> Find an Agway Store or other farm supply store. They have 1/4 mile spools
of aluminim fench wire at a very inexpensive price. The #17AWG works great
and its also good because it doesn't rust.
I'm curious... how do you bond the aluminum radial wires to their central
common point ...tig weld maybe?
Also, how long do you guess the #17 aluminum wire will last in normal soil
? Do you detect any oxidization causing a white powder to form from the
minerals in the soil? I considered the less expensive aluminum wire too,
but was worried about deterioration of bare aluminum in my harsh soil here,
so went with the #14 PVC covered solid copper as a precaution.
