Re: Primary holder questions?

Original poster: "Dr. Resonance" <resonance@xxxxxxxxxx>

I usually mill them even with the top for a nice snap in. Another idea, if the coil is used near any small children in demos, if to mill it 1/8th inch deeper so a plexy topshield can be attached.

I am making a small 4 inch ID primary coil with 1/4 inch copper tubing stuffed into 1/4 inch thick Lexan with 1/4 inch holes and 3/8 inch pitch.
