I was just wondering how far down the "blueprinting" rabbit hole you might go.
I'm not a machinist, so please correct me if anything I say here is wrong. I'm out to learn.
What I believe I understand: Since you turned a fixture to face the action you have established the receiver threads in their present state to be the reference. Skimming the action face in that set-up then makes the plane of the action face perpendicular to the centerline of the receiver threads. It follows then that a carefully machined barrel tenon will snug up evenly against the action face with no binding or misalignment. Sounds good to me.
Here are my questions: How parallel and concentric is the receiver thread centerline with the rest of the action body? Are the bolt lug seats on one plane, and is this plane parallel the the plane of the action face? How does the plane of the bolt face relate to the others?
