Bert,

Great work!  Sorry about the accident.  On one of our video reports, we
show
one of Alex Tajnsek's magnifiers taking a tumble just like yours.  We
didn't
even use hot glue.  It was his little "dynamite stick resontor".  The
12" by
2.5" diameter extra coil had 32 gauge windings and on top we put a 20"
diameter aluminum shroud and then on top of that a 60" diameter
industrial
aluminum hemispheric cover from a building fan.  All were balanced and
held
in place by the local gravitational field and precise center of gravity
alignment of all components.

  At 4 KVA input from the system's tank and driver coil.  The energy
traveled along a 12 gauge THHN house wire transmission line to the base
of
the resonator.  The output sparks were about 7 feet long.  The wire on
the
resonator got so hot you couldn't touch it.  In mid run (after about 1
minute) something must have moved because the entire arangement toppled
over
at full power and the terminal gear and resonator all crashed to the
floor
in a classic cartoon heap and the open, floor positioned, rotary gap was
slammed at full speed by falling debris which then recieved a new
tangental
velocity.  All caught on video much to our amusement.  

Typical TCBOR snafu and jerry rig testing procedures were followed to
the
letter.  Due to the lack of care and finish in the construction of all
components, all was put aright in minutes back to its former ad hoc
slip-shod construction standards and fired for another 5 minutes.
Ultimatley, we got almost 7.5 feet out of the little coil.  This system
is
seen in my book on the CSN minus the 60" cover.  In these photos we used
about a 36" domed fan cover for a terminal.  Lots of crash and burn
always
makes for a fun time.  Still, sorry about ole Wild Bill's nice spun
toroid
gettin' bunged up in your spill!
