Rosin Technique....Easy DIY Solventless

[Hashtag46&2]

did you hear extractioneering talk on hash church 72 @herbivore21 ? that high terpene extract sounds sketchy as hell lol. i'll stick with solventless for now.

i'll be getting terpene analysis on my trim rosin in a few weeks when the lab i've been working with starts offering the service. i have a feeling that properly squished flower/trim rosin will have impressive terpene content. i'm not sure it can compete with that liquid solvent extract, but it won't have 100ppm of residual butane either.

i made some very melty gumby hash a couple weeks ago. i was pleased considering i haven't done the process in a couple years and i was working with dry trim. fresh frozen has always come out the cleanest in the past, but i got a good tip from bubbleman about a quick rinse in a 45 bag to remove the fines first that i'll try next time i run dry herb.

second wash fused heads (unpressed)

now all these fancy hash makers on the west coast have me dreaming about a freeze drying machine of my very own. those things are pricey! might have to wait a while for that one...

beautiful!!!!

Man that pic reminded me of some of the first full melt I ever made, I knew you'd love it too!

We don't see a lot of full melt around these parts and it is wonderful to see people enjoying the benefits of hash gen 2.0!

To everyone here enjoying rosin. I am finding quickly that 3.5-4 star bubble hash squished inside a pretty high quality nug produces flavor that approaches full melt. Anyone who cannot get their hands on full melt, IMO so far this is the next best thing!

Hashmaking is an indispensible skill for the rosin enthusiast too. A single .3g nug with .2g of bubble does me a good 10 dabs in one squish. Handy stuff!

The hash I'm using is some 3 year cured 4 star THC bomb bubble. It smells spicey, lemony, skunky and delicious. The nugs are some 1 month cured cluster bomb nugs (62% boveda at 1 month in a mason jar cool dark place periodically burped) that taste orangey, lemony and skunky are quite generously covered in trichs but not completely frosted. Most cloudy with some yellow heads.

Together I get a super clear golden shatter that tastes super hashy, very citrusy with a nutty undertone. Delicious! Effect is right down the middle of the road. Not too racy/anxious - not too sedative. Relaxing, uplifting (mood wise) and gentle. Generally I get too much relaxation from the hash rosin alone, but too much raciness from the flower rosin alone.

Hash can really improve over the years!

Hey all, slightly off topic but I ask here because the only concentrate I have is what I make...what would be the best portable option for rosin? Pen of some sort? PM your ideas as I don't want this thread to get cluttered, unless it will benefit all.

I'd say a pen. The w9tech ones are pretty great, stick with ti gr 2 coils though, don't get the nichrome. I hear great things about the puffco pens too! Get oil specific pens, no need to mix in solvents (ejuice etc).

fuck... i need to catch up on the last 10+ pages here. reading this page makes me feel so behind.

parts list for this tonight. guaranteed :

oh and i almost forgot... @herbivore21 @Joel W. or anyone else... someone i know found about 30g of what must be an ISO run. it tastes like my first ISO attempt. consistency is like a tootsie roll. dark and all that. so my question is... can i wrap some of that shit in a filter and squish it? i mean i know i can, but would all the undesirables just flow out as well? or am i better off just winterizing it and going that route? ive got 2g to play with.

I mean you could try squish it, but to me I would go with winterization and perhaps some sunlight/perhaps UVC derived degradation of the solution to remove any chlorophylls etc. Interested to hear how it goes for you brother! That press is looking great btw!

I wonder actually if sub-micron filtration after dissolving the QWISO in a non-polar like butane or propane which is less likely to dissolve plant material could be a great way to remove some unwanted plant stuff actually? Don't try this yet, I need to speak with some peers to confirm that there aren't extra considerations due to the temperatures of these solvents at ambient pressure.

You could definitely winterize with EC (and I would recommend doing so, especially if it is anything like what most first attempt QWISO is like, way too long wash full of fats and waxes), however you're gonna have a lot of plant material in there if this extract is as I suspect, and I would prefer to use a nonpolar like butane that hasn't got the water content like EC, so it doesn't dissolve small amounts of plant constituents from the original cruder extract.

I still need to check with some buddies about how best to do the filtration safely. I do think that filtration at .02 micron using a solution of one part your crude extract to say 10 parts butane, then redissolving in EC for winterization will be best. This way you should get away with one vac purge and minimize further terp loss.

Let me confirm this and I'll PM you with specific instructions that are safe.

To anyone reading this:

DO NOT TRY ANY OF WHAT I HAVE SAID HERE AT HOME. THESE STEPS ABOVE AS EXPLAINED ARE NOT COMPLETE, AND MAY NOT BE SAFE.

I'd actually recommend a certain c6 solvent for the job if you had access to a lab with a fumehood, cold trap etc and testing equipment to confirm full purge - but I won't because this shit should not be used at home - don't wanna get one of my OG FC extractor buddies sick due to hasty recommendations

Nice press, what capacity is the jack? And do the plates deform any under full load?

For the ISO you can use vacuum filtration (like I'm doing right this moment) or even get trickier with a separatory funnel. This is one of my favorite links to share: https://skunkpharmresearch.com/getting-the-green-and-waxes-out-afterwards/

got bored in class last night and figured i would draw up a little train of thought ive had. although i am not sure about how well it would go since the open center would still probably have heat to it, but i figured not as much as a a straight plate on it. i dont think it would be that hard to make a herb pucking device in the shape of a donut either. lemme know what yall think. all dimensions are in inches, and that red line means im basically cutting part in half and showing guts.

 

[Spocks_Katra]

hi guys ive been reading through most of this thread and have a few questions. Im interested in pressing my grinder kief into rosin.

I dont want to spend alot of money at first, as I wont even be investing in buds to press, just what happens to collect in my grinder, I feel if I mess up, Its not as big of a loss.

My question is what are the best hair straighteners to use, at what temp for kief, and how long a press? ive read 20 sec or so around here mostly but would like confirmation,

Pressing rosin is intriguing because I love concentrates for pain flareups but it is not exactly easy to find around me, so id like to start to make my own

any advice you could give to a rosin noobie would be much appreciated!

 

[roboticnightmares]

i just ordered this pretty puppy! 10 tons, baby!

@SamuraiSam thanks for sharing your expertise on HC! it was nice to see a new face on the panel and the discussion was very timely for some of my projects.

that is a very beautiful sagan rig!

Thanks for sharing . I was planning on trying the black bull press from Home Depot with manually heating plates. I'm hoping you can share thickness of your metal plates. Are you planning on building your own heated plates or are you purchasing heated plates for your new setup.

Seeing how you to have moved away from your previous press, has me thinking about also picking up a hart press. I think I'm going to order some plates from onlinemetals and go this route http://www.highsimple.com/diy-rosin-heat-press/. Just wondering if I should go with with even thicker metal since it's going to be used with 10 ton press. I do realize that I'm probably never going to press anywhere full capacity.

Your plan is to place the herb in an O shape with the center hole? If the open center is for rosin to flow, what stops the herb from moving there also? Nice drawing.

Greetings and salutations from a long time lurker, first time poster.

I've been busy machining some I beam (6x6. 1/2" thick). Going to use them for the horizontals. Got some 4" square tube (1/4" thick) 16" long for the verticals. Got some 3/4 stainless laying around. Milled them down to 2 1/2 x 5. Planning on insulating them with some 3/8 white oak flooring I got laying around.

Gonna push the whole thing with a 25 ton jack . . . That I also happen to have laying around.

2 things I ain't figured out yet . . . How to post pictures and how to heat these things efficiently.

On a personal note . . . It's like a breath of fresh air discovering this forum and in particular, this thread.

Now it's decision time . . . Spend some quality time with my hair straightener or fire up the mill.

Most heated plates I have seen are heated with hair iron heaters, adjustable soldering irons, cartridge heaters with a dimmer switch, cartridge heaters with PID's or multiple enail coil heaters with PID's.

will be limited to vertical presses, also gotta make the pucks within range of the 1.5" plate play room post squish. Shoot really I should upscale dimensions... But I feel you on getting it in line properly to squish out nice and even might be a hassle. Thanks! engineering graphics this semester going smoothly

 

[KatManDude]

Would machining plates to be used with e-nail coils from aluminum or brass be fine? I have killed my hair straightener plates with this. Prior to the plates deforming I was consistently achieving 85-92% by weight of my very dialed in solvent runs using between 190°-240°F 7-25second smashes depending on strain and cure level.

So, I settled on aluminum. This baby kicks butt. I'll get pics of inner workings later. I'm busy using it lol.
A 50mm long 50mm diameter rod of aircraft spec aluminum was loaded on a lathe. And 2/3rd the length was turned to 16.15mm then half of that was turned down and threaded. The 50mm face was cut square and filed smooth. This was repeated to make 2 screw in plates that would be heated by "16mm" e-nail coils that were snug on the middle 16.15mm section. Two shields were fashioned from aluminum pipe that was notched on an end mill to allow the coil lead to exit. These also function as compression limiters for the edges of the plates. They are held in place by the contact of the heat plate when tightened. The ram of the arbor was loaded in the lathe and faced square then drilled and tapped to allow the top plate to screw in. A 4mm stainless steel plate was drilled and loaded in the lathe and turned into a 55mm circle. This goes between the top heat sheild and the ram end to allow the shield to tighten. A section of 10mm aluminum plate was shaped, drilled and tapped for the bottom heat plate and drilled and countersunk to allow it to be mounted to the press via the arbor spindle hole which I tapped. As I owned an e-nail I needed a second so made one from parts on Amazon for pennies.

Close up of 1 plate and a 22.53% by weight smash of Mr. Nice Guy.

Seriously thanks to everyone who contributed something to this thread as it all inspired me to stop using solvents entirely.

 

[KatManDude]

Money shot. 25.43% by weight total. Pictured is first presses collection in one pile then a collection from stacking all chips folded-in-half and repressing 20 seconds. It's .86% of the flower's weight, 3.5% of the total rosin. Doing the math based off my solvent runs, which give me 27.5% for this strain, I am getting 88% by weight of total extractable desirables on the first press and almost 90% should I stack and repress. However..... This is so much better than my solvent extractions and, dare I say, I'm pretty damn good with those. The color and consistency are almost identical to my solvent runs but the rosin tastes a world better and gives me a much more enjoyable effect. (edited due to math error)

 

[MileHighLife]

Finally finished up my rosin press project

The Press-cise

Dake 10 ton press, 2.5" x 6" 304 stainless steel plates and PTFE heat inulators

8 40w 12v 3d printer heaters

Each PID controls 2 heaters. Inside the box are the 4 relays and 2 120v to 12v 30a step down transformers

Thanks to all who paved the road for those of us just getting into the rosin game. Special thanks to @BoogerMan, @Monsoon and @Joel W. for all the inspiration and ideas.

 

[Copacetic]

WOW!
There's some great works of engineering appearing here lately.
@MileHighLife and @Sabalism, those presses are really something else!

That rosin looks/sounds like the perfect dab Sabalism

Can't wait to see some of your product Milehigh

 

[roboticnightmares]

First, thanks to all the magicians putting together these setups and sharing the priceless knowledge.

About half way through the thread their were questions raised about safety of using parchment under such pressures. I am wondering if there has been any consensus on the safest material to use. I want to grab the dake 10 ton press and put together my own plates. The only thing holding me back is the parchment concerns. What say you?
