Please keep in mind my illustrated transformations of the VaporGenie pipe(s) will automatically void any related warranty; the terms "Prototyping Platform" and "DiY" imply some models (Classic Wood/Aluminium and/or Bronze Sherlock) have been selected in order to refurbish their key components and reconfigure them, the owner always assuming all consequences for his actions - not to mention this is no invitation to create cheap clones as i must insist the original/patented intellectual property legally belongs to Dan Steinberg, inventor and company founder.
The purpose of my customization tips is to offer VG pipe owners something that ain't even available in option, like a rare opportunity to explore Pulse-Heating (and more...) via implementations of VG's long-forgotten Fig. 11/12 item, which in Egzoset's Hybrid Core (replacement) layout actually corresponds to this "17-holes Metal Disc" as described below, with tiny thermal side-pads included:
Technology only got better since the Y2K bug, although it already was space-age enough to use "Duocel" Silicon Carbide Foam we could have wished VG's patent also covered electromagnetic Induction Heat applications, while IH-drivers got time to improve during the last decades... For many years now i've demonstrated my "Plan-B" operating mode of a Bi-Energy concept, where "B" stands for "Clean-Burning" butane; so "Plan-A" only needs to build on what's tried & tested, except there ain't going to be Inlet Water unless both IH-driving + butane combustion get combined simultaneously somehow. M'well, such a scenario remains possible because VaporGenie's material selection allows it conveniently, as SiC Foam routinely supports exposure to extra-hot exhaust (H2O + CO2) gases in their genuine pipe design to begin with - which is the main reason i picked a VG pipe in the 1st place, since i knew from experience that i couldn't stand Hot Dry Air Ovenizers on the long term.
Once switched to Full-Metal tops (to accomodate "Power Micro-Bursting" with multi-jet torches), after all the hybrid core-tweaking was done, it turned out my customized VG pipe seemed finally ready for yet another feature which translated into one major contribution eventually, e.g. the Direct On-Top Core-PinHole path (painted in cyan-blue below):
This fresh-air injection path is directly linked to the heart of my Hybrid Core structure, split-path configurations support manual control either using a fingetip resting site/hole located on the top itself and/or on the handle, one not totally disabling the other as the manual aspect survives even in presence of a permanent PinHole path (apparently it's the "pumping" action or pressure transitions that matter most in promoting cloud movement)... Below this is a modified (cut & drilled) "Monobloc" with its Hybrid Core components on the side, starting with my "SiC Front Puck", then the "17-Holes Metal Disc" (and opt. susceptor), then a Brass Screen wrapped "Top-of-Bowl SiC Puck":
It's the very same terminology i used to refer to since my late 2015 "UFO Element" tests or so i think, i was done adjusting core ratios a couple years later:
As for the PinHole it forced me to reflect on the problem of a universal system capable of maintaining backward compatibility while also giving optional access to new functionality:
My "DeLuxe" scenario would most likely depend on Electrical Discharge Machining (EDM) to craft a hole (or 2) through the Monobloc material, by chance i developed a much more accessible alternative as it's only requiring a drill accessory just as pictured right next:
Despite what's shown here exactly it will be essential NOT to cut all the way down (e.g. until no flat annular mating surface is left up to the rim), instead a containment mark needs to be traced around the Screw Base with its (Classic) bowl (~18.8 mm dia.) still attached, clearly visible in red:
Diameter of the cutter wheel is equally critical as it ensures nearly-ideal alignment inside my final Hybrid Core, as both the internal (Direct) and external (Auxiliary/Handle-side) PinHole paths must meet together past the 17-Holes Metal disc, with provisions for a maxinum of possible cust. VG pipe permutations:
One even more accessible method had 1 single cut at most but this rendered my PinHole permanent (with core fresh-air injection at all times):
So lets prefer my "Easy-Made Universal Split-Paths Twin-Cut On-Top Core-PinHole System" for its lesser trade-offs... And by the way, take note a core Metal Disc can be substituted with ordinary screening of equivalent heat retention, hopefully with light impact.
So this slightly more involving "Brain-Dead" solution just requires 2 "twin" holes to be PUNCHED THROUGH a thin residual metal layer left at the edges, with force applied at an angle from the Flame-Catcher (left) side:
Doing so shall feature the Top/Sphere with a fingertip resting site most useful when installed on a Bronze/Sherlock handle (left), because it can be aligned to fall under with my index finger:
The Classic Wood/Aluminium setups can also benefit from a manually-controlled Core PinHole path but the best possible choice involves a Classic Aluminium configured like this:
Where PinHole #1 might correspond to "Pump" and Pinhole #2 to "Pre-Heat", depending on internal routing...
Too bad this level of handle customization ain't as accessible as for my tops, YMMV.
With "Plan-B" sufficiently perfected the next big step will be to try Induction Heat at last, possibly using an IH-driving mode that can provide Back-EMF feedback to "close" a control loop for overheat prevention (unless "Curie" alloys can be found). Anyway basic ferromagnetics will behave similar to what's suggested below:
Absolute readings may be difficult to achieve but i still foresee a fair opportunity to gain near-linear response via some relative setup that depends on training cycles, for example.
Yet i believe one might want to check with Stainless Steel 430 or similar, as that's food-safe and also highly "magnetic" (not just conductive). In any case my initial plan relatively to IH driving was to limit involvement to more "KISS" solutions, for example by reshaping the coil of a ready-made 3rd-party commercial product like an IH cooker base:
This shape required the load to equal or exceed the diameter of a Compact Disc, my susceptor only measures ~12.6 mm in comparison... The "Skin-Effect" of eddy currents from radio waves in the higher frequency spectrum would become a nuisance in presence of other conductors as the aluminium Flame-Catcher bloc, it energy injection must be targetted then a magnetic drive makes more sense than an electric one. So i'm presently gambling on Full-Metal tops but might have to conclude these must be glass or ceramic. Que sera, sara!
On the bright side there would be plenty of power in Pulse Mode to "Spot-Heat" a 0.75 g susceptor or even a pair of them, as imagined in my LAVACapsule many years ago:
The purpose of such capsule symetry is to support quick in-situ reversal to perform Reclaim/Maintenance (with sealed center section cfg.), or even experiment with 2-Stage Heating à la Sublimator where post-vaporisation substances gets submitted to re-heating, either to cause the microscopic airborne droplets to shrink further in size (so to pass the lungs/bloodstream barrier with more ease), or perhaps to "activate" the cannabinoïd precursors or even both. Only experimentation can tell and there's more to toy with, like perhaps Heat Vectors "defocussing" via a 90 ° change of direction inside the bowl itself (with cloud collector in the middle), and/or mechanical stiring from vibrations to maximize thermalization, or a combination of Induction Heat and Inlet Water in enhanced "Micro-Bursting" mode with better precision "Packetization" or dosing, etc.
In a perfect world VaporGenie would take possession of my donated conceptual extensions and turn it into their own "trilogy": #1) One single pipe already improves butane-based performance significantly; #2) Two pipes would enlarge the applications range by allowing tops to get swapped around (each top-specific Heat Charge matches its bowl Workload); #3) Two pipe sets and an IH driver would implement "Plan-A", perhaps eventually with "DeLuxe" options as Self-Moisturization and "Potentialization" of the "Release/Transport Agent" from "Potentialization" by extra-hot exhaust gases, etc., etc. Briefly put enthousiast VG owners would start their collection by acquiring 1 single most affordable pipe and decide if it's worth an escalade towards IH technology, e.g. turning previous spending into an investment for the future...
Total mass of a minimalist 1¼" (dia.) LAVACapsule ranges around 100 g, meaning the magnetic part only represents 25 % of such mass while its susceptor(s) shall translate as 1 ~ 2 % at most. Consequently using enough power it must be possible to inject some temporary-storage "Heat Charge" (near a hundred Joules) in a matter of seconds, with plenty of time for the core to heat up though far too little time to raise the whole capsule temperature so high it would risk becoming a skin-burn threat: e.g. it's going to remain safe as long as the LAVACapsule ain't working in thermostatic mode, in opposition to Hot Dry Air Ovenizers where material selection is more complicated if we consider those get intensely hot for long minutes instead of brief seconds.
So the rewards i promise are multiple and unique, like to experience Pulse Heating not previously accessible using even a genuine VG pipe. The main trick is to separate its "Pre-Heating" (#1) and "Main" (#2) phases as two processes made as independant as possible:
This involves enough overlaping in "Plan-B" mode to feel more like an approximation (with somewhat blurred boundaries) than digital precision as expected for "Plan-A", yet the "window" it opens is sufficiently valuable to justify the cost of such "Prototyping Platform" all by itself IMO! My regret is that i can't be so confident to claim i'll be able to evaluate "Plan-A" personally but i keep hopeful nonetheless. My LAVA challenge being modular this garantees at least an excellent "Plan-B" at a most affordable price.
Good day, have fun!!
