Re: [TCML] Safely Grounding a Tesla Coil
Yes 8 foot,,I used a pipe about 3 foot long ,slipped over the rod,and
capped on one end as a Hammer.This gives a more concentrated blow to the
top,as where a large hammer dosen't meet the surface of the rod "flush
anf square",,,,also the pipe never misses,,as it is slid over the
rod.The bigger the weirht attached to this hammer makezs it more
effective.The weight added,can be ibternal or external.
Capich??
