I was taught option 2 in gunsmithing school at TSJC. I would make a mandrel and true up the face before barreling myself. I know of an excellent rifle builder who uses option 3.
55 degree threads? The threads are 55 degree form. I measured them by taking a silly putty impress and then comparing the form against a cutter of similar form. Then to make sure I cut a test stub which fits wonderfully well. After done I smoked the end of the receive and screwed up the stub hand tight. I got at least 270 degrees of impression on the face. I did not "blueprint" or true the front of the action. ie: option 1. And last, I decided the engineers at Steyr designed the gun to only interface with the receiver face so that is good enough for me. Its kind of like following the science.

I have 55 degree whitworth carbide inserts for just such a task, some modern tech works well and indexable threading inserts is one of those things.

SKB, that certainly would be a nice way to go, wish I could justify it. For me not really practical so I used my surface grinder and made my cutter from HS steel.

Well the barrel is finish chambered, 7x57R. Came out good if I do say so. I hadn't chambered a barrel for at least 15 years so had to remember a few tricks. Next is on to the takedown attachment. My plan is to have a screw with a stud on its end that will pin the barrel in place. To take it down you will back the screw out and then unscrew the barrel. Once that is done then onto fitting the forearm to both the barrel and buttstock. Then sight bases and sling loop.

Setup for inletting barrel. I hope I am not boring anyone but I have had a couple of followers ask to see setups and how I am doing things especially since it is a takedown. In the second pic your can see more clearly the endplates. Now for the nearly endless cycles of insert barreled action into the stock, remove it and carve away the black markings on the stock.

Finished inletting the barrel and I attached a couple pics. Now I have to finish the design for the forearm attachment hardware and then make the parts. Last, then inlet the parts into rifle stock

Thanks, I really appreciate the updates and pictures of your setups. This is the best thread that I've seen in a long time.
