[Amps] Non metallic paint for plywood ?

[Tom Hellem]

Jim-
How about using a piece of 1/4" or so thick piece of plastic on top of the plywood under the choke? Then you wouldn't have to worry about the paint.

Entire mess will  be up  off  the  bottom  just  enough so  I  can  get  my hands  underneath  to  tighten up the  1/4-20  nuts.   1/4-20  is  max  size  that  will  fit the  4 x slotted holes in  the 2 x angle  steel's,  at  base  of  choke.

Choke  has a 25 kv-65 A spst-nc kilovac ceramic relay  across it....  plus an  adjustable spark gap.  Spark  gap  is  just a pair  of  1/4-20 silver plated brass screws..with  1/4-20 acorn  nuts  facing  each  other.
