Salutations everyone,
Six months: i suppose it's about time for a concluding review, at last.
...
Well, my modding venture started with this post:
Not much has changed externally and i'll handle the internal modifications somewhat later.
So, now that i've been using a thermostatic table unit almost exclusively for the last week i only wish to renew my expression of enthousiasm for the VaporGenie concept!!
...with suggestions on how to improve it further.
But first i must insist on the pleasant/satisfying aspect of this consumption mode, or at least once optimized for those like me who appear to require it - because, lets face it: the VG Classic failed to work as sold in my particular case; modding allowed me to render its operating range more compatible with my own comfort zone it seems...
Anyway, i've found the perfect Plan-B:
1) Convenient time-tested power source
2) Self-Humidified (butane burning => heat + water vapor + CO2)
3) Easy access to intense Aroma/Taste perceptions
4) Economic operation (125 mg bowl)
In short i find it's ideal for "sampling" missions!
Now, the modding part...
Instead of seeking an exact winner recipe i got satisfied with the last configuration enough to leave it there. It's simple in the end, metal located directly above a bowl will behave like a secondary heat source and may radiate so much this would cause more concern instead of just fix the problem it's meant to avoid. Metal = Radiator, finally it wasn't such a good idea. Have a fine screen hold cannabic herb in the bowl and put some air cushion between it and your heat-exchanger assembly which could be structured as follows (this hasn't been evaluated): 4 discs, 2 foamy-rock materials of different density... A pair of denser discs with an air path around the center would obscure the focal heat point while promoting circulation near the edge. Dense correctly aligned tripod-shaped pieces would have a circulation profile meant to delay formation of a hot-spot, effectively preventing combustion for all practical purposes. A pair of more "aerial" foamy-rocks shall wrap it up nicely. So, 4 discs is all it takes overall, 2 of them being shaped to include some amount of air cushion in a final implementation. The front puck needs to be 4 mm thick since less will let the light pass! I like 5 mm better. This only leaves a mere 2.5 mm to distribute over the other 3 pucks, which is clearly insufficient - but i found a solution: install one in the smaller bowl-side aperture (of the ball) instead. This later setup would even save ~0.1 mm over the genuine VG Classic product.
To recapitulate, if i could try it myself i'd want a 5 mm thick standard-density (e.g. "aerial") VG "ceramic filter" for the front puck, followed by a set of 2 denser/more opaque 1.2 mm thick partial discs (e.g. with hollow areas cut to favor a "defocussing" effect), ending with a 1.2 mm thick standard-density ("aerial") bowl-side VG rock separated from cannabis by some air layer and then a metal screen... Outside, an articulated "S" shaped extension "trainer" tube should provide eye-contact as an option since this can really speed up learning, if not simply render it possible at all.
