First of all my apologies to "donthaveoneyet" for hijacking his "Cat Can Stove - Questions" thread here: http://whiteblaze.net/forum/showthre...tove-Questions
This is new thread to continue the discussion of the CHS (Capillary Hoop Stove) and constructions techniques
BB, thanks for your description. I am definitely seeing "bubble bomb" and excess thermal feedback in my stove, hence it gets too hot to hold. I followed your reasoning about reducing the capillary area with more channels, and think it makes sense. I will try to clean up, tighten my channels and see if that helps.
As for the JSB secondary hoop, I could see how such a feature would help ensure more uniform pressures in each of the channels/wicks/tubes, however it is not clear to me where and how to integrate this feature into the stove. Is it just formed in the space between the bent tabs (making an inner ring) from the collet and the bottom/outer bowl? Its some sort of azimuthal additional ring to balance channel pressures, but where is it and how is it made?
