[QUOTE="J E Custom, post: 972310, member: 2736"] Not sure how everyone else does it, but first I square the contact surface with the bolt set up in the Lathe (Only enough to clean them up). Then while truing the action face I also square the receiver recoil lugs then everything is square to the world. The lapping is done to smooth the surfaces to aid in bolt lift and should be held to a minimum to prevent removing to much metal on one lug or the other. I set head space and lug contact without the firing pin assembly and the ejector plunger in the bolt to prevent a false reading. If everything is done right, when a round is chambered and fired everything will be if perfect alignment (At least as much as possible). Simply Lapping the lugs does not square them, it only gives them more contact surface. Just the way I blue print an action. J E CUSTOM [/QUOTE]
