@psychonaut so your calculating a 2” x 2” puck under 1777psi on the gauge is 1000 psi on the puck?

You also mentioned to keep the gauge at 600-800psi ?

Im a bit confused around sonFor hash you recommend 1777psi at the gauge or 600/800psi? I would probably feel it out anyway but curious about what to look for roughly on the gauge cheers

I know it's confusing. Basically the pressure gauge is measuring the pressure inside the hydraulic system, the cylinder's effective area (2.25) is the bit of math that actually translates the pressure in the line to the actual pressure delivered by the cylinder.

So in order to have an idea of how much PSI you are applying on the bag, you need to know the puck size. Otherwise you're only measuring the total force based on the gauge reading and the cylinder effective area.

So we have to break it all down, and having predetermined puck sizes such as what we get when we use a pre-press mold, we know, prior to pressing, what the puck size will be. Our 30mm pre-press mold generally will squish down a puck about 1.75-2" diameter. So to use that as an example, 1.75" diameter puck is 2.4 sq/in.

Alright, so we know the puck is gonna be 2.4 sq/in, and we wanna apply 1000 PSI to that. We need 2400 total pounds of force. Ok, so to reach 2400 total pounds of force we have to divide 2400 / 2.25 = 1066 PSI on gauge.

So long as you know your surface area of your puck, you basically just do this math -

PSI desired x puck size in sq/in = total force needed
total force needed / 2.25 = Pressure on gauge

1000 x 2.4 = 2400 total force needed
2400 / 2.25 = 1066 PSI on gauge

Square/rectangle pucks are easier math, L" x W" = sq/in
Ex. 8 sq/in puck (2x4")

1000 x 8 = 8000 total force needed
8000 / 2.25 = 3555 PSI on gauge

Pressing hash, the 'right' pressure will depend a lot on your starting material.

Just start with a low temp when pressing hash, and build up pressure slowly.

And make sure to double bag to prevent blow-outs

Play with it.. And you will have fun

Cheers bro low and slow double bagged lol. yeah I feel it out and keep an eye on the gauge and report back. Time to start keeping records.

The little that gets lost in the second bag is a little price to pay in comparison to having to clean up blow-outs.

Also, remember blow-outs will need to be collected, then rebagged, and repressed. This will definately lead to an end product of less quality!

Its just like he said ^^.

I want to buy a dabpress but do not know which one of this four:

BTW I am gonna press for personal use...

dp-bj3t33

https://www.dabpress.com/collection...-ton-hydraulic-jack-rosin-press-dp-bj3t33-pro


Dabpress dp-bj6t35 [ Upgraded Model ]

https://www.dabpress.com/collection.../products/dp-bj6t35-hydraulic-rosin-press-kit

3x5" Driptech Hydraulic Rosin Press

https://www.dabpress.com/collection...-rosin-heat-press-machine-strongway-hand-pump

3x3" dp-bj3t33 Small Rosin Heat Press Machine - Single pid

https://www.dabpress.com/collection...rosin-heat-press-machine-driptech-intergrated

As mentioned before it is for personal use...
my problem is I want not to sacrifice in return losses (efficency - getting less out of herb then with a better press) and also not in quality (terpenes, purity and so on) regarding pressing rosin... but I also do not want to spend money for what I do not need for my purpose...

Thanks for your interest!

If you must have a gauge there is only one option. I try and ask that question first as some people don't want a press without a gauge. If a gauge is a make or break, hr10t35v is what you want. It's way more than what you need however. This unit is capable of pressing up to 28g buds. It also requires the purchase of a pump separately.

If you have no preference either way on the gauge, either of the bottle jack units are fine for personal use. The bj3t33 is suited well to <7g of buds, and the bj6t35 is suited well to <14g buds. Both units use the same basic technology of a bottle jack to deliver the pressure needed, and both have driptech capabilities. I generally recommend the bj3t33 unit for customers who dont plan to press more than 7g of buds at a time.

We are currently sold out on bj3t33 unit (the pro model is available, the difference is independent heating of plates as it has 2x PID's). Hope to have restock after the Chinese Spring Holiday starting early next month.

As far as efficiency, it really depends your puck size. I recommend around 1000-1200 PSI for pressing buds. 1 ton = 2000 lbs, so you can figure the max surface area for pressing like this -

3 tons = 6000 lbs = 1000 PSI on 6 sq/in pucks
6 tons = 12000 lbs = 1000 PSI on 12 sq/in pucks
10 tons = 20000 lbs = 1000 PSI on 20 sq/in pucks

thank you!

I do not know if I realy need a gauge to be honest...
would I get better results with a gauge?

Nope, it's helpful for sure, but you can get a feel for the hydraulics pretty quick. The effective PSI range for pressing is fairly wide, so being 100-200 PSI off wouldn't really translate to huge difference in yield.

I normally tell people to run 3.5g to start, press it slowly, count your pumps you apply, so you have at least something else to base it on aside from feel, then watch the rosin flow, notice the color, watch the color as you begin to apply more pressure. Once you see the color change to a noticably darker shade (may even have dark green tint), you've pretty much gone too far in pressure, so next time you do a run, go by feel, and also count the pumps, stop short of where you got the dark color on the previous run.

I think personal pressers really dont need a gauge as they are pressing so often they quickly become proficient with the unit.

I have to also mention, when it comes to making dabbable rosin, while you may feel like you didn't get it all out, it's true, you likely didnt, so if you are also an edible or tincture consumer, you can wash those pucks for usually 1-3% extra yields. Saving them up for later use in those forms is a great way to extend your medicine and truely get everything out of it.

If you don't care for those other methods of medicating, you can always repress the pucks to try and get the rest out, many do with great results!

Thanks, @psychonaut, just a suggestion. It would be a nice kind of CS by DP to write a little - downloadable - programm for calculating the PSI and publish it at their site. In addition it would spare you to describe the steps of calculation again and again.

It's a good suggestion. Perhaps a pamphlet included with the press to show the customer how to do the math on their smartphone calculator. Some simple pictures or screenshots would make it clear.

Dear FC friends and Dabpress family,

Roger has informed me that the Spring Holiday for China has already begun. China freight companies have halted operations until the holiday is over. DHL has halted operations from Jan 30th - Feb 11th.

During this time, we will be taking factory direct orders as normal on dabpress.com, but processing your shipment once DHL resumes operations on Feb 11th.

We have a limited selection of products on Ebay or Amazon/amazon.ca which are already in US or Canada warehouses. Those purchases would be fulfilled as normal.

Thanks for your patience during their holiday season!

I grind those pucks very fine and vape it with the herborizer ti. This works much better then i had expected before. :tup:

That sorta sounded like I should give pressing w/out a bag another try, just to try post press vaping !

It's possible to dissect the puck out of the filter when it's fresh off the press, then you can save up the filters to wash down the road if they have any residual oils on them. I know a guy on reddit who's actually reusing his filters, seems to be working fine for him too! He's infact a member of this forum, just not sure if he's posting yet @SquishSquashDude

I’d love to hear more about the reusing of filters, that seems to be one of the biggest recurring costs. Hope that @SquishSquashDude will drop by and share his techniques since I don’t go to reddit. Great to see so many new owners out there!

Hopefully he'll pop on and respond, from what I gathered, he was pressing hand stuffed filters, or 30mm cylinder pucks layed side by side inside a 2x4" filter, not sure if he was folding the corners in or not, but I think a filter that's been pressed flat (aka not bottle tech style) would have the best odds of being reused.

My only concern is if the filter is pressed too hard, it will likely stretch the mesh so it's no longer uniform microns. But for someone who doesn't care for filters either way it sounds like a perfect money saving solution!

Hello All
I picked up some Black Diamond. great berry aroma. Very nice color.
So I did 28g. Hand stuffed in to 3 separate bags so 9.3g per bag. 2x4 bag and I used the hole bag. temp was at 230F.
I took my time to put the psi up. You can fell when you need more pressure. Gauge is very helpful.
Time was in the 5 mins it would not stop coming out .LOL
I even took the line PSI to 4000 to get it all it did got a little darker.
But not so much. Not like others I have tried, and with it at 230f.
Return 6.3g. 22.5% Great taste The colour was still very light even with the high heat.
I have the 10 t 3x5 plates.
Loving every second I use my DP.
