Well the PID might power the heaters, but you need to actually bore a hole in the plates and install something hot ;) If the plates are pre-made and have heater installed you can wire right up to then you are all set, if they are just slabs then you need some soldering irons or something IMO...

i planned to purchase this setup https://www.instagram.com/p/BITm3vZg8-A/?taken-by=clean_extractions

says all needed is to tighten its 3 screws into your Harbor Freight A Fame http://www.harborfreight.com/20-ton-a-frame-industrial-heavy-duty-floor-shop-press-37999.html

Plug the PiD controller into the wall to power on and your ready to start pressing

i just need help on the Harbor Freight A frames. Im wondering about maintenance with them etc

Yes, F. I use Imperial and Metric for some reason.

Clean Extractions is, or near enough, a remake of TimeWizard GreyFox's design.

GreyFox has a superior design and I believe the heater connection will take some enail types.

I would definitely compare the two. I was going with CE until someone pointed out TWGF. Check him out on IG.

i cant find their setup. do you have a link to it?

That just happened...
So I finally got a scale that can weight down to the thousandth. I just did a press and if I divide weight of dab by initial puck I am getting 14.5%. I am using a heavy-duty vise setup. How much improvement might I expect going to a H frame hydraulic press?

The control box is vented (SSR's produce heat), the heaters aren't hard wired (adaptable), the spring load design, etc.

They both use the same parts but in my opinion TWGF does the better job. CE seems a decent guy, but I would rather buy from the creator than the copy, and decent guys are all over.

I did like the reinforcing "fins" on CE's press, but that is a minor change one can shop out.

I have a diy 8 tonner. I get 20% usually. The lowest i've gotten now was 15%. I'm not using the best bud on earth either.

Pressure is key.

Noob here. Only squishing clean keif at this point, not sure of screen size it's tumbled through but I'll ask. A buddy supplies the organic material, I'm the fabricator. Here is a list and some pics of my rosin press setup.

$45 HF 6 ton bench top shop press
Sho-Bagz 25u 2"x3" rosin bags
$15 thrift store Toaster oven
Collection of steel pressing plates

I use two different sets of plates, put them all in the oven at once . I can get 2-3 presses from one set of plates, then switch them out with the other set for 2-3 more. The toaster oven "claims" to heat to 400° but after a couple hours the plates get to the 140°-160° range (checked with inferred gun) which depending who you talk to, lol, is pretty good.

I've done the flat parchment and burrito wrap and the burrito is hands down better for me. Pressing and collection wise. Yield seems to be very similar either way, about 24%, which seems a bit low to us. We have tried packing the bags with fine sift, packed down into the bag and also just filled the bag with clumpy material that left lots of free space, which my friend had heard was the hot ticket. Personally I don't like the clumped keif. My yield is better packing fine sift into the bag with only a small bit of expansion room. I've been sealing the open end of the bag with a few small dabs of rosin to hold it closed while in the parchment.

I've found the yield from 3-4g's raw material in a 2"x3" bag is better than 5-6g's in the same size bag. Blowout at the open end is also harder to control, obviously.

The end product is amazing regardless, lol, we'd just like to get a little more, Hahahaha.

So, what are your opinions on:

Packing your rosin bags?
Size of pressing plates in relation to bag size?
Optimum fill quantity for bag size?
Sealing the open end of the bag?
Sift Vs. clumps?
Should my yield be a bit higher?

Anything else we are missing? Never too proud to learn something new. Thanks.

Yeah, well, that's just, like, your opinion, man.
I'd say sift returns are dependent on the starting material and how hard you sifted. I personally like to base my yield off the starting material rather than the sift from it.

Depending on how far I took it, I've had sift yield from 20-60% - it can really vary.

Should have some more solid numbers soon, but currently getting ~8%-15% on various trim tests.

Lol, good to know. Yeah the oven works great. I looked at a lot of set ups and just thought all the electronically heated plates seemed like a lot of over thought. The plates just need to be warm, they don't care how you get 'em there.

I completely agree. But plates that have coils or some sort of heater are a huge convenience. It makes things go much quicker.

And lately i've been upping the temp as i press to get extra oils out. I was waiting until it was at the right temp, and then just pressing right then. Since i started raising temps while pressing the second press has noticeably been reduced to from next to nothing, to really nothing. My second press use to maybe give a dab worth, now it's a quarter of that. It's not worth pressing a second time now, they're just chips to cook with.

I start to press at 200 while the temp is still rising, then press for the 30 seconds. By the time it's done, and i've pulled the parchment, and i recheck temps, it's between 220 and 230. The difference from before is only in the second press, or in the lack of one. I've only tested this with one strain as of yet, the overall yield is the same, taste seems the same as a press at 230, and you probably need to have a press that heats quickly too... but theres basically no second press. everything's coming out in the first.

But please test this out. it's like gradual pressure. I do use gradual pressure with nugg, many say they don't, but i think it makes a huge difference. I'm seeing one with gradual temp rise too. Try it all out. it's turning my second press to nothing.

As far as convenience, toaster oven is to left of press, just open the door, grab the plates with an oven mitt and put them on the press. They are 2" thick so they hold enough heat for 3, first presses. Swap out to my second set of plates for 3 more. That produces enough sticky parchment to keep me busy for a while, hahahahaha. This isn't a production setup, just a cheap, effective way for me to get quality product for the wife, myself and a couple close friends. I do get your point though. We do have a production press planned for a few months from now, that will have plates that are semi permanently attached and electronically heated.

I think the ultimate press would be a type of heated English Wheel like is used for sheet metal work. Slowly roll from one end of ur bag to the other!

Hi all. Noticed the sub is sort of dead at the moment, so wanted to try and jack it real quick.

I've had a 1st run NugRunner for a few months now. It works alright but my yields will range from 10-18% depending on the quality of what goes in. It's very hard to find something that yields towards 18% for me unless I go to the dispensary, and that's 350/oz stuff so it's prohibitive.

I have an ounce of some pretty good looking and smelling stuff now. I've submitted it to the lab for testing though to know for sure. I pressed 2.22g this morning and got .305g back of first press oil or 13.7%. Sucky. I bin 2nd stuff separately and its not usually worth while weight so I don't add it towards my yield weight.

A bit about the first-run NugRunner: It's a manual operated press similar to an arbor press in use. The mechanical leverage multiplies the input force by 3.75. There is a stirrup attachment you can use to "stand" on the lever. If I'm using all my body weight and some additional upper body force, I estimate I'm giving it 300lbs or so and maybe getting 1125lbs applied to the plates, which then needs to be divided across the area to determine the PSI. The diameter of the plates are 1.5 inches. I believe this equates to a 1.77 in2 area. If so, my estimated 1125lbs / 1.77 in2 = 635 psi. Obviously, that's not constant, but it's a baseline to let you all know where the thing stands pressure wise. I hear the number to strive for is 600+ so perhaps force is not actually the issue for me. I'm not sure though honestly.

As for temps, I am using 260F currently but have done some 250F presses. 240F hadn't seemed to work out for me in the passed, but I'm all about trying any suggestions. Length of time pressing isn't too consistent. I try to listen and look at the oil during the press and make a judgement call. It could be 10-30 seconds but usually not 30.

I did a 260F press this morning and submitted 3 chips for testing. 2 chips are pressed twice, 1 is pressed three times. The times were probably in the 10 second time frame for the first two.

I haven't really posted pictures for a reddit post before, but I'll include pics of the press and the reports once I get those in as well as the flower I'm using.

Any help is appreciated. Many people are saying their NugRunner's are yielding way better than I generally am, so I assume it's my technique that's the problem.

what you describe sounds more or less normal to me, when I hear about 20%+ yields I am usually skeptical, its probably waxes and crap beefing up the numbers

If good weed has 15% THC how can you get 20% THC yield from it?

I've definitely approached 20% with top top top flower. However, its just too costly to justify because its marked up so high right now in the medical market in my state.

The answer to this is sort of in your first sentence. When weed has 15% thc for example, and lets say you have a gram, that's 150mg THC / g flower. Whatever comes out of your gram for oil cannot have more than 150mg THC in it, and likely will be less for many real world reasons. However, you could get 10%-20% oil out of the gram depending on a number of factors. But, that 10%-20% of overall oil is not just THC. It's the other cannabinoids, terpenes, and waxes. Depending on how much wax is coming out along with the THC, that will affect your overall % out without a direct relationship to the % of THC itself.

To put that more directly, the 15% weed could theoretically yield 20% overall oil out of a gram of flower, which itself is 75% thc. That'd be 200mg of oil / g of flower @ 75% thc = 150mg THC. Not coincidentally, 15% THC of the gram of flower is 150mg.

That's in a perfect world with made up numbers, but hopefully you follow the point I'm trying to make. The higher overall yield vs thc % can be real and perhaps should be real, because you never extract oil that is 100% THC. There's something else coming with it that is adding to weight and yield.

watching porn makes a guy think everyone has a 9+, reading rosin posts makes a guy think everyone is getting 22+% return :razz:

I've never weighed my rosin yield .
For me , whatever % return it is that I'm getting .
I will still continue to press flowers .

I press .3 g size buds , which is what I use to
roll into a joint . Now I can vape it in a couple of sessions .
But neither of those methods , ever got me this medicated/high .
Which is why , there's no turning back for me .

Of course I will look for a better set-up than my
cheap diy hair straightener .
