Anyone have any tips for securing fine-wire toroids in

A dab of hot melt glue or RTV. Or a Nylon screw through the middle. Or a
couple of holes in the board and a cable tie. The only thing to avoid
is laying it down flat on a solid copper plane.

Excuse my ignorance, but what is the problem with laying a toroid down on
a solid copper plane? I thought the magnetic field was contained within
the toroid and thus minimised external effects. I have completed a couple
of projects recently with some of the inductors like that and didn't
notice any real problem. Mind you, I guess they might have performed
better if not mounted that way )
