Hi All,
I've read quite a bit about making secondaries. In just about all of the instructions, it says NOT to drill holes in the secondary coil form. I understand that holes would give a place to arc into (or out of). BUT - if the hole were tapped and a nylon screw were put there, would the hole still be a problem (since there wouldn't be a hole any more)??
Tim,
It's still best not to use the screw or hole. Teh wire tends to corona and burn things up.
