Hi Steve, Coilers,

That puts things into a different light and I now understand why you
wanted the greater distance.  Another list member suggested putting
the PVC conduits for the supply leads underground.  That is a great
idea if it can be done, but it's a tad difficult if your shop floor
is concrete like mine.  I still think you'll be OK if you keep them
flat on the floor/ground until within the radius of the strike rail
before coming up into the coil base to the tank circuit.  Putting a
safety gap at the PDT's HV bushings is good.  I use a horn gap made
from 1/4 inch copper tubing, set about 1/8 inch wider than the main
gap's setting.
