So, I'm kinda thinking it'd be cool to make some moon disks, like this
http://www.mooneyesusa.com/shop/prod...roducts_id=474,
only without the snap-on features and for model airplane use (yes, I'm
on a mission).

These are obviously spun -- but how do they do it? They're spun _all
over_, which leads to some obvious problems in part-holding. Do they
spin part of it, then change the holder, then spin the rest? What do
they do?

Anyone know? Anyone have a good guess?

I would guess that they are pressed blanks, edge turned over, then
polished. The perforations around the inside edge of the rim would be
done before the edge is turned over.
