Rosin Technique....Easy DIY Solventless

Oh that raises a question that I think has been mentioned a while ago, but not in depth.

Can you press fresh material? or does it need to be dried/cured?

The consensus was that it doesn't work well with fresh material… Is that still true?


John Berfelo presses fresh frozen all the time, calls it "frosin" lol


Edit: should note that he and bubbleman have commented on the "sizzle" of fresh material and slight harshness...

Gah, I needs to get a friend to go half and half on this press.

I wanna go lower in temp, and apply more pressure.

I make rosin from high grade Morrocan hash wrapped in cloth, and it is LOVELY now that I have a good hair straightener tech down, but I need too much heat. I want to make clearer rosin, that leaves less residue on my quaryz nail. I believe upping pressure and lowering heat i the key, and my iron isn't really built for that :lol:

And I also have to try this tech where you just heat the c-clamp itself!

Moved on from the straightener to simply using the vice grips.
I took a torch and heated the vice grips directly on its 1 inch plates (they take temp pretty quick) and with a thermometer waited till they dropped a bit to between 200-250 degrees F.

I tried this with my harbor freight locking c-clamp pliers and it worked pretty well. temp control was difficult though since my IR gun can't read bare metals accurately. I tested it by pressing some printer paper and observing the discoloration. Once the discoloration lightened and eventually stopped, I pressed the nug. it was still too hot since the weed coin had a brown, toasted appearance and the rosin was decarbed. Wasn't expecting much though, so I was pleasantly surprised. I suppose that's the beauty of rosin tech -- it can cheaply and easily be done with household materials, and by novice hashmakers to boot. :clap:


@NorVape

I'd try a finer filtering material for your hash. People on ICMag say a coffee filter works for kief/hash or you could pick up some 25um nylon mesh. I think the screen rather than lower heat would make it a lot cleaner.

Thanks, Bouldarado! I tried a finer cloth and that didn't work. This hash is pretty different then the one you guys've got. Just watched over the edge with a teenaged Mat Dillon, and the hash those kids were talking about seemed more like the one we have. Big, solid bricks that go soft in your hands. Lots more plant material than the modern hashes.

I'm pretty new with the screens. Any vendors and/or brands you guys recommend?

Back when I first mentioned teabags (before realizing that many teabags have unsafe materials to heat in them), I soon discovered unbleached cotton cloth (calico) works amazingly. This stuff is ideal for pressing, readily available and is solvent reclaimable. :D

Just got a reply back from d-nail about the small press.

It will weigh about 40-45 lbs.

The dimension will be about 2-3 feet of square width and length. The rep wasn't sure the exact dimensions yet so that's why she guessed 2-3 square feet.

So I would guess maybe 1-1.5 feet wide and 1.5-2 feet in length (since the base looks like a rectangle, but then again it could be a square and just looks rectangular in pics. Hard to tell).

She said the height is about 3 feet when the press lever is all the way up (open).

@Silver420Surfer my CC is still pending $335. No charge yet.

yeah if there's a lot of small plant matter it's gonna be harder to get clean rosin, since those particles will get pushed through the screen. I've used these pressing screens as a filter before and they work decent. Just compress the hash into a little log and wrap it in a couple layers. You might also want to try lower pressure...if you're putting a bunch of weight on the initial press it sounds like it's forcing a lot of the plant matter out.


and for that d-nail press...size, and especially weight seems very excessive. excluding furniture and my subwoofer, I literally do not own anything that weighs that much. I think the weight and dimensions need to be cut in half (same goes for price) for the press to really catch on. A small, cheap and portable handheld press is what the average user needs and wants. I've been working on some designs for one but I need to meet with an engineer to see what's actually feasible to manufacture.

So does anyone know how much the small press is supposed to be able to churn out in a given press?

Probably a better way to ask would be how much bud can you press at once.

Great Scott!

My guess is 2 grams would be appropriate. Not a whole lot higher for sure. The more you press at once, without increasing pressure, the worse your yield will be.

Sounds about right. Looking forward to hearing from others how it works. Is there a release date?

It says it will ship in late August / early September.

I will be doing some tests with temperature, pressure, and amounts with the same kind of bud to try and figure out the limit for maximum yield.

I will probabably try to press some dry sift and ice wax too after I make some :)

@Silver420Surfer my CC got charged today. So I'd say a debit card would get charged immediately.

Fucking finally. A hair press just isn't enough. Takes way too much time for the amount returned. But i love the solvents factor.

How efficient is this device's extraction process?

Imagine all of that bho blasted weed that is thrown away, now it'll be perfectly vape-able rosin chips

If this device works as supposed to. Im guaranteed to purchase. Now its too decide if i should pull the trigger on this discounted beta version

I want a cup of that fresh frozen juice to sip on while I'm pressing some rosin =)

I think this method is going to keep me away from making bho. Plus having bubble hash in various qualities with those bubblebags is excellent!

Haha I imagine that rosin juice would taste like straight chlorophyl:puke:

I JB-Welded some plates to the the vice grip clamps. I'm heating it by squeezing the hair iron strip heaters in between the plates. Works almost as well as the arbor press.

Yeah that's what I was thinking too. Too much moisture probably won't work well just like how it doesn't with butane (I'm sure for different reasons, but same concept, too much moisture is bad when trying to remove resin from the material).

Great idea about the vac! I will definitely be playing around with some fresh popcorn material.

Thanks for the offer! I will definitely be asking for your assistance once I get the unit in :D
I pressed some pretty fresh (drying for just a few days) Critical Kush and it worked GREAT.

I'd really like to see the results on this, I could see this working quite well!

However, the teeth in the plates on a vice grip may rip into your parchment/oil slick pad. I would suggest putting flat smooth SS plates over these teeth if you haven't already :)

Latest result.
Pressed 4.7 grams of blackberry kush, super dense and triched nug.
Got 0.8g yield in a single run using my method of directly heating the 1 inch plates of the c clamp, and pressing at around 215-250 degrees for 5-8 seconds.
Not bad, I can see the yield possibly reaching 20% by running the nugs a second and possibly 3rd time.

The teeth on the plates do seem to sometimes create holes/indents on the parchment, but ive had more trouble with the main stem on the .2 nug poking through the parchment which also hasn't been bad just gotta deal with it before you try pressing.
The biggest issue with ripping the paper has been when pressing down if the 2 plates don't come down on top of each other pretty evenly, they slide and create small folds in the parchment potentially ripping it.
But all of the aforementioned issues are pretty minor in contrast to all the positives in comparison to using a hair iron.

I was actually going to buy a cheap laser thermometer for 20-30$, but was gifted a thermometer my friend uses for his HVAC work that you physically make contact with whatever you want to read and can go up to 500 degrees F.
Those are also pretty cheap and have been working great for us and seem consistent and reliable, deff recommend.

All in all at the scale I am working at, heating the clamps directly seems to be the best idea yet!
One idea we have that might speed things up and make things more consistent would be to place a few of the c clamps in boiling water till they reach max temp which should be 212F.
They shouldn't go any higher than that which should allow us to skip calibrating temps and testing with the thermometer. Plan is to press at 212 for 10 seconds or something and once finished put the clamp back in the boiling water and grab the next pair, and so on.

I finally broke down and ordered a low temp digital hair press. I started at 160f but really did not get anything until I hit 230f and then it started working well.

I forgot to weigh anything in all the excitement. Even with a 10 ton hydraulic press this leverage setup works really well. I have a 4x4 block under the hairpress and a 4' aluminum pipe that is using the bottom of my bench for leverage point.

If anyone is curious, I found this kind of interesting.

http://analytical360.com/?s=rosin

Here are some lab results from rosin and a few tests done on post squeeze waste as well. Makes me glad I keep my chips lol, tests show plenty of actives left there...

edit: check out one called Alaskan Thunder Rosin. I was trippin on how dark it was, til I saw 17% active THC lol. Maybe try lower temps guy ;)?

Waiting for jb weld to cure. Excuse the sloppy jb job. First time using it.

10 in wooden hand screw clamp
Super glue
$3.99 thrift store hair iron
C clamp
Electrical tape
Screwdriver was used to break hair iron apart
Jb weld original

Hair iron and c clamp become one unit

Shout out to @Bouldorado and FC for the inspiration of the invention.

That's pretty cool! So the wood clamp serves as a stand right, not really load-bearing? I like that, my home-brew takes downward force so I feel like I need 3 hands, one for the handle one for the parchment and one to stabilize the rig. Yours looks like the squeezing hand supports the rig while the other just shove the goodies in.


Looks like my local dispensary is using one of these:

They just put up a whole tab on their homepage for rosin http://haveaheartcc.com/rosin, still some debate about what is and isn't legal here in WA now though. Some are saying no commercially extracted cannabis resin can be sold, period. AFAIK no BHO is being sold, but virtually all other forms seem to be available atm... Sry going far off-topic with this line of thought lol

The 10 in wooden hand screw clamp serves as a stand and is load bearing. There are 12 inches at Harbor Freight, but they seemed like over kill.

Trying to use this a portable setup. It should be very easy to use. I like seeing everyone's DIY setups. Its like 6th grade science fair lol.


The hair iron used has a minimum temp of like 260F, so I have a IR temp gun and an electric BBQ thermometer. Heat until desired temp, flip on/off switch or unplug. The new rig has on/off switch and orange LED to indicate power. Heated pneumatic press coming possiblly this week. 8x14 inch heated plates.

How much does that dispensary charge for rosin?
