Abstract : A simplified method for assembling ammunition items -- which normally would require a threading, welding, crimping, or similar method for joining component parts -- was developed by the Ammunition Engineering Directorate's Application Engineering Laboratory. By machining or forming the proper configuration at interface of mating parts, items can be assembled by applying pressure axially in a standard press operation. The unique feature of this method is utilizing the components themselves as a tool to produce a curl interlock that has excellent holding characteristics. (Author)
