that it’s on.
Thanks for the ez-strainer link as well. Nice for a 5 gallon bucket

Oh, right, the shaft that comes up in the middle to hold on the lid. Been a while since I used a case tumbler/polisher (don’t reload anymore). How difficult is it to get the keif out after? I would guess a rounded (same curve as the bucket) would work, right?

I’m curious to see the quality of dry sift that comes out of it and any observations about duration versus quality/quantity.
On the PollenExtractor, I’ve found that about 2 hours at a slower speed gave me just trichomes, 3 hours just barely started to include plant matter, and 4 hours produced a noticeable change in hash color. I also found that the best preparation method was to break up the flower in the sifter, after freezing both the flower and the sifter. To the best of my understanding this creates a situation where the flowers break up nicely without going to powder, even with older materials.

Thanks for the info on timing. I was going to put 20-30 glass marbles in the top tray in order to agitate the plant matter. Do you think that’s a good idea? Or should I just run the material normally?

I haven’t gotten around to making the rig for the vibratory tumbler, so i can’t speak on it’s results yet.
I found with my 110 mesh (approx 150 micron) silk screen that I get just a bit of plant matter in the dry sift, for me it’s no biggie. Personally myself I am not brave enough to try the hash as I have a low tolerance lol. Wife likes to put it on her bowls though and says it adds effect and flavor.
I break up my flower/trim by hand (just a good squeeze of the trim to make smaller chunks) and pull the bud apart into small chunks. I have thought about using a coffee grinder to rough process flower into pre-ground chunks, but the key to the whole process seems to be how cold you keep it. I don’t have a large enough freezer to run my apparatus inside the freezer so I imagine my results are a little more limited than yours.

I know that when I was trying to use a bubble bag as a dry sieve, that adding crushed dry ice seemed to help keep everything freezing cold outside of a freezer and it acted as a sharp sided agitation media. I’d highly suggest dry ice crushed into pieces about the size of a quarter (or the equivalent sized coin 
) at a rate of approximately half a cup per ounce of plant matter.
Frozen marbles could be good too, I haven’t tested those so I can’t speak on their effectiveness. I encourage you to experiment with them @I_thewindcries!

I’ve tested “frozen granitic cubes” for manual dry sieves (because water in my hash is a bit a no-no for me) and it don’t work well. You need too much cubes to keep the temps stable, and they weight too much. You get green too fast.
I think than you manner to put the tumbler in the freezer is just a gold idea hard to beat lol I’m planning to watch after “camping” freezer to build directly the tumbler inside. Well, not entirely true : to ask to a friend to build it for me on plans because i totally sux at dabbling this kind of things lmao

I looked up the recipe for using an old ice cream maker to convert into a hash machine on the other OG site. It looked compelling and easier to build than my rock tumbler design. I found a motorized ice cream maker at the local Habitat for Humanity store. It was missing the middle paddle for making ice cream, but that is not needed for hashish making. I will cut large slots in the sides of the canister with a Dremel drill cutting disk, and put silk screen over the slots. I will also add some cut half inch wide 90 degree aluminum railing inside the canister to support the canister and agitate the bud. That is about all that is needed. I will wait a couple more months until it is freezing outside, and just run it outdoors when it is below freezing with frozen busted up buds inside. It looks like it will be able to do an ounce at a time. Total cost is $7.50, $3 for the ice cream maker, and $3.50 for the aluminum rail. And whatever the polyester ‘silk screen’ and some duct tape costs.
