Hi guys,
I just discovered a way to make a cheap convection vape. Mine cost around 30$, if i count everything, but i had most items already, and the vape is as good as a professional one. The only difference I can tell is that mine has a metal element (from a soldering iron) and a fancy one usually has a ceramic element.

materials:
-cheap soldering iron (10 $)
- 1 test tube (pyrex) a little larger than the shaft of the soldering iron (85cents)
- one pyrex funnel ($12)
- 3 feet of medical grade plastic tubing (cheap)

(these last three things I got from a labratory supply store.)

1) cut off the end of the test tube with a cutting wheel on a dremel, this actually is very easy. now you should have a glass tube, a little longer than the length of the soldering iron's shaft.
2) find something with which to prop up your soldering iron. (in my case, i had a scafolding ground plate with a vertical pipe, just the right size to stick the handle of the iron in it. Eventually I plan to build a box for it, and cut off the handle.)
3) remove the tip of your soldering iron.
4) stick the glass tube you made onto the solderiing irons shaft.
5) stick the small end of the pyrex funnel into the end of your three feet of medical tubing.
6) stick some bud in the deep end of the funnel,
7) plug in your 'vape'
8 ) place the funnel on top of the test tube. (it should be high enough away from the element, so your weed doesn't touch.
9) inhale
10) exhale

the bud does not touch any metal, only glass, there is not even any screen holding the bud back because, the pyres funnel is pretty narrow.The weed is suspended in mid air, and only gets hot once you start sucking air throigh the glass tube (around the element), which heats up the air. The shape of the funnel, insures that there is a perfect fit between the two glass pieces. Eventually, gotta add a dimmer as this thing gets too hot...

I've made some dome-style vapes before, and this is just a million times better. the mist is so concentrated and pure. nothing is wasted. you suck everything out of that little piece of weed. very efficient.
