A method of constructing a framework for a xerographic appar-atus in which it is desired to permanently attach steel tubing projections to an aluminum alloy main frame casting There are first cast separate plugs of aluminum alloy material up into the end of each steel tube (to approximately 3 inches depth) . Then the end of each such tube is mechanically staked to cause he tube's steel to flow into its aluminum plug. Each such integral tube assembly is then cut to the desired length. The aluminum plug ends are then welded directly to the alum-inum alloy casting to fasten the tubes to the casting at their desired locations.
