The process ensures uniform and precise fitting of an oversized bushing or cone-style compensator efficiently and straightforwardly. The two-piece mandrel is designed to thread together with the bushing or compensator positioned in between. A flat seat accurately locates the front of the bushing, while a tapered, hardened nose automatically centers the rear. This assembly can be mounted in a lathe or drill press, allowing for filing or turning of the outer diameter as required.
