O'kief vs APE Tumblers

Hi, new here but wanted to throw 2 cents out there since I couldn't find much info on the main stream tumbler machines. As of today I have had a bitter time with the O'kief people so I figure for the 50 bucks I have to pay to ship it back I can write a review.

The two machines I have had access to are the O'kief 625g unit and the agriculturalpollenextractor or APE 160g unit.

This review is biased on the fact that the O'kief never actually got put to work. I Have turned it on and watched in run for 10-15 minutes. I have been running a APE unit for the past year, 20+ hours a day. And it works. It has some flaws that I will explain later. But as of the last couple months figured it was time to upgrade and go bigger to maybe get things done a bit faster. So after a bit on Google I settled on the O'kief 625g unit. Figured it was going to be substantially bigger based on its capacity rating. Well it turns out there is no universal measure for capacity. The O'kief rating based on grinding up all your stuff before you start if you plan on getting 625g of anything in there. It is almost the exact same size as the APE unit at 160g capacity.

So pros and cons of the two machines

APE Pros
- Very Very fast. The thing spins very quick, I know for connoisseur this is a bad thing but for people trying to move through some material its crucial.
- The loading and unloading is quick. Not really important but u don't have to unscrew anything or take apart nothing.
- Its can be used 24 hours a day with no rest.
- Cheap
- Very quite

APE Cons
- It is kind of messy. Its not really a sealed unit so after a few weeks you will start to have a kief build up all over the room its in. (this was the main reason I wanted a new machine).
- Its on a odd axes, as in the drum falls off the little holder so you have to place a 2x4 under one side so it stays at a angle.
- It slips, this could be a good or bad thing depending who you are. Once the material is pretty much done it will start to slow it down and eventually stop it from spinning. We used heavy duty rubber bands around the opening to keep it going.
- The new screens are a bitch to get mounted on a new drum, tore one trying to get it on, very snug.

Customer service with APE has been good/ok. The 2 orders I've placed one was lost but immediately replaced. All by email and I hate this.

O'kief Pros. Not from personal use, just observations.
- Quality, IMO with the steel screen and how slow it spins you can come up with some of the best kief your material could produce.
- The style is very clean and tidy so you should be able to collect 100% of your product.
- It has a built in paddle inside the drum which is a clever idea so you don't need to toss bouncy balls or kids toys inside to move the material around.
- The construction is done very well, don't think you could drop it but it all fit together very tightly.

O'kief Cons
- Slow, Very very slow. 12 rotations a minute slow. For quality this is fine but for moving through material this would be a nightmare.
- Very noisy. For a tiny little motor it is loud. You wouldn't want this thing in a room you hang out in.
- The longevity of the machine. In the manual it states that non stop use of the machine will void the warranty. It recommends one hour at a time with a cool down period.

Customer service so far with O'kief has be terrible as of today writing this. The lady Becca is very hostile. Her last response to me when I asked if they would help with return shipping since I feel the capacity is a bit misleading was this.

"Out of the thousands we have sold you are the only person with this issue. No we do not pay for return shipping. READ YOUR RECEIPT. I'm done with this conversation.

Becca
Customer service representative"

I have been very civil trying to figure out a way to keep the machine, I really like the enclosed aspect but its not going to happen.

So my final verdict would be if your looking to get work done with good quality I would take the APE machine. If you want the best quality but take your time doing it the get the O'kief machine. This is if money is not a issue.

Check out Bubbleman's Tumble Now tumbler, in my opinion, it's the best tumbler on the market by far, it's well designed and made well...and more importantly, will produce the highest quality dry sift.

all wood construction
stainless steel 150 micron mesh cylinder
rotates at the ideal speed of 36 RPM
magnet access door for easy filling
pull out drawer with a 70 micron mesh flat screen (to produce the purest dry sift)

The O'kief is a cheap plastic container with numerous design faults, I couldn't recommend it at all, my one is collecting dust right now... I haven't seen the ape tumbler in "person" but from what others have said and by seeing videos of it online, it definitely spins way too fast to produce anything but low to mid grade sift...it appears to be a decently produced unit, but the speed it rotates at is crazy (as in, seriously, what the phuck were they thinking! it rotates around in a fast blur similar to the speed of a masturbating monkey on meth) The ape tumbler has the cheaper nylon mesh which will not last as long S/S mesh, it's also 220 micron which is too open for making good quality sift.

Buy the Tumble Now from icmag's main advertiser - Aqualabtechologies...by supporting our sponsors with your purchases, you directly support icmag.com and help keep this site online. This company offers excellent service.

and by the way, all tumblers on the market work and will produce good quality dry sift with the right timing and decent enough starting material, but it's like everything else for sale, i's just that some work better than others, some cost more, some cost less, some have more features, some have a better build quality etc

I didn't say any thing about it since I didn't think it was relevant to the machines but quality is not my personal main priority. For quality we just stop it after 2 minutes and grab that then let it run till done. On your post, do you have a link to "rotates at the ideal speed of 36 RPM"? I would really like to see a spread sheet of this to see how the different speeds produce what qualities.

On a side note of the ape machine. Not trying to sell it but the way it spins it would be very simple to setup a drag to slow it down if one wanted.

I never really thought speed would have much to do with actual quality, seems more that time spun and quality of product would. If you run garbage for 5 minutes you will end up with 5 minutes of garbage. If you run high quality at for 5 minutes you will end up with 5 minutes of high quality. Is that not correct more then spin speed?

the rotational speed of the Tumble Now works just right....a tumbler that runs too fast would be the same as picking up a kif box and shaking it aggressively, that's great for quickly making low grade sift, but not for quality

On a side note of the ape machine. Not trying to sell it but the way it spins it would be very simple to setup a drag to slow it down if one wanted.

I wouldn't set up some type of drag, that might damage the motor or other parts (?) another way would be to fit a larger size roller which would reduce the speed

Ideally, a tumbler could have a variable speed control...I don't think there are any tumblers on the market with this feature.

Everytime I look at this Thread, there are missing posts.

You could get a variable AC speed control unit for your tumbler. You would be able to slow it down., but it will not run faster than its design speed

Both the O'kief and the Tumble Now tumblers have a DC motor with a DC>AC converter...I'm not sure but I think that with a different rated converter fitted, this will change the rotational speed to faster or slower RPM, anyway, why would any one want to speed up or slow down a tumbler faster than what already works at an ideal RPM? ....there's no point as it just comes down to duration and monitoring the fall through with magnification...but the Ape really does need to be slowed down, if not then they should re-name the Ape tumbler, the Centrifugal force tumbler. lol

another feature that would be good for tumblers would be a timer...so you could set the machine to run for 2 minutes, 10 minutes, 15 minutes or whatever...(this is pretty easy for most of us growers to set up if we have a spare timer sitting around)

Industrial sized tumblers could be fitted with refrigeration and dehumidifiers to maintain very dry, low temps. ..and also could be built (like the Tumble Now) so that the plant material is rotated in a mesh cylinder then the sift falls down on series of finer mesh screens that are vibrated and have mechanical sweeping "arms" that "card" the sift to purify it.....with decriminalization, all this will happen.

Are you sure, like being censored? If that's the case, it would make the thread more of a commercial, than an open discussion? I am hoping this is not the case, hoping I get honest, non-bias/non-commercially driven information here? Am I?

I have no experience with either of these tumblers, but lots of experience besting tumbler production rates and quality.

I also have a number of years experience designing tumblers for industrial application, chemically milling exotic alloys. I started to make my own, but discovered a better idea!

Consider building your own Grinning Reaper, which uses vibratory shear action, rather than tumbling.

Vibration waves on a single plane, produces significantly more shear than tumbling, while breaking up the material less.

We yield around 10% gold kif in 3 to 5 minutes using dried and frozen material. More than about 10% and it starts to turn green.

Also shown, is the Resin Reaper, from which I got the idea. Both vibratory systems are messy, but we also added skirts to keep the material from shooting out the sides.

PS: The down side is it is annoying to listen to a palm sander drone on....................

I thought about vibration to separate the trichomes from the plant. I was looking at a Syntron-type of device mounted under a metal plate with by dry sieving frame sitting on top.

I like your idea better, plam sander, K.I.S.S.

I also tried it with ultrasonics, but didn't have enough wattage at 60W, and have a project scheduled to try it out with an acoustical subwoofer seat shaker, using music to drive it.

I really like this idea but doesn't suit my application. We always tried to think of ideas like this for shaking down our bubble bags. Closest we ever came was strapping the stand that held the bags to a washing machine that was lopsided.
