Hey All, In May 2011 I bought myself a PD and love it. I have noticed while the craftsmanship is appreciated as top notch on most (if not all) log vapes; there are valid reasons why people would want to build their own. Eg shipping times, customs, wrong power transformers, satisfaction of constructing one ... I was wondering if anyone would be interested in collectively putting together some free plans for building a heat exchanger and installing it into a "log"? The goal of this project is not necessarily to improve the design but to make having a quality affordable vape available to all. I was thinking a list of materials, where to get them, tools needed, some designs, and pictures available for free in a download-able format?
