RE: Covered primary

Hi
	I haven't tried covering the primary, but I clad a very leaky
and sparky secondary with a rubber car mat. It went around 2.5 times,
then secured it with plastic loom ties, very tightly. It stopped the bad
arcing to the primary, but I don't know if it stopped the pinpoint flashes
on the turns completely, as I obviously couldn't see the secondary any
longer ! After prolonged use, I dismantled this setup and there appeared
to be no more damage to the turns than before I covered it, so it seems
to have worked. Before this, I tried wrapping plastic insulating tape over
the whole secondary, in several layers. This burned through within a
couple of seconds of switching on ! The rubber gave none of this problem.

           Hi coilers!


               In regards to the advantages of covering the primary with
a protective 'sheet', (such as plexiglass) to avoid damaging 
discharge strikes. I was curious how such primary coverings
would affect coupling to the secondary? Also, has anyone combined
a covered primary with a secondary covering, (such as a acrylic
tube which would fit over the whole secondary)?

                                          Thanks for any thoughts.
