[TheForge] Wood Stove for Shop heat

While we're on the subject of wood burning shop
heaters. . .
About 20 years ago I lived in a quonset about 20 miles
out of Anchorage and voluntarily off the grid. I heated
with a single barrel stove but my job kept me out of
town so much of the time it was hard to cut enough
firewood to feed the beast.
A ways farther out of town is an old coal mine and
there were a couple of very convenient seams of the
shiniest prettiest anthricite you've ever seen. I could
pull my pickup right under them and literally pitch the
coal into the bed. About 3-4 hrs of digging and
pitching gave me a year's worth of coal heat so I
started burning a combo of wood and coal in the barrel.
In short order I'd burned out the botom of the stove
and had to make another. There was some really
excellent stoneware quality clay in the same strip
mine. The clay had too much coal particles in it for
most potters to want to mess with but the stuff was
perfect for ramming a stove liner with. So, that's what
I did in my next barrel.
Well, needless to say a horizontal barrel stove does
NOT make a good coal burner though used in combination
with wood it worked okay. I experimented with different
grate configurations but the stove was just plain the
wrong shape.
What I did was build a vertical barrel stove. I built
my own doors, One ash door about 10" x 5", slightly
larger than a fire brick laid on it's side. The fire
door was 12" x 12" and placed in the upper half of the
55 gl drum.
I rammed the bottom of the drum with the mined clay
about 3/4" thick and mounted the ash door flush with
the clay floor. I used split fire brick on end to line
around the bottom of the drum, leaving a gap for the
ash door which had a split brick cut in half on top of
it to make a continuous fire brick liner. I mortared
the split brick liner in with furnace cement.
After I'd gotten this far I noticed the split brick
liner made the bore slightly smaller than a bell
housing and I knew where I could find an old cast iron
one. After spending half a day digging in the wet silt
of Cook Inlet's Knick Arm and using a breaker bar and
cheater to snap off the hopelessly rusted on bolts I
took my trophy home. Sure enough the old bell housing
rested nicely on the fire brick liner. so I went about
making a grate and shaker mechanism for it. I welded a
plate over the opening for the clutch mechanism and it
was ready to install.
The drum I was using was an old highway paint drum so
it had a lid held on with a clamp ring. I replaced the
rubber gasket with asbestos rope. (this was quite a few
years ago and it was still available) the next thing I
did was cut a hole in the lid large enough to just
cover with a 15 gl. grease barrel which I welded to the
lid.
Looking at the stove's lid from the side it looked a
bit like a top hat, so that's what I called it or
alternatively the "heat hat". I then ran a 6" stove
pipe jack through the (now) top of the grease barrel.
After finishing a few little details like: a draft
that'd snuff it out if you shut it all the way down, a
6" sq. Pyrex window in the fire door and a nice shiney
chrome rim instead of legs, it was ready to try. I
ALWAYS test fire new home made wood burners outdoors
just because. This thing burned like a jet engine and
was very controllable so after playing with it for a
couple days I moved it inside.
The first thing I discovered when I lit it indoors was
I had to put a couple screws in the stove pipe cap as
the draft was so strong it just blew it off. Shortly
later I discovered it was WAY too much stove for my
well insulated little quonset and I ended up trading it
off with a neighbor who had a coal burning parlor
heater.
My neighbor Arvid used my vertical barrel stove in his
shop, a 62' x 90' quonset and it heated it nicely year
round. Arvid started sending his son and daughter with
a trailer with me to help mine the coal and I was
perfectly satisfied with the coal heater so everybody
was warm and happy. <grin>
