(1) is the machine constructed out of a wine bottle, spice placed on inside
Likely SWIY wouldn't necessarily have to do this, but if it were loaded from the outside, much of it would be too exposed to the naked flame.
(2) is amor_fati's bubbler found plus a test tube (SWIM saw a diag of this someplace on the nexus, can't remember where)
This was inspired by 69ron:
Improvised Labware Vapor Bubbler - DMT Discussion - Welcome to the DMT-Nexus
This one's interesting as well, and SWIM drew inspiration for his current model from it:
Improvised Labware Vapor Bubbler (continued) - Vaping/Smoking - Welcome to the DMT-Nexus
(3) is the bubbler above with a mini-machine instead of a test tube, as shown
here
SWIM never built his original model for a bubbler, but this is his current model. SWIM's going to be designing one similar to what you attached in your post (
http://img64.imageshack.us/img64/2941/adminz.jpg), but with a slightly downward angled tube to keep the oil in the plug as it heats. Also, in your illustration, the nozzle hasn't been removed; perhaps this will work, but SWIM finds it preferrable to expose as much of the plug as possible. With the way SWIY has it illustrated, it seems like it would result in overheating the glass. Also, with the spice on the side of the plug that you show it on, it will be heated too directly (it will work, but not so well as if it were loaded from the opposite side).
Are there differences in using a candle, butane torch lighter, or a regular lighter - or do they all get the job done?
SWIM didn't have a whole lot of luck with with a bic light and wouldn't recommend using a candle due to the smoke produced and difficulty in use with a machine/bubbler combo.
And, if one does not have a 2-hole stopper, is it alright to just make holes in a piece of rubber that fits as long as they are airtight?
SWIM would imagine so, but handheld hole cutting devices for stoppers do exist. SWIM's current model works like a pull-stem, but his next will have a carb using a two-hole stopper (SWIM will likely make the holes, himself).
Also, amor, why does your
wikitek lack the coils you described
here ?
SWIM's original prototype of the current model used a spring, but SWIM found that it was largely in the way when loading and simply accumulated oil without being able to heat it very well without getting the device too hot. The old models used the springs as a catch for the oil, so it wouldn't allow too much runoff to the mouthpiece and would make it possible to heat that runoff (though those devices involved much more heating than the new models). More importantly, they simply kept the plug in position, but with the new models, it's preferrable for the plug to be able to move within the stem to recover active runoff.
SWIM thinks SWIY's bubbler design is just fine, but if SWIY is going to be using an inhalation tube like that shown instead of using a flask with a sidearm, he'll either need a third hole for a carb or set it up as a pull-stem. Also note SWIM's prior comments regarding the angle of the bubbling tube.
