Emmett,

You are still too high with the toroid.  The rule of thumb that I have
used with success is to have the bottom of the toroid about even with
the top-most turn of the secondary.  Another thing that will help is
to spiral the last few turns with an ever increasing pitch to the end
of the form.  The centre disk of the toroid then rests on the top of
the secondary form and is the point of attachment for the wire.
