Cutting internal cam relief

[Rmiller]

I have been working on building my own action and have been trying to figure how to best cut the cam relief cuts on the internal lugs. I done some searches but have not come up with much. I was wondering if any one had some good ideas for doing this .

Thanks RMiller
