Gonna have to go with riding high on this one. Look at eagle bills vaporizer and try to mimic as best as possible the effects with the test tubes. I was looking into making one with a soldering iron but as it turns out convection is the best vaporizing method not conduction. Basically you want to move hot air through the weed, not touch it with something hot. So the simple put a bowl on top of a soldering iron, put the weed in the bowl and heat wasn't as good an idea as I orginally thought. If you want to spend the money on a heat gun, that is one method to making these bad boys.

Another for super cheap using soldering irons AND convection style is here http://www.overgrow.com/edge/showthread/t-400744.html
I gave up on making my own, since I have the money to just buy one the proper way. Good luck though.
