I also like the Impoverished Radio Experimenter's discussion of building
your own variable capacitors. He doesn't make it clear, though, how one
attaches the plates along the axis.

It doesn't really matter, as long as the plates move together and are
electrically connected. I don't have that publication, but if you're
talking about the usual "breadslicer" variable air capacitor, you could
drill a hole in each plate and stack them along a threaded rod with
washers between them, then clamp the stack with two nuts. You could
build the stator the same way, with differently-shaped plates to put the
mounting hole on a tab at the edge of the semicircle instead of the
center. The washers are probably the easiest way to get uniform spacing.
