Ravi: The first answer is NO, but May I offer a alternate idea. I use a
Nylon ( plastic )bolt to mount the ground wire to the outside of the
secondary coil. While the base end of the coil is at low potential it is
still a bad practice to provide a current path inside your coil form. The
plastic bolts are available from any plastic supply or your local auto store
to bolt license plates on.
