SEJW: Coat Hanger Method - Shade Tree Repairs

An old farm mechanic taught me how to do this. I had asked him if we would
help me patch an exhaust system, and he refused. Instead he showed me how
to patch it myself with a torch and a clothes hanger on an old beat up
muffler in his junk pile.
I don't know what kind of wire a coat hanger is made of, and I am sure they
vary from manufacturer to manufacturer and even by age, but we used the
thinner newer wire hangers for this. (in the early 80s)
On a muffler with a hole in it, (but not totally rusted through) I was
showed to lay the clothes hanger across the hole and make small circles with
the torch mostly heating the tip of the "rod." When the rod was just about
ready to melt expand the circles to heat the thin metal body of the muffler
and let them flow together. Immediately remove the torch from the area when
it STARTS to flow or you will blow a hole in it.
Past the hole on the other side melt through the rod quickly and then repeat
to bridge the gap. Repeat the process with another piece layed right
against the first. When the hole is completely covered by a layer of short
clothes hanger rods. Use the same process of small circles to heat and flow
them together. The edge flowed in along the rod to the backing material is
the toughest, but with some patience it can be done as "neatly" as the ends.
It makes a strong solid patch on some pretty thin material, and over the
years I learned to use this same trick for a variety quick and dirty repairs
and fabrication projects. I've used it to make battery hold downs out of
cold rolled strap, and who knows what all over the years. It can fill a
gap, or bridge a gap. Its not pretty, but it works, and it will grind
easily enough.
I was told its "welding" not brazing. I learned to do it without flux, and
just burn the plastic coating off the clothes hanger rod as I go.
What made me think of it was the other thread here about repairing a cast
iron table. I don't know if it will work there or not, but I imagine it
wouldn't be very damaging to find out. As others suggested I'ld probably
back the repair with some angle or other material for added strength.
