well, not going to be able to homebrew THAT former then !

What's wrong with, say, G-10 glass epoxy rod for winding RF chokes
around?

Is it flammability/gasses made in a choke fire that would make G-10 be
not preferred?

Hi Tim,
got no idea really - over the years I have sort of got used to things
bursting into flames occassionally(sp) hi hi , so dont worry about it
but just give it a go and see what happens. I also dont leave things
running un-attended, so am not the complete lunatic I would seem.

To me, the main criteria is whats on hand - there are not REALLY huge
voltages and currents there, so a bit of latitude in the materials
selection process seems to me, at any rate, quite reasonable.

No doubt one of the space shuttle designers on this group will promptly
debunk my theories.....

And yes, I sometimes DO represent the lunatic fringe of radio - guess I
never really grew up. But I have fun.....
