Well i've been lucky, as if the stars aligned...
This time there's yet another topic to present, because today i sort of feel some growing fear inspired by the powerful vertical drill. But lets 1st chain with a continuation of my previous illustrations:
That's about removing excess metal left between cuts, using 1 more hole-saw tool of ¾" (dia.), since it seems i failed to find overlapping units, and i wasn't done just yet:
You see, a « RECESSED » screw-base junction was in the plans, so it finally also required me to find a 15/16" hole-saw to enlarge the cavity so a Monobloc will eventually fit it (shown in reverse, up-side-down in center of image):
My middle-right Monobloc is the "DeLuxe PinHole" configuration type while i thought the bottom-right older cut-through version would never prove actually useful. But thanks to such tight fitting maybe i can refurbish it and render that lazy solution at least viable if absolutely necessary. Always keeping backwards-compatible compatibility in mind... So here's the result:
And, by the way, this was an opportunity for me to recycle a previously "rejected" piece (see right side). Now the recess cavity is quite ready to receive it's Screw-Base counterpart, with the Monobloc inserted inside once i've finished removing core material at a later time.
Meanwhile, i realized i wouldn't be using a plater vise for my drill press. Instead it seemed safer (and much more affordable...) just to build some custom-made support still intended to secure the rotation axis, which needs to be a top-priority in such involving craft. By chance the plater happens to be featured with a concealed recessed cavity defined by its 4 edges under it, so i was able to cut a piece of wood that fits tight in there, with 1 strong ¼" (dia.) screw in each corner to prevent horizontal (x, y) translations, as any movement could prove catastrophic...
Then one small problem remained considering the piece would be left to spin freely, although tighly restricted along the rotational axis:
Which is nothing a strip of electrical tape can't help to fix (...):
Special caution remains mandatory and now both hands can stay outside the danger zone, ready to switch power OFF...
Notice the round edges of that particular piece, my former "Reject" put to good use by experimenting this alternative scenario. Of course using only sand paper won't make it spherical without enormous efforts; it's demonstrated to some point that suggests a ball-shaped profile is attainable, just not for me today - but years ago it could have nonetheless!
Too bad the inventor and manufacturer actually holding the VaporGenie patent couldn't see development potential this far.
At only 22 mm high a VG Full-Metal "Top" will allow some significant shift of the pre-heating phase toward the radiative-mode vector of a flame, diminishing exposure to convective-mode « Inlet Water » and also butane-related "contaminants" in "Plan-B" mode, while "Plan-A" induction may penetrate the assembly far enough to succeed to inject IH energy as a dry-but-clean & "packetized" power substitute, paving the way to precision dosing and more.
Thanks for any sign of appreciation, please pass the word!
Good day, have fun!!
