Could anyone explain what is meant by "split the mixture"? Split as in form two separate fluid layers?

Great build. You've really perfected your design idea here. I love how you incorporate the three leads all together at the end - so clean. I'm sure it works a treat.

It's an attractive hypothesis. But just observing a correlation between moisture and yield does not reveal a mechanism of action in and of itself. To state that work is definitely being done is a tremendous leap that is not supported by this data. Do you have a science background? I ask because...

The formula I cited refers to kinematic viscosity, which is a function of temperature. Lowering viscosity is exactly the factor that would increase flow. So from a purely flow (yield) point of view, higher temperatures are better. In practice, however, increasing temperatures is of limited use...

So it dawned on me that extraction of oils from plants is a very old problem, and agriculture has been evolving for many centuries. I did a little digging into the agricultural world and found a few interesting things (the technogy is referred to as "expeller pressing"). Rather than pressing as...

It's an Evil Monk clone. The wire came from riogrande - 200ft of 30ga for $30. Claptons use up a ton of the wrapping wire, especially with smaller gauges. This particular wire is intended for welding, and is thus super clean...

Lol no, no extras. It works amazingly well. Zero complaints as of now. I had literally zero experience making coils a month ago or whenever my first post was. Looking at the finished product here makes it look a lot harder than it really is. After about an hour or so of practice, making a fused...

Wow talk about giving the old college effort! Well, if we can't get anything other than water back into the nug, I'd say that's about all she wrote for this idea! Thanks for investigating for us @BoogerMan. Sorry it didn't pan out.

Any of these oils would work great in terms of heat transfer. Great idea! Plus the whole "like dissolves like" thing would seem to work in our favor. The downside is virtually no chance of removing this oil from the final product unless its density is significantly different than rosin oil. But...

Sounds like a great plan amigo. If you remember, try to weigh them both right before you moisten them up, then again after. Subtracting those numbers should be pretty close to how much liquid gets put into the system, which might be handy to know later.

This is probably not a great forum to be debating the safety of PG, but you raise a valid concern. It is true that under incomplete combustion, PG will yield some nasty stuff like formaldehyde. But, and this is an important but, if you are reaching temperatures that will cause such incomplete...

This is where I'm going to settle. 2x24ga Ti wrapped with 30ga Ti, wrapped around a flathead screwdriver: This will easily hold dabs of .02g (tested), and likely up to .04g or .05g without trouble - .02g covered less than half the area after being pulse-melted into the coil (I'm still a...

My guess is that there will be very little in the extracted rosin - the majority will be left in the leaves, just like the majority of the H2O is left behind in a normal pressing. Moreso if temps are below 370F. This is why I wanted to know the pre-press dry and moist weights to help account for...

Awesome @BoogerMan! You ask great questions, and I don't really have all the answers... Here's what I would do. 1) Place test nugs in freezer for a day or so. In the past my material has come out dry/brittle from the freezer. This seems like a better way of removing moisture than heat (because...

PG should handle about 1% oil by weight http://dowac.custhelp.com/app/answers/detail/a_id/7215, but your point is taken (and why I mentioned PEG 400). If the goal is oil solubility, there are clearly better choices (like butane). I'm highly curious what would happen to a dry puck that had a few...

Is anyone willing to try pressing some test nugs using a medium other than water? I have a feeling using propylene glycol (PG) to "hydrate" a bud will result in better extraction. Firstly, oil dissolves in PG whereas it does not in water. You would get the same internal expulsive force as using...

@ReggieB Of course! Heat transfer! That explains the improved results with moisture! Assuming some amount of heat is necessary to induce the flow of oils, imagine pressing bone dry material. Even once the air pockets have compacted away, the dry cellulose is still a poor conductor of heat. As a...

After a few days of using an outer wrap of 24ga, I definitely observe less capillary action than when I was using 30ga Kanthal to wrap - the oil globs on top of the coil more than being drawn in to the coil. But Kanthal tastes like poo, so I'll stick with 24ga until my 30ga Ti gets in. 24ga wrap...

Has anyone tried a "walking" press? Fold parchment so three sides are enclosed, one side open. Take the rear side and press just the rear half inch or so. back it up another half inch and press again (so one inch has been pressed total). Keep walking like this until the front of the puck is...

Latest wickless build: 2x24ga Ti core wrapped with 24ga Ti, coiled with four wraps around a flat head screwdriver. From the side: I think this is ultimately an improvement on a stacked stovetop build. Flattening the upper half of the coil prevents oil from dripping around to the bottom of...
