2.Use the ruler to measure and mark both
1 H” pieces of 12-gauge copper wire 3/8”
from each end of the wire. This will give you
a visual guide to use when you flatten the
ends of the wire with the hammer.
3.Lay the wire pieces onto a hard, flat surface
and use a hammer to strike the end of the
wire with a firm tap, using the 3/8” mark
that you made on the end of the copper wire
as a visual guide on where to strike the wire.
You may need to strike the copper wire mul-
tiple times to achieve the flatness necessary
to allow sufficient space to drill the holes.
Do this step to both ends of the copper wire.
4.The ends of the copper wire will be sharp
after hammering them flat, so use a file to
eliminate any sharp or rough edges. After
filing the edges, use a fine grit sanding pad
to go over the area where you have filed to
smooth the edges and eliminate any file
marks. Do this to both ends of the copper
wire pieces.
