Still Variation
If you decide to build then it is easy enough to build a still that allows for some upgrading along the way. I will make a few suggestions here as I have built a few columns of my own. I have built a similar version of the essential extractor models and it served well as both Pot and Reflux. I can easily get 80% + on a single reflux run and 89-91% on a second reflux run. With no reflux cooling and no packing it works great as a pot still. The other type is the BOKAKOB mini still. This is a very easy still head to build and plans are in the group data base. It also works great for both Pot and Reflux.
