Dabpress Rosin Plates

@somerandomguy1 Are you sure it has oil? If a bottle jack is shipped on it's side, sometimes it will leak out the oil.

If you are sure it has oil, very often bottle jacks have 1 or 2 screws at the base near the pump action that adjust the flow in and out. They need to be balanced or the jack won't stay tight.

Pump it up all the way and start adjusting one of the screws as you pump. One of the screws will adjust the flow so it's balanced.

I have that press but with the 12 ton pump and my setup went smooth as butter. Sorry to hear your setup is not. You might want to check out the 420vapezone discord, maybe someone there had an idea.

That's the downside of buying from a company overseas, communication is never as good. Pricing makes up for it at least.

So turns out the pump is bust. They are going to refund me the cost and send me a referb 12ton pump for the cost of shipping ($25). Such but not a bad deal at least. At least this proves i'm not crazy after doing the same bleeding steps like 50 times.

This a unrelated question possibly, can someone explain the square ft = correct pressure formula to me possibly.

I'm using 14gr bags the surface area of the bag = 4.9 inch the press can do two at a time 28gr, would I press at the same pressure for one 14gr bag or double the pressure since it's two in there? Any help or info of sound value would be greatly appreciated. Thank you in advance.

(PSI from Gauge x Jack cylinder area) / area of load = PSI on the Puck

E.g.

3,000 PSI x 4.37 (square inches of the cylinder of my BVA jack) = 13,110

What do you all consider to be low temp for a press? How low are y'all still getting productive yields?

Overall, Ive found 200F to be the best/happy medium for flower at 62%rh
Dabpress 10-ton, Drip Tech,120 micron bags, 1 minute warm with a +/-3 minute slow increase in pressure, approximately 3500 on gauge max. Any more pressure than that and bottle tech bags blowout.
I premold 7 grams(max) in a Dabpress Tube Mold. Puck Inserted into a 2x4 120 micron DabPress tube. At this point using Reynolds brand Parchment.
This particular strain, Moby Dick, yields on average 15% return. One+ gram Rosin from a 7 gram flower squeeze.
Dependent upon Strain(and portion of plant, Larf, Mids, Tops) ive gotten from 8% to 24% return.

66c/150f with 12% return, 60c/140f with 11% on buds that usually (at the time) returned 17-19% @95c/203f.

I used to aim for about 180f at the plate when I was hitting ~22-24% but that was with perfectly sticky flower. Press has just been gathering dust for the last year though as everything I have access to all seems to be super dry cures for smokers

Well after formulating as best I can as I'm still not sure if you double the pressure for two bags, I'm going to be running 2 3 x 6 bags 14 grams for 28 grams total each bottle tech style on 4 x 7 plates at 198 F at 2200 pressure.

A bit about me so you know I'm not a L7.

I've been growing making my own strains since the late 80s, Pink Panther, Ghost, Crumbletooth, I moved locally until 2010 when I had some trouble come my way unbidden and had to move from the west coast to the east. I recently became free to once again get back into it had my beans/strains on ice all these years since 2010 they popped like champs. The 1st new grow should be done in August.

I'm a old BHO pro, but getting back into it after 13 yrs I had to upgrade my knowledge base and some of my equipment and this Rosin pressing I believe is the future of extraction. So I'm new to it but not to growing. Hopefully I'll pick up everything I need to know for a optimal press by the time it's ready from those more experienced in pressing here.

Thank you for sharing you knowledge of it and experience with me. I appreciate it greatly.

Is the surface area of the puck(s), subjected to the plates, changing?

I.e. suppose you use one of these pucks at X psi. If you used 2 the same as before, side by side between the plates the area subjected to the plates has doubled, in which case you need to double the pressure on the guage to get the same psi at the puck. If those 2 puck's sat on top of each other then the area subjected to the press stays the same, so the guage pressure stays the same as scenario 1.

The guage pressure, only reads the pressure in the pump. If the pumps internal area is the same as the size of the puck, what the guage shows is what the puck sees. If the puck is bigger than the piston, then the effective pressure at the puck is reduced at the same guage reading, by the difference in area.

I hope that makes sense.
