The white panel was cut from a retail advertising sign. Some kind of "plexiglas", but quite flexible and easy to work and cut- doesn't have a propensity to chip or shatter. About 3mm thick- I had to countersink the holes where the jacks fit so the nuts would attach. The brass mounting screws are just ACE hardware stock, with the knurled nuts. I first tried to attach them with epoxy glue, but that didn't stay bonded to the acrylic case. Currently, they are affixed with a healthy blob of 3M 5200 polyurethane sealant which is great stuff. Besides holding the screws solidly, it allows for a small amount of flex, which, I suppose, adds a anti-shock component to the build....This is smaller and much lighter than an ammo can (steel anyway). Not sure of the RF-resistant properties of acrylic.....;^) Aloha, Steve.
