But remoting an antenna tuner means some small cheap motors to do the
work, and when scrounged, they won't cost much.


Yes, I've loads of those, and a fully-equipped (lathe, mill, etc)
metalworking
workshop to engineer such an arrangement, but currently it's devoted

for my 16mm narrow gauge gaden railway.
