Casey - Thanks! I cut the chimney holes with a 2-1/16" (Starret, multi-purpose, yellow) hole saw. Then I used just a little 180 grit, then 320 grid sand paper to smooth out the hole. It's almost a good enough fit to be watertight without glue.
I'm not very knowledgeable about woodstoves, but I think the chimney (2-1/16" of course) might be too narrow for a good, long enough burn. And I think you'd need a separate stand, or want to hang it - pretty narrow to use the chimney as a stand. I don't think you'd want to add secondary vent holes since that would tend to focus the flame into the middle of the chimney; the laminar flow of heat up the sides is key in my design. But maybe things would be turbulent enough, and efficiency being less important with wood, that that would work.
Tallbloke - Yeah, the stove is just a fiberglass wick-filled, otherwise open, alcohol burner.
I've got two kettles, one made from a 23oz Heinekin keg can, which has capacity exactly 16oz, and the other from a 1L Asahi can, with capacity something like 22oz or 23oz.
A 15oz boil takes 7-1/2 minutes in the former kettle.
