For building up some small TCs, I'm looking for ideas on off-the-shelf
disks, say, 18" in diameter, made of an insulator that can tolerate
drilling holes or gluing. For the base of the TC and for a primary
support (I'm thinking of stacking them with sparkgap and caps below).
squares the same size would be ok. I've looked at things like plastic
cutting boards.
Plywood or masonite circles are available, and would work as a base, but
probably not right for the primary support (HV contact)
I've see serving trays of plastic, but they're black, and I'm leery of
black plastic for HV.
