You actually can't wind around the coil until it's
made.

You make it by winding number 16 gauge enamelled
wire
around a former (a drill shank will do) three
times.
Leave enough at the ends to atach the coil to
whatever.
Note - the wire will be a bit springy - you may
have to
use a slightly smaller former and allow it to
expand
to 3/16".

Hi
Is 3/16" the coil length ? And what's "enamelled wire" ? Isolated wire ? My
technical english dic ain't available at the moment.
