New extraction technique? Rosin tech?

I did the same with a generic quick clamp. Worked like a charm.
I can also confirm that you can mount pads with heat and pressure to the Irwin 600lbs quick grip that HMK uses. I believe I got the idea from ThirdEyeVision as he mentioned his heat pads adhering themselves in a post so kudos should go to him for finding this out XD. The only issue I had with using heat and the Irwin pads is that the rubber pads stretched and warped a little bit. I still need to make up a mount so the flat irons will be aligned properly on the quickgrip.

Cut the excess mesh off the tea bag, don't fold it over if you can't fill the whole bag. You always lose a little to the mesh but as long as you don't fold the excess over you shouldn't lose much. Is the surface area of the filter equal to the surface area of what you are using to press on it with? Or is it smaller?

yeah but it was actually just a 25 micron screen I cut into a square and folded. i had it just a hair smaller than the heating plates. I folded way to much over I think for sure. it was an odd experience once again lol, definitely going to pack the tea bags out fully or try and get something like the hardpresspouch from @GoldAsh on instagram, great results hes been having with flowers!

beautiful! how much force does this baby have, so clean dude!
Thanks man :D shes almost as clean as I want but its hard to get any better with the parts I have :p.
are psi scales easy to come by? I don't have anything to measure it currently but the clamp is rated to 1500psi. Id say turning it with hand force I can get to around 800-1000, I'll add a prybar of sorts into the mix and see if I can tighten it down more.

It's very satisfying turning the handle and squishing so far tho :D
I've only run one test on a small nug this morning but the results seemed good on the oil slick. Tried a repress on parchment and blew it out. May try the oilslick with the parchment to see if I get something nice to work with for kief in a pressing screen.
Is there a specific screen material that everyone is using for pressing? or is it kinda just anything goes?

25 micron screen seems to be popular.

sunfire has been having good luck just using unbleached coffee filters.

i saw the medisun press. smart simple design. ledoneshot bought one so hopefully we'll get an opinion soon.

is that price for the dies only or does he ship you the arbor press too?

i'd have a hard time paying a mark up on stuff i can get for next to nothing at harbor freight...

On his site the total combo is 600ish? Just the heating plates are 300. And the controller is another 300. The press itself is 75. I can understand needing to make money and if people are willing to pay 300 dollars for some aluminium with a heating coil then hot damn.
Hopefully it has good results. Ledoneshot let us know maaaaaaan ;)

http://medisunfarms.bigcartel.com/products there is a better link listing all the parts separately.
Thanks for the reply regarding screens. I have tried coffee filters but they seemed to absorb a lot of the oil and left me with nothing on the parchment or oil slick. Could be the brand of coffee filter I was using. Have people found better luck with metal, fabric or plastic screens? Im trying to find a mesh with a good non stick material to keep oil wastage down to a minimum.
I saw some squish bags by golden ash(i think?) On instagram. Apparently they work very well and I was wondering if anyone knows what type of material is being used to make those bags?

yea @gold_ash and @oakii_dakii are both selling pouches.

also APE has screen bags on aqualabtechnologies or they used to anyway.

i've seen some larger mesh ones. i think oakii_dakii has some 73 micron pouches for flower pressing, but if youre running hash you'll prob have better results with the 23/25 screen.

fwiw i've made a lot of flower and trim rosin and i haven't used a filter yet.

if you pre-press the material into pucks or snakes or rectangles, you won't get much contaminant. i just pick out the errant plant material before i collect the rosin. usually not more than one or two pieces per squish.

i'm sure the filters become necessary at a certain amount of pressure but with my little HMK press i haven't run into any problems from not using a screen yet.

I do pre press my nugs for runs which definitely helps. I was more so looking at filtration for cleaning up a dirty drysift run without losing much oil. Hopefully i shouldnt need the bags for the higher pressure i am using on nugs. Testing needs to be done ;)

Aluminum has 4 times the heat conduction of steel, the cool edge isn't going to be cool at all really. This is a nice plug and play set up though. Still no TC close to the surface though so idk how it was routed. That nug pile looks awfully moist. I think moisture gives you better color, need to experiment more but that rosin was glowing crayon yellow!

All filters will rob some return I'm afraid. For sift it's pretty much essential. Everyone is using the same monofilament polyester or nylon.

Yea i was kind of wondering why they would even say they had a cold outer edge when the whole thing is a solid piece of aluminum. Would like to get a heat sensor on the edge to see how much of a difference there actually is.

As for how the unit is routed. It looks as tho there is a slot cut into the side for the heater to slide into. you can see it on a few of the units that are rotated the correct way.

thanks for replying with mesh materials good sir. I was never too sure. I'll try out the material I have here and see if I can get any better results.

waxi you can get empty tea bags homie lol.

i've been meaning to try them out. i have some somewhere i'll dig them up.

oh one tip i've read is to turn the filter pouches inside out so the seams are inside the bag.

first press with the t-sac is promising!

didn't have a blow out. rosin is clean.

my major concern is loss to the filter bag. i'll have to try with a scale next time and get some numbers.

Good to hear! How much were you able to fit into one bag? Also what are the dimensions of said bag?
I was trying some test press' out last night. Did a 3 gram press for the luls and ended up having half the puck squeeze out the side. Ill need to use the snake method to help keep things under control. May just buy some 3/8 pvc tubing and compact into it then push the whole long snake out and cut that into lengths for pressing.

greyfox... Not sure the 3/8 tubing will work... I tried a capped extruder to make pucks, but they were always to wide when hand pressed...almost need 1/4 especially when the snakes are SOOO compacted....sucks when you have even a tiny blowout the side of your press, the flower material jsut seems to suck up all the rosin..lol

Thanks for the heads up. I was planning on using 3/8O.D. pvc which should be around 1/4 I.D. I believe. I'll have to check to make sure. From the test I did last night the K-Clamp seemed to work really well on the compacted material. Just need to find the right dimensions and weight I can squish optimally. Definitely not 3 grams XD I may have to math out the surface area of a snake vs my plates and go from there to get optimal sizing.
my plates at 2"x3.5" so I'm hoping I can press 2 grams but testing will be the true test:D

Rosin tech is not new by any means it was posted here on icmag in 08 and 07 on fullmeltbubble forums. Its a stupid tech it is complete opposite of what every growers intention is. We dont dial in light spectrums, feed schedules, and training to immediately lose everything we got the plant ro produce by heat pressing it. Thats just silly and shows that most of the people who think this is NEW dont research a damn thing

Good call. Rosin does seem to be a fad....like the internet.
