I am going to start making 2 inch by 10 inch tesla coil secondaries, and i want to make them look and work good. I am going to drill a small hole right about the last winding on the top and bring the wire inside of the secondary, and place a top cap on it so the buyer can drill a hole himself and insert the size bolt or breakout point that he needs.
But i am wondering how i should make the bottom termination. I would like to have a metal bolt and nut with the wire connected to it with a ring terminal on the outside, so the owner can attach their own wire to the ring terminal for the grounding wire, but i am afraid that will either cause racing sparks, or sparks to their primary.

arcing inside the secondary might be a problem.
Good point... Any other suggestions? Well actually i doubt anyone would get sparks that big from it, i mean it would have to be bigger that secondary length to arc on the inside. Or are you talking about wire to wire or something else?
Also, what should i use to coat the finished coil with? Anything good at home depot or lowes?

This topic was discussed at some length earlier this year (March), with many good suggestions given, including detailed photos of various techniques.
Search "secondary coil terminations", March 8 2008.
Also, any reasonably well designed and tuned Tesla coil should be capable of generating output arcs and streamers 1.5X - 2X the length of the secondary, so internal arcing can be a cause of secondary failure.
