From the conversation on the other thread, I'm beginning to think that a homemade version of the Tarm or Econoburn is really what I want.... I've really wanted one of those since I first laid eyes on them....... The garn is just not what I want... Neither is really a mass refractory unit like I'm currently contemplating. I think the downdraft gasifier design used on the Tarms, Eko's etc is much more efficient than either....... Has anybody seen the Stickwood Furnace plans before? I can post a link to them if you need...... It's like a Tarm or Econoburn turned sideways! I'm really thinking this is the way I'd like to go........ Anybody that has or knows of a source for plans for such a downdraft unit is heavily encouraged to post it here!
