    Hi, this is Ravi again, and i am almost done with my first TC, 7.5kV 
30mA, 3inX22in sec. I wanted to know some different ways to ground the 
secondary because i couldnt find a grounding strap. Could i drill a hole at 
the bottom of secondary and attatch  the wire with a nut and bolt? Please 
give me some ideas, i couldnt think of any other good ways.

Thanks for the help

Ravi
