  Thank your input. But I what I was hoping for was someone that already
is using safety gaps on their capacitors. This will enable me to just "
set it and forget it" without doing a lot of additional work and
research. I have spent too much time on this cap already! I have other
parts to this new coil to work on before my first test run.
