Then what I can do is to split the circuit in half of a varometer
and connect one in series with the positive and one in series to the
negative
so I have equal turns added or subtracted of opposite wound and
controlled by the single motor.
Sounds good

Not sure I understand what you mean. Comments by Roy, and
others, noted. All these methods are certainly valid. The first step is to
determine the actual impedance of your load before you attempt
to match it, and then design an appropriate network.
For measurement a vector network analyzer is the best method,
but expensive. The "TAPR" analyzer, by Tentec looks
good at $655. Most of the cheap analyzers are not very
accurate, and VSWR is not very useful.

The Smith Chart; provided by Dellsperger, at:
http://www.fritz.dellsperger.net/ is an excellent (free) tool for
matching network design. Also Chris Bowick's
"RF Circuit Design" (At Amazon.com) provides an
insight in the use of the Smith Chart.

Experimentation by variable: series L, shunt C, or shunt C, series L,
could provied a reasonable match. Others probably
have some practical idea.
