New extraction technique? Rosin tech?

is that a discount code for aqualabs? if so that's a much better discount than they offer during their 420/710 sales.

these days I am using Slick sheet (PTFE) and Oil Slick Pads / DUOs.

Thank you. One more question, if I may.

Do you preheat the slick pads with the plates or do you leave them at room temperature?

Thanks

EDIT: I just tried this. I had 4 or 5 pads but I don't know what brand they are. I heated the plates to about 200F-220F. I put the big one on the bottom and the smaller one on top with a bud in the middle. It totally destroyed the little one on top. Bottom one looks undamaged. I'll pick up a couple quality pads and try again.

They look like 12" wide is that correct?

Do you know how thick they are?


They are 16" wide which works well for me since I cut 4" strips.
They are 7mils. That is .17mm. Triple the thickness of those u ordered

Also.. Oilslick sheet is SKIVED ptfe. Not virgin film.
Needs to be skived to get that glossymore nonstick side.

There IS a skived film on that site...but it's twice the price of the os sheets (if you buying a huge roll )

Ummmm, I'm pretty sure 7 mil is .007 inches, not sure about mm conversion. It's not really measured in millimeter though right? They just say "mil" because it's thousandths of an inch. Atleast I know that from plastic sheeting and the girl in Sacramento confirmed that for me but I obviously don't work in that field so I can't say for sure.

My research, and from the girl I talked to in sac, led me to believe that skived is actually not as strong and not as glossy. Because they are literally shaving the strips off of a solid piece. The Virgin film that is sintered is supposed to be (I'm not saying I know this just what I've been trying to learn) a lot stronger and have a smoother surface because of the sintering process. I'm not sure for ptfe but I know when they sinter several layers of ss mesh to get a 1 micron rating, all they do is lay it out and bake it at a high temp. This supposively makes the ptfe film much stronger.

If you think about it on a micro level, the act of skiving is literally separating molecules and that will leave a rougher surface I would imagine? But laying out virgin film and then baking it at high temps I would imagine make any rough surface smooth out a little?

Well I'll let yall know how it goes, I don't intend on using the .002 for pressing, just for packaging. I want to try the .015 for pressing. I've been trying to use 26 gauge ss sheet for pressing which is .0188. The ss sheet doesn't do what I want so hoping the ptfe will.

At .002 you will need 500 sheets to make an inch if they are pressed together extremely tight. I have an almost new 1000 pack of parchment sheets. When I pinch the stack as hard as I can, it's just under 2 inches. This leads me to believe the parchment I have is also around .002 but the sintered ptfe should in theory be much stronger.

Like I said, I know better prices could be had if I drove down there to sacramento and got a whole roll, which is probably a thousand feet. Just guessing on that but "master rolls" of plastic are usually a thousand feet and half the price of what the reseller sells cuts off the master roll for.

I'm not trying to argue, just trying to learn, hopefully together.

Quick edit: from working with sheet metal I know how thick 24 gauge at .025 is and 26 gauge at .0188. .007 is a little less than half the thickness of the 26 gauge sheet metal. That seems kinda thick to me. Where did you find out the OS sheets were .007? I tried to find that info and couldn't, did you call em?

I just called them, they said it's .22mm which is more than .008 mil. Well shit maybe they do have the best deal. I'll let you guys know how the .002 works out. Maybe I'll be ordering a case of the big rolls and use the icmag discount code next time. Well I'm glad we got that straightened away lmao, thanks GanjaPharma.

I'll order a small.roll right now just to have it to compare and contrast

GanjaPharma - so if yuba had to call them to get the big rolls, I guess you can't use the discount code and get free shipping?

No coupon if you buy a big roll

This is what they wrote:
50 foot roll $145
100 feet $250
300 feet $650

The 300 foot roll is really the sweet spot. After that there is a break at 1000 feet. ($1600)

Cool man thanks for the tip!

I'll have a roll of the OS, a roll of the .002, and a sheet of the .015 here soon. I'll let yall know what I think. Sadly for rosin for good for other reasons, the greenhouse is coming down soon so I'm going to busy for a few weeks. Then I'll have plenty more research material of the highest order and I will hopefully figure out more of the rosin mysteries as far as different pressures and heats are concerned.

I'm still under the impression that the headier the sift, the less pressure is needed but we will see. I'm not trying to use super yummy full melt. I'm trying to put rosin on a production level that can compare with bho.

Oh yeah, RINGO, I forgot about this...

It's a vibratory shaker for cheap down at the freight. It made me think of your kief box. This might help you get more melty yum then the paint shaker. A glove full of di couldn't hurt either. These is used for cleaning jewelery i think.

Sorry I meant to show you this like 2 weeks ago.

Have you used or seen the APE pollen extractor or know anyone who has used it? Considering buying it, but I may just go the DIY route link Ringo did, if it works just as well.

any one of you ever take a some dry sift, heat it to the max n press the hell out of it till the oils come running out

I have an APE. It works great. Just make sure you get atleast the 180u screen. The 220 is too big. You may want a 130 for a second round of longer tumbling. I'm still trying to figure out the best way to go about it.

I'm going to get another washing machine and compare yields and rosin quality with water versus dry.

Yes lots of us have been using sift. I don't think you want to heat the shit out of it though.

Hey gang... as for dry sifting, I use the 150u stainless in my shaker but then I hand screen everything down with silkscreens I bought from Atlas Screen Company.

A nice 20" x 24" with an aluminum frame and pre-stretched cloth is only about $25. Watch if you order because I think they go with mesh instead of microns. Conversion tables are everywhere on the internet if you need one. Here is one... https://www.icmag.com/ic/showthread.php?t=215148

Well I haven't made any rosin lately, i am waiting to get a way to do some cooler than the hair press but it got so friggen hot all i am doing is smoking what i already have and staying cool.

I was going to take pics off all the recent presses and the differences in temp. I have 5 distinctly different products. Chopping down the gh today though! Can't wait to have more research material. I think after this I'll have the fine details of the design figured out hopefully! Yay!

The logic should still hold true. Some strains seem to burn at lower temperatures. Depending on the terpenophenolic profile primarily i think, it seems to affect optimal pressing temperature.
