[QUOTE="DoneNOut, post: 2849723, member: 113404"] You know, you are hinting at something with this, although I wouldn't recommend your technique going about this. I am not a machinist either, but when I took a chambering class, Bob Pastor showed me how he uses a setting on the lathe to make the threads flat on top. Illustrating to me on a white board he showed how the "trapezoidal" barrel thread has more surface contact with the V threading channels in the receiver. Putting two Vs together creates issues as the two points wouldn't provide the same mating of the threads. OP - I managed to condition the threads on a savage shank via use of an Aero P. barrel nut. The nut spun on tight, I needed a towel and channel locks, but when I was done, those threads were proper flat on top and it's been a solid shooter. Just FYI. I know you might not have the exact nut, but hopefully picking up what I'm throwing down! :cool: [/QUOTE]
