After watching this video of Jason's (Jim Faulk Stove) http://www.youtube.com/watch?v=pN30_tG7S3A&feature=fvw I built three different versions and have moved to a larger size. Beside the obvious nasty looking pot at the end that needs to be cleaned. And I have tried several woods, different sized pieces and removal of bark, feeding it as shown in the video. I am dissapointed as the wood frequently smokes more than going to coals and the wind is almost a neccessity on the feed point side.
The next version will have a a double A fan somehow, small ring of holes around the top for gasification and a v vent that is lower on the top can. The bottom ring of holes will be a little higher and larger. a seperate metal sheild will seperate the bottom from the ground and a mesh screen will keep the ash from clogging the holes... A true work in progress....If you want to weigh in I am at 6 oz at the moment on this project.
