Simon,

I use the strut method.  I take two flat type curtain rods, and cut
out two straight lengths, which are a little longer than the center
hole of the toroid is wide.  I leave the ends of the rods rough from
the hacksaw cutting.  Then I drill a hole in the center of the rods
and mount them criss-cross on top of secondary.   then I just
place toroid on top so rods "bite" in at center a little.  I guess they
could be epoxied in place or connected some other way also.
For a heavy toroid, stronger rods should be used.
