I am wanting to build a oa vaporizer, I have looked at all the ones on the forums, home built and store bought.
Does any one have the demensions for the head. Width, length, depth. I have some 1/2 x 3 inch aluminum bar stock that I think would be perfect to mill one out of. But the size of the cup and how much width to leave for the glow plug for best heating eludes me.
If someone has a drawing with measurments it would help tremendously.

Thanks Randy
