Rosin Technique....Easy DIY Solventless

I can also confirm that the products you guys are referring to are fraudulent, doctored images from D-nail originals. Allegedly the individuals responsible for the fraudulent listings are Americans - not Chinese!

Also D-nail buy existing t-shirt presses from China and put in their own controllers for both plates.

They do not retain the Chinese electronics, but rather the mechanical press side of things and the plates are retained (I am unsure about whether they use the original wiring for the one plate which was already heated, but I doubt it. I can speak with the man who designed the modifications to confirm this though next time I am in touch with D-nail people).

Further to this, remember that the price that these presses are offered at really is not a hell of a lot more than the original t-shirt press, I recall the original costing a couple hundred or something anyway

I've also yet to see any other good purpose-made home presses (not to say that there won't be loads of them inevitably cropping up eventually!).

There are some potentially better presses that I have seen available, but these are large commercial presses, designed to press major weight and seriously not products that lend themselves to shipping or personal home use.

At the moment, if you want a purpose built rosin press, d-nail are really it. If you want to jerry-rig, by all means (and who knows, somebody could make a breakthrough in the process!), but don't be surprised if you spend the same kinda money to get the good results as the d-nail press would have got you!

What I'm saying is I'm sure dnail bought theirs in bulk from China therefore driving the cost down for them making it an excellent price.

Im not saying they're Chinese. I'm just saying it's not impossible for someone else to do the same as dnail. Yes the image was stolen but it doesn't mean they can't do the same thing either.

I don't think it's extremely hard to get the second plate to heat up if u have an electronics background. I know I couldn't lol.

actually you could if you just combined two top plates from a standard heat transfer press and mounted a top plate to the bottom with a modified bracket.
seems to me both plates are controlled with separate controllers... at least it seems to have two controllers one on each side... to bad they couldnt combine them to a single controller....


a regular heat press with a little more time to pre heat the bottom plate with the top heater does the exact same thing for less than half the cost... the only real difference is the dnail has 2 hot plates.... with 2 separate controllers....

as opposed to a single control and hot plate.

So a single plate heater operation is:

Close to preheat and wait
Open to load
Close to squish
Open to recover
Close to preheat again.
Repeat

Vs

Dual plate heater operation is:

Close to squish.
Open to recover.
Repeat.

Just checking.

basically. same technology just added steps for heat retention for single hot plate models or added cost for dual plate models.

both will work obviously... but one with more cost attached... and pre order? I hate pre orders...
ive used a gecko with high quality results.

happy pressing

After your squish, about how long does it take to reheat the lower plate?

Yeah this will be my second preorder with the GH being the first I am nervouse but hope dnail pulls it off

I want to be the first on my block to dab off these SIC Dnail plates.

it doesnt take more that 30sec to fully recover... that's mainly due to the fact the plate overheats slightly to recover the heat then stabilize to set temp. regardless of if there are 1 or 2 plates with controllers thats still going to happen due to the nature of the product. having 2 plates heating only themselves will speed the process, but its still going to fluctuate some during pressing and recovery.

I usually set up a few pucks from my hammer press and while im getting the next one ready in parchment the set point alarm goes off so its usually ready by the time I am.

Do we know if the Dnail press can do more pounds per square inch than the Gecko?

since these types of thermal presses work on the principle of a lever that locks in place at a certain point they only provide "so much" pressure anyway. you can apply additional pressure if you are able to put physical force on the dnail press handle like can be done with the gecko, but I cannot provide that data.

I've done the calculation for estimated square inch pounds for my situation, but since they are manual it ends up being an estimate and no more.... not to mention the larger the puck your squishing or the quantity of them decreases your pressure since it must be divided over greater surface area.

manual lever presses will always loose to pneumatic powered pressure though.

Oh I'm sure they bought them in bulk from China in order to drive the cost down too my friend.

Still, are us end-users likely to buy from China in bulk to jerry rig our own t-shirt presses (the small ones are 50 pounds of weight each, imagine the shipping costs/logistics of organizing this!) then jerry rig our own version? If not, then this is not really pertinent to our cases.

Of course the companies that we buy all vape products from bought whatever they needed to make that product at a considerably lower price than we are charged, due to bulk purchase.

If they didn't make money to cover overheads and wages/salaries, they wouldn't be a viable business. We need to remember that people's time, research and labor are worth money (until we have some other measure of the value of goods and services of course ), and that we should not expect a product to be sold at no profit!

As you know bro, I do have electronics background too.

It isn't that hard to make the plate heat up, but it is much harder to have each one attached to controllers which accurately tell you the temperature of each plate independently. All I was saying is that if someone like me bought one of the same Chinese presses and rigged it up to perform in the same way, it would end up likely costing me more than if I just bought the D-nail beta press (of course once shipping is reasonable) without buying presses in bulk!

BTW for those who mentioned pressing with only one heated plate, my first jerry-rigged press setup only heated one plate - I would not wanna go back to that lol, especially for those who press as they dab - it is like waiting for a sublimator and its atomizer to reach thermal equilibrium when you just want to have a dab already - not fun!

@farscaper

What kind of numbers did you think the small press is putting down?

I've been trying to calculate a rough estimate, but the D-nail mechanism is more complicated than a simple class 1 lever (below).


Found this diagram online which seems to be closer to the D-nail mechanism:


So if you apply the same ratios to 25-50 lbs, theres a minimum force of 106 lbs and a maximum of 300 lbs.

Divide that by 25 sq in and you get a surface pressure of 4.25-12 PSI. Maybe my calculations are off but those numbers seem low. And when you consider the larger press (225 sq in) the numbers drop much lower.

i agree the second image represents the mechanism of a thermal press, but consider when you calculate the sq in I would reduce the surface area to that of the surface area of a single puck or coin rather than the surface of the heating plate. unless you have surface contact with 25sq in. that figure wouldn't apply... so figure a single puck is 1sq in or less that really improves the figure and makes it more realistic.
your puck or bud may vary but that is the surface area in contact between the plates so that the number I would use.

of course the more material at one time you compress the lower you lbs per sq in. will be because there is a greater surface area to cover... so if you have 300lbs of force on a 1in sq surface you get a full 300lbs of force... if you have 6 pucks in place you have only 50lbs per sq in. of force. which is dramaticly lower.

Yeah I was thinking of that but I've noticed in my various presses the plates always seem to contact, unless it's a repress of like 5+ coins, where the force just isn't enough to compress the material anymore.

I've also found that adding a shim (reducing the plate area) on some of my earlier presses significantly improved yield. I think if the pressure was totally isolated to the area of the coin, the shim would have a negligible effect.

SO...should we buy the ebay one or the Dnail one lol?

would you buy a low end base model car or a high end model.... both run just fine... both require the same maintenence and both require you to drive it correctly...

one just has more bells and whistles and one is more basic. both do exactly the same thing. one costs more than 2x in price...

its a personal choice... im just pissed im out of parchment when I went to squash some rosin last night. .. I need some parchment!!!

@farscaper -- I normally buy a good solid low mileage, used car lol.
I just wanted to hear what you just said that they "do exactly the same thing".
Now go get that parchment paper, man!!

got my parchment. now to squish.

tekmology... what is that all about

Thanks for all the help guys, my buddy got a hair iron with a digi readout, what temp should we be looking to try this at? I'm gonna dig back and read as well, apologies if this has been answered. I'll post some photo's of the results later

I think it depends a little on the strain and how much pressure you can put on it without breaking it.. Some nugs for me yield well at 220f but others seem to like higher temps. I try to stay below 250f and it seems to work good for me with my nugs and iron anyways.

Bubble. Yield was around 75%. 25u micron pressing screen. I use it once then toss.

Didn't weight in the and out. Used hair press and c clamp.

Dudes in WA are using multi plate presses. Worlds largest press?

I have two different strains, one seemingly produces nothing, the other produced a whole lot. We were using it at 370-390. Buddies have a different type then mine that produces nothing, and they get decent results from it. I think my one type is just a bit too dry/loose.

Got a real nice dab with my nice nugs, but I just don't want to press my nice nugs lol. Not bad though, and super simple. Did like 7 sec presses 2-3 times. Pretty fat dab per .1/.2

For those waiting/interested in a D-Nail Press, they posted a short update on the D-Nail FB page:

Question about making rosin from dry sift or bubble bags.

Is there any reason to really refine it down with multiple screens or bags to high grade hash if we plan on just squishing it anyways? Using just one large screen or bag and squish it all it in a tight filter and be done right?

Edit: With a 25u screen, it looks to me like your rosin is also basically dewaxed @Been Vapin ?
