HMK Rosin Press Tutorial

[Arthritis_sucks]

How dry is it usually when u press it? I know some people said more wetter stuff yields better. I had put a few fresh leaves in with this the night before, so it was pretty moist. Does pre pressing help yields? I used this one I showed a few pages back,

same hair straightener from the tutorial, On the setting 15
pressed about 10 seconds per press, The material was pretty firey lil gg4 nugs, the little nugs that arent worth trimming. Im thinking maybe the 2 grams per press made the yields lower, maybe do one at a time....

I press 2 grams at a time an I get .5 per press. I use the edge of a seat or counter to press the clamp tight as it can go because my hands don't get a good enough clamp down. Possibly from my arthritis but I know it gives me more leverage to press down as far as the clamp goes. This is when I get the most squirt action. My yields are lower when I squish just nugs not wrapped cause some hangs on the edges. Just my opinion on how I squish.

Nice! Looks like Im ready to feed my rabbit.... rrr.... press some rosin!

Those are all scissor hash, but I wanna wait to press them till i got some type of screen.
I rolled um up real tight in a cigar roller, then pressed um with a clamp like the one used to build the HMK.

This is them chopped up for later, 1-2 gram pieces, mostly around 1.2-1.5 Id say. This is 48 grams, so I'll report back tonight or tomorrow when i press um, hopefully with uh lil better yields...

Got an old 25u hash bag laying around or know a friend ya can "borrow" his. It has a lil give an assists in the steam evac of the rosin when pressing imho. Tinker 2 grams at a time till you get that .5 minimum if your working with frosty nugs.

It's all about the Burrito-tech

But there of course is more than one way to skin a cat. Many methods to the end result of hitting 20%+

I need to figure out how to post a lil vid of my squish. Doing a big press tonight or tomorrow for a fest coming up so maybe I'll try an get a vid in.

Any suggestions on how to post a video on here?

In the User Menu above there is a My videos option. Not sure if people can or do use it tho brother

No vid yet, but here's a lil Ancient Og squish I pressed yesterday.

Hello AS, first, thank you or a fine pictorial. I been about, doing this stuff for some years and let me say that this group of members these days have become most forthcoming and for me the leading edge of new concepts... Like rosin.. Thanks to McKush for directing me here.. my first contact with rosin was in his thread McPPK. I've don BHO, ISO and RSO processes, I'm liking the 'no other stuff' process.

OK> no stupid questions:

1 Rosin vs RSO.. samey same xcept the process? eat it or puffit.

2 Does the 600lb clamp need 600lbs of trigger pressure to accomplish 600Lbs of squish? Curler and clamp are in the mail as I type and will jump in feet first when the they arrive. Should I order another clamp?

3 If I had the room for the HarborFreight press I'd do it but from what I've read here and seen on Utube, 3 tons doesn't return allot more than the HMK build.. what am I missing?

heya Snook, thanks for the shout out, happy to help cool people like yourself brother.

With the HMK press it doesn't matter since the clamp press is a fixed part of the equation but when thinking re: clamp pressure, think in terms of PSI so the force of your press divided by the area of your platens. 10,000 lbs pressure on 3x5 platens (15 sq in) = 667PSI So both the platen and the pump combined are what is considered when building a rosin press. This isn't as particularly important with the HMK style though, only that you shouldn't go crazy and put huge platens on them since it actually reduces the PSI.

now that i've said that i'll probably hear and find that i'm wrong but this is how I think about it.

My advice is to start with the HMK and don't try to build a larger press yet. HMK is quick and cheap and it works. hand press up your amounts for a while this way. Then if you want check into the bigger units. i can take my HMK camping with me and a car battery with inverter will keep you squishing and dabbing the whole time.

one 30 minute HMK squishing session can usually generate enough rosin for a couple of days for me, i go at it a bit production style.

Now that this has hit 10+ pages and it seems that the original figures are not at 220F, what # on the dial/how many seconds are y'all pressing with?

I'm guessing the HMK will do period. At my age, in a state like florida, well... we don't get out much. 30 minute every few days will do.. thanks McK..

RSO is a different process using solvents, so quite different from Rosin. Both can be used from edibles but I personally would only smoke/dab rosin.

The best thing about this is you don't need to get technical with pressures. (Field of Dreams Voice) If you build it, it will squish.

Pretty damn on point McKush

Now that this has hit 10+ pages and it seems that the original figures are not at 220F, what # on the dial/how many seconds are y'all pressing with?

When I did a temp read with the laser it read 160-165 in the middle and went down to 150-155 around the edges. This was at 12-13 setting when I squished quick for 6-8 seconds per press squishing a total of 3 times per burrito. I lately have been squishing at the lowest setting for 30 seconds about. Every strain presses different so adjust as you go.

You'll be happy with it for sure.

I'll be updating an adding a lil upgrade I did to the wiring an utilizing the housing.

HMK here, I think i recommended changing to a vice grip c-clamp swivel tip in this thread already, but I'd thought I would re-advocate for it. I believe you can get up to 5% more yield with one over an irwin quick grip 600lb. I use this one, a medium sized one, the 11"

Too late, amazon, 2 day... don't care... thought I might add after the 'build' that using a 3/32" drill bit one can drill thru, using the electrical switch for a template, the two holes in the switch and thread the screws you removed taking the apparatus apart to hold the switch to the, sorry McK...Irwin 600lb clamp. If one goes to a florist and asks for a piece of 'cling' it is a sort of 2 sided putty/tape to hold that bitch in place when measuring up.

Pics or it didn't happen Metal handle scares the shit outta me personally. Curious to see how ya rigged it up. I get up to 33% return of certain strains so 38% would be sick!!!

Update

Update

This is how the build should of been from the start with extending the wires on the top and bottom an closing off with heat shrink an electrical tape. I also ustilized the swivel housing and circuit board housing by taking a dremel to it an giving a cleaner/safer press.

This week I'll go through the first posts to add the how-to.

Here's the final HMK.

Proof is in the rosin......

 

[GET MO]

looks good man. My last one i put ductape with some cardboard in its layers around the metal so when i released it could onlypop back so much, so ill never extend it toofar back n pull the wires.

You can vise mount if you attach the control unit to the other side.

not sure why you are scared of metal handles, seems a very weird phobia. I can assure you, they wont break, like the plastic part in my irwin quick grip did after about 6 months of daily use. My dads hasnt broken yet though.

thinking he is eluding to electrical shock via metal handles..

 

[Snook]

the vise idea seems like it could crush the titanium plates but sure would put down allot of pressure.. and its only a little shock..

 

[EsterEssence]

I was doing the vice with the hair straightener, rosin directing away from the heat, in the very beginning, it is amazing how much pressure you can put on plastic.

 

[blastfrompast]

I liked my vice till it shattered, course the 3ft breakerbar coulda had something to do with it....smaller vice and it broke along the guide rail....

I do like the carjack and impact gun in DIY frame for the oddpress here or there now..
