Hi,
I am using a ground rod in the yard.
What I am doing with the cyl head is using it as a junction box per se.
The leads coming off the secondary, safety gap, NST and Variac I wanted
to keep short to I connected them all to the cyl head laying on the
floor a few feet away. Then I will bolt one long lead from the cyl head,
out to the yard where it will attach to the ground rod.
I glass beaded (like mild sandblasting) the entire head to it is
scale/oxidation free but it is dull in appearance.
Is this set up ok? Should I put the head on a piece of wood or plexi so
it is not right on the same floor that I am standing perhaps? It is a
cement floor and not dirt or wood so I figured I would be ok.

One other thing I wanted to ask. My secondary is just sitting there in
the middle of my primary. Does this need to be attached somehow so it
wont tip over or is just standing up ok? It does not seem to "tippy" but
I didn't know if during operation it could get knocked over somehow.

Jim

Let me see if I can sort things out. Yes aluminum is more lossy than
copper,
but less thas iron. so lets put it all in perspective. If you are making
a
compairison only if every thing is the same except one vairiable you can
compair. a cylinder head is not a piece of wire it is a casting of metal
with a large area and mass.Even a piece of graphite that size would
conduct
more energy than a copper wire.The earth surface resistance is more than
that would be, so wet the ground good and use it.Or you can drive a
copper
plated iron stake in the ground deep enough to match the sane area of
contact.Drive a piece of re-bar in a copper pipe and you have a ground
stake. What ever you use is better than nothing.
