I took an old mouser rifle apart and I was looking at the machining of the receiver, it seems extremely complex. What intrigued me the most was the caming surfaces of the receiver as well as the caming surface of the safety lug raceway. How did they machine the caming surfaces on those old receiver? Did they use a shaper which advanced the cutting tool in to the receiver and rotate the receiver at the same time? Sounds like that method would have the potential of snapping the cutter easily, unless the cut was very shallow. BTW, how are the caming surfaces cut on more modern (i.e. simpler) action like the M-700 Remington or a M-70 Winchester? If there are any resources on the internet dealing with this topic I would like to learn much more on how this is done. Thanks
