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. smile

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.

It has been so so cold here in Minnesota the last couple weeks progress has been slow. My shop is fully heat but I keep it at 45-50 and then turn up the thermostat when I plan on working. However its still cold so progress as I said has been slow.
Here are a few pics. As I have said this will be a takedown rifle so the pics of the mill are of the buttstock setup to get the end squared up and then drilled for the interface plates which is the last pic.

Often the job of setting up and clamping is more involved then the actual milling job itself. smile

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.

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