Rosin Technique....Easy DIY Solventless

About that heated rolling pin idea, something like that was my first thought when "imagining" a good rosin press, using a metal flattener like this....

I am a silversmith, and have one of these rolling mills in my studio. While they do generate great amount of pressure, I think they'll be difficulty in adapting this to our purpose. I use this tool several times a day sometimes, and I think about it every single time.

Has anyone tried this yet? Go kart hydraulic brake....Seems small and could be modded for our purposes, just throwing it out there, I have little knowledge about brake calipers, but if these smash, with one squeeze, then just maybe....... They can be foot operated too......


Also looking at 10 ton hand hydraulic crimping tool, any thoughts?..

I live in the country where they hand out the other Nobel Price I heard you guys have some pretty good weed, wish it was easier to gring some of it back over

Im working on a complete diy press for my buddy to help save him money, from a few youtube videos I found I am just getting him his shopping list for him. The steel unfortunately we have another friend at a steel recycling company so I don't have links for that. I looked up threaded steel just incase there isn't any thats not buried

we will strip the straightner down to use its heat cables between the sets of two plates that were going to weld bolts onto to bolt onto the steel frame
what do ya guys think? Around $110 is what im guessing for a high psi, low heat (should heat fast) hydraulic press.

@iDRINKBLEACH that honestly looks pretty rad. I'm interested to see the results!

Yeah im pretty pumped to see the results. Im wondering if the cord wont be strong enough to take the psi and the two extra plates could just get a cut in it to lay the cables. So they don't get ruined if psi would?
Any one know how much they can take?

@iDRINKBLEACH look into different cables psi max loads.. That's the only thing I could really think of. Or just call the company & ask them if they know.

They aren't just cables, there will most likely be PTC heating elements at the ends of the cables. That guy says in the video that he had the metal plates milled out so it would fit, you need to mill your plates, the wires inside a set of cheap straighteners will not take 1ton psi and the moment they don't is the moment you're risking your life when it makes your whole press live.

I was thinking the same thing thats why i was talking about cutting a spot for them lay. I will ground it also. if it were smaller plates we would use solders.

I know some guys doing this commercially. They press live rosin from ice water extract full melt bubble hash.

How do we suggest doing larger amounts? Is full melt hash my best bet? Im looking at 10+ lbs of product and have traditionally used butane for large runs but would be open to a new technique with similar yields and quality.

I process bigger amounts using my bubble machine first just because the yield is higher on my bubble rosin so I have to do less presses. I was thinking about trying one of those flour or powder sugar spreaders to help me spread my bubble to dry it a bit faster, speeding up my bubble rosin process. I hate microplaning

What's that, if you don't mind me asking?

For bubble hash, using a cheese grater pretty much on the bubble. any one puck theres before using it on rosin or do ya just throw the hash in bags? IMO hash is a lot more giving with less effort/ not as good setup also.

I actually just tried drying without microplaning for the first time. Have gotten a delicious temple ball of full spectrum 3.5-4 star bubble. When I get to 3g I'm gonna squish it into rosin

The ball smells fantastic

I've been getting into some Frenchy Cannoli tek (my bro @Hashtag46&2 will be proud!).

Can't wait to make and squish more bubble! This hash was a pleasure to hand press, such an enjoyable and tactile experience!

I will be sure to report back when this finally gets squished!

^Beautiful stuff, very nearly smell-o-vision lol..



So I was watching a local oil maker on YouTube ( FarmerJoeParker ) and was pretty amazed by what I saw. This dude is taking down elite oil trophies just by pressing store bought 6* bubble in a $30 Remington by hand lol. He's even pressing bubble at 300f for 10s standing on the iron?? I just don't get it lol, goes against everything I've learned...



A great tip from him though is to buy your hair iron from a store (he uses Wal-Mart) that offers an extended warranty and save the receipt, so for approx. $3 you can return it for a brand new one every time you crush it lol.

Also you can get a look into a WA state Recreational BHO producer by looking into his channel, and form your own opinions on how that all gets done

Higher temps are needed with less pressures.

Even less pressure is needed for bubble than flower (so I hear).

Hot damn Brother herb!!!!!
You're damn right, I am extremely proud, honored, flattered....all the good stuff!!!

That Temple Ball is GORGEOUS!!

Isn't the hand-pressing sooooo ..... Uh, rewarding?!?

It's a transcendental experience eh?
I love the process almost too much, I'll spend 45 minutes to an hour pressing about a eighth of an oz, the more it is worked, the more the aromatics will "morph" into a richer, robust spicy tastes of bliss.
Bonding with your resin (Pun completely intended)

Round of applause Brother!
Edit: To keep it pliable and to avoid oxidation...
Keep her in your refrigerator's crisper (double jar, and bag, vacuum sealed preferred, but you can simply suck the air out of a Ziplock bag by zipping it almost closed, then use a a long straw to suck the air/oxygen out of there)

Edit 2: knowing you, you probably already bought a wine cooler?
These are the Hashmaker's best friend...
Zero to very low humidity and keeps a stable temperature of 55F (Ideal conditions for long term cure/storage.)

Thanks so much for the pointer bro! I actually am really needing to do something about humidity, as RH here is above 60% for most of the year where I'm at! Room temps are frequently far far above the 55f you recommend for storage.

Ok, so I am thinking of getting myself a nice wine fridge and a high end dehumidifier to run 24/7. The plan is to keep the entire house around 40% RH, lower the possibility of any mold, then have my hash fridge (wine fridge) set at around 45-46f with lowest possible humidity (should knock double digits of percentage off of the RH of the room).

I've actually made myself a custom hash drying rig, with a glass drying surface which is heated to 105f (has it's own lab thermometer measuring temp from the bottom of the pane of glass too!) to get the moisture out a little quicker.

Gonna get a vacuum chamber and look at vac drying my hashes in the not too distant future!

Air conditioning will be enlisted to ensure that when I'm making bubble, the house is around 65f (almost all of the year it is impossible to get lower ambient temps than this even with air conditioning round these parts).

I am quite sure that humidity/stickiness has been causing me to unwittingly take along particulates with my gland heads - that coupled with my bags needing a good solvent clean on the screens (it is just not fucking possible to keep the screens completely clean unless you clean them with something that can dissolve those headies. Water won't do the job in my climate regardless of how hot or cold - especially the finer screens get clogged).

I'm looking forward to much better hash runs in future!

BTW @Hashtag46&2 I noticed that Frenchy doesn't use the work bag inside his bubble machine and just puts his material in loose. Do you do this? I am fascinated by his explanation of how the work bag inside the bubble machine simply stops the motion of the water from pulling the heads off of the material so easily! I'm gonna try this on my next trim run (which you'd better believe will become rosin!)

Anyone got any idea why when I press with a hair straightener and clamp Im getting a clearish sappy kind of extract that I cant even easily scrape up. Freezing doesnt help as it doesnt seem to ever solidify. Im a little lost on what I might be doing wrong.

Hmmm have you got any external temp measurement brother? Also what is your starting material like.

There are multiple ways I have found that rosin can turn out difficult to collect:

- too much moisture in the bud results in a very wet rosin squish, this will frequently damage the parchment or make oil hard to collect. It'll usually lead to very quick autobuddering (I call it instabudder lol).

- some terpenes have more of a solvent quality in higher quantities. This may be a factor depending on the material you are using (factors like the variety, phenotype, maturity of resin at harvest, subsequent handling/storage etc). In this case, I find not freezing, but placing the parchment on an ice cold surface (leave a flat preferably metal object in the freezer, then when you get stubborn rosin, take this frozen surface out of the freezer, wrap it in a single layer of foil to keep moisture off the parchment and then try to collect).

- too long and too hot of a press (or too much of either factor) can cause decarb. Some straighteners have very high minimum temps for our purposes which can exacerbate this effect. If this is the problem - try to turn off the straightener when it reaches right temp (using independent measurement of temp) and squish before the plates cool down if you aren't already. I suggest using a cheap k-type thermocouple digital thermometer from the electronics store, not an IR thermometer (less accurate).

- the resin on the bud could just have been very oxidized before it got to you. Use the freezer approach above in this case. Despite the degradation (depending on the way it took place), it could still be very nice resin!

Hope this helps man, more info about your material and technique might help us narrow it down more though

EDIT: By the way all, I squished my temple ball today. Got back at least 50% of the 1.3g I put in. Had a blowout first squish so lost maybe 5-10% of yield on the muslin. Too hard of a squish the first time lol, everyone with a vise/hydraulic setup who has tried squishing hash knows what I'm talking about!

Moisture and to high of heat. High heat will burn a lot of good stuff with straightner heating unless its low temp, but water sticks around(sap). I bet you really wanna dab it but your just titanium painting. The only thing I've been able to when was a leave by a fan then it gets tacky. If it doesnt freeze n collect quick, shortly after look for new plates/setup for rosin. Terps/flavor starts to burn at 250ish. Then starts to cook n sap it. I call my first press called the reclaim creator 300-330 :/
Edit* spread that collected oil spot out also before drying. Shouldn't be hard I usually did that trying to dab it haha

Ive tried at the lowest temperature my iron has and for most strains that works great. This particular strain is very fresh, maybe I should leave some out of the jar for a day or so and let it dry out.

But yea, painting it is a good way to put it.. it just kind of slides around.

I think you could have solved the problem if your nugs are indeed still a bit wet/fresh off the plant as you say. A little dry should solve your problem in this case (worst case you may need to introduce a boveda pack if you overdry)

I actually wanted to discuss the state of the resin and drying/curing as it relates to rosin tek a little here.

I have noted that aside from nugs that are still too wet not squishing out so well (instabudder, pool of water over your rosin after squishing, harsh sizzling dabs etc), the state of the cure makes a big difference to quality too.

I have some 4 month cured nugs (boveda pack 62%, mason jar, cool dark place) and then some that have only been cured for almost a month (same source). The squishes from the more cured material smell and taste less planty, make a more boldly yellow colored dab than I get from the less cured stuff.

The taste is considerably nicer from the more cured nugs.

As well, more cure will lead to some natural decarb of the resin on the nugs. I have been thinking a lot about the transfer efficiency of dabbing (recently I shared a study on FC showing that 16mg of THC is retained from a 40mg dab at ~70% THC or so - this likely means that we are not getting full decarb and hence absorption of the THCA when we dab). One way to maximize the THC that gets into your system from each dab is to cure your resin to get more decarb with less loss of terps than you would by traditional crude heat decarb methods. If we get it right, this = less dabs to the dome for more effect!

I'm gonna be trying to really control the variables of my curing from here on in to maximize the transfer efficiency dividends and minimize terp loss.

Also one other observation:

3.5-4 star bubble hash (thoroughly dried, not cured) squishes into much nicer rosin than flowers do from the same material. I squished my temple ball shared not long ago here and got a solid 60-70% return of yellow/brown rosin that smells and tastes like full melt bubble. An issue I have had in the past is that when I squished 3.5-4 star bubble, the rosin would come out so shattery that it was impossible to collect without making a mess, applying more heat than I'm comfortable applying etc.

The temple ball/hand rubbing process seems to have decarbed the material and sap the consistency up just enough to avoid this problem. Still, as I say the flavor is very much closer to full melt than flower rosin flavor so that hand rubbing etc doesn't seem to have hurt the terps much

So my buddy after hearing I was moving ditched out on the project while I was up at wal mart. Mad at him ruining this little adventure we were going to have I continued with it. Tomorrow I will pick up longer threaded steel so I can fit the wood between everything. I will be using the @Joel W. But I am still ordering everything to make bigger plates then I will upgrade the bottle jack. All together the press w/o plates cost me $30. I did pre puck some and man the power difference with less effort is a ton better

Edit*** need to 're drill holes for top plate also we messed up just by a bit. Good thing these plates are circular so I can keep plates matched and 're drill in a different spot.
Another edit* I need springs any idea what kind I should use to pull the ram back down?
