Are there any construction articles around anywhere that describe an

That's the stepper motor controlled one.. Note that he used a switch to
switch between fixed inductors rather than a roller inductor. Also note
the comment about 3 months of evenings and weekends to build it.

Why not make a duplicate tuner of that which is in your radio now
except use
higher power units. You should be able to control this unit using the
existing
circuitry in the radio. Actually a purchased toroid transformer with
several taps would
probably the quickest way to go using a multipole switch.
