A buddy of mine (who's on this forum somewhere) had the old BC Vaporizer, so I tested it out. Because I wasn't then smoking as often as I had been (was struggling with cannabis-induced anxiety), I didn't think I'd buy one, so after some "research" I built one of those super-ill-advised ghetto light-bulb vaporizers. what's that you ask?
First of all - use a CLEAR incandescent bulb - not one with any kind of frosting, and definitely not an CFL, or you'll die even faster, or get some weird brain disease or something.
1. Carefully separate threaded metal portion from the light-bulb. You have to break part of the "mouth" portion of the glass after removing the metal cap, if I recall, but it's doable.
2. Clean out the aperture as much as possible. That shit's *glass, yo*, so *clean it*.
3. Find a plastic bottle cap from a pop bottle - I suspect a metal one will do as well, don't know, never tried.
4. Cut 2 holes into the top of cap, insert straw / tubing into one of them - the other hole is the air-intake / carb.
5. Seal the be-tubed hole with least-cancer causing substance you can find, if desired.
6. Thread cap onto light-bulb - don't tighten to infinity - that's a light bulb, man.
When you want to vape, you simply remove cap and add a bit of herb to the light-bulb. Replace cap. Now, freebase-style, hold open flame or heater thingy to the bottom of the bulb - takes practice not to cause combustion, but again, it's doable.
So yeah, BC Vaporizer - that was my first experience. Then it was onto one of the many Vapir models (none of which I owned myself). Never a fan of those. Then the Da Buddha (which I still own - that thing is a champ), then MFLB, then PAX1, then PAX2.
You DID ask for my whole life's story ... right?
Mid 70's After a High Times article we built a cookie tin with electronics within with a car cigarette lighter inside a baby food jar. Press button, heat lighter till wisps of vapor then release button, unscrew jar and inhale vapor without consuming meds.
A Lot of work but nice payoff.
Mid 70's? You're a renaissance man (or woman). That's unreal.
