Hi folks, nice proximity device pirate. Though I was wondering if anyone read my previous post about what to put on the ferrite toroids to prevent wire insulation scraping off, just wondering if there is a better solution than masking tape, although someone in other forum said some kind of spray on stuff, though not sure how effective spraying something on would be. Thanks.

Tyson:

I have never used anything to cover the toroids before winding and have never had a problem....well not as of yet anyway.  The only time I use magnet wire is for the secondary windings, everything else I used insulated wire.  All of my basic JT's use 22 ga. insulated wire.

Thanks for the compliment.

very nice setup

if i have a toroid with smooth edges i spray clear coat paint on them
if they have sharp edges i use electric tape (cheap-o- tape) its thinner

Hi pirate, thanks for the info. Hi kooler, thanks for the info., though I think ill stick with masking tape since its thin and can be pressed down around the curves well, though electrical tape would be fine on a bigger toroid im sure. thanks. Here is a pic of my toroid JT with first layer of secondary wound, 26 gauge 6T base, 12T collector, 30 gauge secondary. My intention is to try and light a fluoro with this, do you folks think i should add a few more layers, since I think it would need it. Your replies greatly appreciated, thanks.

oh and the secondary first layer is around 120 turns so far.
