RE: [TCML] question of construction - is metal okay at the center ofprimary?

["Stephen J. Hobley" <shobley@xxxxxxxxxx>]

I can speak from (internal arcing) experience that it's best to use nylon bolts for anything that isn't designed to conduct.
 
I do use a central metal grounding bolt in the base of the secondary, but everything else, top and bottom is nylon.

Hello,

Further to my construction question (thanks to DC for some tips) - I was
wondering if it was okay to have a bit of metal at the center of the
primary. I would need to place a few bolts there to hold the secondary
in place. Aren't eddy currents in that metal going to be a
problem/loss/source of heating??

Many thanks

Thomas
