I dont think that phenolic resin stuff was in liquid form originally; looks cut.

you are correct. phenolic is very close to fiberglass...that is a resin holds sheets of fiber ( I think cloth?) together making a very strong & light material. The stuff also stinks like shit when you machine it & makes one hell of a dust cloud. you can get the stuff in sheets...I have seen it up to 3" thick before. It would make a very good insulator. the stuff can be drilled & tapped ( tho I would use helicoil inserts in the threads ) & this looks like what they have done to me...built a box around the copper core.
