what i'm looking for is basically a forum with an open-source attitude with people who have built their own units from scratch. i know that a build is likely to involve some tweaking and possibly rebuilding after the fact said:
Have you tried driveonwood.com? There are quite a few on that site that are building units right now including me. One of the easiest gasifiers to build (can be done almost in one afternoon) is the charcoal gasifier for running small engines and generators. there is a whole section on that website dedicated to charcoal. Please don't build a FEMA gasifier. They do work but are extremely touchy and need constant attention and exactly the right conditions in order to make clean gas so you don't ruin your intake valves with sticky wood tar.
