ABSTRACT:
A method of and apparatus for making substantially impenetrable members such as wall and floor members for bank vaults or the like. A fixture is used which facilitates the assembly of a plurality of expanded sheet metal members in a spaced stack thereof. Rod members are inserted transversely of the expanded sheet metal members with at least some of the rods extending beyond the sides of the spaced stack of expanded sheet metal members. The fixture is elevated at one end so that the rod members may be secured to the expanded sheet metal members simultaneously in a number of different positions. An auxiliary frame member may be employed whenever it is necessary to align the sheets vertically prior to being secured to the rod members.
