Thanks to all who responded with their good ideas (and you too,
Lar). :-) I definitely want to be able to easily separate the top, but
don't want to run the risk of it moving around on its own. With that in
mind, I'm leaning towards using the dowel-pin locator approach, and
adding some molding which is fixed to the base.

I've looked at the various mechanical fasteners, and figure I can
always add them after the fact if I'm not pleased with how things turn
out. (Sort of a belt-and-suspenders approach.)
