Happy Sunday Morning,
Clocks set, Reddy sleeping on my lap. All good. As I suck the crap outta this glorious 19/19, glass lined, bored out and peripherally perforated walnut cooling tube, I am sure that manual regulation needs its own mouthpiece. Testing still needs to happen, and people will like different things, but I feel with the right roasting tube set up, regulation becomes unnecessary.
I think the key will be finding your perfect tube set up, might even change with different strains as well as vape profiles, but this is what I'm finding from ALL my experiments.
12 mm glass insert
Huge difference in heat. This thin glass lining sucks up heat, but AFTER the vaporization process. I think it might also help the heat stay nearer the load.
19/19 taper
Huge difference in combustion potential as well as a reduction in heat felt. Overall much smoother at longer duration, lower temp hits. Definitely sacrifice some battery efficiency here.
13 mm hole bored into tapered tip
Fantastic idea to stabilize the basket screen, give it a set place to mount. I like about a 3/8 depth, can still load pretty close to the tip. This seems to give the best ABV results, cleaner, drier. This also opens up the surface area exposed to heat, and allows you to load a bit more product. We are also talking about trying out a 14 mm hole.
8 small holes drilled around tip circumference (1/8 or so from tip)
I wasn't sure about this one, but whether it just removes wood and allows better heating of herb, or it provides better airflow, it seems to extract nicely, keep airflow wide open, and reduce combustion potential.
Hemp added to glass
Keep this light, don't overload. A small ball of hemp in the narrow glass tube can be very effective. I find with a brand new set up, this can dampen things down a bit.
SS foil spiral added to glass
Yet to try, maybe today...
My testing process has been simple. I've applied one, two, three, four, five of the above on various tubes, as I've vaped throughout the day, and the one that one that I keep coming back to, most user friendly, coolest, best taste, strongest effect is using everything but the hemp. The hemp works well, but optional. I like how this combination kind of loosens up the process, gives me a bigger window of spectacular vapor with less effort, and concentration. I can do it while I'm typing here or in deep concentration about something else.
I think the distance and glass do that for me.
@SnowDome @Alan makes them, and I should be getting a bunch from him soon as well.
