Dual heating hair iron or tshirt press? You see the hand clamp extra step on youtube yet? Its just a sheet metal tool that squeezes out more oil than the hair iron by itself. Pretty neat.

Nvm found dual heat irons and rosin tech screens for like 5-15$ on ebay. 25-50 Microns woo

It the t 5x5 -15x15 tshirt preses. Dual heating plate . Same machine on rosintech site s just for instance th 5x5heatpress on Ali baba is 139$ on rosin sites same press but custom painted with logos an it's 390$. I m good with the all black for 139$ . I understand a good mark up. But only on the rosin preses that are actually built for rosin not the re purposed t shirtpress.

My 1 ton rosin press has cost me $120 and is based on @chuck estevez design but with less pressing power than his. I tried to attach the bench blocks with JB Weld epoxy rated to 550 degrees. This was inadequate and the epoxy failed after about one hour of use. So I'm getting a buddy to weld it up proper. Big fun!

How much pressure does the t-shirt press have? If similar to my 1 ton, that would be the way to go at $139.

ha ha, you could have mentioned it! Now I'm trying to get the shit off. I don't think freezing the blocks and banging them is going to work so plan B will be to blast them with heat. Plan C is to soak in acetone overnight. Any tips?

Sounds like a deal to me! Good luck and I'll look forward to hearing how it goes.

I found the tea bags do not hold up under higher pressure, anybody else find this? I cut up some 45u cloth into little baggies and they worked fine, but a pain to clean. I'm trying out 50u stainless steel mesh next time, probably next week now. Anybody got a good screening solution for easy cleaning on a 4"X4" press?

There's no way that 5x5 press is 3000psi I have the same one and it's not that much at all I don't get the greatest yields from it. I'm thinking of getting a arbor press and taking the heat plates off the press I bought and modding them on to the arbor some how. Just trying to think in how to do that.

My $15 4"x4" steel bench blocks all have a good 1/64" cup on each face - not really surprising but something I hadn't thought to check on until I sanded off my failed epoxy experiment. After about 5 minutes lapping them on 80 grit paper I got the cupping down to a tolerable level.

Just heads up on presses. Found the Same presses with dual heating plates even pneumatic ones. At least half price as any "rosin tech " company offers. Check Ali baba .com they even list as rosin press

This caught my attention, really considering this, alibaba sketches me out though

Here's my take on the arbor press idea....don't know if it has been covered like this...My apologies if it has :peace:

Harbor freight has a 1/2 Ton for $40

Infamous $15 PID Controller




2x K Type Thermocouples
[something like this is fine, but just make sure to know whether it is grounded or un-grounded...if it is ungrounded, a ground wire can be added simply. ]

Maybe some of you know the wiring aspects of this, but for those who don't.......

This a pretty basic setup based on a Solder hotplate...looks something like this...

Put It All Together

Hopefully, you can see how the press block is drilled and the cartridge heater pops inside....

Each block gets a cartridge heater and a K-Type Thermocouple...The PID controller monitors the temp of each pressing block's heater thru the K-Type thermocouple, for those who don't know.


Personally, I plan on just using a 3" x 3" x 1" thick piece of steel plate...Use the drillpress to make a hole in each press block. Then stick weld the bastards to the Arbor drop arm.

If you really want to get fancy, you could use an Arduino Uno R3 $10 and a 30A SSR relay in place of the PID controller...then bluetooth the bitch.....



This PID controller could be "hot-swappable" to a DIY Enail..too. You would have to make your thermocouples removable along with the Heater cords or adapt for a 5 pin SLR, to really swap from Press to coil...

anyhoo...fuck, that was my contribution for the week :peace: :joint:

It would be cheaper to buy the arbor rosin press from high 5 vape. It's $349. 1 ton arbor press with 2.2 " cylinder plates. 526 psi

Cost the same amount as just buying plates and a pid and wires

I would be far cheaper to make your own 1 ton press than to spend $349 on one. Mine was $120 and it looks like I could have done it cheaper from some of the components that @Abiqua identified.

A good pid controller alone will cost over $150. That cheap $15 will fail. And then you have a fire hazard . Plus the plates and mounting brackets and wires. To buy plates already made costs about $200. You want stainless steal or silicon carbide. To have them made will cost even more.. sic plates will be even double.

If you buy the harbour freight press. You will spend another $50 replacing parts.
