[QUOTE="sable tireur, post: 1380902, member: 27307"] You can cut a thread relief just don't go too deep... [IMG]http://www.me.metu.edu.tr/courses/me117/Lectures/screw_threads_files/profiles.gif[/IMG] Please look at the 2nd illustration in the top row, American National. The crest on top of the thread form can be rounded or flat depending on the shape and type of tool being used. The root of the thread form should be either as well. Normally, we keep the crest of the thread form flat so that it doesn't touch the root of that thread, causing it to gall. The simple method is to cut the tenon diameter just a little smaller in diameter while cutting the thread to depth. Some folks use the full diameter then just run a file across the tops of the crest. Remember to dress the sides of the crest after this is done. No matter how it's accomplished, the crest should never touch at the root of the thread. The lock up is the face of the action and the shoulder of the barrel. This has to be perpendicular to the bore line. Over tightening a thread stretches the thread which can lead to galling also.
