[TCML] Secondary to toriod ?

[stanley miller <swm334@xxxxxxxxx>]

Hi all,
 
I am wondering if anyone could explain why a zinc carriage bolt inserted into the center of a plastic cover, glued on top of the secondary, with the bolt head inside covered by a plastic cap would not work or be potentially dangerous.  This would allow the toriod to be completly adjustable, limited only by the size of the bolt.  I have never seen a TC with this sort of setup, it is always with standoffs or pvc piping rigged up in some way or something else.
Please correct me where my theory is wrong.
 
-If the secondary cover sits 1.5" to 2" inches above the last winding on the secondary the only thing that could still affect the bolt would be magnetic field which i do not see how it would hurt the bolt or shunt it in anyway.
 
-Since the toriod would be at the same potential as bolt there would be no fear of arcing to it.
 
-The bottom inside of secondary would have nothing metal to arc thru from top to bottom.
 
-since toriod capacitance is dependent on size wouldn't the bolt add a small amount to the overall capacitance of toriod
 
-I am embarassed to say i have an electrical degree and work in electronic field and am asking such a silly question.  ( but i do not pretend to know anything about tesla coils or high voltage for that matter!)
 
Thank ya all!
Stan
