Hi ya'll!

I know I posted this somewhere, but can't remember what I called it in the original post, but here is a picture of our do it yourself Grinning Reaper, that I got the idea from after seeing the Resin Reaper.

A salute to the mind conceiving the principle!

It is a relatively simple device and smaller than the Resin Reaper, but which works damn well, producing 10% primo quality kief from frozen bud in 3 to 5 minutes.

Ours was built entirely from scrap, other than the 130 micron stainless screen that cost me $6.50 sq/ft.

The vibration is from a palm sander, that had a broken sandpaper clamping system.

Like the Resin Reaper, our original prototype used Lexan for the vibratory plate but it soon cracked at the mounting holes, so we used an available piece of 3/4" Nylon sheet stock.

The Resin Reaper doesn't use a palm sander for vibration, or screw mounting holes, so I infer they don't suffer from the same issues.

We did have to add skirts to keep the material from bouncing up through he cracks between the vibrating plate and the screen, so as to keep down contamination.

I never got to have a shoot out with a Resin Reaper, but for ya'll with more time and junk lying around than money, here is a do it yourself design that works damn well for home kiefing.

The principle is also easy to copy using ones imagination and other materials.

Ohmmmmmmmmmmmmmmmmmmmmmmmm!!!!!!!!!!!!1

One point that I failed to mention, is that our Grinning Reaper blows the doors off the standard commercial tumbler donated to one of our members by appreciative patients, as far as speed and purity. Less than 5 minutes, vis a vis our standard 20 minute tumble.

Primarily the reason that I designed, but never built a standard drum tumbler, even after accumulating the parts and having designed numerous chemical milling tumblers during my previous lifetime before retirement.

Vibration has more shear energy to break off the trichome heads, than just tumbling and adding balls to speed things up in a tumbler, also adds more plant material.

very cool . i had an okief tumbler and gave it away . never liked it. thanks for the pics. that thing is built like a tank. unfortuantly i dont have a welder at the moment.

that some great work, really like the sturdy way it's put together. how much trim can you work at a time in there? and how hard or easy is it to get the old trim out and put new in?.

you got some great handy man skills man. impressive!

Thanks ya'll!

I run about an ounce at a time and just turn the unit upside down to dump it..

Well, here is the ultra sonic test sled, and I just eliminated another technique that didn't work due to under design. At only 60 watts of power, the ultrasonic system didn't produce enough energy to break the trichomes free. I estimate the shortfall by a factor of about 10X, so will move on to the next experiment using a slightly larger resin reaper and a 12" woofer.

I can drive it at 160 watts, using an 80 watt per channel Sony amplifier, that Bob picked up at an estate sale for $20 and bridged the two amplifiers. He originally built it, along with a driver, for our first 80W ultrasonic transducer, which didn't survive our experiments.

The ultra sonic unit will move on to our experiments making infused fruit for truffles. Hee, hee, hee................. Nothing ventured, nothing gained................

Automated vibration is definitely the way to go GF....do keep us informed of your findings (as you always kindly
do!)

I've tried using one of those dolphin shaped massagers held onto a flat screen and I'm sure an orbital sander or other type of vibration source that that was fixed in place without the need to manually hold it there would of been a lot more pleasant as it was annoyingly noisy and after a few minutes the vibration from the hand held massager works like an Oriental water torture ...but it really got the roughly ground up trim vibrating around, and as you noted, it worked really quickly and the results were ok with larger opening meshes (eg 125 ~ 150 micron), but I found when re-sieving with it over finer meshes (60 ~ 100 micron), it was not that effective as the dry sift tended to "dance" & "roll" on the mesh and also tended to "pool" or group up in corners or sides on the square mesh screens I used unless it was also carded at the same time. I don't think vibration alone is the answer (if the question is finding the best way to automate dry sifting plant essences)

Perhaps with the ideal rate of vibration, a circular mesh screen formed into a dish, the right quantity and the ideal plant material particle size to begin with would eliminate the "pooling" problem?) ..and it would be more effective?

perhaps also with the addition of a lift and drop action would assist in being more effective?

As always, your insight is golden bro! I haven't tried to automate resifting, but just added it to the project list.

I'm visualizing a frame, with one or more mesh bottomed trays in it, which has a motor driven eccentric weight, horizontal to its vertical axis.

If both the motor speed and the eccentric amplitude were adjustable, we could run a wave form in any direction that we pleased, including a lift and drop action.

What I will do first though, is consult with some of my retired engineering buddies, whom designed commercial sieving equipment for the foundry industry. More heads are better, even if some are cabbages.............

Hey there greywolf, so I have a question for you, its off topic for this thread but since its yours I thought I would ask. So I have been successfully running your mk111 for the last few months and BTW I absolutely love this machine and recommend it to anyone I come across asking any questions about CLS systems. Anyways what I want to know is how to get ahold of you guys at wolfwurx to possibly build myself a new system. Its time for upgrades and I'd like to go 5 lbs or larger. So can you please send me a link? For some reason I can't find out how to get ahold of you guys searching online.

Hey GW! I'm an engineering student and I have put a fair amount of thought into redesigning tumblers. I think I have a fairly solid design plan, but would love to work with you and anyone you think could help to create a really top notch tumbler.

Greywolf, have you made any improvements upon this design in subsequent years?

Solly, no! Been too busy on new toys to play with my old. We did use it recently in an experiment extracting from kif, reminding me how handy it is.

Check your visitor mail. The WolfWurx site is undergoing reconstruction.

Good, ah sincerely believe we need more engineers and less politicians! No doubt more tumblers too, now that the demand is rising.

Be happy to look at your plans and add my thoughts. As I recall, you are a River City denizen, so lets schedule something via PM.
