I was thinking that a power window motor off of most any car would make a
great driver for the rotor. I would just need to find or make the matching
gear for the mast.
I could also use small SPST momentary contact switches on a the outside of
a cog, wired to leds to indicate direction ( I have hundreds of leds and
about 30 of so small SPST's on hand.)
I would just have to make me a ring of led's in the shack and wire them to
the proper LED in the compass ring.
I also have some multi lead cable (there has to be 50 wires in this cable
that I picked up at an auction, it was in a crate I bought for $5)
To tell the truth, it sounds like a fun project.
The only hard part that I can think of is the gear for the mast pole.
