>>13254705I helped construct a Faraday cage in our Lab at school, by doing all the soldering -- no one else knew how.
We used (sorta expensive) electrical-grade copper mesh (rather like rabbit fence) and silver solder.
We had to drill a hole through the floor down through the basement into the ground, for our cable to the grounding rod,
both from a lightning-rod company. It was a lot of work, even though the cage was only 6×4×8 feet.
