Hi Gary,
As long as you have a good connection, it doesn't matter much how the
connection is made. This part of a coil is just not that critical. I
forget
how large a coil you are making, but of course as the coil becomes
larger
(4kW +) the connection becomes more critical. I've used all different
methods including many times just a clip lead on small (up to 2kW)
coils, and
it just didn't make any difference in the output spark length. If it's
a
small coil, I suggest that you do a test; first try a good connection,
tune
up the coil and measure the spark length, then replace the good
connection
using a simple clip lead, and re-measure, and I don't think you'll see
any
difference in spark length. In theory, a good connection is always
better;
in practice often no difference can be seen.
Looking for reality in coiling,
