Re: [TCML] calculating primary thickness and surface area

["Jared Dwarshuis" <jdwarshuis@xxxxxxxxx>]

I wasnt being condesending. You can use a heavy wire (suitable for the
current). It costs much less then tubing but is problematical as it
represents a strike point. (owing to its small radius of curvature).  Of
course minimizing materials means tightly spaced inductor winds.
Unfortunatly  when the turn spacing is tight, wire with its tight radius of
curvature becomes a source of arcing between turns.
I have wound over 600 ft of tubing for primaries this year alone, yes it is
expensive!

And you are welcome for the advice!
