[TCML] High voltage glue and ferrite cores

[Jonathan Peakall]

Last time I did one (years ago) I used shellac as I was putting it together. 
Dries pretty fast, I think it's an ok dielectric, cheap and easy to get. I 
didn't wait for it to dry, I just kept going. Once it was wound and dried 
overnight, I dipped it in some of that "tool dip" type liquid rubber stuff. 
I worked that sucker pretty good, getting it quite warm many times and it 
held up. Still have it around here somewhere.
