Pouah! Ah! Ah! M'yeah, i was inspired when i walked into our local stoner shop that day.
Nah, i ain't involved into much DiY these days, if i did this prototype would have been featured with a 2-fingers (manual) PinHole sytem and weight even less...
My DiY part was implemented long ago and been in service since when my Hybrid Core configuration "crystalized", in 2018. The CoViD-19 pandemic slowed me down considerably, i could still experiment with other aspects like optical probing (as supported in option in this illustration), etc. Basically it's an easy measurements-less transformation of the pre-existing/patented VaporGenie Classic: perform a contour mark around the bowl itself then double-cut the Monobloc's Screw-Base until half-way to said marking then punch 2 tiny holes where the metal is thin and deformed; the internal PinHole alone makes some huge difference, especially if operated manually instead of permanent. Core reconfiguration only requires a 46 TPi saw-cutter to split its SiC Puck as two, so a sandwich structure can be created where to insert the long-forgotten fig. #11/#12 item of the original patent by Dan Steinberg: a 1 mm thick metal disc with 17 #53 holes in it in my own case, or perhaps just screens or even thin air as a spacer. YMMV.
The fun part resides in operation which is nothing like the slow/steady method where materials selection becomes problematic as a result of the intense/extended heat exposure, while this pipe is cold most of the time except for a brief transition after storing a temporary reserve of heat in its hybrid Core, someday open to using induction, presumably. Etc., etc.
Overall nothing new to get utterly excited, just reminding the reader i've yet to see brave adventurers willing to independently duplicate & peer review. It's worth every bit of the challenge and the VG pipe ain't really expensive at all. The Bronze Sherlock handle offers more accurate operation but it falls heavily, a Sherlock made of this high-temp. plastic right from VaporGenie themselves would make sense, if not a water-toy adapter as with the former Lotus (now a Vapman)...
Those concerned with heat + synthetics need consider the hot cannabic stream exits a VG Bowl (metal) aperture, away from all surfaces, and hence cooling results from instant expansion entering the larger cavity (past that smaller one after the bowl). Actually i've attempted to torch the material and hardly left a mark on it, so as a "Plan-B" that's no trade-off difficult to make. In addition, the original bong was over-weight/over-size so i cut more than half the extra waste, to make more room in my kit's transportation pouch.
Last but not least i've hidden a double-trap in my photo: there's already a storage container built-in (but it's not visible because it seals the bong cavity inside at the base) and even my Customized Full-metal VG "Top" fits there too, since its plastic cap base is also amovible anyway...
In short a fun project for the afternoon.
