Brett,

Some folks have problems with sparks shooting down through the
secondary form, but I never had that problem.  I leave my forms open
at top and bottom, and just put a wooden bar across.  I then attach
the toroid to that.  Sometimes I do close the ends, but i don't seal
it in any special way.  I don't get caught up in lots of unneeded
details, because most of my coils are for research, not looks.
I usually install a wooden post (broomstick) at the bottom of the
secondary, and this fits into a socket in the coil base or stand.
This lets me easily raise or lower the secondary for coupling 
adjustment.

I basically use the bolt method you spoke of.  I didn't have any problems.
