Thread: Home made safe

I've seen a vault that had a layer of synthetic binder twine, kevlar matting cutoffs and fiberglass sheeting wadded up and stuffed into a layer in the wall - on a test piece it bound up any cutting tools all to hell and anything reciprocating just bogged down in it. Might be an idea here if the AO didn't like it. You would probably need to demonstrate it on a test piece for them though.
