Re: Primary Coil Placement
This works. I believe that both Malcolm Watts and Greg Leyh have
mentioned doing just that in past posts to the Tesla List.
Make sure that you have proper clearance between the primary
and secondary to prevent arc-over!
Be aware that the smaller diameter of the primary will mean
that you will not get much inductance per turn compared
to a flat spiral primary.
I would think that you would only use a primary inside the
secondary if you had some really good reasons to do so.
Greg mentioned cosmetic reasons for putting HIS inside,
and I got the impression that Malcolm put his inside just
for the joy of experimenting. Which is what it is all
about, isn't it?
Hope this helps.
