I'm going to stack 2 x identical sheets of 3/4" plywood together in the new 24" rack.
The 127 lb Dahl 4H choke will sit dead center on the plywood. Is run of the mill
paint in a spray bomb conductive ? Or should I be using indoor latex, outdoor latex... or something else, like BBQ repair high temp paint ? Or perhaps fire resistant paint ?
2x2 angle aluminum down each side of rack, with plywood on top of em. 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.
I don't trust the insulation breakdown..... which is just a single sheet of....'fishtape' at bottom of each side of choke. Fishtape partially torn on one side. Each sheet is 21 x 22.75
Only the top sheet and front and rear edges to be painted. Its just for aesthetics. The choke is part of a C-L-C experiment I am playing with these days..for a B+ supply. 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.
