[Stoves] Lo-fi ELSA stove

[David Young]

I have built the ELSA stove that's
documented here, https://www.youtube.com/watch?v=55r5DmvT3XE .

I started with a stainless steel trashcan that had seen better days.  I
unrolled it and glued on ELSA stove blueprints from the web.  Then I cut
out the shapes with a 24 tpi bimetal blade in a jigsaw.

I don't have an anvil, or the sheet-metal "curling" tool (is there a
name for it?) that is shown in the video.  I bent the metal over some
angle-iron, and I made the tool from some stainless tubing I bought at
the hardware store.

I couldn't get the stove to light until I used the lighting cylinder,
which is shown in the video, for some extra draft.  I used brown packing
paper as tinder, and wood pellets as fuel.

I attached a couple of photos.  One shows the stove itself.  You can
see that I'm an amateur fabricator.  The other shows the stove under a
kettle.  A lot of condensation forms on the kettle and, after the stove
has burned out, there is a thick layer of creosote on part of the kettle.

To avoid the creosote formation, I'm not sure if I should raise the
kettle to give the flame more time to burn out, or lower the flame by,
say, centrally introducing preheated secondary air---I am thinking of
Kirk Harris' design.
