The tire-rim stove may not be attractive, but it gets the job done

Sometimes saving cash is a simple matter of being able to
see "junk" as "raw material".

By William A. Shellberg
After installing a woodburning fireplace insert last fall,
I was pleased to note that my household's heating oil
consumption dropped from the previous year's nearly 800
gallons to a mere 50! So, when I noted that I was then
buying more oil for the small space heater in my
workshop/garage than for our entire home, I decided that
the utility building ought to have a woodstove of its own!
Now, I wasn't about to invest in a readymade
heater for my workroom, but I'm a pretty enthusiastic
do-it-myselfer and figured I could come up with a design
that would get the job done. I began my "research" by
visiting a neighbor who'd built a stove from kit-supplied
components and a pair of 55-gallon drums. I was quite
impressed with his heater, too. However, when I added the
price of the kit to the cost of the 30-gallon containers
that I wanted to use (the drums go for up to $15 apiece in
my part of Michigan), I decided to look for another
solution.
Not long after making that decision, I happened to be
rummaging around in my barn and noticed that I had a goodly
supply of old auto tire rims stacked in one corner. The
steel doughnuts are made of pretty stout material, and I
figured that a car-rim heater should last a long time! So,
I borrowed an arc welder and set to work.
I first cut the centers out of most of the rims that would
form the firebox and the upper "heat exchange" cylinder.
(The lower chamber, as shown in the photos, consists of
four welded-together 14" rims . . . while the top cylinder
is made from three.) Scrap pipe (for the legs) and sheet
metal (which I used to form the ends of the heater and the
pipe collars) finished the job. I recycled the 6" stovepipe
that had been used on the garage's oil-burner, but did have
to buy two elbows to connect the upper and lower sections
of my stove.
To protect the connecting pipe sections from early burnout,
I decided not to remove the center from the last
rim in my stove's firebox, hoping the obstruction would
serve as a baffle. I did cut the "innards" from
all of the rims forming the stove's upper portion, but
don't know that it was really necessary to do so.
