Thread: 5.6x57 single shot project

A little bit more work tonight.
We got the bush almost done, drilled and tapped the old firing pin hole to take a lightly countersunk M4.
Now I just need to file the remains of the screw down flush. Couldn't face it all the way down in the lathe as the face of the bush isn't perpendicular to the thread.
Once that is done we can turn the firing pin down.
A bit of difference between the new 67 thou hole and the original 100 thou hole!
